Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
Preface
This is the material of the tenth Gas Transmission Network Development Plan for the ten-year period, for the 2018 – 2027 period. It was developed in coordination with the European Network of Transmission System Operators for Gas (ENTSOG) and in the process of two regional development plans. Moreover, we are considering the development of neighbouring transmission systems and neighbouring gas markets, we pay special attention to the domestic gas market, the development of natural gas consumption in the country, and thus the necessary development of the transmission system. Moreover, we are continuing with the in-depth analyses of natural gas consumption in the future.
The gas market is becoming more and more dynamic and insecure, natural gas flows in the transmission system and the natural gas consumption show growth, while the directions of natural gas flows have become increasingly unpredictable. We have recently used the term "dynamic market" only to describe the growing number of transmission contracts concluded for periods that began to shorten, and now this concept has expanded to all areas of our operations. The vibrancy of the market affects the scope of our work, business operations, and the planning of what the transmission system needs for its operation.
The concern for reliable, safe and economical operation of the transmission system is at the forefront and properly covered in this document. We have analysed the presented projects, prioritised them and determined their implementation time line, using the prescribed procedures and tools. Our guiding principles were our assessments of the role and opportunities of natural gas as an environmentally- friendly energy product at the national level and in individual areas of the country.

Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
Summary
The Slovenian gas transmission system is part of the energy infrastructure of national importance that is present in 108 of the total 212 Slovenian municipalities. In the energy balance sheet of the Republic of Slovenia for the year 2016 it was estimated that in the final energy consumption structure the share of petroleum products will stand out with 46.5%, followed by electricity with 22.5%, renewable energy sources with 13.8%, natural gas with 12.1%, heat with 3.7%, industrial waste with 0.8% and solid fuels with 0.7%. As an energy product, compared to the European average, natural gas has a much more modest representation in the national energy balance sheet, with the exception of industrial consumers sector.
The transmission system operator (TSO) measures the demand for natural gas transmission in the domestic energy market based on queries, approvals issued and connection contracts concluded with distribution system operators (DSO), industrial users and electricity producers. In 2016, there were 54 queries, 7 approvals for connection were issued and 4 connection contracts were concluded.
Regarding the purpose of the gas projects in relation to security updates, development of domestic gas market and harmonisation with international projects, the TSO breaks down the planned infrastructure into 3 groups. Group A contains 18 projects to increase operational security, i.e. loops and adjustments to the pipeline system due to settlement and other circumstances. Group B contains 58 connections. Group C contains 17 projects for the development of interconnection points with the transmission systems of neighbouring countries, which include 4 projects that have been listed as projects of common interest in November 2015 by the European Commission. Regarding the achieved maturity of individual projects, the TSO estimates that it will implement (construct or begin construction on) 18 pipeline projects in the three-year period of 2018 − 2020, 8 of them planned.

Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
Introduction As the TSO in the Republic of Slovenia, the company Plinovodi is obliged in accordance with the provisions of the Energy Act (EZ-1)1 to adopt and submit for confirmation to the Energy Agency a 10- year network development plan every year after consulting the relevant stakeholders. The plan must be based on the existing and expected supply and demand and include efficient measures in order to guarantee the adequacy of the system and the security of supply.
The purpose of the Ten-Year Gas Transmission Network Development Plan for the 2018 – 2027 Period (hereinafter: Development Plan) is to:
Determine the main infrastructure for transmission that is to be built and upgraded over the next years for players on the market, Contain all the investments that have already been decided and identify new investments that have to be carried out within the next three years, Provide a time frame for all investment projects.
When preparing the development plan, the TSO has formed reasonable assumptions on the development of production, consumption within the domestic energy market and exchanges with other countries. It has taken into account the investment plans for regional networks and EU-wide networks as well as investments for the natural gas storage facilities and liquefied natural gas (LNG) re- gasification facilities.

1 Definitions
Unless the meaning of an expression is otherwise defined in an individual section of the development plan, the expressions and units of measurement used have the same meaning as defined in the applicable legislation.
2 Consultations
2.1 TSO's consultations with stakeholders
Between 6 April and 1 May 2017, the TSO published a draft of the development plan on its website. Within the public consultation procedure, it has invited all interested public representatives to present comments, suggestions or additions to the draft. During the public consultation process, which lasted for one month, it has received 4 responses. It has researched all of the responses, taken them into account and explained the reasoning to the interested public. All neighbouring TSOs have also been notified of the development plan draft beforehand, and we have received 2 responses.
2.2 Activities of the Energy Agency in relation to network development
The Energy Agency carried out a consultation procedure with all actual and potential system users by publishing the development plan on its website and inviting them to submit their remarks. The consultation procedure was concluded on 10 July 2017.

3 Supply and demand for transmission capacity of Slovenian natural gas transmission system and natural gas supply
3.1 Current situation of the natural gas transmission system In terms of flows of natural gas in Europe, the geographic position of Slovenia is fairly favourable. It is in close proximity to the transmission routes from north eastern Europe (from Russia through Slovakia and Austria towards Italy and Croatia) and bordering on Italy, where the transmission routes from the Mediterranean Basin and northern Europe converge. Moreover, the Slovenian system is in the vicinity of the existent and newly planned LNG terminals in the Adriatic Sea.
The Slovenian gas transmission system comprises 1,156km of pipelines, two compressor stations in Kidričevo and Ajdovščina, and 245 metering and regulation stations or other stations. At key points, the gas transmission system is equipped with devices through which the system can be controlled and maintained. The remote control and monitoring functions are carried out by means of an information and telemetry system.

The gas transmission system connects most of the industrial and urban centres in Slovenia, with the exception of the Obalno-kraška region, Bela Krajina and part of Inner and Lower Carniola.
The gas transmission system is controlled and monitored from the dispatch centre that is connected to the dispatch centres of transmission systems operators of neighbouring countries, as well as to distribution network operators and major consumers of natural gas.
A major part of the existing gas transmission network is older than 30 years.

The Slovenian natural gas transmission system began its operations in 1978, and was then gradually expanded and upgraded. In 2014, the last major investment cycle was completed with the construction of a pipeline from the Austrian border at Ceršak to Vodice near Ljubljana. In addition to providing additional necessary transmission capacities, the safety and reliability of the transmission system operation were improved. With regular inspections and regular maintenance work, the company Plinovodi d.o.o. as a transmission system operator ensures safe and reliable operation of the transmission system. The status of transmission pipelines is regularly monitored by supervising pipeline routes, by performing internal inspections of gas pipes, by using various methods of external gas pipeline inspection, and by constantly monitoring the operational parameters via the central control system. With the cathodic protection system, transmission pipelines are protected against the development of corrosion damage. Based on preventive inspections and maintenance work, we estimate that the gas infrastructure is in very good operating condition; so far, we have not had any major operational problems that could not have been managed in the framework of the planned maintenance interventions.
3.2 Domestic market
3.2.1 Supply of natural gas to Slovenia and access to natural gas sources
Due to the lack of own sources, the supply of natural gas to the Slovenian market depends entirely on imports. The supply of natural gas to Slovenia takes place from Russia and individual hubs of the
8
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
European gas market. From Austria, natural gas flows via the Ceršak entry point, and from Italy, via the Šempeter entry point. Natural gas, located in the trading hubs of the European market, is been pumped out both in Europe, as well as in North Africa and Russia.

Through the interconnection 100% point Ceršak, the TSO can supply 90% all Slovenian consumers, 80% regardless of their location. This 70% is also reflected in the positive 60% trend of increasing the share of 50% supply via the Ceršak point in 40% Figure 3.

3.2.2 Slovenian Energy Concept − orientations
The Slovenian Energy Concept (Energetski koncept Slovenije – EKS) is in preparation. In accordance with the Energy Act (EZ-1, Official Gazette of RS, Nos. 17/2014 and 81/2015) and the projection of economic, environmental and social development of the country and along with the adopted national commitments, particularly those related to energy and climate, it will provide a basis for identifying ways for their achievement in the future.

Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
The consultation document presented by the Ministry of Infrastructure (MoI) at the beginning of the consultation process in May 20153 outlines the key elements for directing Slovenia's transition into a low-carbon society, to which RS has already agreed in the past when adopting national commitments within international obligations.
As an energy product, compared to the European average, natural gas has a much more modest representation in the national energy balance sheet, with the exception of industrial consumers sector. From responses to the material that the MoI has prepared on the subject of EKS so far and from last year's discussions on energy sources4 it can be summarised that natural gas will keep playing an important role in the energy sector in the future. In the discussions, natural gas has been recognised as an important energy product that is important for district heating systems and for individual energy systems. Natural gas is classified as low carbon fuel, since it produces a negligible amount of dust particles and substantially fewer emissions (CO, NOx, etc.) than in fuel oil, gasoline and diesel, petroleum gas and biomass5. In order to achieve the national objectives of greenhouse gas emissions6 it will have to replace coal in district heating systems in at least the next five years and gradually replace fuel oil as well. Natural gas plays a special role in transport in two directives7,8 that describe it as an alternative fuel to fossil fuels in transport. In accordance with the aforementioned directive, a national strategy9 for the required infrastructure should already be prepared in the current year.
Development of the transmission system is crucial and directed towards expanding the networks and establishing more efficient connections with distribution systems and the neighbouring transmission systems in the region. There is no doubt that the national energy-climate goals can only be achieved through the efficient use of several energy products, therefore combining the functions of their transmission systems and distribution systems or district heating systems. A higher degree of gasification in the country would contribute to this goal. The TSO is striving to develop and upgrade the system to increase the level of diversification, i.e. obtaining new sources through new routes, including the LNG (liquefied natural gas) terminals and access to natural gas storage facilities.
3.2.3 Existing supply of transmission capacity as of 1 January 2017
The TSO publishes the data on transmission capacity of the gas transmission network for relevant points that are shown in Figure 4 and confirmed by the Energy Agency. Five relevant points are displayed, four of which are cross-border interconnection points and relevant points for the publication of data, while the fifth relevant point is aggregate information on the combined exit/transmission for users in the Republic of Slovenia.

By monitoring the demand for additional capacity on the domestic gas market and the demand for cross-border transmission capacity and in accordance with the requirements for ensuring a secure supply of natural gas, the TSO is obliged to develop the transmission system to ensure all of this.
Pursuant to Regulation No. 715/2009/EC, the TSO must provide system users their separate use of transmission capacity at all entry and exit points to the system (as per the so-called system of entry-

To ensure successful operation of the entry-exit points system, the TSO must provide appropriate technical conditions such as the elimination of bottlenecks on the transmission system in order to enable suitable marketing and booking of capacity under this method and to allow the booking of capacity at entry and exit points in various combinations.
With the introduction of transmission capacity booking via the auction platform PRISMA and with the implementation of a virtual point in Slovenia, there was greater dynamics of both the booking of transmission at the cross-border interconnection points and the transmitted quantities.
3.2.4 Infrastructure standard and compliance with Regulation 994/2010/EU
The Regulation (EU) 994/2010 of the European Parliament and the Council concerning measures to safeguard security of gas supply introduces the so-called "infrastructure criterion N-1" stipulating for the subject geographic area that in the event of interruption on an individual largest gas infrastructure there must be sufficient technical capacity available to meet the entire daily demand for gas, even in cases of exceptionally high demand (peak consumption).
By 3 December 2014, Member States were obliged to adopt and implement measures to meet the infrastructure criterion N-1. When preparing the Regulation 994/2010/EU, The European Commission has taken into account that the circumstances in Slovenia are rather specific compared to other Member States. Slovenia has no natural gas storage facilities or liquefied natural gas plants and in addition to that, the Slovenian transmission system is connected to foreign transmission systems in only three handover points. For these reasons, Slovenia (along with Luxembourg and Sweden) is an exception and therefore not obliged to meet the criterion N-1. This exception applies as long as Slovenia maintains at least two interconnectors with other Member States, at least two different supply sources and no natural gas storage facilities or liquefied natural gas plants. Under Regulation 994/2010/EU of the European Parliament and the Council, Slovenia is obliged to submit a report to the European Commission by 3 December 2018 describing the circumstances regarding infrastructure criterion N-1. On the basis of that report and as long as the conditions for exemption continue to be fulfilled, the European Commission may decide to extend the validity of the exception.
When dealing with transmission capacities at cross-border interconnection points, the analysis of the infrastructure standard was adjusted for the last Risk assessment for security of supply, prepared by the competent authority (Energy Agency), and for the Ten-Year Network Development Plan 2018 − 2027 in the light of analyses in the previous years. When calculating the infrastructure standard, only the firm transmission capacities were taken into account as technical capacities of cross-border interconnection points, without taking into account the possible specific measures of the transmission system operator to provide additional interruptible transmission capacity in the event that supply security is threatened. The technical capacities of the subject cross-border interconnection points are defined on the basis of flow-pressure calculations of the transmission system, taking into account the technical capacities of all the transmission system components included in the transmission (gas pipelines, metering and regulation stations, and the two compressor stations), as well as the operational characteristics and operational boundary conditions of the transmission system as a whole.
The estimations of value increments of infrastructure criterion N-1, inter alia, also depend on the estimated growth of the peak load of the system. In the estimation of the development of peak load of the Slovenian transmission system it was taken into consideration that the peak load will increase in the coming years due to the growth of wide consumption.
12
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
Based on the analysis of prospective infrastructure projects, the TSO has estimated that the infrastructure standard N-1 will range between 57.4% and 56.8% in the next two years. In the long term, the TSO estimates that it can ensure the development of infrastructure standard N-1 for the Slovenian transmission system in a manner that will allow the system to reach the required level of 100%.

Figure 5. Estimation of infrastructure criterion N-1 development for the Slovenian transmission system
As the TSO, the company Plinovodi will be able to meet the requirements of the infrastructure criterion N-1 in the long term by:
1. establishing entry capacities and therefore enabling physical flow from the direction of Croatia via the cross-border interconnection point Rogatec (planned in 2019); 2. an additional connection of the Slovenian transmission system to neighbouring systems that could be realised within the Hungary connection project (planned in 2021).
The development of the infrastructure criterion N-1 in the coming years will be strongly influenced by the development of the peak load of the system, which the criterion defines as "the entire daily demand for gas on a day of exceptionally high demand for gas". In the estimation of the influence of peak load development on the infrastructure criterion N-1 it was taken into consideration that the peak load of the system will increase in the coming years due to the growth of the wide consumption peak. The development of peak load in Slovenia will also depend on the booking of transmission capacities for gas power stations.
Pursuant to Article 7 of Regulation 994/2010/EU, the TSOs must implement a procedure for enabling bi-directional capacity or for exemption from the obligation of enabling bi-directional capacity for each cross-border interconnection between Member States:
1. Enabling bi-directional capacity at cross-border interconnection Šempeter/Gorica
With the successful completion of the investment cycle on 1 January 2015 the TSO Plinovodi enabled bi-directional capacity at cross-border interconnection Šempeter/Gorica where bi-
13
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
directional booking of transmission capacity and bi-directional operation of the transmission system was taking place in 2015 and 2016.
2. Exemption for reverse flow capacity for cross-border interconnection Murfeld/Ceršak
The TSO Plinovodi obtained the exemption from obligation of enabling bi-directional capacity at the cross-border interconnection Murfeld/Ceršak in accordance with the 4th paragraph of Article 7 of the Regulation 994/2010/EU without restrictions. Article 7 of the Regulation 994/2010/EU defines the repeat process for "enabling reverse flow capacity or exemption" on the basis of Risk assessment for security of supply, which is carried out every 2 years in accordance with Article 9 of the Regulation 994/2010/EU. The latest Risk assessment by the Slovenian competent authority for security of supply that was carried out in 2014 in both Austria and Slovenia has so far not indicated the need for enabling bi-directional capacity at the cross-border interconnection Murfeld/Ceršak.
3. Exemption for reverse flow capacity for cross-border interconnection Rogatec
Based on the Risk assessment for security of supply, the TSO Plinovodi submitted the application for exemption from the obligation of enabling bi-directional capacity with the possibility of reverse flow from Croatia to Slovenia in 2016. It obtained the exemption for cross-border interconnection Rogatec until 31 December 2018.
The risk assessment has taken into account that reverse flow capacity at cross-border interconnection Rogatec could affect the infrastructure standard of the Slovenian gas transmission system, but not before the Croatian transmission system is upgraded with compressor capacities for transmission of gas to cross-border interconnection Rogatec and for ensuring the necessary pressure conditions at this interconnection point, which would according to the time frame for the upgrade of Croatian transmission system be possible at the end of 2018 at the earliest.
The technical solution to provide bi-directional capacity with reverse flow in Rogatec depends on the size of the requested transmission capacity. The most basic scenario would require an upgrade of the border metering and control station in Rogatec on the part of Slovenian TSO and an upgrade of the transmission system with compressor capacities on the part of Croatian operator.
In the company Plinovodi we actively participate in all activities in the region related to the development of new or existing transmission directions. For the existing transmission direction Austria − Slovenia − Croatia, an analysis and technical design was performed to establish bi-directional capacities in the direction Rogatec − Ceršak (the project of the conceptual solution "Transmission pipeline M1 Ceršak − Rogatec and M1/1 Ceršak − Rogatec, Enabling bi-directional capacities with reverse flow", manufactured by IBE d.d., January 2015). In 2017, the increased capacity for the cross- border interconnection Murfeld/Ceršak is performed in cooperation with the Austrian transmission system operator Gas Connect Austria, via an auction of bi-directional capacities. Other activities for enabling bi-directional flows are also included in the development plan of the company Plinovodi, where the upgrades of the transmission system at the border metering and control station Rogatec, at the compressor station in Kidričevo, and at the border metering and control station Ceršak are planned.
We are just awaiting the publication of the new European Regulation 994/2010/EU concerning measures to safeguard security of gas supply, which builds on the substance in the preparation of the
14
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
Risk assessment, as well as in the field of implementation of preventive measures and measures in the event of an emergency. The requirements of the new regulation will be taken into account in the preparation of the following Risk assessment and Acts for securing the supply of natural gas.
3.2.5 Supply and demand for transmission capacity – territorial coverage
As of 1 January 2017, the TSO had transmission contracts concluded with 147 system users, namely 14 DSOs operating in 81 municipalities, 131 industrial or commercial consumers and two power stations.
Figure 6. Regional availability of the gas transmission network
The connection to natural gas can be performed in 81 Slovenian municipalities, which have an operating gas network and in which 14 distribution system operators provide natural gas supply.
Based on the assessment of the potential of natural gas consumption, the distance of the municipality from the transmission system, the estimation of the value of the connection implementation, and the informative calculation of economic viability, the TSO estimates that there are 68 more municipalities where the implementation of the connection is reasonable.
In addition to households, for which the DSO would construct a network in densely populated locations, the other critical factor to decide whether to connect a local community to the transmission network is the transition of other industrial and commercial users to natural gas (schools, kindergartens, hotels, hospitals, stores, crafts and the like). The connection projects are divided into municipalities that could connect through existing MRSs, municipalities to which it would be necessary to construct a connection pipeline and a new MRS and municipalities whose connection depends on a previously constructed longer system pipeline.

In the year 2016, the largest share of energy consumption was in traffic. Industry and households represent an important segment of energy consumption as well. These three sectors have consumed nearly 89% of all energy, with the remaining 11% in other consumption, non-energy consumption and the energy sector. In Slovenian industry in 2016, natural gas represented 35% of consumption. One of the most suitable uses for natural gas lies in households, since it is easy to use, safe, as well as the most environmentally friendly and competitive. There are several reasons for its small share (10%) in Slovenia, the relatively small geographic coverage In comparison with 2016, the energy distribution by sector in Slovenia in the year 2006 was: industry 25% (last year 33%), traffic 39% (last year 30%), households 24% (last year 23%), other consumption 11% (last year 10%), non-energy consumption 1% (last year 4%).

3.2.7 Natural gas consumption in the country in the 2008 – 2016 period
The past consumption of natural gas represents one of the indicators used to forecast the booking of transmission capacity. In the year 2014, we have seen a large drop in consumption of natural gas, especially in the electricity production sector. The consumption of natural gas in the industrial sector has stabilised in the period from 2012 to 2014, which suggests that the economic conditions have settled down somewhat, and in 2015 there has been an increase in natural gas consumption in the industry segment of about 6%, and then in 2016 the additional 2.5%. In the other consumption segment, the TSO has been noticing a decline in natural gas consumption until 2014, which the TSO attributes mostly to installation of efficient facade insulations, new energy-efficient windows and other structural elements that contribute to lower consumption of energy products for heating, as well as extremely mild winters, but in 2015 an increase in natural gas consumption has been noticed in the other consumption segment as well, approximately 13%, and the additional 7.5% in 2016. Therefore, a total increase of about 4.5% has been recorded in the consumption of natural gas quantities in 2016 in comparison with the year 2015, and as much as 14% in comparison with the year 2014. Regardless of the annual volume of natural gas consumed, from the TSO's perspective, the key is the capacity booked on the level of daily consumption, required for the transmission of natural gas to supply the network users, which remains at about the same level during peak loads.

3.2.8.5 Deployment of alternative fuels infrastructure
The purposes of Directive 2014/94/EU on the deployment of alternative fuels infrastructure are minimising the dependence on oil and mitigating the environmental impact of transport, and it opens up new opportunities for natural gas in road and maritime transport.
The natural gas transmission system with the requisite development can represent an important support infrastructure for transport, which is why we are co-developing the national framework in the direction where natural gas in transport is first attributed adequate relevance due to its positive role that is already proving in many cases of good practice to reduce emissions of particulate matter and to a lesser extent CO2, and afterwards, that it becomes interesting for users, if necessary with the help of suitable financial incentives.
Projects within the framework of alternative fuels infrastructure are discussed in Point B8 CNG MS/MRS (connection of users with CNG filling stations).
The national strategy for the development of alternative fuels infrastructure, dictated by the Directive 2014/94/EU, is currently under preparation and will be adopted by the Government of Republic of Slovenia expectedly in October 2017.
3.2.9 Forecast of natural gas consumption and booking of transmission capacity for the 2018 – 2027 period
The forecast of booking of transmission capacity of the system operator is a key element of the review of future development of the natural gas market and it is based on numerous elements that the transmission system operator includes in the preparation of the forecast, namely:
the concluded contracts for the connection to the natural gas transmission system and transmission contracts, the demands received from existing and potential network users, past experiences with transmission system users and implementation of TSO's activities in terms of new connections, forecasts for the construction of power facilities, estimated transition of system users to the increasingly higher use of short-term transmission capacity, prepared estimates of transmission capacity booking from the Requirement to issue consent to the regulatory framework, tariff items for network charges and tariff items for other services for the regulative period from 1 January 2016 to 31 December 2018, and the estimates and forecasts that the ENTSOG prepares and uses in the preparation of the TYNDP (ENTSOG has included various scenarios in the methodology for the last TYNDP 2017, and the company Plinovodi pursued the goal of steady growth in the consumption of natural gas).
24
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
The forecast for the booking of transmission capacity for electricity production is provided in Table 11 and is based on the following assumptions:
it takes into account the existing contractual booking of the Šoštanj TPP, the booking of the Brestanica TPP is assessed at the level of the 2015 booking, the start of first-stage operations of the TE-TOL gas thermal plant is planned in accordance with the contract.

Figure 18. Estimate of the booking of transmission capacity for the 2018 − 2027 period
When preparing forecasts for the future booking of transmission capacity, the TSO uses different sources. Due to increased dynamics and an evolving natural gas market, the TSO warns that long-term 25
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
forecasts, i.e. forecasts exceeding 3 years are in fact indicative forecasts that depend on various factors that cannot be directly influenced by the TSO. The most reliable source of forecasts used by the TSO are the agreements and contracts that have already been signed. The TSO has observed an ever more pronounced trend of short-term booking of transmission capacity, as network users tend to use short-term services more and more frequently. The increasing liquidity and liberalisation of the natural gas market provides additional opportunities for system users, while increasing the flexibility of natural gas supplies and reducing the reliability of the forecasts of transmission system operator bookings. The demand received constitutes an important source for the preparation of forecasts, but is very limited in terms of duration. When preparing forecasts, the TSO also monitors the development of the domestic and foreign energy markets and the plans for the construction of power facilities. The TSO continuously monitors the competitiveness of transmission routes in the region in order to ensure the proper competitiveness of the transmission route through Slovenia.
The TSO has prepared a forecast of natural gas consumption on the domestic gas market in the next ten years, which is presented in Table 13.
Table 13. Forecast of natural gas consumption on the domestic gas market (in million kWh/year) Sector 2018 2019 2020 2021 2022 2023 2024 2025 2026 2027 Industry 5,239 5,291 5,344 5,397 5,451 5,506 5,561 5,617 5,673 5,729 Other 4,099 4,140 4,181 4,223 4,265 4,307 4,351 4,394 4,438 4,482 consumpti on Electricity 50 50 2,136 2,136 2,136 2,136 2,136 2,136 2,136 2,136 Total 9,388 9,481 11,661 11,756 11,852 11,949 12,048 12,147 12,247 12,347
In preparing forecasts for future use of natural gas, in addition to other elements the TSO takes into account the individual forecasts of stakeholders on the natural gas market and the general forecasts of natural gas market development and economic growth. The forecasts have taken into account the energy efficiency measures, but the TSO estimates that their impact will be superseded by the increased use of the energy product.
3.3 Cross-border transmission capacity and booking
The Slovenian gas transmission system is connected with the gas transmission systems of the neighbouring countries via cross-border interconnection points that are managed by various TSOs. The cross-border interconnection points of the Slovenian TSO with the neighbouring transmission systems are made with:
the Austrian TSO, Gas Connect Austria, at the Ceršak cross-border interconnection point, the Italian TSO, Snam Rete Gas, at the Šempeter cross-border interconnection point, and the Croatian TSO, Plinacro, at the Rogatec cross-border interconnection point.
For the purpose of cross-border trading and transmission, the capacity needs to be booked at the respective cross-border points and in the corresponding direction. The booking of transmission capacity is carried out according to the model of entry-exit points, where the system users have been provided with a separate and independent booking of transmission capacity at each cross-border interconnection point. In this manner, the system user carries out cross-border transmission of natural gas from the territory of another country via the Slovenian territory to a third country, which facilitates and promotes the establishment and operations of the Community's internal market. As of 1 November
26
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
2014, the booking of transmission capacity at the cross-border interconnection points is carried out via the joint online booking platform PRISMA by the principles of auctioning and for the capacity booking products in accordance with the Commission Regulation 984/2013/EU.

3.3.1 Demand for booking at cross-border interconnection points
The requirement for carrying out cross-border transmission of natural gas is to book a suitable combination of transmission capacity at cross-border interconnection points. The TSO keeps the interested public informed of the available transmission capacity of the transmission system via its homepage, the auction platform PRISMA, and the ENTSOG transparency platform. In 2015 and 2016, the TSO received increased demand at cross-border points predominantly for the booking of transmission capacity in the direction of Croatia, and cross-border transmission in the direction of Italy. The TSO finds that the number of bookings of transmission capacity depends primarily on changing conditions on the neighbouring natural gas markets, while the bookings of transmission capacities in the direction of Italy are mainly related to the extremely cold periods and periods of high electricity prices, particularly on the Italian and French markets. In addition to the situation on neighbouring natural gas markets, the implementation of the virtual point and trading platform in Slovenia is also affecting short-term bookings of transmission capacity. Members of the trading platform are performing daily and intra-day transmission capacity bookings for transmission of purchased natural gas to neighbouring gas markets and for the purposes of ensuring the balance of the transmission system.
Possible alternative natural gas transmission routes in the direction of Italy, Croatia and Hungary are either relatively occupied or their costs are less favourable. The model of entry-exit points and the possibility of transmission capacity booking via auctions on all gas markets in the region has established a standardised and simplified procedure of transmission capacity booking that allows users of the transmission system greater flexibility and responsiveness to dynamic price changes on individual gas markets.
27
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
The key role in the provision of transmission capacity booking at the cross-border points as seen by the stakeholders on the gas market is the situation in the natural gas market, because users optimise their portfolios. With the implementation of short-term products, users have gained additional optimisation options, while at the same time the TSO notes the transition from long-term bookings to short-term bookings of transmission capacities. All this suggests that the implementation of long-term forecasts for the booking of transmission capacity is unpredictable.
3.3.2 Booking of transmission capacity at cross-border interconnection points in 2016
In 2016, capacity booking at cross-border interconnection points was mostly carried out through the auctioning process and exclusively via the online booking platform PRISMA. The TSO has been publishing the available firm and interruptible capacities at cross-border interconnection points on a daily basis on the booking platform and allowed the transmission system users to conclude contracts of various maturities (annual and multi-annual, quarterly, monthly, daily and intraday).
Similar to previous years, the most occupied and utilised transmission direction in 2016 was in the direction from Austria (Ceršak entry) towards Croatia (Rogatec exit), where increasingly more short- term contracts for the booking of transmission capacity were being concluded in addition to long-term contracts. Considering the capacity bookings at cross-border interconnection points and the share of transmitted quantities (Figure 3) in the recent years, it is evident that the trend of bulk natural gas transmission and booking from the east supply direction via Austria has carried on in 2016. Due to commercial reasons, this direction is very interesting for all domestic, as well as foreign system users.
Considering the available possibilities for the booking of transmission capacity with the TSO, it offers the system users the products of various maturities and at the cross-border interconnection points via an auction process. Figure 19 shows the dynamics of the booking of transmission capacity in 2016. From the introduction of the model of entry-exit points, the stated graphs show the increased daily dynamics of bookings throughout the year for the first time, this being even more noticeable in the final quarter of 2016. Hence it follows that the behaviour of the system users and thus also the bookings of the transmission capacity is changing from long-term to extremely short-term bookings with increased instantaneous/extreme capacity requirements.

Transmission capacity at cross-border interconnection point Šempeter in 2016
By upgrading the transmission system, the TSO has in recent years been increasing the available capacity at cross-border interconnection points and addressing the most pressing problem of physical congestion in the transmission direction from Austria towards Slovenia at the cross-border interconnection point Ceršak. Figure 21 shows how the technical capacity and transmitted natural gas quantities ranged in the last six years at cross-border interconnection points. Over the past six years, in line with the progress made by the construction of a parallel pipeline M1/1 from Ceršak towards Rogatec and further with the construction of a parallel pipeline M2/1 from Rogatec towards Vodice, the TSO has gradually increased the technical capacity at the cross-border interconnection point Ceršak, which was followed by the booking of additional transmission capacity at this cross-border point by the system users.
In the year 2016, the transmission system users used all available interconnection points and directions for the physical cross-border transmission of natural gas. Moreover, the TSO notes that in the above- mentioned year, the largest daily transmitted quantities were mostly higher than in the previous year, while the highest monthly transmitted quantities were comparable. In the year 2016, the growing importance of the cross-border interconnection point Šempeter was noted, both for the consumption in Slovenia, as well as for the cross-border transmission. During certain periods of the year, an increase in the utilisation of the available capacity was recorded at this interconnection point. This was particularly notably expressed with the largest daily transmission in the direction from Slovenia towards Italy when the physical transmission was at the level of the technical output capacity of this interconnection point.

Physical transmission of natural gas towards Italy
The transmission of natural gas in the direction from Slovenia towards Italy was enabled in the beginning of 2015 after the completion of the investment cycle, which consisted of several projects: the construction of a compressor station in Ajdovščina, the construction of the parallel backbone of the transmission system from Ceršak to Vodice, the upgrade of the compressor station in Kidričevo with the third compressor unit, and the upgrade of the border metering and control station in Šempeter. Bi- directional transmission of natural gas between Slovenia and Italy at the interconnection point Šempeter/Gorica was established in accordance with the requirements of Regulation (EU) No. 994/2010 concerning measures to safeguard security of gas supply. With the aforementioned investment cycle, the transmission system was provided with additional cross-border capacities for the transmission of natural gas from Austria via Slovenia towards Croatia and Italy, in addition to the necessary facilities for supplying all domestic users from the eastern supply route via the Murfeld/Ceršak interconnection point.
With the introduction of transmission capacity booking via the auction platform PRISMA and with the implementation of a virtual point in Slovenia, we have noticed increased interest in cross-border transmission towards Italy. The amount of transmitted quantities and the frequency of cross-border transmission towards Italy show commercial interdependence of the gas markets of Austria, Slovenia, and Italy. In 2015 and 2016, the bookings of transmission capacity for transmission via Slovenia towards Italy on the auction platform PRISMA were mainly realised on a daily basis (the "day-ahead" service or "intra-day" service), and the transmitted quantities reflected the bookings. On 17 November 2016, the users have fully booked and used the available technical capacity of the interconnection Šempeter/Gorica for the transmission from Slovenia towards Italy for the first time. For the first time, the transmission system operated at the full capacity of the interconnection Šempeter/Gorica to transmit natural gas from Slovenia towards Italy (25.7GWh/day) for the entire day (24 hours). In addition to the operation of the compressor station in Ajdovščina, the two compressor units at the compressor station in Kidričevo had to operate simultaneously for the first time.
Depending on the way and the speed of the booking of transmission capacity on the booking platform PRISMA (intra-day booking) and the possible amounts of booking of transmission capacity by larger users, it can be concluded that such full booking of exit transmission capacity for the transmission from Slovenia towards Italy at the cross-border interconnection point Šempeter/Gorica can be repeated practically at any time.

Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
3.3.3 Booking forecast and estimates
Forecasts and estimates of transmission capacity booking are based on the available historical data, the envisaged upgrades of the transmission system in Slovenia and the region, the estimates of macro- economic indicators and the estimate of the increasing liquidity of the gas market. For the purposes of providing the estimate of the forecast of transmission capacity booking at the cross-border point, the transmission system operator maintains regular communication with its transmission system users at the cross-border points, which is ensured through regular personal contacts and meetings with the transmission system users.
The development of the Slovenian transmission system has been intense in the past period and we have achieved the adequate transmission capacity at all interconnection points. With the implementation of European legislation and adoption of new system operating instructions in 2015, we have additionally standardised and facilitated the bookings of transmission capacity and capacity allocation processes.
Table 15 presents an estimate of transmission capacity booking for the needs of cross-border natural gas transmission in the 2018 − 2021 period. In the case of capacity booking at interconnection points for domestic consumers, long-term contracts for the majority of total booked capacity will expire in 2017. When preparing forecasts for the booking of transmission capacity for the needs of cross-border transmission, the TSO takes into account the forecasts for booking at cross-border exit points. Due to the diversification of supply sources and the increase in liquidity of the gas market, the TSO finds that the conditions on the natural gas markets in the region have changed significantly, which further complicates the performance of the estimate of the forecast of transmission capacity booking over a longer period of time.
With the implementation of provisions of the Commission Regulation No. 984/2013/EU and the introduction of additional short-term transmission capacity products, including intra-day in 2015, the users have the option of booking transmission capacity for shorter periods, which is being increasingly utilised by them. The bookings presented in Table 15 are therefore only estimates, as the amount of transmission capacity booked at an individual relevant point varies on a daily basis. The presented estimates are prepared for the first day of the calendar year.

From 2015, the TSO provides slightly higher technical capacity at the cross-border interconnection points Ceršak and Rogatec than those provided by the neighbouring transmission system operators. The 31
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
TSO also provides the possibility of physical transmission of natural gas in the direction of Italy (Table 16).
With the additional capacity of the Slovenian transmission system, it is possible to supply the envisaged new domestic thermal power plants from the east supply direction, while any unused transmission capacity can be used for cross-border transmission of natural gas to Italy. To this end, by upgrading the border metering and control station Šempeter, the TSO also provided the possibility of bi-directional operations and exit transmission capacity at the cross-border interconnection point Šempeter (Table 15).
In the future, the TSO is planning further increases of transmission capacity at cross-border interconnection points, which will be achieved with the implementation of stage 2 of the extension of the compressor station in Kidričevo (project C5) and an upgrade of the compressor station in Ajdovščina (project C1). This will allow the TSO to meet the demand and further increase the transmission capacity at cross-border relevant points Ceršak and Šempeter after 2020. Table 16 only shows the development of technical capacity in the next 5-year period, since after this period, the capacity development of the Slovenian transmission system at cross-border interconnection points may already be significantly affected by the route of some of the new major pipeline projects in the region, whose capacities and time frames are not yet specified.

The TSO will implement the projects for increasing the available technical capacity of the natural gas transmission system in case of relevant requests and needs, and with the increase of capacity of neighbouring operators at cross-border interconnection points in agreement with the operators. This will ensure the consistency of construction of new capacities on both sides of cross-border interconnection points.

After this period, the capacity development of the Slovenian transmission system at cross-border interconnection points may already be significantly affected by the route of some of the new major pipeline projects in the region. In Table 16, the increased capacity 200 and timelines after the year 2020 are therefore provided according to the currently available information and data.

Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
The estimate of the operational security for an individual part of the transmission system is based on the flow-pressure calculation under the peak load conditions, which determines the load on the gas infrastructure and the exposure of users in case of failure of individual parts of the transmission system. The flow-pressure calculation checks the solutions (e.g., a system loop) to ensure a sufficiently powerful redundant transmission of natural gas to the exposed part of the transmission system.

4.1.1 "Management Centre" project
With the "Management Centre" project, we will increase the reliability of the operation of the natural gas transmission system, and ensure the long-term development and expansion of the functionality of the transmission system operator and the necessary information systems. As the most important object for managing the natural gas transmission system, the Management Centre will have to meet the high requirements of reliability and operational safety. Due to specific requirements, the Management Centre will be placed in a newly-built facility. In it, the flood risk of all the systems and subsystems necessary for the operation of the Centre and thus the technological management process will be completely eliminated.
The reliability of information systems in the Management Centre will be provided with an uninterrupted power supply system with great autonomy, and great attention will be devoted to the appropriate installation and protection of the technological equipment against the effects of electromagnetic interference, fire, and unauthorised access. The information system will consist of a process control system and a business information system, and with the use of standardised solutions, easier maintenance of systems and the implementation of upgrades of individual systems or related systems will be enabled.
The "Management Centre" project will provide the basic spatial framework, which can be further upgraded in the future, thus providing additional space for the potential expansion of the functionality of the Management Centre or the expansion of the transmission system operator's activity in the next long-term period. The information system will also have a redundant layout at a backup location, in accordance with the requirements of the legislation.
The company Plinovodi d.o.o. is in the stage of intensive development of new functions of information systems in accordance with the requirements of the legislation. For this reason, we continue with the automatisation and digitalisation of all business processes, as well as with the update of the process control system. With the "Management Centre" project, the following main functions of transmission process management and control, which are necessary for the management of processes, will be fully managed:
- Management of the transmission system with a Dispatch Centre; - Commercial management of transmission capacities and transmitted quantities by a Business Dispatch Centre; - Virtual point management with the virtual point organiser; - Management of the trading platform and other legally-defined information platforms; - Forecasting of the natural gas consumption in the function of the Forecaster.
With the content upgrade of information systems, we will simultaneously ensure efficient data exchange with system users and reporting in accordance with the legislation. For the realisation of the above functions, we perform the following activities:
1. Replacement of the process control system for the management of the transmission system The replacement of the management system is planned in the scope of exchange of hardware and system software in the Centre, as well as peripheral units for data acquisition and transfer. User interfaces for system overview and management will be upgraded in accordance with the latest technical guidelines and findings. 36
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
2. Implementation of the Forecaster Project and data exchange with the distribution system operators and suppliers The appointment of the company Plinovodi d.o.o. as the "Forecaster" is the central novelty of the Management Centre. After the preparation and adoption of the Methodology, the company started developing an application for forecasting using standard load profiles, as well as with the development of a data exchange system for data exchange with distribution system operators and suppliers.
3. Implementation of the EIC code system The company Plinovodi d.o.o. has the status of the local EIC code granter (Energy Identification Code) for Slovenia. The introduction of the standardised coding system EIC is a comprehensive project that will be linked to communication between systems within the Management Centre, as well as to external communication.
4. Standardisation of communication with users and transmission system operators The standardisation of communication will be based on the introduction of uniform and open standards for individual contents (e.g., AS4/Edigas for data exchange at interconnection points); moreover, the regulatory frameworks and the situation with other transmission system operators will also be taken into account
In the development of information systems, great attention will continue to be given to providing information security and further expanding the use of mobile applications.
Development of optical connections between the Management Centre and objects on the transmission system
In the field of communication technologies, the company Plinovodi d.o.o. started designing an optical connection between the Management Centre in Ljubljana and the significant facilities on the natural gas transmission system. On the basis of these projects, it will be possible to implement our own optical connections, thus ensuring greater transmission capacity of process data from individual locations on the transmission system, and in addition, preventive monitoring of potential interventions in the vicinity of the transmission pipelines will be possible with the use of modern technologies. In the first phase, the optical connection between the Management Centre and the metering and regulation station in Ljubljana, and then to the optical hub at the metering and regulation station in Vodice will be performed.
Development and upgrading of functionality within the Management Centre
Within the framework of the "Management Centre" project, the company Plinovodi d.o.o. will, as the transmission system operator, provide all the necessary information support for the " Unit for Natural Gas Quality Monitoring and Evaluating", as well as for the "Unit for Metering System Control for Measuring Transmitted Natural Gas Quantities". An increasingly dynamic natural gas market requires quality measurements, and the expected flows of natural gas from multiple sources require a systematic monitoring of the composition and quality of gas.
1. Unit for Natural Gar Quality Monitoring and Evaluating
On the basis of the standard on the quality of natural gas EN 16726:2016 and the system operating instructions SON:2015, the parameters of the natural gas quality at the entry, exit, and selected internal measuring points of the Slovenian transmission system must be measured continuously and cyclically. For the monitoring of the quality of natural gas, data and signals from stationary and portable metering systems or meters, such as chromatographs, water and hydrocarbon dewpoint meters, molar concentration meters, e.g. oxygen, carbon dioxide,
37
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
nitrogen, were going to be transmitted. The parameters for the quality of natural gas must be measured using modern criteria and measurement methods recognised in the European Union.
The tasks of the Unit for Natural Gas Quality Monitoring and Evaluating are maintenance and calibration of measuring systems or meters for measuring the quality of natural gas, as well as the measuring, evaluation and taking the necessary actions.
2. Unit for Metering System Control for Measuring Transmitted Natural Gas Quantities
The Unit for Metering System Control must continuously monitor the functioning of the installed gas meters and correctors at the measuring points, as well as control the data transfer from the meters to the Centre. On the basis of data on the quality of natural gas, the transmitted energy quantities are also checked in the Centre on the basis of the valid standards and recommendations.
It is necessary to provide a comparative measurement of the transmitted volumes of natural gas at the entry and exit measuring points on the transmission system. The data must be compared with the data from the neighbouring transmission system operators. When evaluating the benchmark measurements, the criteria and statistical estimators, used in the research work, must be used. The task of the Unit is also data verification in the data transmission systems Telereading and Validation. Based on the findings in the data verification process, it is necessary to keep the relevant departments and units in the company Plinovodi d.o.o. updated.
4.2 Connection projects
Figure 24. Locations of projects for new connections 38
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
The connections group includes projects for connections of new consumers, changes to the operational characteristics at pipeline structures for existing consumers, and the connection of a natural gas producer. These have been included in the list based on queries, connection approvals and/or connection contracts. Connection projects also include projects for connection of users establishing an infrastructure of CNG filling stations − compressed natural gas for powering vehicles.
The aforementioned projects also include the connection of a natural gas producer to the transmission pipeline system in the region of Pomurje. The producer is the holder of concession rights for the extraction of mineral resources, crude oil, natural gas and gas condensate in the area of the Mura Depression, i.e. in the gas and oil fields Dolina and Petišovci pri Lendavi.
In table 19, all connection projects are presented (also included in Tables 7, 8, 9, and 10), both those for which interest has been shown, as well as those identified by the transmission system operator as having potential on the basis of their own analyses, for which interest for connection has not yet been expressed by the existing or potential users.

Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
4.3 Development of interconnection points with the neighbouring transmission systems
The projects of development of interconnection points (interconnections) with the neighbouring transmission systems are aimed at establishing new interconnection points with the neighbouring systems, increasing the existing transmission capacities, establishing reverse flows, and meeting the infrastructure standard N-1.
For better information and overview of these projects, we exchange consultation forms with detailed information on relevant planned projects with the neighbouring TSO each year as part of the preparation of development plans, as well as attend various public debates, consultations and coordination meetings.
A project linking the Slovenian and Hungarian transmission systems managed by the FGSZ Ltd has the status of a "Project of Common Interest" (PCI) in line with the Regulation 347/2013/EU and is included in the list of Commissioned Delegated Regulation (EU) 2016/89 of 18 November 2015. The project envisages construction of a 73km pipeline and expansion of the existing compressor station Kidričevo with additional compressor units. The purpose of this project, shown in Figure 25, is to connect the so- far unconnected Slovenian and Hungarian transmission systems, provide Slovenian suppliers access to Hungarian underground storage facilities, and provide Hungarian suppliers access to western gas markets and LNG sources in Italy and North Adriatic. The project also improves the infrastructure standard N-1 and is a candidate for the next PCI list, which will be confirmed at the end of 2017.
Figure 25. PCI project 6.23 Interconnection Hungary − Slovenia
In accordance with the above legislation, a group of projects in the corridor of Austria, via Slovenia, towards Croatia have a status of a project of special interest. This is an upgrade of the capacity of existing transmission systems and the establishment of reverse flows between the systems that are managed by us and in addition to us also by the companies Gas Connect Austria GmbH and Plinacro d.o.o. Figure 26 shows the harmonised technical parameters and the time line of the project
41
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period implementation. In the Slovenian system, this project envisages the following: the reconstruction of the interconnection Rogatec, the reconstruction of the interconnection Ceršak, and the extension of the compressor station Kidričevo. These projects are candidates for the PCI status in 2017, as well.
Figure 26. PCI project 6.26 Interconnection of Croatia, Slovenia and Austria at Rogatec
The interconnection hub in eastern Slovenia is CS Kidričevo. The further development of this point is designed to cover larger or smaller requirements for additional operating capacities in the direction of Austria, Croatia and also Hungary via the planned pipeline R15/1.
Due to the strengthening of the regional gas market and the establishment of the southern gas corridor, whose projects will bring natural gas and liquefied natural gas to the region, the strengthening of the connection of the Slovenian system with the Italian transmission system in Gorizia is becoming more and more important. According to the realisation of the development plan prepared by Snam Rete Gas S.p.A. for the period from 2016 to 2025 and the new development plan for the period from 2017 to 2026, which is under preparation, upgraded bi-directional connections in the direction of the north of the Union and the east of the Union will be established in the northern part of Italy after 2018. In 2019, they will already be able to operate technically, which means that the Slovenian system will have to adapt to the newly created pressure conditions in the Italian system due to bi-directional operation.
In order to provide a reverse flow in the direction of Gorizia in larger capacities, the following projects should be carried out on the transmission system:
The first stage of the expansion of CS Ajdovščina (project C1), i.e., an additional compressor unit at CS Ajdovščina; and The reconstruction of the pipeline M3 and the branches between the CS Ajdovščina and the cross-border point in Nova Gorica, together with the new cross-border station Nova Gorica (project C2).
In case of market demands for a significant increase in capacity at the entry/exit point Nova Gorica, the second stage of the extension project of the CS Ajdovščina will have to be realised and the pipeline interconnection M3/1 from Vodice to Nova Gorica implemented.
42
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
The construction of the pipeline M6, which will supply the Obalno-kraška region, run from Ajdovščina to Lucija, and in its course approach the national border with the Republic of Italy, will enable the implementation of another additional interconnection of the Italian and Slovenian transmission networks at Osp. This means that the project M6 provides a new interconnection, which is also included in the Snam Rete Gas S.p.A. development plan for the period from 2016 to 2025 and the new development plan for the period from 2017 to 2026.
Figure 27. Upgrade of the interconnection Slovenia − Italy and potential new interconnection with Italy at Osp
We are also planning a new interconnection with the Croatian transmission system. The construction of a 60-km pipeline M8 Jelšane − Kalce that will provide the transmission of natural gas from the possible LNG terminal on the Island of Krk in Croatia and/or the possible IAP transmission system (Ionian Adriatic Pipeline) is planned. Also related to the project of transporting Croatian LNG through Slovenian territory is the construction project for the 100-km pipeline M3/1 Šempeter − Vodice; in addition to providing transmission to the Italian transmission system, the pipeline will also provide transmission of the same gas to the extended interconnection point Ceršak and onwards to the Austrian system.

4.4 Projects in preparation and planning in the 2018 − 2020 period and projects in implementation The TSO estimates to have a total of 27 projects in preparation and planning in the 2018 − 2020 period and to carry out (construct or begin construction on) 18 of those projects, while 8 will remain in planning with envisaged investments in studies, location and investment documentation in the next 3 years. Although the majority of the projects did not have a FID status as of 1 January 2017, the TSO estimates that they have achieved suitable maturity in respect to the level of treatment achieved on both sides, i.e. on the part of the TSO and on the part of the potential transmission system users.

4.5 Assessment of options for the increase of energy efficiency
In accordance with Article 30 of the Energy Act (EZ-1), the development plan must include an assessment of the potential for the increase of energy efficiency of gas and electricity infrastructure by means of load balancing and interoperability, connection with energy production plants, including microproduction, and define time dynamics and financial evaluation of planned investments and actual measures for cost-effective improvements in the network infrastructure. The company Plinovodi performs the following activities in the following areas:
1. Load balancing and interoperability of the transmission system
In order to provide sufficient capacity for the required transmission system load and its interoperability with the neighbouring transmission systems, the company Plinovodi ensures coordinated development of the transmission system and interconnection points with the neighbouring transmission systems. At the end of 2014, the company Plinovodi completed a large-scale upgrade investment cycle, by which it provided additional urgently needed transmission capacity and substantially improved the operating characteristics of the transmission system. In the sense of ensuring energy efficiency, the company Plinovodi devotes a lot of attention to the regime of compressor station operation and the balancing of the transmission system, where both the number of operating hours and the operating settings of the compressor units are optimised in order to adequately load the transmission system and meet the conditions at the interconnection points with the neighbouring transmission systems. The successfully completed investment cycle, which provided the required transmission capacity and enabled the 47
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period further development of the transmission system, within the meaning of Article 15 of the Energy Efficiency Regulation, represents a very important contribution to increasing the efficiency of gas infrastructure.
After the upgrade, the transmission system can, from the perspective of ensuring interoperability, enable the handling of transmission capacities according to the model of entry-exit points, where users can independently book the entry and exit capacities. Due to the upgrade, there are no more internal bottlenecks on the main trunk gas pipelines, and gas can be transmitted from one entry point practically to any exit point, which is an essential contribution in terms of ensuring the interoperability of the transmission system. The independent treatment of transmission capacity at entry and exit points has enabled the introduction of a virtual point of natural gas trading, which represents an additional contribution to the effectiveness of balancing the deviations between the takeover and delivery of natural gas to the holders of balance groups, and to ensuring the balance of the transmission system. The company Plinovodi has established a virtual point of natural gas trading and has been its operator since 2015. In order to improve the interoperability of the transmission system and the infrastructure standard for ensuring a secure supply of natural gas, the company Plinovodi will provide the possibility of bi-directional operation at the interconnection point with the Croatian transmission system in Rogatec in the following years. The connection between the Slovenian and Hungarian transmission systems will also contribute to increased interoperability of the Slovenian gas infrastructure, which is being planned by both neighbouring transmission system operators in several phases, taking into account the gradual increase in transmission capacity.
2. Connection with energy production plants, including microproduction
In order to increase the energy efficiency of the transmission system, the company Plinovodi joined the modernisation of heating systems for natural gas, where the innovation for the contribution to reducing its own consumption of natural gas was also approved in the company in 2016. Thus, with the implementation of a heating system modification on five metering and regulation stations based on the analysis of own use for the heating of natural gas, the annual average natural gas savings was 3 estimated at 16,250Sm , which corresponds to the emission of 30.5 tonnes of CO2 per year. The company Plinovodi will continue with the modernisation of heating systems in other metering and regulation stations, thus increasing the energy efficiency of the natural gas transmission system.
In terms of ensuring energy efficiency, the company Plinovodi took advantage of the possibility of using the existing electrical equipment on the natural gas transmission system in connection with the electricity network within the system for tertiary frequency control, with the consumption management and dispersed production of electricity. The upgrade of the electrical equipment at the compressor station and the signing of the contract with the power generator enable the remote start of the backup diesel generator, which supplies the contracted amount of electricity for the needs of tertiary frequency control to the transmission power line. The company Plinovodi has already started with the preparation of an additional diesel generator for integration into the tertiary frequency control system.
In order to increase energy efficiency, the company Plinovodi has also decided to build a small, 69.9kW photovoltaic power plant at the company's headquarters in Ljubljana. The produced electricity is transferred to the network of the distribution system operator and will in the coming years represent a contribution to the energy efficiency, as well.
48
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
In the context of microproduction, connections of biomethane production devices to distribution networks or natural gas transmission systems on gas networks in Western Europe are expanding. The company Plinovodi monitors the intensity of the connection of biomethane production devices in Europe and supports the first project that is being prepared in Slovenia.
3. Investments and actual measures for cost-effective improvements in the network infrastructure
In the company Plinovodi, energy efficiency is monitored by tracking environmental indicators within the framework of the established Environmental Management System according to the ISO 14001 standard. In addition to the comprehensive management of the environmental aspects of Plinovodi's activities, the system also includes cost control and efficient use of resources. Environmental indicators are set up to express the environmental and economic performance of business processes as clearly as possible. The measures for cost-effective improvements are linked to regular periodic evaluation of the following environmental indicators in the company Plinovodi: consumption of natural gas for own use, and cooling and heating of business premises, flue gas emissions, noise emissions, water consumption, electricity consumption and generation, heat energy consumption, fuel consumption, flue gas quantity, carbon footprint of the company, and the amount of disposed waste.

5 European dimension of natural gas supply
In 2015, the European Commission took an integral approach to energy policy. Within the context of the Energy Union Package, it published the Framework Strategy for a Resilient Energy Union with a Forward-Looking Climate Change Policy (COM(2015) 80 final), declaring 5 key dimensions of operation: Energy security, solidarity and trust; A fully-integrated internal energy market; Energy efficiency as a contribution to the moderation of energy demand; Decarbonisation of the economy; and An energy union for research, innovation and competitiveness.
At the end of 2015, the European Commission published the first report on the state of the Energy Union (COM(2015) 572 final). Among other things, the report stresses the importance of the energy infrastructure for the operation of the integrated internal energy market. In this regard, the importance lies in connections between Member States to provide access to energy from various sources and routes. Suitable infrastructure connections are also essential for ensuring adequate energy security. The European Commission urges the Member States to devote special attention to the projects of common interest specified in the second list of projects of common interest. Furthermore, the Commission also points out the need to improve the integration of national natural gas markets on a regional level.
5.1 Development of exchanges with other countries After four consecutive years of decline in natural gas consumption in Europe, the latest Eurogas11 estimates specify a 7% increase in natural gas consumption in the EU in 2015 compared to 2014. Particularly in the first half of 2015, consumption was 9% higher than in the same period of the previous year.
The increase in demand for natural gas can mainly be attributed to the seasonal and annual variable weather conditions. The last two years have been unusually warm (2014 was a record warm year for certain EU countries), while 2015 was close to the average. Considering the changing weather conditions, natural gas is particularly relevant for heating and cooling, since it has the capacity to provide high and varying amounts of energy in households.
In addition to climate conditions, the higher consumption of natural gas was also influenced by other factors, e.g. when hydroelectric energy production decreased in Germany and Italy natural gas filled the gap in the energy supply.
The demand for natural gas for the production of electricity has increased in some of the EU countries (e.g. France with increased demand in industry and Austria with increased use of CHP/cogeneration), but low coal prices continued to have significant impact on the demand for natural gas. With the recovery of the European economy, there was a slight increase in demand for gas in the industrial sector.
The forecasts of natural gas consumption until 2050, based on the political commitments of the European Council of October 201412 and defining the transition to a low-carbon society, are optimistic

Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period in respect to the 2020 − 2035 period13. The adopted commitments set out a 40% reduction in greenhouse gas emissions in the EU from 2020 to 2030. According to these commitments, the consumption of natural gas will gradually decrease in the future, with its share in the balance sheet of all consumed energy dropping from 25% in 2010 to 22% in 2030 and 18% in 2050.
5.2 Supply of natural gas to EU countries and access to natural gas sources
More than half of the energy for the supply of EU countries is imported. The EU countries are dependent on imports of crude oil (nearly 90%) and natural gas (66%) and to a lesser extent solid fuels (42%) and nuclear fuels (40%). In relation to the security of energy supply, the issue of strong dependence of certain countries on a single external supplier remains. This is particularly problematic where natural gas and electric energy are concerned. As many as 6 Member States in the EU depend on Russia as the sole supplier of the entire gas import volume and in three of these countries natural gas accounts for more than one quarter of their total energy needs. In the year 2013, the energy supply from Russia represented 39% of the natural gas imports in the EU or 27% of the gas consumption in the EU. Russia has exported 71% of its gas to Europe, most of it to Germany and Italy. The security of energy supply to the EU must be addressed within the increasing demand for energy worldwide. This demand is supposed to increase by 27% in the next 15 years, which will result in substantial changes regarding energy supply and trade flows. (Source: European strategy for the security of energy supply14)
In the past period, especially in the year 2014, the natural gas market was characterised by concern about potential interruptions of Russian natural gas supply, particularly through Ukraine. The European Council of March 2014 called the European Commission to conduct an in-depth study on energy security and to present a plan on how to reduce the energy dependence15, as the EU imports nearly 70% of the natural gas it requires. This imported share is estimated to remain the same until 2020, increasing somewhat after this period and reaching between 3,800 and 4,000TWh from 2025 to 2030. In the year 2013, 39% of gas was imported from the Russian Federation, 33% from Norway and 22% from North Africa (Algeria, Libya). Other sources are minor, reaching approximately 4%. The imports of liquefied natural gas have even reached 22% of all gas consumed in 2010, but dropping back to 15% due to lower prices on the Asia-Pacific gas market. We estimate that the role of liquefied natural gas as the main potential source for diversification will be maintained if not increased in the following years. The new supply of liquefied natural gas from North America, Australia, Qatar and new sites in East Africa will likely increase the size and liquidity of global liquefied natural gas markets. Among other projects of this type, the first liquefication plant on the East Coast of the United States should be mentioned. Its planned start of operations is between 2015 and 2017, and its planned capacity is approximately 270TWh/year. The possibilities for increased production can also be found in Norway (up to 1,300TWh/year in 2018 from the current 1,200TWh/year) and North Africa, as well as the Mediterranean region (potentially large volumes of unexplored or untapped hydrocarbon resources and the advantage of geographical proximity).

5.3 REGULATION (EU) No. 347/2013 on guidelines for trans-European energy infrastructure With the Regulation (EU) No. 347/2013, the European Commission has set out the priority corridors and areas important for the development of an integrated energy network. The Regulation affects the fields of spatial planning, environmental impact assessments (cross-border included) and public consultation procedures. It also provides the so-called priority corridors and criteria for designating Projects of Common Interest (PCI). The Regulation defines priority corridors and areas of trans- European energy network infrastructure. The Republic of Slovenia and its gas infrastructure is ranked in this Regulation under the following two priority corridors:
North-South gas interconnections in Central Eastern and South-eastern Europe ("NSI East Gas"): regional gas interconnections between the Baltic Sea region, the Adriatic and Aegean Seas and the Black Sea for extension and enhanced security of gas supply routes. Member States concerned are: Austria, Bulgaria, Cyprus, Czech Republic, Germany, Greece, Hungary, Italy, Poland, Romania, Slovakia and Slovenia;
52
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
Southern Gas Corridor ("SGC"): transmission of gas from the Caspian Basin, Central Asia, the Middle East and Eastern Mediterranean Basin to the EU to enhance diversification of gas supply. Member States concerned are: Austria, Bulgaria, Czech Republic, Cyprus, France, Germany, Hungary, Greece, Italy, Poland, Romania, Slovakia and Slovenia.
5.3.1 PCI 2015 list
On 18 November 2015, the European Commission adopted the second list of 195 key energy infrastructure PCI projects (Projects of Common Interest) that will make it easier for Europe to achieve the energy and climate goals (C(2015) 8052 final). The PCI 2015 list comprises 108 projects in the field of electricity, 77 in the field of gas, 7 in the field of oil and 3 projects in the field of smart networks. The balance between projects in the field of electricity and gas was also achieved due to a clear definition of priority projects in the regional context.
The projects, defined as the Projects of Common Interest, are subject to certain advantages: Enhanced transparency and public consultation; Simplified authorisation procedures (the binding time limit is three and a half years); Better, quicker and simplified environmental assessment; S single national authority operating as a "one-stop" point for authorisation procedures; Improved regulatory treatment with allocation of costs based on net benefit and regulatory incentives; Possibility of financial aid under the Connecting Europe Facility (CEF) in the form of grants and innovative financial instruments.
In order for a project to be included in the PCI list, it must be proven that the project brings significant benefits for at least two Member States. In addition, it must contribute to market integration and enhance competition, as well as increase the security of energy supply and reduce carbon dioxide emissions.
Table 23. List of projects included in the PCI 2015 list # Project PCI 2015 C3 R15/1 Pince − Lendava − Kidričevo X
C12 Upgrade of interconnection Rogatec X
C4 Upgrade of interconnection Ceršak X
C5 CS Kidričevo − extension stage 2 X
The above projects are included in the PCI 2015 list in the context of two project groups, namely:
6.23 Interconnection Hungary − Slovenia (Nagykanizsa − Tornyiszentmiklós (HU) − Lendava (SI) − Kidričevo) 6.26 The group Croatia − Slovenia − Austria via Rogatec, which includes the following projects: 6.26.1 Interconnection Croatia − Slovenia (Lučko − Zabok − Rogatec) (CRO) 6.26.2 CS Kidričevo, extension stage 2 (SI) 6.26.3 Compressor stations on the Croatian gas transmission system (CRO) 6.26.4 GCA 2014/04 Murfeld (AT)

6.26.5 Upgrade of interconnection Ceršak/Murfeld (SI) 6.26.6 Upgrade of interconnection Rogatec (SI)
The second list (PCI 2015) of key energy infrastructure projects is valid until the end of 2017, and in cooperation with the Member States, the European Commission has already begun with the procedures for defining key energy infrastructure projects that will be placed on the third list of key energy infrastructure projects. The new list will be published at the end of 2017 and will be valid in 2018 and 2019. In the phase of applying the candidates for the Projects of Common Interest, the company Plinovodi has applied to the European Commission the projects within the existing PCI 6.23 interconnections Hungary — Slovenia (Nagykanizsa — Tornyiszentmiklós (HU) — Lendava (SI) — Kidričevo) and 6.26 group of projects on the corridor Croatia — Slovenia — Austria via Rogatec.

5.4 ENTSOG
The establishment of the European Network of Transmission System Operators for Gas (ENTSOG) was provided for by Regulation No. 715/2009/EC. ENTSOG was founded on 1 December 2009 with the objective of accomplishing the following tasks: to facilitate the formation and operations of a single European internal market and cross-border trading in natural gas, as well as to ensure optimal management, coordinated operation and technical evolution of the European natural gas transmission system by preparing and proposing adequate network codes.
The company Plinovodi is one of the founding members of ENTSOG. Its current membership structure is: 45 European TSOs and 2 associated partners (from Member States that are currently still operating
54
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period under the suspension of the requirements deriving from Regulation No. 715/2009) from 26 EU Member States and 4 observers from Europe (Norway, Switzerland, Ukraine, Macedonia).
The central task of ENTSOG is to prepare network codes, the EU ten-year development plan, the "Winter Outlook" and "Summer Outlook" reports, to inform the interested public, bring together TSOs and cooperate in the preparation of 3-year regional investments plans within the EU.
Figure 32. ENTSOG members
5.4.1 TYNDP
One of the central objectives of the TYNDP (Ten Year Network Development Plan) is to provide an overview of trans-European infrastructure, thereby detecting potential gaps in future investments. The European 10-year development plan aims to cover a wider dynamics of the European gas market in relation to supply potential, market integration and security of supply. 55
Ten-Year Gas Transmission Network Development Plan for the 2018 - 2027 Period
ENTSOG publishes the 10-year development plans on its website: http://www.entsog.eu/publications/tyndp. In accordance with the requirements of Regulation (EC) No. 715/2009, the TYNDP is prepared every two years.
When preparing the European TYNDP, the company Plinovodi has been cooperating with ENTSOG since the preparation of the first plan in 2010. Thus, the projects of the Slovenian TSO are summarised in the European TYNDP and coordinated with the national 10-year development plans. The TSO guarantees that the European TYNDP includes all projects that are listed in the national 10-year development plan and that can be qualified as affecting the European gas infrastructure. When preparing the national 10-year development plan, the TSO always ensures that the forecasts of estimated transmitted quantities and booked transmission capacities are coordinated. With the coordination of the development plans, the transparency and impartiality in development of gas transmission infrastructure can therefore be assured.
The basis for registering projects in the ENTSOG TYNDP is their involvement in the national development plan. As a rule, we apply projects of international significance that interconnect with the neighbouring transmission systems in the TYNDP. In Annex 2 Planned transmission infrastructure, there are the project codes from the ENTSOG TYNDP entered in the assembly tables, which show which projects are included in both development plans and under what code.
In the beginning of 2016, the preparation of the 5th edition of the European Ten-Year Network Development Plan (TYNDP) for a period of 20 years (2017−2037) has begun. A 6-week public consultation was held from 10 December 2016 and 2 February 2017. After reading all the remarks and comments received, the document was officially published on the ENTSOG website at the end of April 2017.
5.4.2 GRIP CEE and GRIP Southern Corridor
In accordance with the requirement for the promotion and establishment of regional cooperation as laid down in Directive 2009/73/EC OF THE EUROPEAN PARLIAMENT AND THE COUNCIL of 13 July 2009 concerning common rules for the internal market in natural gas and repealing Directive 2003/55/EC (Article 7) and Regulation (EC) No. 715/2009 OF THE EUROPEAN PARLIAMENT AND THE COUNCIL of 13 July 2009 on conditions for access to the natural gas transmission networks and repealing Regulation (EC) No 1775/2005 (Article 12), the TSOs within ENTSOG publish a Gas Regional Investment Plan (GRIP) every two years, which forms the basis for the adoption of decisions regarding investment.
As the Slovenian TSO, the company Plinovodi takes part in the preparation of two GRIP documents, namely GRIP Southern Corridor and GRIP Central Eastern Europe (CEE). GRIP Southern Corridor is prepared in cooperation with TSOs from Greece, Italy, Austria, Bulgaria, Croatia, Hungary, Romania, Slovakia and Slovenia, and GRIP Central Eastern Europe is prepared in cooperation with operators from Austria, Germany, Croatia, Bulgaria, Hungary, Poland, Romania, Slovakia and Slovenia.
The preparation of new GRIP documents for the 2017 – 2026 period began in mid-2016. GRIP CEE was completed and published in August 2017, and GRIP Southern Corridor in September 2017.
