PREFACE

This Distribution System Capability Statement (DSCS) is provided by Muscat Electricity Distribution Company (MEDC) to fulfil its regulatory obligations under Condition number 32 of the MEDC Distribution and Supply Licence as well as the Oman Distribution Planning Code 4.4.

MEDC supplies electricity to customers throughout the Muscat Governate as the owner and operator of its electricity distribution system originating from the 33kV busbars of the Oman Electricity Transmission Company (OETC) 132/33kV grid substations down to the final customer’s point of connection; which incorporates 33kV, 11kV and Low Voltage (LV) distribution system voltage levels and associated assets.

The aim of this DSCS is to provide an up-to-date distribution system capability for the next three years (2021-2023) along with data to enable customers in identifying parts of the system; which offer opportunities for future connections or upgrading of existing connections to the MEDC system and where constraints currently exist or potentially could exist in future.

In addition to the required data made available annually as part of DSCS; MEDC additionally has provided improved detailed system connectivity and additional technical data of assets, impact analysis of Cost Reflective Tariff (CRT) on MEDC customers and an overview of the photovoltaic (PV) system penetration in the MEDC distribution system which is gaining momentum in our licenced area as well. These additions are expected to provide customers and other stakeholders with a transparent understanding of MEDC distribution system and operational overview, sufficient technical parameters to undertake initial system capabilities assessment and the overall distribution system development. Additionally, this year the world including MEDC customers and hence its network have experienced a force-majure event triggered due to the COVID-19 pandemic which has temporarily but significantly impacted electricity demand including future growth in the MEDC licenced area.

MEDC have determined this three-year plan to clarify and highlight MEDC’s key priorities over the DSCS planning period. The plan will form the basis for the company’s investments to provide economic and efficient system development along with serving to inform MEDC’s contributions to the Oman electricity sector.

MEDC Distribution System Capability Statement (2021-2023) – V2.0

1. INTRODUCTION

1.1. Purpose of the Statement The information in the Distribution System Capability Statement (DSCS) is published annually to fulfil MEDC regulatory obligation under Condition 32 of its Distribution and Supply Licence (D&SL) and Distribution planning code 4.4 of the Oman Distribution Code.

This DSCS is intended to provide an understanding of MEDC’s 33kV, 11kV and LV distribution system along with presenting MEDC’s development plans for the 33kV and 11kV distribution system for the years 2021-2023. This statement includes power system data for the station loads, overhead lines, cable circuits, transformers, switchgear and capacitors which forms the MEDC distribution system and used in the preparation of distribution system models for the power system studies. The results of load flow, short circuit studies and system technical losses are presented thereby providing an assessment of the capability of the distribution system.

Implementation of the system development plans is necessary to meet future forecast demand growth, maintain and/or improve the capability in the distribution system to meet the system growth and to address the issues of actual or forecast non-compliance with the Distribution System Security Standard (DSSS). Implementation of these plans will enhance the available system capacity as well as potentially increase the number of 33/11.5kV primary substations (PSS) providing enhanced opportunities for new and increased customer connections.

The impact of MEDC’s forecast demand growth and distribution system development plans on the Transmission System, which is owned and operated by Oman Electricity Transmission Company (OETC), has been fully assessed in the development of MEDC’s development plans. Where appropriate 33kV load transfers from one 132/33kV grid substation (GSS) to another are feasible they have been considered and where this option is not feasible; applications for additional 132/33kV GSS capacity have been submitted to OETC, resulting in OETC plans to construct and build additional 132/33kV GSS capacity within the MEDC licence area.

1.2. Structure of this DSCS

The following summarises the structure of this Distribution System Capability Statement:

• Chapter 2 and Chapter 3 provide relevant information associated with MEDC’s licence obligations, technical standards and system planning drivers along with distribution system connectivity. • Chapter 4 provides a summary view of the distribution system, together with details of the 2020 demand profile along with projected demand forecast, CRT impact analysis of MEDC system, system constraints, update on continuous improvement areas on the system for the DSCS, template of the complete system asset data published this year and a summary of the required technical power system analysis of the distribution system. • Chapter 5 summarises the current levels of connection activity within the MEDC system and provides an overview of the opportunities/challenges new customers potentially could face whilst identifying the challenges that MEDC face currently along with measures to address them.

MEDC Distribution System Capability Statement (2021-2023) – V2.0 2

2. P L A N N I N G PHILOSOP H IES AND PRACTICES

MEDC recognise that it is fundamental to provide sufficient guidance to enable relevant stakeholders along with current and potential customers to understand the quality of supply that they may receive from the distribution system; also to enable any person seeking a connection to the system to be able to understand the distribution system at the intended point of connection.

The DSCS below briefly identifies relevant conditions of the Sector Law and the associated Planning Codes and Security Standards that MEDC as a regulated entity must adhere to. It further outlines the key technical standards to which MEDC distribution system is designed and constructed to.

Royal Decree 78/2004 promulgated the Law for the Regulation and Privatisation of the Electricity and Related Water Sector. Article 90 of the D&SL places an obligation on Distribution Companies to undertake financing, operation, maintenance, development and expansion of the distribution system in a safe, economic and efficient manner and in accordance with the relevant performance and security standards.

2.1. Obligations of the Distribution and Supply Licence (D&SL) Condition 4 of MEDC Distribution Licence as entitled ‘Implementation of and Compliance with the Distribution Code’; requires MEDC to become and remain a party to and comply with the provisions of the Distribution Code. It also requires MEDC to co-operate with other Licensed System operators in the maintenance and development of the Distribution Code.

Distribution Licence Condition 32 is titled ‘Distribution System Capability Statement’ and requires MEDC to:

‘On an annual basis, prepare a statement in a form approved by the Authority, showing in respect of each of the three succeeding financial years, circuit capacity, forecast power flows and loading on each part of its Distribution System and fault levels for each transmission node.’

Licence Condition 32 also describes further information that needs to be included within the DSCS relating to:

• Information on the status of the Distribution System, its capacity and envisaged future needs. • Advising potential customers on parts of the system that are best suited to new connections. • Information on the potential system constraints to development. • Provide an overview of current system developments. • Assessment of technical losses.

The full requirements of Licence Condition 32 are found in Appendix A of this document.

The intent of this DSCS is to provide the information as stated above in a form that is relevant and useful to its customers; Authority for Public Services Regulation (APSR) and other stakeholders.

MEDC Distribution System Capability Statement (2021-2023) – V2.0 3

2.2. Requirements of the Distribution Code The Distribution Code covers all material technical aspects relating to connections to, and the operation and use of, the distribution system. The Distribution Code is structured into a number of specific sections.

The Distribution Planning Code (DPC) 2 states that its objectives include for:

‘the exchange of information and interaction between Licensed Distributors and Distribution System Users concerning any proposed development of Distribution System User Systems that are to be connected to the Distribution System’.

DPC 4.4 relates to the obligations of MEDC under its Distribution Licence to produce, on an annual basis, the Distribution System Capability Statement relating to the three succeeding years.

2.3. Distribution System Security Standard As part of maintaining an adequate electricity supply to our consumers; MEDC is obliged under its distribution licence to:

‘plan and develop its Distribution System in accordance with the approved Distribution System Security Standard’1 and to ‘operate and maintain a safe, efficient and economic Distribution System in accordance with the Security Standards’2.

Table 1 provides a summary of the DSSS classifications.

Table 1 : DSSS Classifications and Defined Restoration Times

Class Demand Group First Outage Second Outage

A Less than 2 MW Repair Time No Requirement

B 2MW to 6MW 3 Hours* No Requirement

C 6MW to 20MW Within 15 minutes Restoration time of planned outage

D 20MW to 100MW Immediately Restoration time of planned outage

E Greater than 100MW Immediately Immediately, 2/3 of demand**

*For 11kV networks in remote areas this restoration time may be extended by the time it reasonably takes for a repair crew to reach the area with the outage as long as the total restoration time will not exceed 6 hours

**Planned Outages area assumed to be restricted to non-summer periods when due to lower ambient temperatures demand is reduced and equipment ratings enhanced

The DSSS places an obligation on MEDC to restore supply following a circuit or transformer outage within maximum time limits determined by the total demand within a Demand Group as highlighted in Table 1.

1 Licence Condition 31 (4a) 2 Licence Condition 31 (4a) and (4b)

MEDC Distribution System Capability Statement (2021-2023) – V2.0 4

A first outage is a fault or planned outage occurring at any time of the year including the period of maximum demand. A second outage is a fault outage occurring when an integral part of the system under consideration is not available due to planned maintenance.

The MEDC 33kV system and 33/11.5kV primary substations fall into DSSS classes B to D with the majority being in Class C.

Primary substations in Class B have a maximum demand between 2MW and 6MW. Following a first outage the affected load must be re-supplied within 3 hours. This may be achieved by repair and restoration of the faulted circuit, manual switching at the 33/11.5kV primary substation with two or more transformers to re-supply customers from an alternative transformer or manual switching of the 11kV network feeders to re-supply customers from an alternative 33/11.5kV primary substation.

Substations in Class C have a maximum demand between 6MW and 20MW. Following a first outage the affected load must be re-supplied within 15 minutes. This is achieved by the system configuration and operational control, operating with parallel circuits and remotely operating the circuit breakers from the MEDC Distribution Control Centre via SCADA.

The majority of existing MEDC 33/11.5kV primary substations have 2 x 20 MVA transformers with a N-1 firm capacity of 20MVA. These substations fall into the DSSS Class C classification.

33/11.5kV primary substations in Class D have a maximum demand between 20MW and 100MW. Following a first outage, the affected load must be re-supplied immediately. Immediate restoration means allowing an adequate time for an interruption followed by restoration through an automated transfer switching scheme with restoration effected typically within 60 seconds and upto 3 minutes. Typically, all new primaries constructed are 33/11.5kV primary substations with 3x20MVA transformers which fall into the Class D classification.

2.4. System Voltage Levels and Configuration Distribution Connection Conditions Code (DCC) 4.1 states the following:

The voltage on the 33kV,11kV and LV sides of distribution transformers at connection sites with distribution system users shall normally be controlled within the limits of ± 6.0% of the nominal voltage.

The voltage at customer’s terminals shall not vary from the system nominal voltage +/- allowed tolerances as shown in Table 2.

Table 2 : System Nominal Voltages and Tolerance

Nominal Voltage Tolerance Level +6% -6% 33kV 34.98kV 31.02kV 11kV 11.66kV 10.34kV 415V 439.90V 390.10V 240V 254.40V 225.60V

MEDC Distribution System Capability Statement (2021-2023) – V2.0 5

2.5. Frequency Deviations Distribution Connection Conditions Code (DCC) 4.2 states the following:

During normal operating conditions, the nominal system frequency of the transmission and distribution systems is 50.00 Hz and normally will be controlled by OETC between 49.95 Hz and 50.05 Hz. During exceptional steady state conditions, frequency deviations will not exceed 49.90 Hz to 50.10 Hz unless disturbed circumstances prevail. Under disturbed conditions, System Frequency could rise transiently to 51.50 Hz or fall to 48.00 Hz.

2.6. Voltage Waveform Quality Distribution Connection Conditions Code (DCC) 4.3 states the following:

All apparatus and plant connected to the Distribution System and that part of the Distribution System at each connection point, must be capable of withstanding the distortions of the voltage waveform in respect of harmonic content and phase unbalance.

The maximum total levels of harmonic distortion on the Distribution System at 33kV and 11kV, from all sources under both normal, planned outage and fault outage conditions is required to not exceed a total harmonic distortion of 2.0%, with no individual harmonic greater than 1.5% unless abnormal conditions prevail. At Low Voltage (LV) the maximum total levels of harmonic distortion from all sources is required to not exceed a total harmonic distortion of 2.5%.

The maximum negative phase sequence component of the phase voltage on the Distribution System should remain below 1.0% unless abnormal conditions prevail.

A maximum value of 2.0% is permitted for phase unbalance.

2.7. Voltage Fluctuations Distribution Connection Conditions Code (DCC) 4.4 states the following:

Voltage fluctuations arising from disturbing or fluctuating loads connected at a connection point to the distribution system shall not exceed 1.0% of the voltage level for step changes that may occur repetitively. Any large voltage excursions other than step changes may be allowed up to a level of 3.0% provided that this does not constitute a risk to the distribution system or to any user.

2.8. Auto-reclosing and Single-Phase Protection Operation Distribution Connection Conditions Code (DCC) 4.5 states the following:

Users should be aware that MEDC may use auto-reclosing or automated sequential switching features on the distribution system. MEDC will on request provide details of the auto-reclosing or sequential switching features in order that the user may take this into account in the design of the user system and protection arrangements.

Distribution system users should be aware that the protection arrangements on some distribution systems may cause disconnection of one phase or two phases only of a three-phase supply for certain types of fault.

MEDC Distribution System Capability Statement (2021-2023) – V2.0 6

2.9. Design Fault Levels The design fault levels for the 33kV, 11kV and LV distribution system are stated in OES 11- General Specifications for Electrical Materials and Equipment and is shown in Table 3.

Table 3 : Short Circuit Rating of Switchgear

Voltage Level Rated Short Circuit Capacity 33 kV 25kA (1429 MVA) for 3 sec 11 kV 18.4kA (350 MVA) for 3 sec 11kV (New)* 25kA (476 MVA) for 3 sec LV 40kA (29MVA) for 1 sec

*Note that MEDC has adopted the standard rating for new 11kV primary equipment to be 25kA for 3 seconds.

The 33kV system is earthed via a 12.5 ohm neutral earthing resistor connected to the neutral point of each grid transformer, thereby limiting the maximum prospective 33kV earth fault current to 1,500 A per transformer. The 11kV system is solidly earthed.

2.10. Standard Equipment Sizes Conductors The standard 33kV to LV feeder conductors along with continuous ampere ratings used by MEDC are as specified in OES 1-33kV and 11kV Overhead Lines and OES 2-33kV & Pilot,11kV & LT underground cable installations are shown in Table 4, Table 5 and Table 6.

The continuous ampere ratings shown in Table 4, Table 5 and Table 6 are based on typical manufacturers data and de-rated for the standard installation conditions mentioned in OES 2-33kV & Pilot,11kV & LT underground cable installations. These ratings ensure safe working on the MEDC distribution system given the high temperatures experienced during the summer maximum demand period.

Transformers Standard 33/11.5kV transformer sizes are specified in OES 6-33/11.5kV Transformers as being 1, 3, 6, 10MVA ONAN and 20MVA ONAF, although other sizes such as 5 and 16MVA do still exist on the system. The overload capability above the transformer name-plate rating has been confirmed through modelling3 and supported by a limited number of measurements. MEDC has standardized on 20MVA ONAF transformers in the urban areas.

MEDC is studying the feasibility of increasing the 33/11.5kV transformer rating for new substations in areas of high demand density to cope with the high demand growth and the limitation of available land in such areas.

Standard as a minimum 11/0.433kV ground mounted transformer sizes specified in OES 5-11kV/433V distribution transformers are 1000, 500, 315, 200 and 100kVA, whereas 1250,1600,2000,2500 and 3000kVA distribution transformers do exist in the network. The most commonly used distribution transformers in the network are the ground mounted 500, 1000 and 2000kVA units; which form circa 87% of the distribution transformers on the system. The system also has a range of pole mounted transformers from 50, 100, 200 and 250kVA to be used as required.

Switchgear Minimum 33kV and 11kV switchgear ratings are specified in accordance to OES 14-11kV Indoor Switchgear and OES 15-33kV Indoor Switchgear as shown in Table 7.

Table 7 : Standard Switchgear Ratings

Voltage Description Ratings 33kV Feeder 600 A 33kV Bus Section 1200 A 11kV TX Incomer 1200 A 11kV Bus Section 1200/1250* A 11kV Feeder 400/630* A

*MEDC have adopted and standardised to these based on market availability

Capacitors All new 125 MVA grid substations are designed with a single 20 MVAr capacitor bank connected to each 33kV busbar section. All new 20 MVA primary substations are designed with a single 5 MVAr capacitor bank connected to each 11kV busbar section.

3 Based on IEC 60076-7 calculations

MEDC Distribution System Capability Statement (2021-2023) – V2.0 8

The capacitor banks are as specified in OES 13-11.5kV 5MVAr Capacitor Banks and consist of 5 x 1MVAr units with one set of capacitor banks connected to each bus section. The aim of the capacitors is to ensure that MEDC maintains power factor and voltage to be within prescribed limits to start with at the 11kV busbars but certainly at the 33kV busbars in accordance to the Grid Code.

2.11. Technical Standards In order that MEDC can operate a safe and efficient electricity distribution system all apparatus and plant associated with the connection to the distribution system are required to comply with the following standards, as applicable:

(a) Health and Safety Rules;

(b) Oman Electrical Standards (OES), which are such national standards as may be approved by and amended by the APSR as necessary;

(c) Grid Code;

(d) Distribution Code;

(e) The standards and recommendations of the International Standards Organisation and the International Electro Technical Commission (IEC); and

(f) national standards and codes, which are accepted internationally.

2.12. Specification of Apparatus and Plant The specifications of all connected plant are required to allow the safe operation of the MEDC distribution system within its operational procedures. Details of this can be obtained by contacting MEDC directly.

Apparatus and Plant must be suitable to use at the operating frequency and within the intended operating voltage range. This associated equipment should also be suitable to operate to the maximum design short-circuit rating of the distribution system to which it is connected having due regard to fault carrying capabilities including making and breaking duties. As necessary MEDC will provide additional details of the system at the point at which a specific connection is to be made.

Apparatus and plant must be operated within the thermal rating conditions contained in the appropriate standards, specifications, and other relevant publications, taking into account its intended use. Upon request MEDC will provide this information .

2.13. Earthing MEDC will provide advice on the method of earthing of the distribution system, for example, whether it is connected solidly to earth or through impedance. The specification of associated apparatus and plant of the connected customer equipment must meet the voltages that will be imposed on the apparatus and plant as a result of the method of earthing. The method of earthing must comply with the requirements of Distribution Connections Code Cl 5.2.1.

Users should take precautions to limit the occurrence and effects of circulating currents in respect of the neutral points connected with Earth where there is more than one earthed neutral point.

MEDC Distribution System Capability Statement (2021-2023) – V2.0 9

2.14. Voltage regulation and control Any extension or Connection to the distribution system should be designed so as to not adversely affect the voltage control employed by MEDC on the distribution system. MEDC will make information on the voltage regulation and control arrangements available if requested by the User.

2.15. Protection MEDC’s system and the system of any User must incorporate protective devices to ensure that apparatus and plant with electrical faults are disconnected from the system promptly and that the effects of faults on one system do not impose unreasonable risks to other systems.

To ensure satisfactory operation of the distribution system; protection systems, operating times, discrimination and sensitivity at the ownership boundary must be agreed between MEDC and the User during the process of application for Connection and may be reviewed from time to time by MEDC with the agreement of the User.

Back-up protection by operation of other circuit breakers or apparatus and plant having a similar function must normally be provided to safeguard the system against a circuit breaker, or apparatus and plant having a similar function, failing to operate correctly to interrupt the fault current on a high voltage system. During the process of application for Connection, MEDC will advise the User if back- up protection is not required.

Users must not use protection or associated equipment to limit the fault current infeed to the distribution system unless expressly permitted by MEDC to avoid protection operation malfunctioning loading to system assets exceeding short-circuit ratings.

MEDC Distribution System Capability Statement (2021-2023) – V2.0 10

3. PLANNING DRIVERS

3.1. Background MEDC’s electricity distribution system serves around 413,367 customers (as of July 2020) over an approximate area of 3,900 sq.km and is divided into three geographic zones. Figure 1 represents an overview of the MEDC distribution system within the Muscat Governorate including the system boundaries, zones, the GSS and 33/11kV circuits. The characteristics of the distribution system within the MEDC licence areas differ mainly because of three major parameters:

1) The load density; 2) The type and usage pattern of the customer; 3) The majority type of feeder circuits (i.e. overhead or underground).

The 2020 maximum demand4 recorded for MEDC system was 2322.9 MW (2445.2 MVA on Sunday - 05th July 2020 at 14:51 Hrs).

As of July 2020 the total existing number of 132/33kV grid substations is 355, 33/11.5kV primary substations connected to the MEDC distribution system is 177 with a Total Installed Capacity of 6,828 MVA and a firm capacity of 3,903.5 MVA. The tables identifying each Primary Substation capacity and current demand can be found in the Appendix D.

The sections remaining from this chapter provide the following:

1) An indicative geographical view of the complete MEDC distribution system and zone wise view of the grid substations, primary substations, 33kV and 11kV circuits; 2) A summary of the individual zone built up and the planning drivers for each zone; 3) It also provides an overview of the complete current MEDC system connectivity including the area classification for the primaries.

Area name classification in Table 8 -Table 10 below refers to the area what that PSS falls under and hence the associated Compound Annual Growth Area (CAGR) % being applied to that PSS. The concept of CAGR % and the area classification are explained in detail in Section 4.1.

4 The 2020 OETC system maximum demand day was on a different date (17th June 2020;afternoon at 14:41 Hrs). 5 The summation of the GSS in the table 8-10 shows 33 as two GSS namely Airport Height and Misfah are duplicated due to the dual feeder arrangements.

3.2. Zone 1 – (The Eastern Zone) The Zone 1 region includes the capital city of Muscat, Muttrah and an extensive rural network, which covers the wilayats of Amerat and Quriyat. The number of customers served in the Zone 1 region is 130,855 which is approximately 32% of the total customer population. Figure 2 below provides the geographical overview of the primary MEDC distribution system in Zone 1.

Figure 2 : Zone 1 Distribution System with PSS

Amerat has seen the highest demand growth for the last 5 years within the Zone 1 region validating for a significant demand growth forecasted for the current planning horizon.

The Muttrah Tourism Development project along with Yitti Tourism Development and Fins Project are the major upcoming development projects in the planning horizon of this DSCS as of yet. Table 8 below provides the GSS and primary distribution system connectivity for Zone 1.

4.2. System Demand and Load Duration The Maximum and Minimum Demand for the MEDC distribution system in 2020 is illustrated in Table 14 below. This shows that the 2020 minimum demand is circa 23.5% of the 2020 maximum demand for the MEDC system.

17 The CAGR% used for Misfah is based on an area with similar load characteristics as are created post 2014.

Table 14 : Maximum and Minimum System Demands

System Date & Time Load (MW) Load (MVA) Demand Maximum 2322.9 2445.2 05th July 2020 @ 14:51 Hrs Minimum 545.3 574 13th January 2020 @ 04:00 Hrs

MEDC note that the date of system maximum demand has fluctuated throughout the years. System maximum demand has occurred generally between the summer months starting from May to July; although there seems to be no exact co-relation on the exact timing as expected. There are various parameters which affect the occurrence of the system maximum demand hence the future forecast; we expect more parameters in the upcoming future especially due to the macro-economic condition of the Oman economy and due to the developments in newer technologies. Few of the significant parameters which have impacted MEDC distribution system growth in 2020 and future are :

1) Temperature and Humidity; 2) Customer nos and types of customer growth; 3) Socio-economic factors like state of economy due to oil prices; 4) Implementation of CRT and the continuous effect; 5) Impact of COVID-19 pandemic.

This can result in a lack of consistent predictability as to the precise date of future system peaks; although provides a good indication in general of the period and pattern. For this reason; associated demand transfers are operationally planned to occur before May period each year to ensure MEDC are in the best position possible to meet regulatory requirements and ensure quality and security of supply to consumers.

Figure 5 below indicates that from the historical data [2013-2020]; the system maximum demand day load profile pattern is generally consistent with each other18. As it can be seen from Figure 7; the maximum demand % growth i.e. growth magnitude has been inconsistent especially between 2013 and 2020; due to the factors mentioned above.

The maximum demand data is supplemented with the associated load duration curve shown in Figure 6. This graph below represents a period of last 9 months (Jan – Sept 2020). The peak demand was circa 63% of the firm capacity [3,903.5 MVA / pf (0.95) =3708.3 MW] and the system load is greater than 1500MW for circa 54% of the time during the measurement period as indicated in Figure 6 below along with the spread of load against the no of hours for the year. The associated distribution and utilisation of MEDC’s distribution assets are seen to be generally in line with common distribution utility practice.

Figure 6 : Load Duration Curve

Similar to the system maximum demand, the date of system minimum demand has fluctuated throughout the years. System minimum demand has occurred generally between the winter months starting from January to February between 03:00 AM to 05:00 AM. Figure 7 illustrates that the system maximum/minimum demand including grid connected customers and total customer nos. have generally grown year on year following a similar growth trend.

4.3. Cost Reflective Tariff (CRT) In October 2016, The Regulator announced that the Council of Ministers had approved the introduction of a new tariff for high value customers called the Cost Reflective Tariff (CRT) and implemented fully in 2017. The new tariff is designed to more accurately reflect the actual costs of providing a supply of electricity to large government, commercial and industrial customers without government subsidy. The current approval for CRT implementation is for application only to the high value customers who consume 150 MWh and above in a year, for the above-mentioned customer categories.

As the full 2020 cycle hasn’t been completed yet an impact analysis was undertaken on 2019 MEDC customer base to understand the full year impact of CRT on the MEDC distribution system and described as below.

The number of CRT customers in 2019 was 5138, circa 1.3% of the total connected customers and as shown in Figure 8 this 1.3% of the CRT customers out of the MEDC total customer base consumed 39.3% of total energy distributed by MEDC in 2019.

Figure 8 : MEDC 2019 CRT and Non-CRT Units Sold (MWh)

2019 CRT & Non CRT Units Sold (MWh)

4,526,949 6,980,243 39% 61% CRT Non CRT

Post implementation of the CRT; the revenue realization per MWh for 2019 MEDC CRT customers was 26.01 OMR. The economic cost of electricity supply in MEDC was approximately 28.3 OMR per MWh in 2019; hence this results in a government subsidy of circa 2.3 OMR per MWh for CRT customers. As a total this resulted in a government subsidy of circa 10M OMR for CRT customers in 2019 compared to circa 22M OMR in 2018 resulting in net reduction for government subsidies.

The average realization rate across all customers (non-CRT to CRT from 2019) per MWh for MEDC in 2019 was 18.33 OMR/MWh compared to 17.73 OMR/MWh in 2018.

The effect of CRT implementation on the MEDC system maximum demand profile is quite evident in the form of peak shaving; especially due to the industrial customers.

From the observed 2020 load curve on the MEDC system maximum demand (05th July 2020); as an example two large industrial customers normally consuming circa 30MW of demand have reduced there load contribution to the MEDC system maximum demand during the peak hours (i.e. 1:00 pm to 5:00pm) of the week to effectively zero in comparisons to previous year’s as visible from the demand profile’s in Figure 9. As seen from Figure 9 Industrial customer no.1 load on the MEDC system reduced from the normal circa 7MW during the peak hours in 2017 to circa 0MW in 2018 ,2019 and 2020.

4.4. Demand Not Secured (DNS) As per the licence condition; MEDC is obliged to comply with the DSSS and moreover one of our major investment drivers for the CAPEX programme is to meet the N-1 operational capability for each Primary Substation.

Figure 10 below provides a trend of the MEDC Demand Not Secured (DNS) MVA performance; as a measure to show DSSS compliance improvement along with number of Primary Substations contributing to the DNS. It can be seen that in the recent years the DNS performance in consistently improving and the unaudited 2020 DNS for MEDC realised is 46.4MVA which is a circa 74% reduction compared to 2019 DNS value of 178.1MVA.

MEDC distribution system predominantly is a urban dense interconnected network and as part of network design optimum effort is made to maintain that level of interconnection leading to majority of the 11kV feeders except minor rural feeders having not single but multiple interconnections. Hence majority of the 11kV feeders will come under the Class A and Class B categories. Typically with the assistance of these 11kV interconnections, the supply can be generally restored within the allowed DSSS time frame.

4.5. 11kV Feeder Loadings As detailed in the Table 15 below six non-compliant 11kV feeders were observed in 2020 which exceeded the thermal loading limit under normal operational configuration; these will be solved by appropriate 11kV load transfers, reinforcement schemes and/or automation in 2021 itself.

4.6. System Demand Forecast Accurate and realistic load demand forecasting is critical for the effective operation of the distribution system and is the principal driver for capital expenditure. Realistic assumptions must be made for inherent uncertainties in forecasting and the underlying socio-economic factors, such as the sustained low oil price and exceptional events like the COVID-19 pandemic for 2020.

Load growth can vary from year-to-year and is not uniform across the whole system. It is not unusual to find parts of the system growing at significantly higher rates than for the system as a whole, while other parts of the system can experience periods of low growth or demand reduction.

MEDC high voltage distribution system operates at 33kV and 11kV, both voltages being standard IEC voltages. The 33kV system is normally operated with duplicated radial while the 11kV system is operated as a radial configuration, normally with interconnection through normally open points except

MEDC Distribution System Capability Statement (2021-2023) – V2.0 27

in the more remote areas. The system covers both urban and rural areas and the characteristics depend on the load density.

Distribution Load Forecasting MEDC considers the following features are necessary to produce an accurate demand forecast in line with best practice:

• Accurate and unbiased actual demand data – careful management of data and forecasting model construction based on sound theoretical grounds that closely fits the sample data. • Transparency and repeatability – as evidenced by good documentation, including documentation of the use of judgment, which ensures consistency and minimises subjectivity in forecasts.

MEDC also considers the following elements to be relevant to maximum demand forecasting:

• Independent forecasts – spatial (bottom up) forecasts should be validated by independent system level (top down) forecasts and both spatial and system level forecasts should be prepared independently of each other. The impact of macroeconomic and demographic trends is better able to be identified and forecast in system level data, whereas spatial forecasts are needed to capture underlying characteristics of specific areas within the system. Generally, the spatial forecasts should be constrained (or reconciled) to system level forecasts; • Adjusting for temporary transfers – spatial data is adjusted for historical spot loads arising from peak load sharing and maintenance, before historical trends are determined; • Adjusting for discrete block loads – large new developments, such as shopping centres and housing developments, are incorporated into the forecasts, taking account of the probability that each development might not proceed. Only block loads exceeding a certain size threshold are included in the forecasts, to avoid potential double counting, as historical demands incorporate block loads and general demand growth.

At the time of writing this DSCS, the volume of grid connected PV systems is expected to make minor impact at system level forecast (including future years as it stands); hence the impact of PV systems is not included in the forecast for this DSCS. With the development of our new regression-based Load Forecasting tool, MEDC will monitor the uptake of all low carbon technologies including PV and include the impact of these on forecast in future appropriately.

System Demand Growth Historical data indicates that the demand rate of growth across MEDCs distribution system has slowed in recent years. This is mainly attributed to the sustained low price, general macro-economic factors and exceptional events like the COVID-19 impact. Over the 2013 to 2020 period the CAGR % system- wide load growth was as shown in Table 16.

Table 16 : CAGR% Evaluation on the System Maximum Day

2013-2020 CAGR system load System Maximum Demand growth % Non-Grid connected customers 4.0% Grid connected customers 4.2% After the declaration of maximum and minimum load in 2020, the minimum to maximum load ratio % was calculated for each PSS. The calculated ratio % of each PSS was then applied in the maximum forecasted load [2021-2023] to forecast the minimum load.

MEDC Distribution System Capability Statement (2021-2023) – V2.0 28

Table 18 and Figure 11 shows the historical trend in system maximum demand with the forecast maximum demand over the period 2021 to 2023. Despite the general slowing in demand growth at the system level, there are areas within the system where maximum demand is forecast to grow well beyond the system average level, while other parts of the system are forecast to experience no load growth or a small reduction in maximum demand. This particularly applies to Muscat and Muttrah (except any potential bulk load connections) where the geography of the area (city area predominantly domestic property) can be considered saturated with little room for property expansion. Significant demand growth is expected in the South of Zone 1 and Zone 3, largely due to new developments associated with urban sprawl towards the edge of the urban growth zone. As a result of this urban sprawl, we expect to see continued strong growth in the Amerat and Mabelah areas. Similarly as seen in Table 18 and Figure 11 the forecast includes the impact of COVID-19 on the future growth period as well, as it is expected to take few years before the normalisation to pre COVID levels is reached.

• COVID-19 Pandemic Impact

The maximum demand growth was significantly reduced by -6.3% in 2020 and the exceptional drop is majorly attributed as impact of the exceptional COVID-19 pandemic situation. The reduction in the growth due to the COVID-19 has mainly resulted from shutdown of commercial activities, Government institutions and Ministries with less occupancy, citizens returning to the interior during the working from home arrangements and closing of Mutrah Souqs impacted the load in Muscat/Muttrah area. Similarly as expected there is an increase in the residential loads during these period due to people working from home and complete families not able to travel outside during summer vacations.

As an indication only the Table 17 below highlights the significant impact on the last summer peak load of some large customers from the following customer categories as an impact of COVID-19.

Table 17 : Covid-19 summer load 2020 impact

Average Summer Load Impact Customer Category compared to last year Commercial -20%

Governmental -15%

Tourism -40%

Residential 20%

Especially, in the last three years the maximum demand year on year growth at system level has reduced and dropped to 0.8% in 2018 and 4.7% in 2019 and -6.3% in 2020 as seen in Table 18; MEDC shall closely monitor the growth for the remaining years of the PCR-5 period and reflect the effects in the coming years as necessary for the reasons below:

1) The period when the reduction is observed is very small to be confident to change the growth % for the upcoming years; especially that MEDC expect the % growth to change compared to recently observed in the coming years as the price of oil continues to improve as evident from the 2018 to 2019 maximum demand growth; 2) Secondly we expect additional parameters like new technologies; photovoltaics and electric- vehicles to impact the pattern of the growth; 3) Thirdly as also observed from the table below in periods 2010-2012 and 2013-2015 have seen drastic swings in the system growth percentage due to a multitude of factors in a very short period

MEDC Distribution System Capability Statement (2021-2023) – V2.0 29

of time i.e. MEDC believe that a larger period is required to determine the future growth percentage rather than last 2-3 years only and exceptional event impacts to be excluded. 4) Lastly MEDC believes that it will take some time before the growth reduction due to COVID-19 impact is normalised to pre-levels; hence no further growth reduction is expected.

4.7. Grid Supply Points By 2023, it is forecasted that there will be 38 grid supply points within the MEDC licenced area. There are 2 new grid supply points(each GSS with 4x125 MVA TX ;Group A &B) currently in the construction phase. The investment drivers for grid supply points is to relieve existing overloaded (above the firm) grid supply points and to provide new 33kV connection points to accommodate new primary substations. MEDC provides annually a demand forecast for five years to OETC. The existing system (2020) and expected system development for the primary substations is updated in Figure 12 and Figure 13 [expansion for the next 3 years].

MEDC Distribution System Capability Statement (2021-2023) – V2.0 33

4.8. Distribution System Modelling and Analysis MEDC maintains up-to-date models of its power system for assessing distribution system performance via power system studies, bulk loads modelling and undertaking customer connection studies where required; to ensure the distribution system operates in a safe and an efficient manner along with providing the required security of supply to its connected customers.

Power System Models The planning tool utilised for system modelling and studies is PSS®SINCAL (Power System Simulator® Siemens Network Calculation). The models for each grid substation with their respective connected primary substations are established by representing the 33kV system on an electrical connectivity basis. The system models contain network topology and details in terms of nameplate data for transformers and their tap changers, capacitor banks and their controllers, conductor types along with associated lengths and parameters and the non-coincident demand data on individual primary substations.

The load demands are modelled as lumped loads connected to the main 11kV bus bars and segregated into motoric and non-motoric load types for load flow and fault current calculations. The recorded maximum (summer) and minimum (winter) demands on each primary substation; derived from MEDC SCADA system as of 2020 have been used to update the power system models. Forecasting principles for load determination as mentioned in the previous sections have been adopted to forecast the future year (2021-2023) maximum and minimum demands.

Under minimum demand conditions; the reactive power support from primary substation and grid substation capacitor banks is switched off to avoid overvoltages.

Load Flow Analysis Load flow analysis is undertaken for maximum and minimum demand scenarios to define the performance of MEDC distribution system during these two-extreme loading scenarios. The analysis determines the active and reactive power flows in the system, percentage loadings for transformers and 33kV circuits along with the voltage profile at the 11kV and 33kV busbars of the primary substations under normal circuit operation. Simulations are carried out for the existing (2020) and future 3 years (2021-2023) for system maximum and minimum loadings.

From the studies of these extreme conditions it is possible to identify where the system is strong and has spare capacity and conversely, where additional mitigation and/or reinforcement, before new connections, potentially needs be considered. The maximum demand case for instance; identifies where there is a risk of overloading, of operation above firm capacity, or of system voltages falling below the voltage limits whereas the minimum demand case will recognize voltage excursions above statutory limits as defined in the Distribution Code.

The power factor values for maximum and minimum demand scenarios have been determined based on the actual available information from MEDC SCADA. For maximum demand conditions; the actual recorded power factor data is employed, where available, for 122 primary substations. For the remaining 55 substations; where power factor values are not available via SCADA, a calculated system average of 0.93 and 0.90 is considered for maximum and minimum demand scenario’s respectively in accordance to the company’s defined practice.

MEDC Distribution System Capability Statement (2021-2023) – V2.0 34

The load flow study results are summarised in tabular form in Appendix D and available in a downloadable excel file that supplements this Distribution System Capability Statement.

The simulation result demonstrates the following:

• Voltage drop under maximum demand scenario remains within the statutory limits of - 6% on all 33kV busbars/nodes. • Voltage drop under maximum demand scenario remains within the statutory limits of - 6% on all 11kV busbars/nodes. • Voltage rise under minimum demand scenario remains within the statutory limits of + 6% on all 33kV busbars/nodes. • Voltage rise under minimum demand scenario remains within the statutory limits of + 6% on all 11kV busbars/nodes; in case of very minor excursions in 2020, the problem solves in forthcoming years. • 33kV circuit loadings assessed for the worst-case maximum demand scenario; across the system are within the acceptable circuit ratings.

From the results it can be observed that especially under minimum demand case, the 11kV buses at the primary substations are approaching the statutory limit of +/-6% in some of the primary substations and slightly exceeding +6% in one PSS (Madinat Al Nahdah – P065 - Bus B) for all the three future years cases. This is explained by the fact that our primary transformers are rated at 11.5kV secondary voltage and to represent the worst case scenario; the load flow calculations are performed with tapchangers switched off, which on the ground will otherwise regulate the voltage performance better and remain within statutory voltage limits.

Short Circuit Analysis MEDC carries out short circuit calculation studies to establish the capability of equipment to withstand three phase maximum prospective fault current levels.

The principal source of fault currents is the generation assets connected to the transmission system with the fault current contribution onto the MEDC distribution system via the 132/33kV GSS transformers. The fault current infeed from the OETC source have been updated in our power system models according to the data provided by the OETC’s 2020 Capability Statement which covers up the transmission system developments up to 2024.

The system configurations modelled for short circuit studies in each year, to represent the maximum prospective fault current levels, while also reflecting the realistic operational arrangement are based on the following principles:

• All existing and new 2x20 MVA PSSs are simulated for operation with the 11kV bus-section circuit breaker in the “normally closed” position20.

20 Except for few locations where the 33kV feeders for the individual transformers are connected from two different GSSs in which case, the 11kV bus-section circuit breaker is kept “normally open” for the respective year(s).

MEDC Distribution System Capability Statement (2021-2023) – V2.0 35

• All existing and new 3x20 MVA PSSs are simulated for operation with one 11kV bus-section circuit breaker as “normally closed” and one as “normally opened” (i.e. in N or N-1 scenario, it represents a 4 out of 5 ‘normally closed’ circuit breakers scenario) with an auto-changeover scheme 21. • All existing 2x20 MVA PSSs and 3x20 MVA PSSs are simulated for operation of 33kV bus-section circuit breakers within the PSSs (where ever present)22 as “normally open”.

The design short circuit breaking ratings of the 11kV switchgear components at new and upgraded primary substations have been revised to 25 kA to comply with system requirements23.

Currently, in the absence of accurate fault level contribution data from low voltage (LV) side, a worst- case allowance is made for LV motor fault contribution majorly due to the nature of the air conditioning load prevalent across the MEDC’s distribution system. A motoric to static load type ratio of 80/20 (in percentage) is considered using the system maximum demand values. System modelling for fault current calculations have been performed in accordance with the principles of the “IEC 60909-Short Circuit in 3 phase AC systems” standard.

The maximum prospective fault current values are tabulated in the tables in Appendix D. The calculation of maximum prospective fault current is compared against the rated breaking capability of the primary equipment.

The maximum prospective (initial symmetrical) fault current is calculated to be still under but approaching (i.e. >95% and <100% ) the rated breaking capacity of the primary 33kV equipment (switchgear) at the following primary substations:

• Wadi Adai Grid Primary – P175 (23.86 kA in 2022 and 2023) • Bousher Grid Primary - GP02 (24.38 kA in 2020 and then within 96% of 25kA rating) • Mabelah Grid Primary - GP04 (24.85 kA in 2021 and then within 95% of 25kA rating) • Seeb Grid Primary – GP08 (23.75 kA in 2022 and then within 95% of 25kA rating) • Mabelah South 9-A – P184 (23.94 kA in 2023)

However, at the following primary substation(s), minor excursions beyond the rated breaking capacity of the 33kV equipment (switchgear) are observed :

• MSQ Grid Primary – GP06 (25.54 kA in 2022 and 2023) where it marginally exceeds by +2.16% above the switchgear rating; hence MEDC shall monitor this PSS closely and create mitigation plans in form of operational restrictions if required based on the monitoring results.

It is to be noted that all the above primary substations are in close electrical vicinity of the grids substations where these results are based on non-coincident maximum demand fault contributions to represent worst case scenario’s of the connected PSSs.

21 If the fault levels are within limits for this worst case scenario’s then on bus-coupler open scenario’s of existing primaries the fault level’s will be even lower. 22 For new PSS, the 33kV configuration excludes the 33kV bus-section circuit breakers at the PSS. 23 For the older existing 11kV indoor type switchgear where applicable, the rated breaking short circuit current value is 18.4kA.

MEDC Distribution System Capability Statement (2021-2023) – V2.0 36

The maximum prospective (initial symmetrical) fault current levels at 11kV busbars of all the primary substations are within their rated breaking capacities.

Technical Losses Assessment The technical losses in the MEDC distribution system are a factor of the configuration of the system, type and specification of equipment, percentage utilisation of assets and customer energy consumption. Technical losses are attributed to load and no-load losses in the 33kV feeders and 33/11.5kV primary transformers, 11kV feeders and distribution transformers and the LV distribution system. In line with standard international practice for utilities where the distribution system is not fully modelled, we calculate the losses for specific network elements (transformers, overhead lines and cables) across the different voltage levels (33kV, 11kV and LV) and then summate the total losses to obtain a percentage technical loss for each primary substation.

The percentage technical losses are then apportioned according to the proportion of total system energy supplied by each substation. A summation of all apportioned technical losses is then presented as the system percentage technical losses. The summated technical losses based on the 2020 distribution system operation is estimated to be 3.98%. The breakdown of technical losses by voltage level is shown in Table 19 below.

Table 19 : Technical Losses

System Component Loss Value 33kV Circuits 0.16% 33/11.5kV Primary Transformers 0.46% 11kV Circuits 0.59% 11/LV Distribution Transformers 1.77% LV network 1.00% Total 3.98% 4.9. Continuous Improvement Areas MEDC have progressed on previously identified areas of continuous improvement as listed below and is continuing its working on the same along with identifying new areas where required.

1) Bulk Load Details and Modelling

We are continuously collating the details of existing 33kV and 11kV bulk customers to incorporate in MEDC power system models as appropriate. Creation of processes and automation including a creation of a Bulk Load Database to record accurately point of connections, customer power system impact including short circuit contribution to MEDC distribution system and agreed capacities to consistently capture these for existing and new customers have been created to effectively progress in this area. This has led to continuously adding further bulk loads at 11kV with their more accurate fault current contributions added to our base master models.

2) 11kV System Modelling

In 2020 MEDC completed the creation of a robust methodology for achieving MEDC requirements for developing power system models for 11kV system up to the main LV bus bar along with Siemens. Siemens along with MEDC implemented the methodology on one typical GSS model and post that in 2020 MEDC staff have already completed the full detailed 11kV modelling on 11 GSSs (A & B groups counted as one) in house, aiming to finish the remaining GSSs before end of Q1 2021. The exports from GIS are based on up-to-date 11kV network information into PSS®SINCAL readable format. This

MEDC Distribution System Capability Statement (2021-2023) – V2.0 37

will not only enable us to improve our existing power system studies and technical losses calculations using PSS®SINCAL but also supportive in point of connection studies for load connections and grid impact studies for renewable energy connections as well. Point 3 below shows the initial progress for the 11kV system modelling as well to reflect the real scenarios on ground.

3) Improved and Updated Motoric Short Circuit Contribution

We aim to assess the motor fault contribution onto MEDC’s system at LV due to the connection of typical larger scale centralised commercial air-con units by obtaining typical details of such systems from our larger commercial customers and preparing sample equivalent connection impact studies.

We are undertaking assessment studies for MV motor fault contribution from larger industrial customers in relevant parts of the system to improve the fault current calculations. This is an ongoing actvitiy and to that effect since 2018, we have further enhanced our network models at 4 PSS already (namely Jibrooh-P041, Mawalleh North Grid-GP01, Al Khoudh Ph 06 – P049 and Mall of Oman - P171) and 2 dedicated customers (Ad-Dakhiliyah Water Pumping Station and Mall of Oman development representing a fault infeed of 2.84kA and 2.44kA at 11kV respectively) to appropriately reflect the expected fault current contribution onto our distribution systems.

MEDC recently in 2019 completed an innovative prospective fault level monitoring project; based on the actual measured network conditions which has given us initial answers around fault level contributions from upstream transmission grid as well as downstream motor loads onto LV and MV networks. We aim to do further monitoring trails to firm up the initial answers going forward and improve the mortoric short circuit contributions from different types of loads on the distribution system.

4) Technical Losses Calculation using Power System Models

As detailed in point 2, once all the 11kV network models are established which are already under progress in 2020, we plan to merge our 33kV and 11kV models and furnish them with annual load profiles to produce technical losses from the models using 8760 hourly annual measured loadings from the SCADA load profiles.

5) Voltage Control and Regulation Methodology

As an additional improvement item, MEDC is in process of developing an improved voltage regulation methodology at our primary substation 11kV busbars by assessing the SCADA data on present/typical transformer tap positions and capacitor banks during summer and winter times. We have made great progress on the 33 and 11kV existing capacitor bank availability and operation. This is ongoing to enable us to assess optimal target voltage requirements and the 33 and 11kV capacitor bank availability and operational philosophy improvement last year is helping in improvement of technical losses and better voltage profile on the extremities of the system. This will also create potential for further economic development of the system especially in the rural areas with additional extension possibilities provided by these solutions.

5. CHALLENGES AND OPPORTUNITIES WITHIN THE SYSTEM

MEDC recognise that the nature of electricity generation and use is changing. We envisage that recent policy initiatives will result in an increase in photovoltaic (PV) generation on our distribution system. Unlike other utilities in different regions, Oman has not seen significant uptake in electric vehicle charging thus, the associated demand characteristics for electric vehicles (EV) are not considered to be a contributing factor to our system planning in the short term planning horizon. However; this will be closely monitored to check the penetration rate of EV and PV in general.

With the introduction of Sahim-I initiative by the APSR since May 2017 there has been an increasing uptake of small grid connected PV systems for households and business as evident from the PV connections list in Appendix C. Similarly with the recent 2019 launch of Sahim-II aimed at encouraging the small grid connected PV systems (circa 3-5kWp) for residential rooftops; MEDC expect even greater rate of uptake (APSR forecasting circa 10-30% residential premises24). With this great rooftop PV intiatives, MEDC does foresee challenges and opportunities in the way we will plan and operate our system. Whilst PV may have the impact of reducing transmission and distribution congestion; we do envisage that challenges in terms of power quality, reverse power flow and operating within voltage limits will need to be addressed if PV uptake is significant.

MEDC are responsible for ensuring power quality according to the regulations under which we operate. However; with the addition of intermittent, consumer-owned and non-dispatchable PV units, current standard procedures for guaranteeing power quality might not be as effective as they are without PV.

Overvoltage is one of the main reasons for limiting the capacity (active power) of non-dispatchable PV; that can be connected to a low voltage Distribution System. During high PV generation and low load periods; there is a possibility of reverse power flow and consequently voltage rise in the HV & LV feeder. We envisage that this will be most prominent during the winter period. For this reason; MEDC believe that if uptake is significant it will impact investment decision making for reinforcement and asset replacement. Consideration of tap range, optimum dispatch of capacitor banks and conductor sizing may be necessary should PV penetration become high.

5.1. New Connection Applications MEDC are responsible for the connection of customers for all levels of demand that our system supplies. We are also the initial point of connection request for customers seeking a 33kV or 132kV connection at an OETC grid supply point.In 2020, we have received 19 bulk connection requests with a combined total demand of 134.1MW. 11kV and lower voltages connection applications are identified in Table 20.

Photovoltaic (PV) connections With the global trend of renewable energy technologies and the reduction of using fossil fuels, MEDC continued to receive applications for connecting solar PV systems of various sizes. In 2020, MEDC received 38 new applications with total requested generation capacity of 1.083 MW. In 2020; 10 no. applications energized were connected equating to 817.4 kW, 12 no. applications are under construction (including applications from 2019 which are still under construction) equating to 1.368 MW. Table 21 below shows these customer classifications for the applications and connections along with the total connected generation to MEDC network equating to 4.08MW (as of October 2020 since the start of PV installations).

Appendix C has the complete details of the 2020 applications.

5.2. System Constraints and Opportunities Load related system constraints fall into one of two categories:

• Current constraints that can be considered DSSS obligations. • Load related constraints based on current load growth forecasts. MEDC will seek to address such constraints as part of its investment plan. Demand Not Secured (DNS) non-compliances are identified and documented within Appendix B.

Table 22 provides a list of projected capacity constraints at the end of the planning horizon in 2023. If the value is identified as negative, MEDC envisage there will be a deficit in spare capacity at that specific substation, thus it is less advantageous for a customer to consider a new connection in that area. Likewise, if there is spare capacity (positive), then this substation may be considered more advantageous as a point for new customer connection.

APPENDIX D: SYSTEM STUD Y R E S U L T S

Appendix D presents the following series of tables, for each grid substation power system model, which show the expected performance of the distribution network under maximum and minimum demand scenarios for each year from 2020 to 2023.

1. Primary Substations Maximum Demand and Percentage Loading The maximum demand with real and reactive power loads at the PSS individual peak time in 2020 planning cycle and as accordingly forecasted for the period from 2021 to 2023. Percentage loading is calculated based on the Firm Capacity of the PSS. This data was used in the load flow and fault level studies for maximum demand scenario presented in this section of this DSCS.

2. Primary Substations Minimum Demand and Percentage Loading The minimum demand with real and reactive power loads at the PSS individual minimum time in 2020 planning cycle and as accordingly forecasted for the period from 2021 to 2023. This data was used in the load flow studies for minimum demand scenario presented in this section of this DSCS.

3. 33kV Feeder Loads The resulting maximum demand in MVA on 33kV circuits/feeders, calculated for the individual non- coincident maximum loads of the PSS(s) connected to these feeders for the period 2020 to 2023. Percentage loading is calculated based on the de-rated capacity of the circuits.

4. Primary Substations Bus Voltages The resulting voltage value (expressed in percentage of the nominal 33kV and 11kV) on the busbars of the PSSs, corresponding to maximum and minimum demand scenarios.

5. Primary Substation 3-Phase Fault Current Levels (kA) The resulting 3 phase maximum fault current level on the busbars of the PSSs, corresponding to maximum demand scenarios. The rated breaking fault ratings of the switchgear are also specified.

Explanatory Notes: a) 1TX in Firm Capacity means primary substation has single 33/11.5 kV transformer (i.e. zero N- 1 capacity and firm capacity equivalent to 11kV interconnection capacity); b) Standby PSS means primary substation having 33kV and 11kV busbars energized with 11kV outgoing feeders (i.e. loads) disconnected. The load on these PSSs is expected to be connected occasionally, depending on requirement.

In the above mentioned tables, a “-“ (dash) appears in relevant years due to any of the following reasons, as may be applicable:

− The primary substation is shifted (i.e. connected) to another grid substation; − The primary substation, or any of its capacity enhancement project, is planned to be energized/commissioned in the future; − There are no 11kV busbars (rather a different voltage level exists e.g. 6.9kV for a private customer, operated and maintained by the customer); − MEDC doesn’t have the information of the network below 33kV level.

APPENDIX E: INFORMATION ON DISTRIBUTION SYSTEM ASSET S

Appendix E presents the following series of tables, for each grid substation power system model in form of complete technical asset data as of 2020.

Appendix E1 – 33kV Circuits/Feeders Data Appendix E1 presents the circuit length from gird substation up to the 33kV busbar in the primary substation. It specifies the key parameters for the circuits including resistance, reactance, capacitance and the continuous derated thermal rating for the underground cable and overhead line conductor types used. The resistance is specified at 20C AC values.

Explanatory Notes: a) 33kV UGC 300 3C Cu means 33kV underground cable of 300 sq.mm. cross-sectional area, three core type and formed of copper conductor; b) In general, the cables employed are XLPE insulated and armored; c) 33kV OHL 200 Panther ACSR means 33kV overhead line of 200 sq.mm. cross-sectional area (i.e. Panther conductor) of Aluminium Conductor Steel Reinforced type; d) 33kV OHL 100 Dog ACSR means 33kV overhead line of 100 sq.mm. cross-sectional area (i.e. Dog conductor) of Aluminium Conductor Steel Reinforced type; e) Where a single 33kV feeder feeds multiple primary substations [for e.g. circuits in rural areas], the circuit length between the grid substation and each of the connected primary substation on that feeder is calculated and captured individually. This means that there will be few duplicated segments of circuit length. This is explained with the following example:

Hence, the 33kV circuit lengths as documented for;
