Page 7 SEPD May 2021 LTDS SUMMARY INFORMATION
1 GUIDING PRINCIPLES FOR PLANNING THE DISTRIBUTION SYSTEM
The following standards are the guiding principles which underpin the policy for planning and designing the distribution network in Southern Electric Power Distribution plc: Licence Conditions Distribution Code Electricity Safety, Quality and Continuity Regulations Environmental Standards Company Internal Standards
2 STANDARDS
2.1 Licence Conditions
2.1.1 Pursuant to a licensing scheme made by the Secretary of State, under part II of Schedule 7 to the Utilities Act 2000, Southern Electric Power Distribution plc has been granted a licence under section 6(1) (c) of the Electricity Act 1989 authorising it to distribute electricity for the purpose of giving a supply to any premises in the area specified in Schedule 1 of the Act.
2.1.2 Standard Licence Condition (SLC24) (para 1) - Distribution System Planning Standard and Quality of Supply - requires the licensee to plan and develop the distribution system in accordance with a standard not less than that set out in Engineering Recommendation (ER) P2/7.
In accordance with SLC 24 (para 4) the Authority (Office of Gas and Electricity Markets - OFGEM) may, following consultation with the licensee, issue directions relieving the licensee of its obligation under para 1 (as stated in the above paragraph) in respect of the licensee's distribution system and to such extent as may be specified in the directions.
In order to meet the above standard our policy is to plan networks at the most economic cost. To achieve this, we have taken two approaches: For high volume works where point of connection is low voltage (230 and 400 V) or high voltage (11 or 6.6 kV) we have standard connection arrangements which ensure compliance with ER P2/7. For lower volume, high cost developments, principally at EHV, i.e. 132, 66, 33 and 22 kV, we will tailor development to meet standards on an individual basis to optimise cost-benefit and customer requirements.
Page 8 SEPD May 2021 LTDS 2.1.3 Under SLC 12 - Requirement to Offer Terms for Use of System and Connection - the licensee shall, on application, offer to enter into an agreement (Connection Agreement) for use of system.
Where the licensee makes an offer to enter into a connection agreement, the licensee shall, in making the offer, make detailed provision regarding: The carrying out of the works required to connect the licensee's distribution system to any other system for distribution of electricity. The carrying out of works in connection with the extension or reinforcement of licensee's distribution system rendered appropriate by reasons of making the connection. The installation of appropriate meters required to enable the licensee to measure electricity being accepted into the licensee's distribution system at the specified entry point or leaving such systems at the specified exit point. Installation of such switchgear or other apparatus (if any) as may be required for the interruption of supply where the person seeking connection or modification of an existing connection does not require the provision of top-up or standby. The charges to be paid in respect of services required. For the purpose of determining an appropriate proportion of the costs directly or indirectly incurred the licensee shall have regard to the benefit to be obtained or likely in the future to be obtained.
In determining the costs of connection of demand and generation, the licensee shall apply the charging principles set out in the annual charging statements including, where applicable, application of: Cost apportionment of any necessary reinforcement for the Connection; and, Distributed Generation Incentives.
The statements which set out the basis of charges for "Use of System" and "Connection to the Distribution System" are entitled: Statement of charges for use of Southern Electric Power Distribution plc’s distribution system; Statement of charging methodology for use of Southern Electric Power Distribution plc’s distribution system. Statement of charging methodology for connection to Southern Electric Power Distribution plc’s distribution system.
(All the above as amended from time to time.)
All the above statements are available on our website www.ssen.co.uk or by sending an email to [email protected]
Page 9 SEPD May 2021 LTDS 2.2 Distribution Code
Under SLC 20 of the Licence the licensee shall prepare and at all times have in force and shall implement and comply with the Distribution Code.
The Distribution Code covers all material technical aspects relating to connections to and the operation and use of the licensee's distribution system or the operation of electric lines and electrical plant connected to the licensee's distribution system.
It requires the licensee's distribution system to be designed so as to permit the development, maintenance and operation of an efficient, co-ordinated and economical system and to facilitate competition in the generation and supply of electricity.
The Distribution Code includes: A distribution planning and connection code containing: Connection conditions specifying the technical, design and operational criteria to be complied with by any person connected or seeking connection to the licensee's distribution system; and Planning conditions specifying the technical and design criteria and procedures to be applied by the licensee in the planning and development of the licensee's distribution system and to be taken into account by persons connected or seeking connection with the licensee's distribution system in the planning and development of their own plant and system; and A distribution operating code specifying the conditions under which the licensee shall operate the licensee's distribution system and under which persons shall operate their plant and/or distribution systems in relation to the licensee's distribution system, in so far as necessary to protect the security and quality of supply and safe operation of the licensee's distribution system under both normal and abnormal conditions.

See Section 7 for enquiries relating to the Distribution Code.
2.3 Electricity Safety, Quality and Continuity Regulations
The Secretary of State issued The Electricity Safety, Quality and Continuity Regulations in 2002 in order to: Ensure that the electricity supplies are regular and efficient. Protect the public from dangers arising from distribution of electricity, use of electricity supplied or from installation, maintenance or use of any electricity line or electrical plant. Eliminate or reduce the risks of personal injury or damage to property or interference with its use.
Regulation 27 gives permitted variations at all low voltage customers' terminals of +10% and -6% of the declared voltage of 230 V single phase or 400 V three phase. For higher voltages below 132 kV the permitted variations are between +6% and -6%
Page 11 SEPD May 2021 LTDS of the declared voltage, and at 132 kV or above they are between +10% and -10% of the declared voltage. It is therefore necessary to hold the system voltage within these ranges on all systems to which customers are connected, i.e. all low voltage systems, most HV systems and some EHV systems.
2.4 Environmental Standards
Schedule 9 of the Electricity Act 1989 requires SEPD to consider the effect of its work on the amenity and fisheries and to mitigate the effects where reasonable.
In planning, designing and operating the distribution system our policy is to pay due regard to environmental matters and, in particular, noise, visual amenity and pollution. We seek Planning Authority and Department of Trade and Industry approval to build new lines. We also endeavour to meet the requirements of other bodies, such as Natural England and the Environmental Agency, in protected areas such as Areas of Outstanding Natural Beauty. We will seek to avoid disturbance or detriment to such areas as far as reasonably practicable consistent with the economic and reliability impact on our distribution network and on customers' costs.
2.5 Company Internal Standards
In addition to meeting the above standards, SEPD has internal standards to improve quality of supply and reduce duration of supply interruptions.
2.5.1 General
The targets for duration of supply interruption, customer minutes lost (CMLs) per customer per year, and number of customer interruptions (CIs) are agreed with OFGEM. These standards are in addition to the Guaranteed Standards set by OFGEM.
In planning, designing and operating the distribution system the systematic use of automation, mobile generation and targeted investment for refurbishment of the distribution system is designed to deliver these targets.
To meet the individual needs of customers, we will agree standards of connection whether in excess or lower than the appropriate levels as stated in the relevant network standard. In these cases, we will agree special commercial terms.
2.5.2 Capacity Planning
To ensure that the distribution system has adequate capacity to meet system demand, voltage and current flows are regularly monitored and adequacy of the network is checked. Capacity is benchmarked to estimated loads. Where there is a shortfall in network capacity we will seek appropriate solutions. These will usually involve network reinforcement but could involve alternative solutions.
2.5.3 System Voltage Control
Page 12 SEPD May 2021 LTDS
The total full load volt drop for the transfer of power from the high voltage distribution system to the low voltage supply system is approximately 30%. Therefore, voltage correction must be applied in the appropriate places to comply with Regulation 27 of the Electricity Safety, Quality and Continuity Regulations 2002. This is carried out as follows: In higher voltage system by: Control of reactive power flows. This includes switching in or out lightly loaded circuits, shunt capacitors and reactors, use of synchronous compensators, operation of "tap-stagger" and use of voltage above or below nominal. Auto/manually controlled on-load tap changers on 400/132kV and 275/132 kV transformers). Central control by despatch of reactive power from synchronous generators. Automatic voltage control on synchronous generators. In the lower voltage systems by: Automatically controlled on-load tap changers fitted to 132/33 kV and 33/11 kV transformers; Line drop compensation on most 11 kV systems; Reactive compensation (shunt reactors and capacitors); Off load tap changers fitted to 33 kV/LV and 11 kV/LV transformers; Voltage regulators on the LV system.
3 DESIGN POLICIES
3.1 General
When planning and designing an electricity distribution system it is necessary to consider all alternative options to achieve an optimum solution based on technical and economical considerations.
The Company's distribution system has been standardised at 132 kV, 66 kV, 33 kV and 22 kV (called EHV), 11 kV and 6.6 kV (called HV) and 230/400 V (called LV).
Demand forecast methodology is formulated around a combination of important contributing factors impacting demand. Historic growth rates for each primary substation are calculated before being banded into four growth trends of Zero, Low, Medium or High. Individual future growth rates are based on the calculated historic trend and key drivers including committed connections, geographic economic factors derived from local authority development plans and demand forecast from large users with knowledge of major changes in connected load.
The key assumptions included in the demand forecast are as follows: The average cold spell (ACS) forecast assumed system peak demand is adjusted so the annual forecast references to a common temperature base. A
Page 13 SEPD May 2021 LTDS weighted average temperature, where ambient temperature is considered over a three-day period, is used in the calculation and appropriate adjustments are made to demand readings to produce the ACS values, which is what the demand would have been if the ambient temperature had been 0° C. The forecast includes contributions (power export) from embedded distributed generators (DG) running at the time of system peak. The projection includes an annual average of 8% contribution from DG. Consistent running arrangement and system configurations are considered. Recorded substation peak demands are normalised to account for abnormal running arrangement to ensure the forecast is consistent with previous years running arrangement. Individual demand forecast submissions from large consumers are factored into forecasts. Committed new loads and new connections are assumed to materialise in the manner predicted i.e. user timing and usage is assumed to occur as advised/requested by customer.
SEPD will undertake further assessments to determine whether intervention is required where the calculated planning fault levels, identified in Table 4, exceed 95% of the circuit breaker fault level rating. The additional assessments undertaken by SEPD include, but are not limited to, site specific protection settings analysis and circuit breaker trip testing.
If further assessments confirm that intervention is required SEPD will determine the most economic, efficient and cost-effective solution to reduce the overall fault level. Possible mitigation works include, but are not limited to, opening the bus-section circuit breaker, reconfiguring the network, installing fast response automation and extending circuit breaker trip times.
Fault level information is published for planning purposes only. It should not be used for operational purposes and does not necessarily reflect current operational circumstances.
3.2 132 and 33 kV System Design
132 kV and 33 kV networks from 400/132 kV and 132/33 kV substations (or equivalent 66 kV and 22 kV networks) normally run either radially or as open or closed rings. However, some networks run in parallel with those from other sources where technically acceptable and economically advantageous.
Additions to or reinforcements of these networks are considered individually and tailored to the existing network arrangements. The most economic investment is determined in line with any long-term proposals and having regard to network complexity, operational requirements and flexibility.
Studies are completed to ensure acceptable voltage conditions, compliance with security of supply standards for first and second circuit outages in accordance with
Page 14 SEPD May 2021 LTDS Engineering Recommendation P2/7 and that circuit and plant ratings are not exceeded.
Additionally, for generation, studies are completed to identify any locations where increased fault currents exceed switchgear ratings. For larger sets, or where there is likely to be interaction with existing customers with large motor drives, steady state and transient stability studies are needed to: Ensure generation and the networks remain stable following circuit switching or a network fault. Check interaction with other nearby generation. Predict any possible loss of synchronism and the corresponding need for additional protection to avoid damage to the generator or unacceptable voltage or power swings.
3.3 Supplies from Primary (typically 33/11 kV) Substation
The maximum number of 11 kV circuits from a 33/11 kV substation is determined on the basis of network configuration and maximum utilisation, e.g. for a substation with 2 x 15/30 MVA transformer capacity, the normal maximum number of 11 kV feeders would be 8.
Interconnecting feeders, where practical, would emanate from separate sections of busbar consistent with minimising initial switchgear requirements and allowing for future extensions.
New feeders will be controlled by automatic circuit breakers of 630 A nominal load rating.
3.4 HV Network Configurations
The HV network is normally configured to achieve maximum utilisation whilst maintaining security of supply standards at a minimum cost.
The HV urban network is normally configured as a "loop-tee-loop" arrangement in an open "ring" formation. However, where an individual customer requires more or less security of supply standard, then the connection to that customer will be designed to meet specific needs.
The HV rural network is normally configured as an open "ring" with pole mounted HV/LV transformers directly connected. However, where group demand is below 1 MVA the network configuration may be radial feed with no backfeed facility. Furthermore, there may be lengthy spurs (single and three phase), in particularly remote locations, served by overhead line circuits.
3.5 Low Voltage Network Configuration
The feeding arrangement on the low voltage network is normally radial with no interconnection. There is existing interconnected LV network which operates as radial
Page 15 SEPD May 2021 LTDS and is configured as an "open" ring. The layout of distributors is optimised in relation to services to be supplied. Distributors are normally laid in footways.
4 NETWORK CHARACTERISTICS

4.1.4 Telecontrol Normally all 22 kV or higher voltage switchgear is equipped with telecontrol. Use of telecontrol at 11 kV is considered according to the situation and location.
4.1.5 Batteries SEPD will normally provide its own battery systems for substation protection and control equipment where needed. However, shared use is considered if appropriate.
4.2 Power Quality
4.2.1 Harmonics Engineering Recommendation G5/5 sets the planning levels for harmonic voltage distortion to be used for the connection of non-linear equipment. These levels should not normally be exceeded when considering the connection of non-linear loads and generating plant to the distribution networks under the Distribution Code. The table below gives a summary of Total Harmonic Distortion (THD) planning levels:
System Voltage at point of common THD Limit coupling LV ( 400 V) 5% HV (< 20 kV) 4% EHV (< 400 kV) 3%
The assessment procedure for non-linear equipment uses three stages:
Page 17 SEPD May 2021 LTDS Stage 1 – connection of equipment of limited size to LV networks without individual assessment. Stage 2 – connection of larger equipment than the maximum in Stage 1 to all systems less than 33 kV. Measurements may be necessary. Predicted levels need to be less than specified levels. Stage 3 – connection at 33 kV and above or loads not acceptable under Stage 2. Measurement of existing harmonic distortion will be necessary.
The objective is to balance the degree of detail with degree of risk that the connection of the particular equipment will result on the supply system.
4.2.2 Voltage Fluctuations Engineering Recommendation P28 sets the planning limits of voltage fluctuations caused by industrial, commercial and domestic equipment. Allowable limits vary with the interval between fluctuations and are based on the likelihood of customer complaints. Normally acceptable values are 3 % and below.
4.2.3 Unbalance Engineering Recommendation P29 sets the limits of voltage unbalance on networks up to 132 kV. Normally acceptable values are 2 % and below.
4.2.4 Investigations There are no areas in SEPD where harmonic levels, voltage fluctuations or unbalance are known to be an issue. However, we will investigate and take measurements in response to customer requests. If the harmonic level is found to be unacceptable, we will seek an appropriate solution.
4.3 Method of Earthing
4.3.1 132 kV systems These systems normally use multiple direct neutral point earthing.
4.3.2 High Voltage System The methods currently employed to earth the neutral of High Voltage networks at EHV/EHV and EHV/HV substations are: Direct Earthing The only impedance between the transformer lower voltage winding star point (neutral) and earth consists of the earthing conductor and the resistance between the earth mat and earth. Resistance Earthing Use is made of an earthing resistor between the transformer lower voltage winding star point (neutral) and earth to limit the earth fault current. Earthing Transformers In instances where the transformer lower voltage winding is delta connected a neutral point is derived artificially by inclusion of an earthing transformer. This neutral point is then appropriately earthed.
Page 18 SEPD May 2021 LTDS 4.3.3 Distribution Substations Earthing is provided for HV metal work, LV neutral and extraneous metal work not associated with the power system e.g. fences etc.
Where the overall resistance to earth does not exceed 1 ohm the HV metal work, LV neutral earth and fence metal work (within 2 metres of HV metal work) are combined together. Where the overall resistance to earth exceeds 1 ohm HV metal work earth, LV neutral and fence metal work earths are kept separate and resistance to earth of each separate earth electrode must not exceed 40 ohms.
4.3.4 Low Voltage System The method applied to earth the LV system of most new networks and many existing networks is Protective Multiple Earthing (PME). This refers to the use of the supply neutral conductor of the LV network to provide earthing facilities for customers. There is also use of Continuous Earth Wire, Separate Neutral and Earth and Protective Neutral Bonding systems.
The general requirements that must be fulfilled are: The supply neutral conductor will be connected to an earth electrode at or near the transformer star point. The supply neutral conductor will not contain a fusible cutout, circuit breaker or switch. The value of the transformer neutral earth electrode will not exceed 40 ohms. The overall resistance to earth of the supply neutral conductor will not exceed 20 ohms.
In addition to the neutral earth at or near the transformer star point, the supply neutral conductor will be connected to other points either to earth electrodes or supply neutral conductor of another distributing main.
4.4 Protection Systems
4.4.1 General Protection equipment is used to recognise, locate and initiate removal of a fault or abnormal condition from the power system, normally by operation of a switching device. Circuit breakers and relays are normally used at higher voltages, but fuses are employed where relays are not economically justified.
To avoid unnecessary damage to plant and equipment and to minimise disconnection of healthy plant, it is essential that the protection systems employed on the distribution system are reliable, selective, fast and sensitive.
4.4.2 LV Feeders In most cases low voltage feeders are protected by fuses. These provide short circuit protection to the main feeder and connected services. The fuses are rated to provide discrimination with HV protection.
4.4.3 11 kV/LV Transformers (Ground Mounted)
Page 19 SEPD May 2021 LTDS Ground mounted 11 kV / LV transformers are normally protected by HV fuse switches. The fuses provide protection for faults on the HV cable to the transformer, faults within the transformer and faults on the LV connections.
4.4.4 11 kV/LV Transformers (Pole Mounted) Pole mounted 11 kV / LV transformers receive protection from either feeder circuit breaker, pole mounted auto reclosers / sectionalisers or pole mounted HV fuses.
4.4.5 11 kV Feeders 11 kV feeders are normally protected by circuit breakers with the following protections and typical clearance times: Predominantly underground circuits: IDMT overcurrent and earth fault protection - up to 1 s, but possibly up to 3 s depending on fault type and location. Predominantly overhead line circuits: Instantaneous high set overcurrent - 150 ms. Time delayed overcurrent and earth fault - 400 ms. IDMT overcurrent and earth fault - 50 ms – 3 s Time delayed sensitive earth fault - 7 s. Auto-reclosing as para. 4.6
Additional pole mounted auto reclosers are strategically located on the overhead network to limit the number of supply interruptions to customers for transient and permanent faults.
4.4.6 33/11 kV Transformers 33/11 kV transformers typically have the following protection and clearance times: High set overcurrent, instantaneous earth fault and restricted earth fault – 150 ms. 3 stage standby earth fault - 1.4 s, 2.1 s and 2.9 s. IDMT overcurrent and earth fault - up to 3 s. Neutral voltage displacement protection - 3 – 10 s. Buchholz and winding / oil temperature relays. Intertripping or fault throwing switch if needed to trip remote circuit breaker – 300 ms or operating time of remote protection.
4.4.7 33 kV Feeders and Transformer Feeders 33 kV feeders are normally protected by circuit breakers fitted with protection dependent upon feeder type (overhead or underground cable). Typical protection provided (and clearance time) is a selection from: Unit protection - 150 ms. Distance protection - 150 ms zone 1, 500 ms zone 2, 1.3 s zone 3. IDMT overcurrent and earth fault - up to 3s.
Page 20 SEPD May 2021 LTDS Auto-reclosing as para. 4.6 for predominately overhead circuits.
Additional protection is needed if remote transformers are connected, typically: High set overcurrent - 150 ms. Instantaneous earth fault - 150 ms. Intertripping over pilot cable or fault throwing switch.
4.4.8 132/33 kV Transformers 132/33 kV transformers typically have the following protection and clearance times: Overall biased differential, high set overcurrent, instantaneous earth fault and restricted earth fault protections - 150 ms. 3 stage standby earth fault protection - up to several seconds. Buchholz and winding / oil temperature relays. Intertripping or fault throwing switch if needed to trip remote circuit breaker - 300 ms.
4.4.9 132 and 66 kV Busbars 132 and 66 kV busbars are normally protected by busbar protection to provide discrimination and to isolate the faulted section of busbar. Typical clearance time is 150 ms.
4.4.10 132 and 66 kV Feeders and Transformer Feeders 132 and 66 kV feeders are normally protected by circuit breakers fitted with protection dependent upon feeder type (overhead or underground cable). Typical protection provided and clearance times are: A single main protection, either unit protection - 150 ms, or distance protection - 150 ms zone 1 or 500 ms zone 2. Additionally, if a transformer is remotely connected: High set overcurrent - 150 ms. High set earth fault - 150 ms. Intertripping may be installed. Back up protection to cater for failure of the main protection, normally IDMT overcurrent and earth fault - 1.1 s and 1.2 s, or distance protection zone 3 - 0.9 s. Auto-reclosing as para. 4.6 for predominately overhead circuits.
4.5 Network Automation In order to minimise customer minutes lost and customer interruptions due to outages, where economically viable, opportunity is taken to automate the HV distribution system by installing in-line circuit breakers or actuators.
4.6 Auto Reclosers The majority of faults on overhead lines are of transient nature (e.g. insulator flash over) generally caused by wind borne materials. These faults are normally cleared by opening of the source circuit breaker or pole mounted recloser and do not recur when reclosed. Auto-reclosing is therefore applied to most predominantly overhead circuits.
Page 21 SEPD May 2021 LTDS
Typical or preferred settings, where relays permit, are: 11 kV source circuit breaker: Trip 1 - Instantaneous high set overcurrent or time delayed overcurrent or earth fault or sensitive earth fault. 10 s dead time. Trip 2 - IDMT overcurrent or earth fault or time delayed sensitive earth fault. 90 - 120 s dead time (or lock-out if sensitive earth fault). Trip 3 - IDMT overcurrent or earth fault to lock-out. Reclaim time 5 s. 11 kV pole-mounted circuit breakers: Settings to co-ordinate with the above. Final dead time 90 or 120 s. 33 kV circuit: Single shot. 90 s dead time. 5 s reclaim time. 132 kV circuit Single shot. 15 s dead time. 5 s reclaim time.
4.7 Operating Voltages The company's distribution system operates at nominal voltages such as 132, 66, 33, 22, 11, 6.6 kV and 230/400 V.
4.7.1 General Voltage control is applied at various voltage levels to ensure that statutory levels are maintained at customers' supply terminals as below.
4.7.2 Voltage Control of HV (11 and 6.6 kV) and LV system Automatic control of the 11 kV source voltage is obtained by the on-load tapchanger on the 132/11, 66/11 and 33/11 kV transformers. The interval between taps is typically 1.25% or 1.43%.
Line drop compensation is normally applied to rural 33/11 kV transformer tapchanger control schemes to arrange an automatic increase in the 11 kV source voltage with increase in demand. Typical settings are 1.05 p.u. at full load and 0.985 p.u. at no load. The 11 kV system is typically designed to accommodate 6% volt drop.
The low voltage system is typically designed so that the aggregate volt drop in the low voltage distributor and service does not exceed 7% with normally less than 2% in the service.
Page 22 SEPD May 2021 LTDS
4.7.3 Voltage Control of EHV (33 and 22 kV) System The voltage at the 33 kV source is set to the highest permissible value, typically 1.03 p.u., in order to permit maximum design volt drop in the 33 kV system. It is also chosen to ensure that the required 11 kV and LV busbar voltages at both nearby and remote substations can be achieved.
4.7.4 Voltage Control of 132 kV System The 132 kV voltage at a 400/132 kV Grid Supply Point is maintained by National Grid plc at a mutually agreed level and is usually between 1.00 and 1.05 p.u. Each part of the system is studied in detail taking in to account normal and abnormal conditions, circuit configuration, tap ranges, impedances, demand and voltage required at the 33 kV busbars.
4.8 Generation Connection Policy The principal duty placed on the Authority is to protect the interest of consumers having regard to the need to secure that all reasonable demands for electricity are met. This duty is devolved to the licensee to develop the distribution systems in an economical manner whilst maintaining defined planning standards. The implications are that whereas demand for electricity must be met year-round, generators will not always be able to simultaneously generate at their authorised capacity since the supply and demand for electricity must be balanced at all times. Therefore, it is necessary that, before any offer for connection is made, detailed network analysis is carried out to ascertain the impact of generation so that the quality of supply to connected consumers is not compromised.
Generators connected to the LV, HV or EHV distribution system must comply with the general principles specified in Engineering Recommendation G99 and associated Engineering Technical Report no.113 or G98 as applicable. Where appropriate, the requirements of the Distribution Code and Grid Code must be met.
It is a requirement that Neutral Voltage Displacement will be fitted to all generators where the size of the generator or group of generators on the same connection point exceeds 200kVA. This is to ensure that the risks of back-energising the 11kV network from an LV generator is small.
4.9 Load Management Areas In compliance with the Grid Code and on receipt of instructions from NGC, voltage reduction may be applied to reduce demand and maintain system frequency. There are no load management areas in SEPD.
4.10 Network Constraints and Opportunities There are constraint areas for accepting new generation or load. However, background fault levels at most voltages are generally high. This is due to a higher fault infeed from the 400 kV transmission system and the lower impedance of the distribution system.
There is currently about 3380 MW of embedded generation connected to the distribution system at various voltages across the whole area served by SEPD.
Page 23 SEPD May 2021 LTDS Approximately 500 MW is concentrated around the areas supplied by Fawley and Nursling 400/132kV substations.
The continued growth in generation connecting at distribution voltages is driving ongoing improvements in how SEPD seeks to provide information and assistance to customers wishing to connect to its network.
The current trend of growth in generation connections has reinforced the importance of SEPD continuing to develop and recognise its responsibility to provide information and assistance. This is coupled with the ongoing need for strong customer interaction and support to potential distributed generation customers.
It is essential that prospective generation developers work with SEPD to ensure correctly located and well-matched generation is incorporated into its network to the mutual benefit of both customers and SEPD.
Key areas that need to be discussed and monitored are the impacts of the generation on the network and the impacts of the network on the generation.
The addition of generation to the network impacts the system fault levels, which in turn can lead to network reinforcement works being necessary to support the connection. The power flows experienced by the modified network, if not accurately analysed, monitored and controlled, could cause system overload, over and under voltage, system frequency variations and reduce system power factors. All of these are undesirable on the distribution network. All are points that must be considered when designing and developing a generation connection.
Networks may well have to be redesigned in order to best adapt to the generation connection requirement. This will add both cost and time to the connection project and should be considered and remembered when submitting any such connection enquiry or request. There are benefits to the network. Connection of well sited and adaptable generation could provide network support and reduce network losses. The development must supplement SEPD’s responsibility to deliver a safe, secure and reliable network and be in keeping with our ethos to “deliver energy in a safe and sustainable way”.
When considering connecting new load or generation to the network, it must be thoroughly planned and designed to meet the requirements set out in the Distribution Code, and in line with the information contained within this LTDS document.
Depending upon connection size and type, an application may need to be made to National Grid for a “Statement of Works” OR “Modification Application”. This can be discussed at the point of request for information or during the initial scoping of any connection enquiry. There may be charges associated with these applications.
The following short guide may assist users who wish to complete initial investigations and assessments of proposed connections to SEPD’s network.
Key Milestones in the investigation process.
Page 24 SEPD May 2021 LTDS Fill out a generation connection form, available from the ENA Resource Library website and submit this to SSEN:
https://www.energynetworks.org/industry-hub/resource-library/
This will commence dialog with the company in relation to the connection request. Identify your new Connection, Generation or Load. State the capacity and type of generation to connect; Wind, Solar, Hydro, combined Heat and Power systems, Bio-mass or other. Unless a specific location is required, select an area on the LTDS geographic map or select a substation local to the desired connection area. Using the information available in the LTDS investigate that the selected substation’s capacity, demand, forecast demand and fault level could support the new connection. Collect technical data from LTDS and perform self study o Carry out study of the impact of new generation on the existing network parameters including; o Fault level contribution of connecting new generator o Clean or dirty load giving rise to System harmonics o Impedance of the unit, how will this alter fault level? o What is the effect under 1st circuit outage conditions?
Connection charges will vary with the location and size of the proposed connection. At the point of connection request or enquiry, costings will be advised in line with the Southern Electric Power Distribution Statement of Methodology and Charges for Connection to Southern Electric Power Distribution’ Electricity Distribution System. http://www.ssen.co.uk/Library/ChargingStatements/SEPD/
Applications for connection of generation are evaluated on an individual basis. Information on generation connections and applications can be found in Table 5 and Table 6 of this statement’s data section which summarises larger embedded generation installations in SEPD’s area.

8.2 Network Data
8.2.1 Circuit Data The electrical parameters for EHV circuits are shown in Table 1 of this statement’s data section. Circuit rating information relates to the main item i.e. cable or overhead line and is based on the smallest cross section. Cyclic ratings are given where
Page 28 SEPD May 2021 LTDS appropriate. In practice other items such as current transformers, protection equipment and isolators may restrict the circuit rating. The information is intended to illustrate the basic circuit capability. The vast majority of circuits operate at their construction voltage.
8.2.2 Transformer Data EHV/EHV and EHV/HV transformer data is shown in Table 2. A site-specific analysis can be carried out to ascertain the reverse power capability of each transformer.
8.2.3 Demand Data The maximum demand recorded at the substation during the previous twelve months is shown in MVA and power factor in Table 3. The forecast demand is normally based on the historical growth trend plus any large known development. Firm capacity for multiple transformer sites relates to the remaining capacity under n-1 (largest unit loss), although higher loads can often be supplied by using load transfers or mobile or local generation. Note that limitations in the higher voltage network may restrict spare capacity. For single transformer sites the demand will normally be secured by use of interconnection, mobile generation or combination of both.
The minimum load scaling factor is the ratio of minimum to maximum demand. Appendix 2 shows typical substation load profiles.
8.2.4 Fault Level Data Calculated three phase fault level (plus single phase fault levels for 132 kV) data under normal running arrangements is shown in Table 4A (132 kV) and Table 4B (6.6, 11, 22, 33 and 66 kV). Normally there will be more than one circuit breaker at a substation site; the make and break ratings shown relate to the existing circuit breakers. At most sites, not all circuit breakers would be subject to the fault currents given.
Fault currents given include contributions from all transmission and distribution networks and generation included in our study model. The break current will be dependent on the break time. Break current values given in this statement are decremented RMS values at 50 ms. This decay time is a conservative assumption and may vary for some sites. Make values include contributions from induction motors as per Engineering Recommendation G74. Normally break and make fault currents will not be allowed to exceed switchgear ratings.
8.2.5 Connected Generation Table 5 details the substation and connection voltage of various types of generation connected to the network. All listed units are greater than 1 MW generation capacity.
8.2.6 Interest in a connection Table 6 details the recent interest in connection of various load and generation connections by substation. The table presents the number of formal and budget enquiries, the number of accepted applications and the total cumulative capacity of all applications.
8.2.7 Busbar and node codes
Page 29 SEPD May 2021 LTDS Table 7 details the busbar and node codes used in the Tables. There are also diagrams that show how the various busbars interconnect. These can be found separately on the Long Term Development Statement webpage.
8.3 Other Information
Additional information is available on request: Circuits e.g. zero sequence impedance. Transformers e.g. earthing details, hot sites. Demand e.g. limitation on firm capacity, demand duration profiles. Fault Level e.g. contributions to fault current at each node, decremented break fault currents, details of limitations and indicative cost to relieve.
