  5. Agenda EREC G99 EREC G99 Changes to Terminology Documents & Forms Connection Process Roles & Questions & Connection timeline Responsibilities under EREC G99 Answers

  6. EREC G98 and EREC G99 G98: G99: Requirements for the connection of Fully Type Tested Requirements for the connection of generation Micro-generators (up to and including 16 A per phase) equipment in parallel with public distribution in parallel with public Low Voltage Distribution networks on or after 27 April 2019 Networks on or after 27 April 2019 6

  7. EREC G99 Terminology 7

  8. EREC G99 - Types (GB) • Types affect technical requirements and which forms you use Type A Type B Type C Type D <110 kV <110 kV <110 kV >110 kV Power Generating 0 800W 1 MW 10 MW 50 MW Module Registered Capacity 8

  9. EREC G99 - Power Generating Units & Power Generating Modules SYNCHRONOUS SCHEME ASYNCHRONOUS SCHEME Types depend 9 on PGF PGF PGM capacity PGM PGM PGM definition PGM GU PGM depends on GU GU whether the PGM GU technology is synchronous / asynchronous Generating Unit, GU Power Generating Module, PGM Power Generating Facility, PGF

  10. EREC G99 – Type A synchronous machine example 3 x 400 kW Type A Synchronous PGMs = 1.2 MW PGF Connection Power Generating Module Point (CP) 400 kW (PGM) / Synchronous Power Generating Module 400 kW Power Generating Facility (PGF) 400 kW 10

  11. EREC G99 – Type B asynchronous example 1 x 400 kW Inverter connected plus 2 x 400 kW Asynchronous GU = 1.2 MW Type B PPM = 1.2 MW PGF Power Generating Module (PGM) / Power Park Module CP 400 kW (PPM) DFIG 400 kW Power Generating Facility (PGF) DFIG 400 kW 11

  12. EREC G99 – Synchronous and Asynchronous Type B Power Generating Modules in same Power Generating Facility 3 x 4MW Type B synchronous PGMs 2 x 500 kW Inverter connected plus 1 x 500 kW Asynchronous GU = 1.5 MW Type B PPM 1 x 1MW Energy Storage = 1MW Type B PGM = 14.5MW PGF Power Generating Module (PGM) / Synchronous Power Generating Module Power Generating Module (PGM) / Power Park Module (PPM) Power Generating Facility (PGF) 12

  13. EREC G99 Documents & Forms 13

  14. EREC G99 – Standard Application Form, SAF Used when wanting to connect a Power Generating Module greater than 16 Amps per phase. Changes include:- • Alignment of terminology with G99 (PGM, GU etc) • Inclusion of storage data • New technical data • Voltage control data • Frequency response droop settings • Type C & D only: • Governor and prime mover model • AVR and excitation model • Short circuit ratio Can be accessed from our website: https://www.enwl.co.uk/get- connected/new-connection/generation-connection/over-200kw/

  15. EREC G99 – Power Generating Module Document, PGMD = Compliance Statement Type B – form B2-1 (appendix B of EREC G99) Type C & D – form C2-1 (appendix C of EREC G99)

  16. EREC G99 – Operational Notifications, ION, EON, FON Notifications issued by the DNO to a Generator Final Operational Notification (FON) Types B,C&D: Issued when the relevant requirements of EREC G99 are complied with allowing operation of the PGM in parallel with the distribution network. Limited Operational Notification (FON) Type D only: Issued to a generator who had previously attained FON status but is temporarily not fully compliant Energisation Operational Notification (EON) Type D only: Issued prior to energisation of a generator’s internal network. Interim Operational Notification (ION) Type D only: Issued to permit time limited synchronisation when there are outstanding compliance issues.

  17. EREC G99 – Manufactures Information Manufacturers’ Information is the generic term for information that the Generator needs. It can include type testing information, but also other relevant information that does not necessarily come from type tests, e.g. simulation studies etc. The information is supplied by the manufacturer to the customer, who should send it to the DNO. The suitability of the information is agreed between the generator and the DNO – although a three way discussion involving the manufacturer might well be appropriate in some cases. A manufacturer might have posted this information on the ENA database , in which case it will have an ID reference. The generator can use the ID reference in compliance forms.

  18. Changes to the connection process 18

  19. EREC G99 - Who is EREC G99 applicable to? Applies to:- New generator connections >800W Electricity Storage, but some technical requirements do not apply All types of electrical conversion machines and equipment Generators significantly revised or replaced after 27 April 2019 Exempt:- Generators connected before 27 April 2019 Plant procured before May ‘18 and notified to DNO before Nov. ‘18

  20. EREC G99 - What part of the connection process is changing? Now After 27 April 2019 From Generator Concept to Connection Information Phase Information Phase Design Phase Design Phase Connection Offer Connection Offer Connection Acceptance Connection Acceptance Compliance Checking Compliance Checking Construction Phase Construction Phase Energisation/Commissioning Energisation/Commissioning Final Compliance Check Operational Notifications

  21. EREC G99 Connection Process - Design Phase Connection Process Design Phase Design Phase Information Phase G99 Documents Design Phase Modified Activities Connection Offer Connection Acceptance • Standard Application  Generator submits SAF Compliance Checking Form Construction Phase Energisation/Commissioning Final Compliance Check Operational Notifications Timeline Offer issued after submission in accordance with GSOP timescales

  22. EREC G99 Connection Process Design Phase – Submission of SAF • Form A1-1 for Type A fully type tested <50kW 3-phase (17kW 1-phase) • SAF >50kW 3-phase • Different parts submitted at different times • Different parts for different technologies Part 1 Contact details, location and operational information Part 1a Supplementary contact details Initial Submission Part 2 Power Generating Facility general data Part 3 Power Generating Module model data Part 4a Synchronous Power Generating Modules Part 4b Power Park Module model data: Fixed speed induction Generating Units Part 4c Power Park Module model data: Doubly fed induction Generating Units Part 4d Power Park Module model data: Series inverter connected Generating Units Part 4e Power Park Module model data: Electricity Storage plant Part 4f Transformer information Prior to Synchronising Part 5 Additional data which may be required by the DNO

  23. EREC G99 Connection Process - Compliance Checking Connection Process Compliance Compliance Information Phase Checking Design Phase Checking Connection Offer Documents Activities Connection Acceptance  Generator & DNO Compliance Checking • Power Generating agree compliance Construction Phase Module Document submission programme Energisation/Commissioning Final Compliance Check  Generator iteratively • Generator’s compliance Operational Notifications submits their PGMD & evidence Timeline associated evidence (Simulation reports, From time of acceptance  DNO reviews & Manufacturers Information, to prior to energisation Type Testing reports) responds / repeat

  24. EREC G99 Connection Process - Compliance Checking Technical requirements Generators can choose vary with Type how they demonstrate compliance Compliance is tracked in Incl. manufacturer info, the PGMD type testing, simulation and site commissioning tests DNO approval is required

  25. EREC G99 Connection Process Compliance Checking – use of the PGMD • Record of compliance evidence • PGMD is likely to be iterative as the generator submits evidence of compliance and the DNO reviews it. Page 1 PGM and DNO basic information General information Page 2 PGMD version control / PGM details Pages 3 – 7 Synchronous Power Generating Module compliance requirements Part 1 for Synchronous Pages 3-4 submitted at Initial Submission Pages 5-7 submitted at FONs – post energisation verification test documents Pages 8 – 12 Power Park Module compliance requirements Part 2 for Asynchronous Pages 8-10 submitted at Initial Submission Pages 11-12 submitted at FONs – post energisation verification test documents

  26. EREC G99 Connection Process - Energisation/Commissioning Connection Process Energisation / Energisation / Information Phase Design Phase Commissioning Commissioning Connection Offer Activities Documents Connection Acceptance  Generator undertakes Compliance Checking • Commissioning forms site commissioning Construction Phase (A2-1, A2-2, A2-3, Energisation/Commissioning  DNO may witness tests Final Compliance Check B2-2 & C2-2) Operational Notifications including remaining • Installation forms Timeline compliance (A3-1, A3-2, B3 & C3) requirements Immediately before operation
