Summary

The modifications made to the Distribution Code, and Engineering Recommendations G59, G83, G98, and G99 are to address a number of minor technical and housekeeping issues that have come to light as stakeholders start to apply G98 and G99 in advance of the compliance date of 27 April 2019. There are also a very small number of consequential changes to G59 and G83.

Impact

Impacts on Users of The Distribution Code
There are no new impacts on Users of DNOs’ systems.

Impacts on Total System and the DNOs System
There is no impact on the Total System nor on DNOs’ systems. Implementing these proposed modifications should remove ambiguity and ease the compliance process for both DNOs and users.

Summary

ENA EREP 130 is a guidance document for the EREC P2 planning standard and an Annex 2 document to the Distribution Code. The proposed modification of this document has been written to recognise the changes to the load and generation connected to distribution networks since ETR 130 Issue 1 was initially published in 2006. In particular it recognises that:

  • some demand customers are modifying their electricity consumption in response to market signals; this means that further consideration has to be given to establishing the true demand on the network;
  • in addition to providing security of supply from network assets and distributed generation, demand side services can also contribute to security of supplies;
  • the nature and type of distributed generation connected to the network mean that their contribution to security of supplies is different to that in EREC P2/6 and EREP 130 Issue 2; and
  • ER P2/6 has been revised and a new version EREC P2/7 has been proposed in Modification DCRP/MP/18/03.

Impact

Impacts on Users of The Distribution Code
The purpose of this revision is to provide clarity on the means of providing the security of supply at the level required by EREC P2/7. It is not expected to have material impact on Users, other than providing clarity on how the security contribution from Users equipment should be assessed.

Impacts on Total System and the DNOs System
The purpose of this revision is to provide clarity on the means of providing the security of supply at the level currently required by EREC P2/7. It is not expected to have material impact on the Total System or the DNOs Systems.

Environmental Impact Assessment
There are no environmental impacts associated with this proposed modification.

Summary

In February 2018, Ofgem published its consultation on the implications for licences and industry codes and where amendments may be required in advance of the UK’s exit from the EU. Initial analysis accompanying that consultation identified potential modifications needed to the Distribution Code and linked industry code provisions.

Subsequent analysis carried out by the Energy Networks Association (ENA) on behalf of the Panel has determined the proposed modifications needed to the Distribution Code, as well as associated documents including the Distribution Code Review Panel - Rules and Constitution and certain Qualifying Standards including ENA EREC G83, ENA EREC G98 and ENA EREC G99, in the event the UK leaves the EU without a deal.

The proposed modification affects a number of requirements, which reference the need for compliance with EU legislation. In the event the UK leaves the EU without a deal, certain EU legislation and future decisions of the European Commission and Agency for the Co-operation of Energy Regulators will cease to apply to the UK after exit day (29 March 2019).

The UK Government plans to introduce Statutory Instruments, by virtue of the European Union (Withdrawal) Act 2018, to ensure legislation (of both UK and EU origin) governing the UK’s energy networks is effective in this event. As such, certain EU legislation and aspects of it, will continue to form part of UK legislation after exit day. This is termed “retained EU law” and has the meaning attributed to it in section 6(7) of the European Union (Withdrawal) Act 2018 and includes any modifications to UK legislation made under the Section 8 of the of the European Union (Withdrawal) Act 2018 to address inoperabilities including but not limited to The Electricity and Gas Etc. (Amendment Etc.) (Eu Exit) Regulations 2019. The use of the term “retained EU law” in this proposed modification has the same meaning as that defined in the proposal for modification of the Distribution Licence.

The effect of the proposed modification to the legal text in the Distribution Code and the associated documents stated in this Report, which are under the governance of the Panel, is to ensure that retained EU law and provisions in relevant Statutory Instruments, that have been prepared under the European Union (Withdrawal) Act 2018, are correctly addressed in the event the UK leaves the EU without a deal.

Impact

Impacts on Users of The Distribution Code
This modification proposal is foreseen as having a low impact on Users of The Distribution Code and the associated documents stated in this Report given the intent is to align legal text with the proposed changes to the legal framework and not to change current obligations, duties, policies or technical requirements.

The changes in the legal text will be of particular interest to those Users that manufacturer, purchase, install and commission micro-generators and Power Generating Modules in accordance with the requirements of ENA EREC G98 and ENA EREC G99, as appropriate.

Impacts on Total System and the DNOs’ Systems
There is no foreseen impact on the Total System or the DNOs’ Systems associated with this proposed modification.

Impacts on Users of DNOs’ Systems
There are no foreseen impacts on Users of DNOs’ Systems.

Environmental Impact Assessment
There are no environmental impacts associated with this proposed modification.

Summary

Ofgem approved the implementation of the EU Network Code “Requirements for Generators” (RfG) on 15 May 2018 (with compliance required from 27 April 2019). The implementation consisted of parallel changes to the Grid and Distribution Codes, and the introduction of ERECs G98 and G99.

The modification which was implemented in GC0100 (EU Connection Codes GB Implementation Mod 1) recast the long-standing Grid Code fast fault current injection (FFCI) requirements in a way that was intended to be phrased so as to be compatible with the Requirements for Generators (RfG). Identical wording was used in both the Grid Code and EREC G99 to describe the FFCI requirements. However, the wording chosen by the GC0100 workgroup has proven to be open to misinterpretation and has induced some confusion amongst a number of stakeholders, particularly manufacturers.

Manufacturers of Power Park Modules need clarity on the FFCI requirements so that then can ensure compliance at the point of manufacture. It is not possible to test for compliance with the FFCI requirements on site, so it is crucially important that the requirements are specified with complete clarity and freedom from ambiguity.

Impact

Impacts on Users of The Distribution Code
There are no new impacts on Users of DNOs’ systems.

Impacts on Total System and the DNOs’ Systems
There is no impact on the Total System nor on DNOs’ systems. Implementing these proposed modifications should remove ambiguity and ease the compliance process for both manufacturers and DNOs.

There are no impacts on other industry documents.

Environmental Impact Assessment
There are no environmental impacts associated with this proposed modification.
