Node Assignment Ruleset

The System Operators are undertaking a review of the Node Assignment Ruleset that was in place during the Gate 3 and ECP-1 process. The objective of this review is to streamline the rules and enhance the efficiency of batch processing in ECP-2 whilst also providing more clarity to applicants.

Parallel Generators

For information on Connecting a generator that operates in parallel with the electricity network please see here. This information is relevant to businesses that want to reduce their electricity import by having their own source of power, or for peak-lopping or peak-shaving schemes. Such generators cannot be used to supply or sell electricity via the national grid.


Interface Protection Guidelines

These slides (PDF | 171 KB) outlining guidelines for costs and applicability of Embedded Generation Interface Protection (EGIP) were presented at the CRU Gate 3 Liaison Group meeting as a clarification and update of the Conditions Governing document in June 2013.

Standby Generators

Information about connecting a standby generator is available here. Standby generators are used by businesses that require emergency generation. They cannot be used to export or sell electricity onto the electricity network. In addition, they cannot operate in parallel with the electricity network.


Micro-generation is the term which applies when a private individual (e.g. a householder) installs a small generator on his/her property for the purpose of producing electricity for his/her own use. See here for more information on connecting a  micro-generator
