Welcome to the ENA's Accelerated Loss of Mains Change Programme (ALoMCP)

As part of the UK's energy transition, all owners of generating sites in Great Britain are required to ensure that their installations are compliant with Engineering Recommendation G59/3-7. Making these changes through the programme will help National Grid ESO operate the electricity network more efficiently, reduce balancing costs and therefore provide savings to electricity customers.

If your equipment is already compliant, please confirm by submitting a declaration; if not, please apply for funding to help you make the changes by the deadline of 1 September 2022.

Submit a compliance declaration

* Compliance declarations can be submitted without registering first, however registration is recommended because it allows access to view and amend declarations previously submitted and is particularly advisable for anyone intending to submit more than one declaration as it will reduce data entry. You must register before applying for funding.

Registered generation owners or agents making funding applications on their behalf can login here. Unregistered owners or agents can register here.

This section of the site is oriented towards submitting declarations of compliance to the latest version of Engineering Recommendation G59 for installations that are, or may be, already compliant. Please click here to switch to the area of the site geared towards submitting an application for funding to make the necessary changes to achieve compliance.

If you are intending to declare multiple sites, and particularly if acting as an agent for multiple owners, please read the guidance here.

If you experience any problems or issues with the declaration or application process or have any comments or suggestions for improvements, please let us know via our feedback page. We aim to respond to any feedback within 24 hours.
