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 ensure you make the changes by the deadline of 1 September 2022. You can find more information on how to achieve compliance here.

Submit a compliance declaration

Submit without Registering *     Register and Submit
Apply for funding

The latest date to apply for funding was 10 May 2022

* 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.

Registered generation owners or agents making compliance declarations on their behalf can login here. Unregistered owners or agents can register here.

This site is now oriented towards submitting declarations of compliance to the latest version of Engineering Recommendation G59 for installations that are, or may be, already compliant. The deadline for submitting new applications for funding was 10th May 2022 but applications submitted prior to the deadline that are still being processed will still be available for ongoing processing to logged-in users via the menus and buttons available on this screen. You can also click here for more information, links and resources related to funding applications.

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.
