New requirements have been made in the Distribution Code EREC G59 and all owners of generation sites must make these Loss of Mains changes by 31 August 2022 regardless. 

By making them in the Accelerated Loss of Mains Change Programme (ALoMCP), you can could take advantage of financial support and expertise to carry out the work.

Since the ALoMCP launched in September 2019, many sites have been updated to meet the new code requirements.

We’ve made good progress but more changes need to be made rapidly to reduce increased Loss of Mains costs.

Making these changes through the programme will help us run the grid more efficiently and reduce network costs.

More funding is available and we’re keen to receive applications from owners of generation sites.

The fast track application process offers an additional payment of £5000 to distributed generation sites that meet specific qualifying criteria and can commit to making required Loss of Mains protection changes quickly.

The new process, which launched on 29 June 2020, will run in ‘schemes’. Each scheme will have its own qualifying criteria, cap, and additional payment.

Sites that meet the criteria can apply on the registration portal.

For more information, please read the Payment Process Specification or contact your DNO/IDNO.

Sites that meet the fast track criteria are encouraged to apply on the registration portal:

• Minimum site capacity: 500 kW
• Maximum site capacity: Less than 5,000 kW
• Type of LoM protection: RoCoF
• Pre-change RoCoF settings: Up to and including 0.2 Hz/s
• Lead time to completing the changes: Less than or equal to 4 weeks

Applying for the Accelerated Loss of Mains Change Programme is easy.

Step 1

Check if your generation site needs to make the Loss of Mains changes.

Note: This programme does not apply to domestic and similar generation that has been connected under EREC G83. It only applies to generation connected before 01 February 2018 in accordance with EREC G59.

To apply to the fast track process, make sure your site meets the specific qualifying criteria.

Step 2

Head over to the registration portal on the ENA website. We’ll be using this to assess all applications.

Since the Accelerated Loss of Mains Change Programme (ALoMCP) launched in September 2019, we've helped many sites to make the changes to meet the new code requirements.
