What are the changes to Loss of Mains protection?
New requirements have been made in EREC G59 in the Distribution Code. All owners of generation sites must ensure their compliance with the revised Loss of Mains protection requirements changes by 01 September 2022.
The Accelerated Loss of Mains Change Programme (ALoMCP) offered funding for applications received no later than 10 May 2022 for non-domestic distributed generators that were connected before 1 February 2018 to upgrade their hardware in a move that will improve network resilience, and support wider initiatives helping meet the UK’s net zero targets.
Applications for funding are now closed, but all applicable generators will be required by the Distribution Code to have up to date protection settings by 1 September 2022 or they could be the subject of an enforcement process. Generators are encouraged to contact their Distribution Network Operator without delay to provide details of their compliance if they have not yet done so.
Generators can access further guidance and contact details for the Distribution Network Operators and Independent Network Operators via an online portal hosted by the Energy Networks Association.
Information for successful applications received no later than 10 May 2022
Since the ALoMCP launched in September 2019, many sites have been updated to meet the new code requirements..
For generators who have been successful in securing funding through ALoMCP, the amount of funding available for each site's changes is reducing:
Sites completing the changes after 24 March 2022 but on or before 23 June 2022 will be paid 80% of values within Table 2 of the Payment Process Specification
Sites completing the changes after 23 June 2022 but on or before 31 August 2022 will be paid 70% of the values within Table 2 of the Payment Process Specification

Who’s driving the programme?
The ALoMCP was led by National Grid ESO, the Energy Networks Association, Distribution Network Operators (DNOs) and Independent Distribution Network Operators (IDNOs).
The programme Steering Group ensured that the views of key stakeholders were considered in the overall management of the programme as well its delivery by network licensees. It made sure that the ALoMCP was run efficiently and for the benefit of stakeholders and consumers.
