Accelerated Loss of Mains Change Programme

This programme has now closed for funding applications however, it remains a requirement for all owners and operators of generation sites in Great Britain to ensure their installations are compliant with the Loss of Mains protection regulations outlined in the G59 Distribution Code.  These recent changes are crucial to maintain a robust and reliable electricity network capable of supporting the energy transition to Net Zero and non-compliance could result in enforcement action being taken.

The mandatory compliance deadline for generation connected to the grid before February 2018, and of 11kW to 50MW capacity, was 1 September 2022. However, generation owners are still required to declare compliance status.

If you are unsure of whether your generation is compliant or if you need to make any changes, we’d encourage you to seek guidance from competent contractors who can assess your equipment, complete any works required and support your compliance declaration.

By futureproofing your equipment, you will ensure it is more efficient and improve the resilience of the grid, whilst supporting your community and the wider initiatives that are helping us to meet the UK’s zero carbon targets.
