The Accelerated Loss of Mains Change Programme (ALoMCP) is an industry-wide project taking place across Great Britain.

There is an obligation to be compliant by 31 August 2022. This means that all applicable generators installed prior to February 2018 must either alter Loss of Mains (LoM) settings on existing equipment or replace equipment.

To encourage generators to make the Loss of Mains settings change required, some funding is available for early adopters.

The programme is run by the National Grid, Distribution Network Operators (DNOs), Independent Distribution Network Operators (IDNOs) and the Energy Networks Association.

The purpose of the programme is to update LoM protection for renewable electricity generators, like wind turbines, hydro schemes, and solar PV, to reduce the risk of needless tripping and subsequent loss of generation/income. The approach taken to achieve this aim is to relax the RoCoF (rate-of-change-of-frequency) limits on the grid.

To apply for payment for implementing the LoM protection settings, applications must be sent via the application portal on the Energy Networks Association website.

You can apply at any time, however, applications submitted within each window are likely to be progressed together according to the timetables in the sections in Figure 2. The earlier a generator project applies, the more likely it is that funding will be secured – funding is not guaranteed. Read our resource to find out details of the funding windows.
