National Grid Electricity Transmission (NGET) has agreed to pay £20m into Ofgem’s Energy Industry Voluntary Redress Scheme.

NGET accepted historic failures to properly monitor, maintain and repair some civil assets and to plan and resource remediation works on those civil assets at the Harker 132kV substation near Carlisle, Cumbria.

Harker serves customers in the Northwest, and there is embedded generation (including renewable generation) seeking to connect to the distribution network in the locality. The substation also connects to the 132kV transmission network in Scotland, making it part of the overall network capability across the Anglo-Scottish border.

NGET has already undertaken repairs to those civil assets at Harker in 2022 and acknowledged the failures, and will pay the Scheme, operated by the Energy Saving Trust, that uses the fund to distribute voluntary payments from companies to energy-related projects that support vulnerable consumers, drive innovation, and reduce carbon emissions across Great Britain. As of July 2025, the scheme has allocated £181m to 721 projects.
