Great British Energy has expanded its £300 million Supply Chain Fund for offshore wind and electricity networks, increasing the number of eligible critical components from 12 to 29.
The expansion opens capital grant opportunities for UK manufacturers producing equipment used across the two sectors. Round 4 of the fund is now open, with applications closing on 10 December 2026.
The 17 newly eligible components include offshore wind equipment such as jackets, generators, gearboxes and power converters. The electricity networks category now also covers high-voltage (HV) bushings, converter valves and components for HVDC converter stations and HVAC substations.
Great British Energy said the expanded list reflects updated market intelligence and evidence on components where supply constraints could affect the delivery of new clean energy infrastructure.
The fund is part of the organisation’s £1 billion Energy Engineered in the UK programme, which is intended to support investment in domestic clean energy supply chains and manufacturing capacity.
Rob Gilbert, interim director of supply chain at Great British Energy, said: “Building a strong UK clean energy industry means investing not just in major infrastructure, but in the manufacturers and specialist components that make it possible.”
The organisation has also introduced a process allowing manufacturers, trade bodies and other industry stakeholders to submit evidence for additional components to be considered for funding.
Great British Energy said the eligibility list will remain under review as market conditions and supply chain constraints change. Updated scheme guidance has also been published, including further information on grant intensity and evidence requirements.
The wider fund is intended to address supply constraints at different stages of the manufacturing chain as the UK expands offshore wind capacity and upgrades its electricity networks.
Gilbert said the expansion was “an important step” towards building domestic manufacturing capability and attracting investment into UK supply chains.
