Great British Energy

What Great British Energy does

Great British Energy (GBE) is a wholly publicly owned energy investment and development company established by the UK Government under the Great British Energy Act 2025 (Royal Assent May 2025) and headquartered in Aberdeen, Scotland. The company was allocated £8.3bn in the 2025 Spending Review and operates alongside a £27.8bn National Wealth Fund co-investment facility, with the legal entity Great British Energy Group Limited (SC825539) domiciled in Scotland. GBE does not sell commercial products or services; instead it deploys public capital as equity, grants, and loans into UK clean energy projects across nuclear small modular reactors, offshore wind (including floating), onshore wind, solar PV, hydrogen electrolysers, and domestic supply chain manufacturing.

GBE's operating model is structured across four divisions: GBE Local (community and public sector solar/renewables, including installations on NHS sites, schools, and military installations), Onshore Energy, Offshore Energy (covering floating offshore wind), and the subsidiary Great British Energy – Nuclear (GBE-N), which delivers the UK's first SMR fleet at Wylfa via a ~£20bn contract with Rolls-Royce SMR. Key programmes include the £1bn Local Power Plan (targeting 1,000+ community projects by 2030), the £300m Supply Chain Fund for offshore wind and networks components, the £1bn Energy Engineered in the UK industrial programme, and a £1bn joint investment with The Crown Estate in offshore wind supply chains. Notable enterprise partners include Rolls-Royce SMR, ITM Power (10.4% equity stake), Copenhagen Infrastructure Partners, the National Wealth Fund, Scottish National Investment Bank, and Development Bank of Wales, alongside implementation partners Arup, Mace, Jacobs, WSP/Mott MacDonald, and the Amentum/Cavendish Nuclear JV (Litmus Nuclear).

GBE's strategic plan (published December 2025) targets 15 GW of clean energy generation and storage, £15bn of mobilised private finance, 10,000+ directly supported jobs, and 1,000+ community projects by 2030. The company takes minority equity stakes alongside other public finance institutions, reinvests returns from publicly owned assets back into UK capacity, and operates commercially independently while remaining accountable to government through its shareholder framework (DESNZ). Revenue model: capital allocation from HM Treasury plus debt/equity co-investment with the National Wealth Fund, deployed as equity investments, capital grants, and loans rather than priced commercial offerings.

Product overview

Great British Energy is a publicly owned energy investment and development company established by the UK Government in 2024/2025. Rather than a unified software product, it operates as a portfolio of investment programs and business divisions. The company encompasses GBE Local (community and public sector solar/renewables), Onshore Energy, Offshore Energy (including floating wind), and its nuclear subsidiary GBE-N for SMR development. Key programs include the Local Power Plan (£1 billion for 1,000+ community projects), the Supply Chain Fund (£300 million for offshore wind manufacturing), and the broader Energy Engineered in the UK programme (£1 billion total). The company functions as a developer, investor, and equity partner rather than a technology product vendor.
