UK announces Great British Grid, a public investor in electricity networks

The UK Department for Energy Security and Net Zero announced Great British Grid on September 29, 2026, a publicly owned body within Great British Energy to invest public capital alongside private investment in electricity network infrastructure, with reforms to expand self-build connections and faster competitive tendering of transmission projects. The release gives no investment figure, start date or legislation: start-up costs come from Great British Energy's existing budgets and the long-term budget is left to a future spending review.
