“Today I can announce our plan for Great British Grid. A new branch of Great British Energy. A publicly-owned company that will challenge the private sector operators. It will increase competition, drive down costs and speed up connections so businesses can expand and grow more quickly.”

Where it stands

The Department for Energy Security and Net Zero announced Great British Grid the same day: a new publicly owned body within Great British Energy that will invest public money, alongside private investment, in electricity network infrastructure. Its start-up costs come from Great British Energy's existing budgets; the long-term budget is to be considered at a future spending review. No date is given for setting it up. The card moves when Great British Grid is set up or given a budget of its own.
