Question to the HM Treasury:

To ask the Chancellor of the Exchequer, whether contingency planning is in place for potential macroeconomic disruption resulting from prolonged national electricity blackouts.

HM Treasury has a comprehensive framework for assessing and managing potential risks to the economic outlook, including those posed by national power outages. This framework involves systematic monitoring through internal risk monitors, risk governance forums, and collaboration with other government departments such as the Cabinet Office and the Department for Energy Security and Net Zero.

HM Treasury also engages with the Bank of England and Financial Conduct Authority (FCA), as the financial sector regulators, to ensure the sector is prepared to respond to a range of risks, including national power outages.
