Electricity: Prices

Asked by Dr Ellie ChownsGreen PartyDepartment for Energy Security and Net ZeroTabled Answered 7 March 2025UIN 34129

The question

To ask the Secretary of State for Energy Security and Net Zero, for what reason the Government uses the marginal cost pricing system for electricity.

Answered by Michael Shanks

The wholesale electricity market, like most commodity markets worldwide, is based on marginal pricing. This reflects the value of consuming or generating an additional unit of electricity at any given time and ensures that generators increase or decrease their output to meet demand.
