Gas Keeps Grip on UK Power Prices Even as Renewables Rise

Gas-fired power plants set UK electricity prices about two-thirds of the time last month, highlighting the fuel’s stubborn grip on the market even as renewable generation continues to climb.

The data shows a growing mismatch between how Britain produces its power and how prices are set. Gas accounted for only about a fifth of the electricity mix in March, yet it mostly remained the country’s “marginal” fuel, the last — and most expensive — fuel brought on to meet demand.
