Stormy Weather Brings Negative Energy Prices to Britain

On 2025-10-03T18:31:30+00:00, Britain is bracing for the arrival of Storm Amy, which is expected to bring winds of up to 95mph this weekend. The stormy weather has had an unexpected impact on the country's energy market, with prices falling below zero for the first time since 2023.

According to the latest data, day-ahead power prices for Saturday have settled at -42p/kWh on the Epex Spot SE exchange. This means that some households on agile tariffs, where prices drop if supply is high or demand low, could actually be paid to use electricity at certain points this weekend.

The surge in wind power generation is the primary driver behind the negative prices. Analysis by Bloomberg found that wind generation could reach as high as 24 gigawatts this afternoon, beating the previous record of 22.52 gigawatts set last December. As renewable energy outstrips demand on the national grid, energy prices have turned negative.

While most households will not directly benefit from the negative prices, as their energy has already been bought via fixed deals or standard variable tariffs, savvy customers on green tariffs that track the half-hourly price of wholesale markets could enjoy a weekend of much cheaper electricity.
