• CLM-0276 The price the UK government agrees to pay offshore wind farms, per unit of electricity actually generated, dropped sharply from 2015 to 2022, then rose again through 2024 and 2026. In 2023 no offshore wind developer was willing to build at the price on offer, so zero megawatts were awarded that year. These are real, dated contract prices from competitive auctions, not projections, but they are for electricity as generated, not for guaranteed firm delivery.
• CLM-0279 A few UK renewable-energy auction contracts are for technologies that can generate more steadily than wind or solar: waste-to-energy plants, biomass-with-heat plants, and a handful of small pilot geothermal plants in Cornwall. Their contracted prices, in fixed 2012-price terms, range from about 46 to 119 pounds per megawatt-hour. These are the best real UK price signals in the register for something closer to firm power, but they are all small in scale and none of them carries a formal obligation to deliver on demand.
