The Department publishes its levelised costs of electricity for a generic plant in the Generation Costs Report, most recently in 2023 (<a href="https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.gov.uk%2Fgovernment%2Fcollections%2Fenergy-generation-cost-projections&data=05%7C02%7CParliamentary.PQ%40energysecurity.gov.uk%7C32c44d834d5d4fdd1d3608dc6871b075%7Ccbac700502c143ebb497e6492d1b2dd8%7C0%7C0%7C638500084713423353%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=ATk5vvu5JFzV%2B1o2avZRW617Y6xeT0m5TCO6bkKafrk%3D&reserved=0" target="_blank">https://www.gov.uk/government/collections/energy-generation-cost-projections). These provide forecasts for 2025 to 2040. Gas CCGT is 114 £/MWh for 2025 and offshore wind is 44 £/MWh for 2025 (2021 price base). Levelised costs use a forecast of gas prices over the lifetime of a plant based on the latest published gas price forecasts at the time of publication (<a href="https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.gov.uk%2Fgovernment%2Fpublications%2Ffossil-fuel-price-assumptions-2019&data=05%7C02%7CParliamentary.PQ%40energysecurity.gov.uk%7C32c44d834d5d4fdd1d3608dc6871b075%7Ccbac700502c143ebb497e6492d1b2dd8%7C0%7C0%7C638500084713435471%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=v3lpX3rxy0bu1%2FJtL9JR0JIorLE48kgt9j5aJq4%2FcyQ%3D&reserved=0" target="_blank">https://www.gov.uk/government/publications/fossil-fuel-price-assumptions-2019).
