The UK government will reintroduce subsidies for onshore wind and solar PV projects, doubling the amount of renewable energy it plans to subsidise in 2021.

Energy companies will compete for contracts in the government’s contracts for difference (CfD) scheme in an auction at the end of 2021, which could support up to 12 GW of renewable energy projects.

The announcement follows UK Prime Minister Boris Johnson’s pledge to upgrade facilities manufacturing the next generation of wind turbines, and his ten-point climate plan to achieve a “green industrial revolution.”

The government expects the next CfD auction to be almost double the size of the last 5.8 GW auction held September 2019, in which offshore wind costs fell by a third.
