Average auction price by project commissioning date, 2012-2022

Notes

Other competitively set remuneration schemes include green certificate systems and competitive contract price-setting as part of the renewable portfolio standards or corporate PPAs. Auction prices are not levelised to take price escalations or other benefits such as tax incentives or split tariffs into account. Prices are nominal; higher values for onshore wind in 2017‑18 result from the United Kingdom’s contracts for difference (CfD) auction, and in 2021 are associated with a delayed project from the Jordanian auction held in 2014.
