The CfD scheme & the wind auctions

Great Britain's main support mechanism for low-carbon generation. We trace why it exists, how the auction actually works, and what six Allocation Rounds reveal — including the collapse in offshore wind strike prices and the round that cleared zero offshore wind.

02 Why government built it

What the CfD is designed to solve

A CfD swaps volatile merchant revenue for a stable, contracted price. That single change cascades into lower financing costs, faster deployment, and a transparent price-discovery mechanism for government.

03 How the mechanism works

Strike price, reference price, and the two-way payment

A CfD is a private-law contract between a generator and the Low Carbon Contracts Company (LCCC). It tops up — or claws back — the difference between an agreed strike price and the market reference price.

The two-way difference paymenti

Drag the strike price and the market (reference) price to see the CfD top-up or payback.

Pot 1 — Established

Pot 2 — Less established

Pot 3 — Offshore wind

04 Round-by-round data

Six allocation rounds, one decade of price discovery

All strike prices are in 2012 real £/MWh, the basis DESNZ uses so rounds stay comparable. Use the filter to switch technology, and read each round against the last. The full figures are also in the table at the foot of this section.
