What a MWh of GB wind earns day-ahead, and how that falls below baseload as more is built. Plus what NESO pays wind farms to switch off.
| Year | Output | Baseload | Capture | Rate | Neg. hours | Sold in neg. hours | Delivered capture | Turned down | NESO paid wind | Wind paid NESO |

From 2022, capture is on the position sold day-ahead: metered output plus what NESO turned down. Turned down is its share of that; earlier years use metered output.
