@pauleastwood very cool.

Are those years at the top? I am not sure I understand your chart though. Is it saying that in '26/'27 offshore is expected to be £37.35 £/MWh? I would like to see more information.

I am in California where they just opened the north coast for Offshore wind. Our sea floor is... not as fun.

This is the UK’s fourth biannual “contracts for difference” (CfD) auction round (AR4). As well as seeing record-low prices, with 11GW of capacity secured, it is also by far the largest.
