Output is the sum of the Balancing Mechanism units above. Confirmed figures are Elexon's metered output, about a week behind; the latest days are indicative: the output each unit notified National Grid it planned, less any cuts once they're on record. Cuts (curtailment) are the output the grid operator had the farm turn down, usually because the network couldn't carry it: the bids it accepted from the farm in the Balancing Mechanism, on record a few days later, with what they were paid. Capacity factor compares output with the farm's full capacity, so it reads low while a farm is still being built, and when its output is cut. Unit-to-farm mapping follows Nost, Ole Anders (2025), Offshore wind power production in the North Sea; farms generating since then from the Elexon BM unit register, with capacities from the Renewable Energy Planning Database (Q2 2026).
