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. Capacity factor compares output with the farm's full capacity, so it reads low while a farm is still being built, and when the grid operator has a farm cut its output because the network can't carry it (curtailment). 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).
