I did more exact although still crude approximation using following formula: (47GW+(13.1GW−8.4GW)×.7)×.285×24h×366 = 125 900 GWh This formula considers that 8.4 GW was installed on Q4, therefore they are assumed to contribute less than 50 %. This means that capacity factor was near 0.285 what is quite good. Typically onshore capacity factor is near 0.25 whereas on offshore it might be above 0.4. —Jouni
