In December its 175 turbines generated 369,000 MWh of electricity, beating the previous record of 317,000 MWh which was set the month before, also by London Array.
According to operator E.ON, the capacity factor for December was 78.9 per cent and the average wind speed for the month was 27mph.
Jonathan Duffy, general manager of London Array – which is owned by E.ON, Abu Dhabi-based renewables company Masdar and Canadian investment fund firm La Caisse de dépôt et placement du Québec – said: “Both the monthly and annual figures are excellent results for London Array and show the contribution we are making to the country’s energy supply as well as the UK’s renewable energy targets.
“Above average winds this winter have helped push production. We have pushed very hard over the past year to build on our earlier successes and develop our approach to turbine maintenance and repair.”
