Renewable energy record achieved at London Array

By VictoriaBlake

London Array has set a new
record for the amount of clean electricity produced by an offshore wind farm in
a single calendar month.

December 2015 saw its 175
turbines generate 369,000 MWh of electricity – considerably above target and
well above the previous best of 317,000 MWh set last November. The capacity factor
for the month, which saw average wind speeds of 11.9m/s (27mph), was 78.9 per

The two successive months of
production brought net overall output for the year to some 2,500,000 MWh,
enough to meet the needs of more than 600,000 UK households*.

Jonathan Duffy, General Manager of London Array, which
is the world’s largest operational offshore wind farm, 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
higher but that is only part of the story: we have a great team of people who
support the operation and maintenance of the wind farm.

“We have pushed very hard over the past year to
build on our earlier successes and develop our approach to turbine maintenance
and repair. Together with key contractors DONG Energy and Siemens we have
focused on operational efficiency and expanding the amount of time our
technicians are able to work offshore. This has helped ensure we extracted the
maximum power from the wind and kept turbine availability above 98 per cent over
the winter.

“Our performance is also good news for the
environment as it will have
prevented the release of some 1,075,000
tonnes of
carbon dioxide** in 2015, the main gas linked to climate change.”

London Array Limited is owned by a consortium of
three world-leading renewable energy companies: E.ON (30%), DONG Energy
(25%) and Masdar (20%) – and La Caisse de dépôt et placement du Québec (25%), a
global investor and one of the largest institutional fund managers in Canada
and North America. Their combined
experience and expertise help ensure the continuing success of the wind
