Moray East has achieved its full contracted output of 900MW to the UK national transmission grid.
The offshore wind farm has been able to produce electricity while construction was underway.
Moray East project director Enrique Alvarez said: “Offshore wind has a unique advantage; we don’t have to wait until work has finished to switch on.
“Output can start after the first few turbines have been commissioned and increase incrementally as work progresses.
“Over the period of nine months from June last year, as more and more of our 100 turbines were installed, we supplied more and more electricity to the gird – 1,415,000 megawatt hours.
“While construction was underway, between starting our first turbine and finishing the wind farm, we supplied enough electricity to meet the annual needs of every household in Edinburgh and Aberdeen – with enough left over for most of the County of Moray as well.
“This, of course, is our output from a fraction of a year with a fraction of our turbines.
“I am delighted to announce that Moray East has now achieved its full contracted output of 900MW.
He acknowledged and thanked everyone who has contributed to this achievement; from introducing the project as a concept more than a decade ago, to delivering it as “today’s reality in shining steel”.
