Course what the silly green moo forgets that on days like today the
freaking wind output is sod all so on windless days and they still think
that a few offshore wind farms will have sufficient wind blowing to
cover the shortfall.



According to the BBC text news, it will supply power for 2 million
homes. I don't think so, not even in a gale.

Certainly not in a gale - they will shut down.

But Ofgem reckons the average medium sized house uses 3,100kWh per
year http://tinyurl.com/h9kz4w7 , or an average rate of 0.353kW. The
average output from Hornsea 2 will be 0.7GW, allowing for a claimed
39% load factor on 1.8GW, so they can reasonably claim to be able to
supply 2 million homes at the 0.353kW rate (1.98 million homes to be
exact, if one can be exact about these things). On the same basis,
Hornsea 1 will supply a little over 1 million homes. But that's the
trouble with averages like that in this situation. They tell you
nothing about the doldrum days.

As an aside, and answering my own question about whether Dong Energy

http://www.peevish.co.uk/slang/d.htm

is actually Chinese, Dong apparently stands for Danish Oil and Natural
Gas, and is 76% owned by the Danish government. But coincidentally,
Dong in Chinese means East, which would also be appropriate if they
were Chinese-funded.
