Maybe I should check my sources, but I thought UK peak usage was 50 to 60 GW. So you are talking about backing up the entire UK power generation capacity?
Yeah, it will eventually come to that, but not soon. As costs drop, this will become more feasible.

Does not make any sense. I think it is done with hydroelectric where
water is pumped back up at night when usage is down but what do you
do, pump back wind?
See:

\"Up to days at a time\".
Yep, this 1,500 MW scheme will make up for the UK shortfall when the
wind doesn\'t blow. The difference for the UK wind between blowing and
not blowing is close to 15,000 MW so to just backup the existing
windmills we need 10 of these pumped storage facilities. When even more
windmills are built the shortfall when the wind is absent requires
perhaps 20 to 30 of these facilities. And what happens for when the wind
doesn\'t blow for 14 days and the pumped water head runs dry after a
couple of days?
This scheme probably only makes financial sense if we rely on windmills
where they can sell back the electricity at 10x the going rate when
there is no wind.
