Surely a lot of the end of life plants are coal (or old nuclear) which

forecasts are that good.

Wind forecasts one pays for are rather better than the general ones,
but still not perfect.

In peruods of intermedaite wind, you can actually see teh onlie records
of predicted windpower versus actual.

They are out by up to 50% of the windpower.

Even when they are not, the slew rate and the rapidity of going from a
pretty near gale to calm in 5-6 hours is notable.


However, they do identify possible low wind
conditions days ahead. The prolonged absence of suitable wind for
days is a myth hyped by the anti-wind lobby, but the shorter periods
of reduced output can be forecast days ahead with reasonable
accuracy.


But Not good enouhg to avoid having a lot of standby and some hot
standby and some spinning reserve always in play.

Dave, give up. Wind power doesn't work. It mneets none of its design
objectives

Its not green. Its a scam.

Old coal plants can be used as part of an integrated system. They
could not be used were they the only plant, but that is not
something I suggested.

Weaseling away again.
