Eh? You don't do that. All you need is enough backup to cover the time
when you aren't generating enough. If you generate more than you can
use or store, you simply stop generating it and let the wind blow free.

Anyone competent, yes. I can't speak for HMG. Especially since they
don't include the cost of long-term storage of the radioactive debris
in the economics of nuclear power. Or the cost of global warming in
the cost of oil- and gas-fired stations.
