Nature seems to do quite well with a load factor of about 7% on photosynthesis so PV and wind are doing quite well.

EDIT - Should have checked before going to print. I exaggerate, it's only 3 to 6%. http://en.wikipedia.org/wiki/Photosynthetic_efficiency

That's the efficiency of energy conversion? Could be fun to calculate "load factor" based on hours of sunshine - something like 50%???

I finally got round to watching the last episode of the Secret Life of the National Grid yesterday.

Apparently, when Thatcher was on her privatisation spree, the sell-off of the national nuclear assets had to be cancelled because, when the books were examined (the first time the accounts had been looked at seriously), it was discovered that, far from being the cheap electricity producer we had been told it was, the decommisisoning costs of one nuclear power station alone would exceed all the likely government receipts from the sell-off of all grid-related assets. Consequently no one wanted to touch nuclear with that uncertainty about who would pick up the tab for all those revealed costs and no one has since built nuclear without goverment subsidy and the liabilities tacitly going to the local population - as the Japanese are now discovering.


Here we go round again!

Up till privatisation, who had owned the entire ESI?

What were the profits of the ESI since the time it was taken into public ownership? (And yes, year upon year the CEGB turned a profit - usually scaled back so as not to ruffle the feathers of the public. And the regional electricity companies (also public owned) also made profits).

And who was understood to have been sequestering part of the profits for nuclear decommissioning?

Was that money declared available to the putative buyers of the nuclear generators?

If not, where did that money go?

And which organisation was it that exacted a nuclear decommissioning levy of 9% on electrity bills in the 90s?

And where did that money go?

Was it declared available to the putative buyers of the nuclear generators?

And if you look at the submissions for the new round of nuclear stations from the likes of Horizon and EdF you'll find full provision for decommissioning in both the project price and the projected cost of electricity generation.

I feel a cartoon coming up anytime soon . . .

Assuming that plants are only working for the 50% of the day that is daylight the load factor would then be 1.5 to 3% wouldn't it?
