Re: Nice though they are....
"We (in the uk) only have approx 27GWh of pumped storage added all together - which sounds ok, til you realise our base load could use that in an hour, and peak in 40 mins."
They can keep the lights on long enough to bring up something else from spinning reserve and THAT'S what counts - and power would be found to pump back in "off" hours, as they're a critical resource for peak matching given the UK's dire lack of large hydro.
