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. The killer however is the maximum power output from them all running full chat is around 2.4GW - so enough to cope with the short term loss of a one major generator, or to balance out some demand during the day, but not enough to keep the lights on longer term even if you have vast generating reserves to allow more storage.

(currently cheap night time electricity is used to pump the water back uphill, but you can imagine if we also move significant amounts of space heating and transport over to electric power, that is not going to be available either!)
