According to Wikipedia we have 15 GWh of pumped storage capacity in Scotland. Per annum we use 27,000 GWh. So by my calculations we have a pumped storage battery that lasts about 5 hours.
(NB: I didn't check whether the power output of this battery is enough to actually meet demand, but wikipedia says it can run at full capacity for 22 hours, so no)
- mattmanser 9y agoIt can be reused more than once a year. You could use it every day, charge at night when there's no demand, discharge it during the peak. Really depends on how fast it can charge and discharge.
- bluGill 9y agoDepends more on how variable your supply is. If you have to meet a two week window with below average wind it isn't enough. If you have to just meet day to day variation in wind it is probably enough. Unfortunately two weeks without much wind are common in general weather patterns. Thus my gut reaction is it isn't enough. However we are now talking weather where local patterns are the important thing which means each situation needs to be considered separately.
- pjc50 9y agoSounds about right. It's used for demand-smoothing over fairly short periods. (I've been to Cruachan, well worth the visit even though you can't walk around the turbine hall any more)
