Flat bat­ter­ies…

The Scotsman - - Perspective / Letters To The Editor -

The elec­tric bat­tery stor­age fa­cil­ity in West Loth­ian (The Scots­man, 12 Septem­ber) I’m afraid is an­other case of trum­pet­ing a solution with no re­gard to the na­ture and mag­ni­tude of the prob­lem it is sup­posed to solve.

If the de­vice de­scribed wrongly as be­ing one of 20MW is ac­tu­ally of 20 megawatt-hours ca­pac­ity then that is equiv­a­lent to just about 20 sec­onds of Scot­land’s av­er­age elec­tric­ity us­age. It may help to iron out tiny rip­ples in sup­ply/de­mand but is go­ing to con­trib­ute pre­cious lit­tle to bal­anc­ing out windy and non­windy days as claimed .
