The average price of electricity traded on day-ahead markets last year was around £83 per MWh but could have been as high as £121 per MWh, were it not for British windfarms limiting the role of gas power plants in setting prices, according to new analysis by the Energy and Climate Intelligence Unit (ECIU).

The saving of around £38 per MWh amounts to a price cut of 31 percent, and without it, another way, prices could have been about 46 per cent higher.

Britain currently has over 29GW of operational wind capacity, and almost 10GW under construction.
