I was interested by your article on British Energy's concern about intermittent supply from wind farms (NCE last week). There is a large pumped storage station at Dinorwig in Wales with about 288MW generating capacity. It was built to store energy from base load nuclear stations running overnight to be released to cope with morning and evening peaks.
Do we need another Dinorwig for wind farms?
Is it being used to stabilise wind energy production?
Will it have a larger role as nuclear stations are retired and wind capacity increases? If we need more energy storage who will pay for this facility that does not actually generate power?
