Wind power is not the answer
Demand varies from 2,000mw on summer nights to 5,000mw on winter peak demand evenings. These generators are paid capacity payments to compensate them for keeping the extra capacity available in winter which is not used at other times of the year.
The difference between 6,200mw capacity and 5,000mw peak demand is 1,200mw and this provides a reserve in case of a breakdown or unexpected demand above winter peak. As demand approaches full capacity the risk of black outs increases.
