Comment:
Most critical will be how much increase in ancillary services would be needed for every GW of wind power. Clearly present >7GW hydro is much greater than the 250MW range being used now.

The other consideration is the time it takes CCGT and coal-fired power to start up from standby, either a cold start or a hot start and how much power is being used to keep at "cold start" and "hot start" status.
