CCGT Generation

When we look at the problems of intermittent renewable energy, we usually focus on those long periods of wind drought. But just as problematic are the day to day and hour to hour swings in renewable generation and total demand.
The above chart plots CCGT generation over the last month, which has not been exceptional in any way as far as weather is concerned. Effectively, it is gas power which is balances out these swings. When wind power is low or demand is high, gas power obviously increases. And it can also be quickly turned down when the opposite occurs.
How will we manage these swings when we have no more gas power?
Over the month, CCGT generation has swung from just over 1 GW and as high as 18 GW.
