You are correct to a certain extent, but since even thermal plants can have outages, there is a mechanism for covering yourself (Buy from Market/Hedge/CFD) that is not the problem.
As far as a company goes, if I am selling Alt. energy and making a killing, why would I need thermal, that debate goes on at the grid balancing level, way above a single company.
I realize that grid balancing already goes on but as Alt energy gets built out to a higher percentage of the mix there will be more balancing to do then can be handled by the present system. It's one thing to have to come up with say five percent of demand, quite another to come up with thirty or fifty percent of the total.
Hopefully the problem will be addressed as they go along and we will never see outages but it is not automatic. Just a couple of years ago wind turbines in Vermont sat idle on windy days because the power company didn't want or need the power.
