Combined cycle natural gas turbines are extremely easy to throttle compared to baseload like coal or nuclear. Even most diesel/bunker fuel facilities that were used for peaking have been shuttered or switched to natural gas, because of cost as well.
Natural gas turbines are just fine as a peaking stop gap until we have the renewables dispatchability problem solved.
