Energy storage needs for the substitution of fossil fuel power plants with renewables
It is also of interest that, for minimum storage capacity, substantially more wind energy must be produced than solar energy when the coal power plants are substituted alone (31% of the total). However, when the natural gas power units – which currently produce the intermediate and peak power – are substituted, the contributions

Peaking power plant
OverviewPeak hoursRenewable energyTypesBase load power plantsSee also
Peaking power plants, also known as peaker plants, and occasionally just "peakers", are power plants that generally run only when there is a high demand, known as peak demand, for electricity. Because they supply power only occasionally, the power supplied commands a much higher price per kilowatt hour than base load power. Peak load power plants are dispatched in combination with base load power plants, which supply a dependable and consistent amount of electricity, to me
