Gas power plants and batteries have different timescales. Grids with a lot of renewable energy need a slice of capacity that can ramp up faster than a gas turbine. "The fastest loading gas turbine models produce 30% load delivery after 7 minutes" -- http://www.wartsila.com/energy/learning-center/technical-comparisons/combustion-engine-vs-gas-turbine-ramp-rate http://www.wartsila.com/energy/learning-center/technical-com... If you've driven a Tesla, you may have noticed that they can reach peak a bit faster than that.
