6 FAQs about [New energy storage power generation ratio]

What is the optimal electricity storage power and energy capacity?

The optimal electricity storage power and energy capacity as well as the E/P ratio are relatively low in the 60% case. Note that electricity storage does not completely take up the renewable surplus in a least-cost solution; a sizeable fraction is also curtailed, as investments in both storage energy and power incur costs.

Why do we need 1 MW of gas storage capacity?

The reason: To shut down 1 MW of gas capacity, storage must not only provide 1 MW of power output, but also be capable of sustaining production for as many hours in a row as the gas capacity operates. That means you need many hours of energy storage capacity (megawatt-hours) as well.

What is energy-to-power (E/P) ratio?

The energy-to-power (E/P) ratio describes the ratio of the available energy of the ESS to the maximum charging power 10. The higher the E/P ratio, the more complicated or richer the duty cycle.
