Energy storage devices and solar power curtailment

4 FAQs about [Energy storage devices and solar power curtailment]

Can energy storage reduce curtailment?

A key element of using energy storage to integrate renewable energy and reduce curtailment is identifying the timescales of storage needed—that is, the duration of energy storage capacity per unit of power capacity.

Can energy storage devices avoid curtailment?

The ability to avoid curtailment is a function of both the power and energy capacities of the energy storage device. We perform simulations with varying energy storage sizes to examine curtailment reduction with a focus on the role of duration.

How does a curtailment affect a power system?

Curtailment in effect undermines a jurisdiction’s ability to harness what is increasingly the lowest cost source of power generation on the system. A relatively high level of curtailment can be expected for power systems with very high shares of variable renewables (solar PV and wind energy).

Is a high level of solar PV curtailment a good idea?

A relatively high level of curtailment can be expected for power systems with very high shares of variable renewables (solar PV and wind energy). In fact, having substantial oversupply of solar PV during certain days of the year or hours of the day may still make sense from a system perspective for several reasons:
