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.
Will battery storage be profitable for curtailment only?
Battery storage is not likely to be profitable for curtailment only. As variable renewable energy (VRE) sources like wind and solar increase their penetration in electricity markets, their production has to be curtailed more often due to overproduction, system inflexibility or grid congestion.
Can generator flexibility reduce curtailment and energy storage?
We also find that generator flexibility can reduce curtailment and the amount of energy storage that is needed for renewable integration. Existing studies on the economic feasibility of energy storage are system-specific without considering the decarbonisation of electricity production or impacts of GHG taxes.
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.
Which energy storage technologies can avert renewable curtailment?
The figures show that with relatively low emissions taxes (i.e., $50 per ton or less), PHS and CAES are the only economically viable technologies for averting renewable curtailment. However, with higher emissions taxes, all of the energy storage technologies (except for Li-ion batteries) become cost-effective for this application.
Why is energy storage more cost-effective?
Moreover, increasing the renewable penetration or CO 2 tax makes energy storage more cost-effective. This is because higher renewable penetrations increase the opportunities to use stored renewable energy to displace costly generation from non-renewable resources.
