The capacity value of energy storage is dependent on the volume of renewable capacity in the system. The following tables summarize the projected wind and solar capacity and energy in the CAISO system in 2022. These amounts were derived from resource portfolios being developed in the CPUC’s IRP process as of November 2019.
1. INTRODUCTION The Residual Load Curve modeling features of TIMES are intended for modelers who wish to improve the representation of non-dispatchable electricity generation in their energy system models, in particular, under a large scale penetration of intermittent renewable power supply.
Storage ELCC curves are derived by holding a resource portfolio constant and varying the capacity of storage.

The height of the curve indicates the capacity needed, while the area under the curve is the total amount of generation eeded to meet the baseload demand. For the base period, the marginal load is the area under the curve,
Namely: There is a strong positive relationship between the penetration of solar resources and the capacity value of energy storage. At low penetrations of solar, capacity contributions from storage are relatively low (2,000 – 4,000 MW) but at high penetrations, the capacity value grows substantially (6,000 – 8,000 MW).
