Energy Storage Value and Adoption Analysis

Evaluation of Key Value Drivers
Avoided Generation Capacity
We find storage can effectively offset the need for additional peaking
capacity in both 2020 and 2030, across all levels of deployment evaluated.
If discharging during system peak load hours (net
of renewable generation), storage offsets the need
for other capacity
Net peak load reductions valued at the market
price for capacity assumed in 2018 NV Energy IRP
We find 4-hour storage can effectively offset the
need for new generation capacity
Net load peaks concentrated in July and August
Net load peaks are relatively short duration, due to
high PV generation in summer months
