EPRI recently conducted a Phase 1 study to analyze the levelized cost of electricity (LCOE), capital costs, and performance of several energy storage technologies paired with a solar photovoltaic (PV) plant. The study evaluated a large parameter space of energy storage technologies and discharge durations, solar-to-storage ratios, and storage charging capacities to identify solar PV + storage configurations with the lowest LCOE and highest annual and seasonal capacity factors.
