Evaluating the Cost Benefits of U.S. Utility-Scale Photovoltaics Plus Energy Storage Systems
- National Renewable Energy Laboratory (NREL), Golden, CO (United States)
Utility-scale photovoltaics (PV) system market growth has been rapid for several years. Today, with the cost reductions of energy storage technologies, the application of combing PV and energy storage has become feasible and beneficial, especially for the areas that only have PV standalone systems and need to shift the peak load to meet the evening electricity demand. Overall, the utility-scale PV plus energy storage systems can provide dispatchable energy and reliable capacity. This study details cost factors, including labor costs, material costs, overhead, and permitting costs using a systemlevel bottom-up cost modeling approach. We use this model to benchmark PV plus storage installation system cost and identify cost difference for AC and DC coupled systems and duration variation. Finally, we assess the cost reduction opportunities of co-locating PV system with energy storage system in order to indicate the possible economic impacts of PV plus storage configuration and help future research and development (R&D) effects in the context of U.S. energy storage policymaking.
