REopt Evaluates Commercial Solar Plus Storage
NREL used the REopt™ model to evaluate the economics of solar paired with battery storage across the country, conducting thousands of optimization runs to evaluate economic viability across different building types, climate zones, and utility rate tariffs. NREL’s analysis considered multiple potential value streams including peak shaving, energy arbitrage, frequency regulation, capacity markets, and the value of resiliency. The results show where solar and storage may be cost-effective in the near-term and long-term.
The REopt analysis is being used to identify cost-optimal technology combinations of solar and storage for a variety of building types and market conditions; explore methods to value the contribution of solar-plus-storage to electric system resiliency; characterize market potential for multiple technology and policy trajectories; and support identification of policy and regulatory options to support solar-plus-storage deployment.
