Abstract
Clean energy offers many benefits to consumers, including reducing consumers’ electricity bills, lowering total electricity system costs, and providing health and resilience benefits. States can accelerate consumers' access to these benefits with policies that support energy efficiency, demand flexibility, renewable energy and storage. Berkeley Lab developed a series of briefs that explore the consumer benefits of clean energy, and identify actions states can take to promote them.
Clean energy resources that are located behind the meter have the potential to benefit the hosting customers by providing affordability, environmental, and reliability and resilience value. Solar plus storage systems (PVESS) are clean energy resources that can supply backup power without requiring fuel resupply or increasing local emissions. This report examines the regional value of PVESS for resilience by calculating a benefit-cost ratio (BCR) that considers the annual resiliency benefits of PVESS and the annualized cost of the investment. In addition, we estimate the expected technical mitigation potential of PVESS systems at the county-level to these expected events, and characterize the customer interruption costs by determining the value of lost load at the state level.
