NREL Tool Finds Effective Behind-the-Meter Energy Storage Configurations

The Energy Department’s (DOE) National Renewable Energy Laboratory (NREL) has used the Battery Lifetime Analysis and Simulation Tool (BLAST) to confirm that energy storage for demand-charge management can deliver attractive economic benefits. The analysis paired recent utility rate structures with historic data on solar photovoltaic electricity generation and commercial facility loads to evaluate 6,860 unique scenarios. The results revealed that, in the absence of incentives, small battery systems reducing peak demand by 2.5 percent offer the most attractive return on investment.
