Energy Storage Value and Adoption Analysis

Evaluation of Key Value Drivers Customer Outage Reduction Value Findings The marginal benefit from avoided distribution outages declines as storage is added to the least-reliable feeders. Marginal Reliability Benefit ($/kW-yr) $100 $90 Incremental Reliability Benefit of Storage ($/kW-year) Simulated Reliability Benefit (noisy because least reliable feeders that are allocated storage may or may not actually experience outages) $80 $70 $60 $50 Fitted Trendline $40 $30 $20 1 $10 $0 0 200 400 600 800 1,000 1,200 1,400 Storage Installed (MW) Note: All values in nominal dollars. brattle.com 20
