Battery storage is a known resource on the coasts, but what happens when you use batteries in the heartland of America – the Southwest Power Pool (SPP). This session explores findings from a 2-year-long pilot involving 28 residential battery systems and extrapolates their potential impact if scaled to 1,000 systems. We will analyze how these batteries performed during load management events, typical daily discharge and charge cycles, load reductions achieved, and how their aggregated response could improve system capacity during critical periods. The analysis includes the impact on the Public Service Company of OK (PSO) distribution and SPP market. Attendees will gain insight on how small-scale pilots can inform large-scale strategy to deploy a utility battery DERs program. This session will uncover what it really takes to move the SPP needle in Middle America.
