Battery Energy Storage Impact and Benefits Assessments in MISO

Aurora Energy Research analysis shows that 10 GW of battery storage across the Midwest could save consumers $25 billion while supporting grid reliability for 45 million Americans, as the region needs a 500% increase in storage capacity by 2035 to handle demand growth that recently drove electricity prices up over 2,000%.

A new research study by Aurora Energy Research, commissioned by the American Clean Power Association, demonstrates that installing 10 GW of battery storage throughout the Midwest and Central U.S. regions would deliver $25 billion in consumer savings while enhancing electrical grid stability for 45 million Americans.

The study highlights the urgent need for expanded energy storage as the MISO grid—covering 15 states—experiences rapidly growing electricity demand that strains existing infrastructure. To meet reliability standards through 2035, battery capacity must increase five-fold from current levels. Battery systems provide crucial grid support by storing surplus energy and releasing it during peak demand periods. This capability proved essential during recent summer months when MISO electricity prices spiked over 2,000%, underscoring the critical role storage will play in controlling future energy costs and maintaining system reliability.
