Resilient Southeast is a series of reports exploring the obstacles and opportunities for solar PV and battery storage to strengthen the resilience of communities throughout the Southeast. The series evaluates the current policy landscape and economic potential for solar and battery storage to provide clean, reliable backup power to critical facilities in five cities: Atlanta, GA; Charleston, SC; Miami, FL; New Orleans, LA; and Wilmington, NC. When the economic value of resilience is accounted for, solar+storage was proven to be a positive investment for all locations and building types examined.
