28/W, while battery energy storage system (BESS) prices see significant quarterly declines across project types. A new analysis from energy think tank Ember shows that utility-scale battery storage costs have fallen to $65 per megawatt-hour (MWh) as of October 2025 in markets outside China and the US. At that level, pairing solar with batteries to deliver power when it’s needed is now economically viable.
