In 2025, the typical cost of commercial lithium battery energy storage systems, including the battery, battery management system (BMS), inverter (PCS), and installation, ranges from $280 to $580 per kWh. Larger systems (100 kWh or more) can cost between $180 to $300 per kWh. The projections are developed from an analysis of recent publications that include utility-scale storage costs. Department of Energy's (DOE) Energy Storage Grand Challenge is a comprehensive program that seeks to accelerate. . According to BloombergNEF's Energy Storage Outlook 2025, global ESS costs average $150–$250 per kWh, depending on system scale and technology type. This is because of new lithium battery chemistries.
