How much does a commercial battery energy storage system cost?

Average Installed Cost per kWh in 2025 In today’s market, the installed cost of a commercial lithium battery energy storage system — including the battery pack, Battery Management System (BMS), Power Conversion System (PCS), and installation — typically ranges from: $280 to $580 per kWh for small to medium-sized commercial projects.

Are battery electricity storage systems a good investment?

This study shows that battery electricity storage systems offer enormous deployment and cost-reduction potential. By 2030, total installed costs could fall between 50% and 60% (and battery cell costs by even more), driven by optimisation of manufacturing facilities, combined with better combinations and reduced use of materials.

How much will a battery cost in 2022?

Global average battery prices declined from $153 per kilowatt-hour (kWh) in 2022 to $149 in 2023, and they’re projected by Goldman Sachs Research to fall to $111 by the close of this year.
