How cheap is battery storage? | Ember
This report provides the latest, real-world evidence on the cost of large, long-duration utility-scale Battery Energy Storage System (BESS) projects. Drawing on recent auction results from
Ember provides the latest capex and Levelised Cost of Storage (LCOS) for large, long-duration utility-scale Battery Energy Storage Systems (BESS) across global markets outside China and the US, based on recent auction results and expert interviews. 1. All-in BESS projects now cost just $125/kWh as of October 2025 2.
For large containerized systems (e.g., 100 kWh or more), the cost can drop to $180 - $300 per kWh. A standard 100 kWh system can cost between $25,000 and $50,000, depending on the components and complexity. What are the costs of commercial battery storage?
In 2025, the typical cost of a commercial lithium battery energy storage system, which includes the battery, battery management system (BMS), inverter (PCS), and installation, is in the following range: $280 - $580 per kWh (installed cost), though of course this will vary from region to region depending on economic levels.
The projections are developed from an analysis of recent publications that include utility-scale storage costs. The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time.
