BNEF finds 40% year-on-year drop in BESS costs
Around the beginning of this year, BloombergNEF (BNEF) released its annual Battery Storage System Cost Survey, which found that global average turnkey energy storage system prices
Factoring in these costs from the beginning ensures there are no unexpected expenses when the battery reaches the end of its useful life. To better understand BESS costs, it's useful to look at the cost per kilowatt-hour (kWh) stored. As of recent data, the average cost of a BESS is approximately $400-$600 per kWh. Here's a simple breakdown:
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.
BESS stands for Battery Energy Storage Systems, which store energy generated from renewable sources like solar or wind. The stored energy can then be used when demand is high, ensuring a stable and reliable energy supply.
Across global markets outside China and the United States, the total capex to build a long-duration (4 hours or more) utility-scale BESS project is around $125/kWh, of which around $75/kWh is for the core equipment shipped from China and around $50/kWh to install and connect the battery. A levelised cost of storage (LCOS) of $65/MWh.
Around the beginning of this year, BloombergNEF (BNEF) released its annual Battery Storage System Cost Survey, which found that global average turnkey energy storage system prices
As of most recent estimates, the cost of a BESS by MW is between $200,000 and $450,000, varying by location, system size, and market conditions.
