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.
Generally speaking, the cost of the gas storage tank is the most expensive part of the entire system. Operation and maintenance costs include energy consumption and equipment maintenance. The current cost of compressed air energy storage systems is between US$500-1,000/kWh.
Additional storage technologies will be added as representative cost and performance metrics are verified. The interactive figure below presents results on the total installed ESS cost ranges by technology, year, power capacity (MW), and duration (hr).
The 2024 grid energy storage technology cost and performance assessment has noted improvements in energy density, which allows for greater storage capacity in smaller sizes, and in the lifecycle of these batteries, extending their usability and reducing replacement costs. Emerging Technologies
