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.
A second year of dramatic price falls means batteries are now cheap enough to make dispatchable solar economically feasible. With the cost of storing electricity at $65/MWh, storing 50% of a day's solar generation for use during the night-time hours adds $33/MWh to the total cost of solar. The global average price of solar in 2024 was $43/MWh.
Developer premiums and development expenses - depending on the project's attractiveness, these can range from £50k/MW to £100k/MW. Financing and transaction costs - at current interest rates, these can be around 20% of total project costs. 68% of battery project costs range between £400k/MW and £700k/MW.
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).
