Energy storage system prices have fallen to their lowest level on record, dropping to a global average of $117/kWh in 2025. The new figures come from BloombergNEF''s Energy Storage...
Turnkey energy storage system prices fell sharply this year to a global average of $117/kWh, down 31% from 2024. This marks the lowest level in BloombergNEF''s annual cost survey, driven by continued
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
Global average prices for turnkey battery storage systems fell by almost a third year-over-year, with sharp cost declines expected to continue. In 2025, the global average price of a
In this work we describe the development of cost and performance projections for utility-scale lithium-ion battery systems, with a focus on 4-hour duration systems. The projections are developed from an
The goal of this report is to summarize energy storage capital costs that were obtained from industry pricing surveys.
The following resources provide information on a broad range of storage technologies.
