In 2025, the global average price of a turnkey battery energy storage system (BESS) is US$117/kWh, according to the Energy Storage Systems Cost Survey 2025 from BloombergNEF (BNEF), published last week (10 December). That was a 31% decline from 2024 numbers. Experts also anticipate further price declines next year, although at a slower rate than in 2025 due to high raw material costs and tariffs. BloombergNEF expects the. . Energy storage system prices have fallen to their lowest level on record, dropping to a global average of $117/kWh in 2025. At that level, pairing solar with batteries to deliver power when it's needed is now economically viable. . Technology advances that have allowed electric vehicle battery makers to increase energy density, combined with a drop in green metal prices, will push battery prices lower than previously expected, according to Goldman Sachs Research.

How much does battery storage cost in 2024?
BNEF's Levelized Cost of Electricity report indicates that the global benchmark cost for battery storage projects fell by a third in 2024 to $104 per megawatt-hour (MWh), as a glut in supply due to slower electric vehicle sales led to cheaper prices for battery packs.
Will battery storage prices fall again in 2025?
Battery storage costs have fallen dramatically over the past two years, and the decline continues. Following a steep decline in 2024, Ember's analysis indicates that prices continued to fall sharply again in 2025.
Why are storage costs falling?
Cheaper hardware isn't the only reason storage costs are falling. Longer battery lifetimes, higher efficiencies, and lower financing costs, helped by clearer revenue models such as auctions, have all contributed to the sharp drop in LCOS.
Is battery storage on track for another major fall in 2025?
As Ember global electricity analyst Kostantsa Rangelova put it, after a 40% drop in battery equipment costs in 2024, the industry is now on track for another major fall in 2025. The economics of battery storage, she said, are “unrecognizable,” and the industry is still adjusting to this new reality.
