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
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.
Battery storage prices have gone down a lot since 2010. In 2025, they are about $200–$400 per kWh. This is because of new lithium battery chemistries. Different places have different energy storage costs. China's average is $101 per kWh. The US average is $236 per kWh. Knowing the price of energy storage systems helps people plan for steady power.
Different places have different energy storage costs. China's average is $101 per kWh. The US average is $236 per kWh. Knowing the price of energy storage systems helps people plan for steady power. It also helps them handle money risks. As prices drop and technology gets better, people need to know what causes these changes.
The projections are developed from an analysis of recent publications that include utility-scale storage costs. The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time.

According to BloombergNEF''s Levelized Cost of Electricity 2026 report, battery storage costs reached record lows in 2025 even as most other clean power technologies became more
According to BloombergNEF''s Levelized Cost of Electricity 2026 report, the cost of battery storage projects plummeted to new lows in 2025 even as most other clean power technologies
A new analysis from energy think tank Ember shows that utility-scale battery storage costs have fallen to $65 per megawatt-hour (MWh) as of October 2025 in markets outside China and
In 2025, the average energy storage cost ranges from $200 to $400 per kWh, with total system prices varying by technology, region, and installation factors.
As solar and wind adoption accelerates, the per kWh price of battery systems determines whether green energy can truly replace fossil fuels. In 2023, lithium-ion batteries averaged $150-$200 per kWh
Explore utility scale battery storage cost per kWh trends in China, recent price drops, and future outlooks for 2025.
Buyers typically pay a broad range for utility-scale battery storage, driven by system size, chemistry, and project complexity. The price per kWh installed reflects balance of hardware,
Global average prices for battery storage systems fell by almost a third year-over-year, with sharp cost declines expected to continue.
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
