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.
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.
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.
Battery storage costs have evolved rapidly over the past several years, necessitating an update to storage cost projections used in long-term planning models and other activities. This work documents the development of these projections, which are based on recent publications of storage costs.
Home and business buyers typically pay a wide range for Battery Energy Storage Systems (BESS), driven by capacity, inverter options, installation complexity, and local permitting.
