What Does Green Energy Storage Cost in 2026?
You''re looking at an average cost of about $152 per kilowatt-hour (kWh) for lithium-ion battery packs, which represents a 7% increase since 2021.
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 U.S. battery storage capacity illustrates this trend, skyrocketing from 47 MW in 2010 to 17,380 MW in 2025. Large-scale battery storage is expected to soar from 1 GW in 2019 to 98 GW by 2030. The energy storage sector experienced over 600% growth in operational systems from 2015 to 2021.
As we look ahead to 2024, energy storage system (ESS) costs are expected to undergo significant changes. Currently, the average cost remains above $300/kWh for four-hour duration systems, primarily due to rising raw material prices since 2017.
