Expected price reduction of energy storage system costs

According to BloombergNEF's annual survey, battery prices in 2025 remained at $108 per kilowatt-hour, an eight percent decrease. Experts also anticipate further price declines next year, although at a slower rate than in 2025 due to high raw material costs and tariffs. . 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 suite of. . Global average prices for turnkey battery storage systems fell by almost a third year-over-year, with sharp cost declines expected to continue. BloombergNEF expects the. . The technology is forecast to overcome tariffs and high metal costs to win new savings and help drive adoption of electric vehicles and energy storage systems.
