Energy Storage Cost and Performance Database
DOE''s Energy Storage Grand Challenge supports detailed cost and performance analysis for a variety of energy storage technologies to accelerate their development and deployment.
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.
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.
r (kWh) of lithium-ion battery storage was around $1,200. Today, thanks to a huge push to develop cheaper and more powerful lithium-ion batteries for use in electric vehicles (EVs), that cost has dropped to between $150 and $200 per kWh, a d by 2025 it had been predicted to fall to under $100/kWhThe future
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.

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
The utility-scale battery storage cost per kWh has fallen by 82% since 2013, reaching an average of $150–$200/kWh globally in 2024. This seismic shift is reshaping energy markets, enabling
Clean Energy Clean Transport December 9, 2025 New York, December 9, 2025 – lithium-ion battery pack prices have dropped 8% since 2024 to a record low of $108 per kilowatt-hour,
Battery pack prices for stationary storage fell to $70/kWh in 2025, 45% lower than in 2024. This was the steepest decline of any segment, making stationary storage the lowest-priced category
