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 Energy Storage Systems represent the fastest-growing segment of the storage market, driven by rapidly declining costs and versatile applications. BESS technology has evolved dramatically over the past decade, with lithium-ion chemistries dominating utility-scale deployments.
Base year costs for utility-scale battery energy storage systems (BESSs) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2023). The bottom-up BESS model accounts for major components, including the LIB pack, the inverter, and the balance of system (BOS) needed for the installation.
Battery Storage Costs Have Reached Economic Viability Across All Market Segments: With lithium-ion battery pack prices falling to a record low of $115 per kWh in 2024—an 82% decline over the past decade—energy storage has crossed the threshold of economic competitiveness.

Dan Shreve of Clean Energy Associates looks at the pricing dynamics helping propel storage to ever greater heights. This is an extract of a feature article that originally appeared in
Comprehensive guide to renewable energy storage technologies, costs, benefits, and applications. Compare battery, mechanical, and thermal storage systems for 2025.
In support of this challenge, PNNL is applying its rich history of battery research and development to provide DOE and industry with a guide to current energy storage costs and performance metrics for
Three projections for 2022 to 2050 are developed for scenario modeling based on this literature. In all three scenarios of the scenarios described below, costs of battery storage are anticipated to continue
As of 2024, the average price for a utility-scale BESS is approximately $148/kWh 1. For a 1 GWh system, this translates to $148 million. It''s important to note that this cost includes not just the
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
Drawing on recent auction results from Saudi Arabia, India and Italy, along with in-depth interviews with project developers, suppliers and analysts across global markets, it captures the most
