Buyers typically pay a broad range for utility-scale battery storage, driven by system size, chemistry, and project complexity. The price per kWh installed reflects balance of
Wider deployment and the commercialisation of new battery storage technologies has led to rapid cost reductions, notably for lithium-ion batteries, but also for high-temperature sodium-sulphur
This data is collected from EIA survey respondents and does not attempt to provide rigorous economic or scenario analysis of the reasons for, or impacts of, the growth in large-scale battery storage.
But what will the real cost of commercial energy storage systems (ESS) be in 2025? Let''s analyze the numbers, the factors influencing them, and why now is the best time

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.
While prices have fallen 80% since 2013, the average large-scale battery storage cost remains at $280/kWh (BloombergNEF 2023), creating financial hurdles for grid operators and developers.
According to the draft 2024/25 GenCost report – released on Monday – the price of battery storage has plunged more than 20 per cent in the last 12 months – echoing recent
Battery cost and performance projections in the 2024 ATB are based on a literature review of 16 sources published in 2022 and 2023, as described by Cole and Karmakar (Cole and
On average, installation costs can account for 10-20% of the total expense. Unlike traditional generators, BESS generally requires less maintenance, but it''s not maintenance

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.
Around the beginning of this year, BloombergNEF (BNEF) released its annual Battery Storage System Cost Survey, which found that global average turnkey energy storage system prices had fallen 40% from 2023 numbers to US$165/kWh in 2024.
This study shows that battery electricity storage systems offer enormous deployment and cost-reduction potential. By 2030, total installed costs could fall between 50% and 60% (and battery cell costs by even more), driven by optimisation of manufacturing facilities, combined with better combinations and reduced use of materials.
Let's analyze the numbers, the factors influencing them, and why now is the best time to invest in energy storage. $280 - $580 per kWh (installed cost), though of course this will vary from region to region depending on economic levels. For large containerized systems (e.g., 100 kWh or more), the cost can drop to $180 - $300 per kWh.
Informing the viable application of electricity storage technologies, including batteries and pumped hydro storage, with the latest data and analysis on costs and performance. Energy storage technologies, store energy either as electricity or heat/cold, so it can be used at a later time.
According to TrinaSolar that cost will total just $400 million. The company clarified to Renew Economy that this $400 million reflects only the first 330MW/1.32GWh stage of the project – but it still appears to set a new low for battery storage project costs in Australia.
