lithium-ion battery systems, with a focus on 4-hour duration systems. The projections are developed from an analysis of 19 publications that consider utility-scale storage costs.
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.
This report is available at no cost from the National Renewable Energy Laboratory at Figure 5. Cost projections for power (left) and energy (right) components of lithium-ion systems. Note the different units in the two plots. These power and energy costs can be used to specify the capital costs for other durations.
Values range from 0.948 to 1.11. 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.
We only used projections for 4-hour lithium-ion storage systems. We define the 4-hour duration as the output duration of the battery, such that a 4-hour device would be able to discharge at rated power capacity for 4-hours.
The projections are developed from an analysis of 19 publications that consider utility-scale storage costs. The suite of publications demonstrates varied cost reductions for battery storage over time. Figure ES-1 shows the low, mid, and high cost projections developed in this work (on a normalized basis) relative to the published values.
These components are combined to give a total system cost, where the system cost (in $/kWh) is the power component divided by the duration plus the energy component. Figure 5. Cost projections for power (left) and energy (right) components of lithium-ion systems.
On October 10, 2025, China's first large-scale lithium-ion battery energy storage power station commenced operations in Guangxi Province. This project, which is located in the Nanning area, aims to enhance the stability and efficiency of the local power grid. (Representative image) iStock Photos China just fired up a next-gen battery hub blending lithium and sodium in its latest energy leap. This facility, spanning 50 mu (3. It can store 800,000 kWh of electricity per day, which can be used by 270,000 households.
A battery energy storage system (BESS), battery storage power station, battery energy grid storage (BEGS) or battery grid storage is a type of technology that uses a group of in the grid to store. Battery storage is the fastest responding on, and it is used to stabilise those grids, as battery storage can transition from standby to full power in u.

All-in BESS projects now cost just $125/kWh as of October 2025 2. With a $65/MWh LCOS, shifting half of daily solar generation overnight adds just $33/MWh to the cost of solarIn 2025, the typical cost of a commercial lithium battery energy storage system, which includes the battery, battery management system (BMS), inverter (PCS), and installation, is in the following range: $280 - $580 per kWh (installed cost), though of course this will vary from region to region. In 2025, average turnkey container prices range around USD 200 to USD 400 per kWh depending on capacity, components, and location of deployment. But this range hides much nuance—anything from battery chemistry to cooling systems to permits and integration. Battery storage: Lithium-ion vs. lead-acid significantly impacts cost and. As of 2024–2025, BESS costs vary significantly across different technologies, applications, and regions: Lithium-ion (NMC/LFP) utility-scale systems: $0. 35/kWh, depending on duration, cycle frequency, electricity prices, and financing costs.
