The average cost for DC energy storage systems is not easily defined due to numerous influencing factors including the type and capacity of the system. Prices typically range from $5,000 to over $1,000,000, reflecting significant variation based on size and technology.
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 various technologies.
US-made battery energy storage system (BESS) DC container solutions will become cost-competitive with those from China in 2025 thanks to incentives under the Inflation Reduction Act (IRA), Clean Energy Associates said.
Understanding the full cost of a Battery Energy Storage System is crucial for making an informed decision. From the battery itself to the balance of system components, installation, and ongoing maintenance, every element plays a role in the overall expense.
Informing the viable application of electricity storage technologies, including batteries and pumped hydro storage, with the latest data and analysis on costs and performance.
Costs for DC SB and equipment comprising ESSs are tracked and available from multiple sources with this report focused on quantifying the additional costs of system integration, EPC, project development, grid integration, and operations required for
This paper proposes an optimization of the capacity and cost of a hybrid ESS, comprising a battery and a supercapacitor, in a standalone DC microgrid. This optimization is achieved by calculating the cut-off frequency of a low-pass filter (LPF).
As of April 2025, the average storage system cost in Washington D.C. is $1250/kWh. Given a storage system size of 13 kWh, an average storage installation in Washington D.C. ranges in cost from $13,812 to $18,688, with the average gross price for storage in Washington D.C. coming in at $16,250.

Battery Energy Storage Systems (BESS) are becoming essential in the shift towards renewable energy, providing solutions for grid stability, energy management, and power quality. However, understanding the costs associated with BESS is critical for anyone considering this technology, whether for a home, business, or utility scale.
Non-battery systems, on the other hand, range considerably more depending on duration. Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours.
Base year costs for utility-scale battery energy storage systems (BESS) are based on a bottom-up cost model using the data and methodology for utility-scale BESS in (Ramasamy et al., 2022). 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.
Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours. Li-ion LFP offers the lowest installed cost ($/kWh) for battery systems across many of the power capacity and energy duration combinations.
The cost categories used in the report extend across all energy storage technologies to allow ease of data comparison. Direct costs correspond to equipment capital and installation, while indirect costs include EPC fee and project development, which include permitting, preliminary engineering design, and the owner’s engineer and financing costs.
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.
