If you''ve been tracking the energy storage market lately, you''ve probably noticed something wild: the reference price of energy storage systems (ESS) is plunging like a daredevil skydiver.
In 2025, the average energy storage cost ranges from $200 to $400 per kWh, with total system prices varying by technology, region, and installation factors.
The 2022 Cost and Performance Assessment provides the levelized cost of storage (LCOS). The two metrics determine the average price that a unit of energy output would need to be sold at
The annual Energy Storage Pricing Survey (ESPS) is designed to provide a reference system price to market participants, government officials, and financial industry participants for a
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
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
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

Home and business buyers typically pay a wide range for Battery Energy Storage Systems (BESS), driven by capacity, inverter options, installation complexity, and local
Energy storage systems (ESS) for four-hour durations exceed $300/kWh, marking the first price hike since 2017, largely driven by escalating raw material costs and supply chain disruptions. Geopolitical issues have
The 2022 Cost and Performance Assessment provides the levelized cost of storage (LCOS). The two metrics determine the average price that a unit of energy output would need to be sold at to cover all project costs inclusive
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
Energy storage systems (ESS) for four-hour durations exceed $300/kWh, marking the first price hike since 2017, largely driven by escalating raw material costs and supply chain disruptions.

The price is the expected installed capital cost of an energy storage system. Because the capital cost of these systems will vary depending on the power (kW) and energy (kWh) rating of the system, a range of system prices is provided. 2. Evolving System Prices
As we look ahead to 2024, energy storage system (ESS) costs are expected to undergo significant changes. Currently, the average cost remains above $300/kWh for four-hour duration systems, primarily due to rising raw material prices since 2017.
3. Purpose The annual Energy Storage Pricing Survey (ESPS) is designed to provide a reference system price to market participants, government officials, and financial industry participants for a variety of energy storage technologies at different power and energy ratings.
The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.
The survey methodology breaks down the cost of an energy storage system into the following categories: storage module, balance of system, power conversion system, energy management system, and the engineering, procurement, and construction costs.
“What we found is that with the 60% tariff, the cost [of a turnkey energy storage system] increases by 60% compared to 2025, so this is quite a big cost jump if the US actually decided to do so,” Kikuma says.
