Historical and prospective lithium-ion battery cost trajectories
Thus, a collection of prospective developments in manufacturing chain and battery cell design, material price estimations, and planned expansions in the production capacities
Average Installed Cost per kWh in 2025 In today's market, the installed cost of a commercial lithium battery energy storage system — including the battery pack, Battery Management System (BMS), Power Conversion System (PCS), and installation — typically ranges from: $280 to $580 per kWh for small to medium-sized commercial projects.
Energy storage system costs for four-hour duration systems exceed $300/kWh for the first time since 2017. Rising raw material prices, particularly for lithium and nickel, contribute to increased energy storage costs. Fixed operation and maintenance costs for battery systems are estimated at 2.5% of capital costs.
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.
Energy storage deployments grew by 50% year-over-year, driving demand and impacting battery costs The demand for energy storage is rising rapidly, with deployments increasing by 50% year-over-year. This growth is being driven by the need for grid stability, renewable energy storage, and backup power solutions.
