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.
The suite of publications demonstrates wide variation in projected cost reductions for battery storage over time. Figure ES-1 shows the suite of projected cost reductions (on a normalized basis) collected from the literature (shown in gray) as well as the low, mid, and high cost projections developed in this work (shown in black).
Battery cost projections for 4-hour lithium-ion systems, with values relative to 2024. The high, mid, and low cost projections developed in this work are shown as bold lines. Published projections are shown as gray lines. Figure values are included in the Appendix.
By expressing battery system costs in $/kWh, we are deviating from other power generation technologies such as combustion turbines or solar photovoltaic plants where capital costs are usually expressed as $/kW. We use the units of $/kWh because that is the most common way that battery system costs have been expressed in published material to date.
While amendments to the Renewable Energy Act introduced the Feed-in Premium to encourage renewable integration, no unified framework exists for battery storage. Project developers cite uncertainty around licensing, grid access, and fire safety rules—raising both compliance costs and risk premiums. Urban density further compounds the problem.
The overall market is expected to grow 11% annually, from USD 793.8 million in 2024 to USD 2.5 billion by 2035. Residential adoption is moving faster. Home lithium-ion battery systems generated USD 278.5 million in 2023 and could surge to USD 2.15 billion by 2030—a compound annual growth rate of 33.9%.
Home lithium-ion battery systems generated USD 278.5 million in 2023 and could surge to USD 2.15 billion by 2030—a compound annual growth rate of 33.9%. Systems rated between 3 kW and 5 kW currently generate the most revenue, but smaller units under 3 kW are projected to grow faster, reflecting demand from urban households.
