How much does a battery energy storage system cost?

Ember provides the latest capex and Levelised Cost of Storage (LCOS) for large, long-duration utility-scale Battery Energy Storage Systems (BESS) across global markets outside China and the US, based on recent auction results and expert interviews. 1. All-in BESS projects now cost just $125/kWh as of October 2025 2.

What are storage costs?

Storage costs are overnight capital costs for a complete 4-hour battery system. Figure 9. Comparison of cost projections developed in this report (solid lines) against the values from the 2023 cost projection report (Cole and Karmakar 2023) (dashed lines). Figure 10.

Are battery storage costs based on long-term planning models?

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.

Do projected cost reductions for battery storage vary over time?

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).
