ESS Price Forecasting Report (Q2
The ESS Price Forecasting Report is published on a quarterly basis; this report provides a five-year forecast for the price of a DC battery container, including battery cells, modules, racking,
Battery storage costs have fallen dramatically over the past two years, and the decline continues. Following a steep decline in 2024, Ember's analysis indicates that prices continued to fall sharply again in 2025.
A second year of dramatic price falls means batteries are now cheap enough to make dispatchable solar economically feasible. With the cost of storing electricity at $65/MWh, storing 50% of a day's solar generation for use during the night-time hours adds $33/MWh to the total cost of solar. The global average price of solar in 2024 was $43/MWh.
As Ember global electricity analyst Kostantsa Rangelova put it, after a 40% drop in battery equipment costs in 2024, the industry is now on track for another major fall in 2025. The economics of battery storage, she said, are “unrecognizable,” and the industry is still adjusting to this new reality.
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.
