US EditionBattery Storage Hits $65/MWh – a Tipping Point for Solar
Utility-scale battery costs dropped 40% in 2024 to $76/MWh, enabling solar power storage at competitive rates against new fossil fuel generation, Ember reported.
- On December 11, 2025, Ember released analysis showing storage costs with utility-scale batteries fell to $65/MWh as of October 2025 outside China and the US, enabling solar power delivery on demand.
- After a 40 per cent fall in 2024, manufacturing overcapacity, competition and a shift to lithium iron phosphate batteries compressed prices, Kostantsa Rangelova, Global Electricity Analyst at Ember, said.
- Based on auction results in Italy, Saudi Arabia and India, Ember assesses a full grid-connected battery capital cost at $125/kWh and finds that storage would add about $33/MWh, resulting in roughly $76/MWh total.
- Ember says solar can now be delivered as dispatchable electricity anytime, and BloombergNEF expects this to accelerate electric-vehicle adoption and larger storage deployments.
- Costs have plunged in recent years and Ember says after the steep 2024 drop, battery costs remain on track for another major fall in 2025 as record solar and wind capacity increase storage demand.

Analysis finds “anytime electricity” from solar available as battery costs plummet
Ember's report outlines how falling battery capital expenditures and improved performance metrics have lowered the levelized cost of storage, making dispatchable solar a competitive, anytime electricity option globally.A report from energy think tank Ember details how cost reductions in battery storage technology are enabling dispatchable solar power to compete with conventional power sources. Ember’s assessment draws on data from recent auction…
The cost of storing solar energy during the day for use as electricity at any time was reduced to €65/MWh by 2025, according to a new analysis by Ember. The expert group said that battery storage costs on a utility scale outside of China and the United States have continued to fall sharply this year following the sharp decline recorded in 2024.
