- Utility-scale battery storage costs have fallen to $65 per MWh outside China and the US as of October 2025.
- Pairing solar with batteries is now economically viable, making solar power dispatchable at night.
- Battery storage system costs for long-duration projects (4+ hours) are about $125/kWh outside China and the US.
- Lower upfront costs, longer battery lifetimes, higher efficiencies, and clearer revenue models have reduced LCOS.
- Shifting half of daytime solar to nighttime adds about $33/MWh, bringing total solar + storage cost to ~$76/MWh.
- Battery equipment costs dropped 40% in 2024, with another major decline expected in 2025.
- Solar + storage is becoming a scalable, secure, and affordable foundation for future power systems.
