DOE OE Global Energy Storage Database

The DOE Global Energy Storage Database provides research-grade information on grid-connected energy storage projects and relevant state and federal policies.
Users who download materials from this website agree to be bound by the Terms of Use and Download Disclosure.

All information is vetted through a third-party verification process. All data can be exported to Excel or PDF. Our hope is that this site will contribute to the rapid development and deployment of energy storage technologies.

As of February 18, 2020, this page serves as the official hub for The Global Energy Storage Database. We plan to update our listing of projects and policy information on a monthly basis.

Energy Storage Projects

The Global Energy Storage Database houses over 1600 energy storage projects worldwide. The entire listing of project data is available to download below:
