Thermal Zones™ is your definitive source for the status and ownership of geothermal power zones.

Thermal Zones™ provides data on the locations and status of geothermal energy zones on public land. The Bureau of Land Management (BLM) grants individuals and companies geothermal power leasing rights on public land. Thermal Zones™ is a source to see where these geothermal energy zones are and have been.

A Shifting Landscape

New claims are being filed, auctioned, or resold through private sales. While claims change hands, become active or closed, or have new actions filed, we are updating our records to make this information available to everyone.

We are changing too. Thermal Zones™ is constantly updating and refining content to make it easier to access and add new, useful features for our users. Have an idea of what you would like to see or explore business opportunities? Contact us!

Green Energy resources for everyone

The BLM also leases land for a wide variety of other green energy generation types. We share information on public solar energy claims through Solar Energy Zones™ and public wind energy claims through Wind Energy Zones™.
