Geothermal Energy Funding
Geothermal Energy Secures Millions in New Public and Private Investments for Grid Support

Key Points
1
Mazama Energy says Project Ceres could generate enough electricity to power about 4,500 average households, while Deschutes County Commissioner Phil Chang said successful geothermal development could eventually make the region a net energy exporter.
2
The federal geothermal work includes Fervo Energy testing whether Nevada reservoirs reach temperatures of 200 to 220 degrees Celsius, while Oriah Geothermal will drill thermal-gradient wells in eastern Oregon to refine subsurface targets.
3
The proposed Silver Rock transmission project is described as a 330-mile line operating at between 500 and 600 kilovolts, and the Bureau of Land Management has opened a public-comment period on the proposal.
4
Texas’s proposed rules for connecting large industrial electricity users apply to projects requiring at least 75 megawatts and would require developers to show they control the project site and provide information such as load-ramping schedules and expected water use.

Revenue from energy development on Texas state-owned land would flow to the Permanent School Fund, which supports Texas public schools; the state General Land Office oversees more than 13 million acres of state land and mineral rights.
Geothermal energy is attracting hundreds of millions in public and private funding as companies race to tap superhot underground rock for reliable, low-carbon electricity. Mazama Energy has secured over $135 million to advance Project Ceres at Oregon's Newberry Volcano, while the U.S. Department of Energy is distributing $99 million across 21 geothermal projects nationwide, with leaders in Houston and Idaho competing to prove the technology works at scale.
The momentum reflects growing confidence that geothermal can help states meet surging electricity demand without fossil fuels. Texas is now soliciting proposals for geothermal plants on state-owned land, while a proposed 330-mile transmission line across Nevada and Utah could unlock access to the power grid for dozens of future projects.
Mazama's $135 Million Play in Oregon Superhot Rock
Mazama Energy, a Texas-based company, is betting big on Project Ceres at Newberry Volcano in Oregon. Mazama has raised over $135 million from venture capital firms to develop a 15-megawatt horizontal-well project by 2027. The facility is designed to generate enough electricity to power about 4,500 average households, according to Mazama's projections.
The project could transform the region. Deschutes County Commissioner Phil Chang said successful geothermal development could eventually make the area a net energy exporter—meaning it produces more power than it consumes. The Newberry site sits atop underground heat that few U.S. locations can match.
Federal Money Backs Three Companies Testing Unproven Techniques
The U.S. Department of Energy is distributing $99 million to 21 projects, with Houston-based Fervo Energy and Quaise Energy receiving nearly $45 million combined. Fervo will test whether Nevada reservoirs can reach temperatures of 200 to 220 degrees Celsius—hot enough to generate power reliably. The company is betting on a newer drilling method called horizontal wells.
Oriah Geothermal is taking a different path in eastern Oregon, drilling thermal-gradient wells to map underground heat sources more precisely. The Department of Energy is requiring all recipients to share data publicly, allowing scientists nationwide to learn from successes and failures. This collaboration could accelerate the entire industry's progress.
Nevada Transmission Line Could Connect Dozens of Future Geothermal Plants
A proposed transmission line called Silver Rock would stretch 330 miles across Nevada and Utah, operating at 500 to 600 kilovolts of power. The project addresses a major bottleneck: geothermal sites often sit far from existing power grids. Without this line, new plants have nowhere to send their electricity.
The Bureau of Land Management has opened a public-comment period on the proposal. If approved, the line could serve dozens of geothermal projects planned across the intermountain West. Nevada and Utah are among the top five states with untapped geothermal potential.
Texas Offers State Land for Geothermal and Nuclear Projects
Texas is opening more than 13 million acres of state-owned land for geothermal, small modular nuclear, and natural-gas projects. The state's General Land Office is soliciting proposals from developers who can demonstrate they control their project sites and meet strict requirements. Projects must be at least 75 megawatts to qualify.
Revenue from successful projects flows to the Permanent School Fund, which finances Texas public schools. This setup gives the state financial incentive to approve projects while filling its education budget. It's a bid to meet rising electricity demand without relying on coal or natural gas alone.
