US Geothermal Tax Credits in 2026: What Is Actually Still Alive After OBBBA For an industry that spent more than a decade building financial models around a stable federal incentive structure, 2026 has been a year of whiplash. The 30% federal geothermal tax credit that developers and homeowners built forecasts around is gone in one form and still alive in another, and even the IRS’s own public guidance has been confusing enough to trigger uncertainty across the market. That confusion is not a minor clerical issue. It is shaping investment decisions, contractor sales pitches, homeowner timelines, and project finance assumptions right now. If you work in geothermal, the key question is no longer whether federal incentives exist, but which incentive applies, to which project type, and under what ownership structure. The law that changed the timeline To understand where things stand in 2026, you have to start with the Inflation Reduction Act of 2022, which created a long runway for clean e...
Utah FORGE Begins Extended Circulation Utah FORGE has launched an extended circulation test at its Milford, Utah field site, marking a major step forward in the development of enhanced geothermal systems. The new phase is designed to examine how the reservoir behaves during continuous operation and to generate the long-term performance data needed to evaluate commercial viability. For a project focused on de-risking geothermal technology, this is one of the most important milestones yet. Introduction Utah FORGE, the world’s only full-scale field laboratory dedicated to testing and improving the technologies required for enhanced geothermal systems , has entered a new extended circulation phase at its site approximately 10 miles northeast of Milford, Utah. The test is expected to run for roughly four months, with the possibility of extending to 120 days depending on operational conditions. This stage matters because geothermal development is not only about finding heat underground; it i...
