MANY MINDEDTexas geothermal pilot achieves 120+ days of stable grid connection
Sage Geosystems operates a 3-megawatt next-generation geothermal pilot plant in San Antonio, Texas, which has been grid-connected for over 120 days since April 2026. This project represents the third next-generation geothermal system in the U.S. connected to the electrical grid. The facility uses enhanced geothermal technology: it drills deep into hot rock formations and fractures them to create water pockets that generate heat for electricity. During multiple operational cycles, the system reported less than 10% water loss—a critical efficiency metric for arid regions. Sage plans to begin drilling at Ormat Technologies’ Nevada facility later this year (2026), with full-scale commercial production expected by 2028. The company also has a planned collaboration with Meta for 150 megawatts of next-generation geothermal power development east of the Rocky Mountains and has lined up approximately 1 gigawatt of next-generation projects.
This pilot demonstrates scalable geothermal energy production without the water-intensive limitations of conventional systems. For communities reliant on grid electricity, it suggests a path to cheaper, more reliable clean power—especially as the technology advances from pilot scale to commercial deployment. The water efficiency and grid stability metrics indicate potential for wider adoption in regions facing energy scarcity or water stress.
What to watch: The Nevada drilling timeline and whether the Meta collaboration accelerates the 150-megawatt project. Caveats: Water loss figures are from multiple operational cycles in the Texas system; the Nevada drilling is described as a 'necessary precursor' to the Meta project, meaning full-scale deployment remains pending.
