Sage Geosystems Selects Ormat’s Blue Mountain Power Plant for Next Commercial-Scale EGS Facility

Sage Geosystems (“Sage”), a U.S.-based Enhanced Geothermal Systems (EGS) power developer, today announced that it has selected Ormat Technologies’ Blue Mountain geothermal power plant in Winnemucca, Nevada, as the location for its next commercial-scale EGS facility, Project Vector. The two-well system will use Sage’s proprietary EGS technology to deliver firm, reliable geothermal heat to Ormat’s Blue Mountain power plant, where it will be converted into electricity to help serve residential, industrial and data center demand in the region.

Sage expects to begin drilling the first of two wells in the fourth quarter of 2026, with first electricity produced in 2027 and full-scale production in 2028, subject to permitting and regulatory processes. The site was selected based on available power plant capacity, favorable subsurface geology, and access to existing power infrastructure. By leveraging Blue Mountain’s established assets, Sage can direct its capital, resources and strategic focus toward demonstrating the performance of its proprietary EGS system and validating a development model designed to deliver higher net power output with significantly lower water losses than other EGS systems.

Project Vector builds on the operating experience and field validation from Sage’s SMECI facility in South Texas, where the company demonstrated critical subsurface performance that was repeatable, consistent, and predictive over more than 120 days of operations. Those learnings, together with Sage’s GeoTwin™ digital twin platform, are being applied to the design and development of Project Vector. This will further improve confidence in expected subsurface performance and reduce uncertainty as Sage advances into another geologic setting and towards scaled projects, demonstrating that its EGS approach can be replicated across different resource settings with confidence. The development of Project Vector supports Sage’s growing commercial pipeline, including its 150 MW geothermal power agreement with Meta, and reflects increasing customer demand for dependable, 24/7 geothermal power.

“Blue Mountain is an ideal location for Sage to take the next step in continuing to commercialize our proprietary EGS approach,” said Jason Peart, Chief Operating Officer of Sage Geosystems. “By delivering geothermal heat into an existing power plant, Project Vector can demonstrate the model for bringing firm, 24/7 geothermal power to market at scale.”

Project Vector also builds on Sage’s growing strategic relationship with Ormat. In August 2025, Sage and Ormat entered into a strategic agreement focused on accelerating the commercialization of Sage’s geothermal technology at an existing Ormat power plant. In January 2026, Ormat co-led Sage’s ~$100 million Series B financing, further expanding the relationship and supporting development of Sage’s next commercial geothermal power generation project.

Sage’s proprietary EGS approach is designed to engineer and actively manage the subsurface as a controlled energy system. In Project Vector’s two-well system, fluid will circulate through an engineered subsurface reservoir, absorb heat from the surrounding rock, and return to the surface, where that heat will be delivered to the Blue Mountain plant for conversion into electricity. Its recent demonstration at SMECI, with over 120 days of operations, proves that Sage can engineer a repeatable reservoir and predict field operating behavior using its GeoTwin™ modeling tool, a digital twin that reduces uncertainty in future project performance. Sage’s approach is designed to minimize water and energy losses, increase net power output, and improve predictability, enabling firm, reliable, 24/7 geothermal generation across a broader range of geologies.
