Ormat has introduced a 100 MW binary power generation unit designed for enhanced geothermal systems, alongside ongoing EGS pilot projects in the United States.
During the opening session of the World Geothermal Congress 2026 that started today in Calgary, Canda, Ormat Technologies announced a new 100 MW surface power generation unit designed for enhanced geothermal system (EGS) applications, as the company seeks to accelerate the commercial deployment of next-generation geothermal projects.
The new unit, called the Ormega100, was unveiled alongside an update on Ormat’s EGS strategy and pilot developments. The company describes the Ormega100 as the largest binary geothermal power generation unit currently available, designed to operate in the higher-temperature conditions expected from future EGS developments.
The announcement comes amid growing interest in geothermal energy as utilities, technology companies, and data centre operators seek reliable sources of carbon-free electricity to meet rising power demand.
Ormega100 targets utility-scale geothermal projects
According to Ormat, the Ormega100 is designed to deliver up to 100 MW of generation capacity through a single autonomous binary power unit. Binary geothermal technology uses a secondary working fluid to generate electricity from geothermal heat and is commonly deployed in low- to medium-temperature geothermal resources.
The company said the new platform is intended to bridge subsurface EGS developments with large-scale power generation infrastructure, allowing projects to move from resource development to electricity production more rapidly.
“Rapidly rising electricity demand and our decades of proven operations create an opportunity unlike any we have seen before,” said Doron Blachar, Chief Executive Officer of Ormat.
“As an established geothermal company with tangible end-to-end capabilities across the entire geothermal value chain, we have a distinct competitive advantage to commercialize and scale next-generation geothermal solutions reliably.”
Two EGS pilot projects underway
Alongside the introduction of the Ormega100, Ormat confirmed that it is advancing two EGS pilot programmes aimed at evaluating technologies that could expand the deployment of geothermal energy beyond conventional hydrothermal resources.
The company did not disclose additional technical details or locations for the pilot projects but stated that the initiatives combine its geothermal development experience with emerging EGS technologies.
Ormat currently operates approximately 1,835 MW of generation and energy storage capacity globally, including around 1,340 MW of geothermal and solar generation assets. The company also holds roughly 400,000 acres of geothermal leases across six U.S. states.
Positioning for the next phase of geothermal growth
The announcement highlights Ormat’s increasing focus on enhanced geothermal systems, a segment attracting significant attention from investors and technology companies due to its potential to unlock geothermal resources in regions without naturally permeable reservoirs.
While several companies are pursuing EGS technologies through various drilling and reservoir stimulation approaches, Ormat is positioning itself as a developer capable of integrating both subsurface development and surface power generation within a single business model.
Founded more than 60 years ago, Ormat remains one of the world’s largest geothermal operators and equipment suppliers, with approximately 3,600 MW of geothermal and recovered energy generation capacity either installed or owned worldwide.
