en.Wedoany.com Reported - Ormat Technologies has launched the Ormega100 power unit, rated at 100 megawatts (MW, gross), with turbine efficiency reportedly exceeding 90%, designed for fully unmanned operation. The company calls it "the industry's largest binary surface power unit."

Amid rapid growth in electricity demand, most geothermal companies focus on accelerating drilling speeds, while Ormat, which has operated geothermal power plants for 60 years, shifts its focus to standardizing plant equipment itself. Daniel Moelk, Executive Vice President of Subsurface, Drilling, and Next Generation Technology, stated that customized plant construction is costly and time-consuming, while standardized units can shorten delivery times, improve reliability, and reduce operation and maintenance costs. The Ormega100 is self-designed, featuring a modular configuration (one generator paired with two turbines), which can reduce project timelines by approximately 30%, with overhaul cycles set at once every ten years. The unit is designed for fully unmanned operation, managing multiple plants through a remote control room and dispatching dedicated centralized maintenance teams as needed. The Ormega100 is insensitive to resource type and is suitable for hydrothermal, enhanced geothermal systems (EGS), or closed-loop systems.

Regarding enhanced geothermal systems, Ormat adopts a cautious strategy. The company is collaborating with SLB and Sage Geosystems on two pilot projects, located within existing Ormat facilities, so that energy generated from the pilots can be directly integrated into established plants, which absorb excess electricity, thereby reducing technical risk. Moelk stated that the company aims to further validate the technology before undertaking larger-scale projects, and once the pilots achieve their targets, it will deploy "very large-scale" EGS projects. There is currently no specific timeline for the first Ormega100 site.

Ormat is the largest geothermal operator in the industry, with 1,140 MW of installed capacity and approximately 500 wells as of the end of 2025, covering project initiation, land and water rights, grid interconnection, geoscience, drilling rigs, manufacturing, and operations. In the first quarter of 2025, the company reported record revenue of $403.9 million, up 75.8% year-over-year, with adjusted EBITDA of $194.9 million. On the commercial side, the company has signed approximately 200 MW of new power purchase agreements (PPAs), including a portfolio PPA of up to 150 MW with Google and a 20-year agreement with Switch in Nevada.

Moelk noted that slow permitting approvals and aging grid infrastructure are major challenges for scaling the geothermal industry. He believes permitting departments are "understaffed," and the grid system needs upgrades to support centralized gigawatt-scale power generation. He emphasized that the company funds growth through its existing profitable operations, allowing it to focus on technology development rather than capital raising.
