Ormat unveiled the Ormega100, a 100MW modular binary unit built for unmanned operation with turbine efficiency over 90% and a generator-turbine design that cuts project timelines by roughly 30%. The firm launched two EGS pilots with SLB and Sage Geosystems and reported record Q1 performance, 1,140MW installed capacity at end-2025.
Ormat's Ormega100 is a 100MW binary surface power unit engineered from a blank sheet for standardization, featuring a modular configuration pairing one generator with two turbines. This uniform design aims to slash project timelines by roughly 30% compared with bespoke plants.
The Ormega100 is built for fully unmanned operation during normal cycles, managed via a centralized remote control room with dedicated maintenance crews dispatched as needed. Major maintenance intervals are designed around once per decade, boosting reliability and reducing staffing costs.
Under its enhanced geothermal system strategy, Ormat has launched two subsurface EGS pilot programs in partnership with SLB and Sage Geosystems sited at existing facilities. These pilots aim to de-risk technology before large-scale deployment and feed energy directly into standing power plants.
The company reported a record first-quarter performance while operating 1,140MW of installed geothermal capacity at end-2025 across global assets. Its vertically integrated structure, self-funding model and six decades of plant ownership underpin its measured growth approach.
