Ormat Technologies unveils a geothermal design delivering 100 MW of power

US-based geothermal and renewable company Ormat Technologies has introduced a geothermal power plant design that, according to an Ormat press release (08/06/2026), would represent the largest of its kind in the industry, with the capacity to generate 100 MW of electricity from the heat of the Earth in a single autonomous unit.

According to the CEO of Ormat, “Rapidly rising electricity demand and our decades of proven operations create an opportunity unlike any we have seen before,” and he further noted that Ormat’s design, named the Ormega100, would effectively double the electrical output of its largest existing operating model.

This renewable energy technology has recently attracted attention from Silicon Valley firms seeking additional electricity supply to support their AI expansion strategies. In 2025, Google, for example, signed long-term contracts to purchase geothermal electricity from several companies, including Ormat Technologies and Fervo Energy. In addition, Meta has also entered into geothermal energy agreements with multiple power providers (Reuters, 08/06/2026).

The Ormega100 system would rely on an enhanced geothermal approach, involving the injection of water approximately one and a half miles underground in order to extract heat generated from the Earth’s core. By contrast, conventional geothermal systems depend on much shallower natural underground water reservoirs, which makes electricity production more dependent on specific geological sites compared to advanced geothermal techniques.

Ormat Technologies currently operates a total generating portfolio of 1,835 MW, which includes a 1,340 MW geothermal and solar generation portfolio distributed globally across the United States, Kenya, Guatemala, Indonesia, Honduras, and Guadeloupe, as well as a 495 MW energy storage portfolio located in the United States.
