Ormat Technologies
Ormat Technologies, founded by the Bronicki family, owns 32 geothermal plants and sells binary-cycle turbines to projects on five continents.
Ormat Technologies
Ormat Technologies traces its origin to 1965, when Israeli engineers Yehudit and Dita Bronicki started a company in Tel Aviv to build turbine-based power systems. The firm’s early breakthrough—a binary-cycle turbine that generates electricity from moderate-temperature geothermal brine—defined a category it still leads. Ormat moved its corporate headquarters to Reno, Nevada in the 1980s, aligning with the Great Basin’s rich geothermal resources. Today the firm operates across two segments: Electricity, where it owns and runs 32 geothermal and recovered-energy plants in the United States, Kenya, Guatemala, Guadeloupe, Honduras, and Indonesia; and Product, where it sells turbines and engineered solutions to geothermal, waste-heat, and solar-thermal projects worldwide. The Electricity segment is the core revenue driver, delivering predictable cash flows under long-term power purchase agreements with utilities and community choice aggregators. Ormat’s plants represent roughly 1.3 GW of gross capacity, with the largest concentration in Nevada and California. The Product segment supplies binary-cycle equipment to developers in Turkey, New Zealand, and East Africa—regions where state-backed drilling programs have expanded geothermal potential. The firm also operates recovered-energy generation units that capture waste heat from gas pipeline compressor stations. This dual structure—asset-heavy utility operations combined with an export-oriented manufacturing business—creates a capital-recycling flywheel: product revenue funds early-stage development, and stabilized plants generate the balance-sheet strength to finance new construction. Ormat employed over 1,400 people at its 2023 year-end filing and maintains its primary technology campus in Yavne, Israel, alongside its Reno headquarters. The Bronicki family retains significant influence: Dita Bronicki served as CEO until 2015, and Isaac Angel, appointed in 2016, continues to lead the firm through a growth phase targeting 1.9–2.0 GW of owned capacity by 2025. In August 2023, Ormat closed the acquisition of a geothermal portfolio from Enel Green Power North America, adding operational plants in Nevada and Utah alongside development-stage assets, for $271 million (per the firm, August 2023). The company has also expanded into energy storage, developing hybrid geothermal-solar-plus-battery projects in California to meet post-sunset demand. What structurally differentiates Ormat from other energy operators is its control of the IP stack beneath every plant. Because the firm manufactures its own turbines and holds the patents on binary-cycle technology, it avoids the procurement bottlenecks and royalty costs that constrain competitors relying on third-party equipment. This vertical integration—from metallurgy in Yavne to operation of wells in the Rift Valley—makes Ormat simultaneously a manufacturer, a developer, and a utility, an unusual combination that distances it both from pure-play independent power producers and from turbine OEMs with no owned generation.

Frequently asked questions
Who controls Ormat Technologies?
Ormat is a publicly traded company (NYSE: ORA) with significant ongoing influence from the Bronicki family. Yehudit (Dita) Bronicki co-founded the firm in 1965 and served as CEO until 2015. Her husband Lucien (Dita) Bronicki led the technology development. The family, through related trusts and entities, remains a substantial shareholder. Day-to-day executive leadership sits with CEO Isaac Angel and CFO Doron Blachar.
Does Ormat only operate geothermal plants, or does it sell equipment to third parties?
Ormat runs two segments. The Electricity segment owns and operates 32 geothermal and recovered-energy generation plants. The Product segment designs, manufactures, and sells binary-cycle geothermal turbines and associated power plant equipment to third-party developers. Customers include state-owned utilities in Turkey and New Zealand, as well as private developers in East Africa and Southeast Asia.
Which geographies represent Ormat's largest owned-asset exposure?
The United States accounts for the majority of Ormat’s owned generating capacity, with the heaviest concentration in Nevada and California. Internationally, the firm owns and operates plants in Kenya, Guatemala, Guadeloupe, Honduras, and Indonesia. Kenya represents the largest single international market, where Ormat supplies power to Kenya Power under long-term PPAs.
How does Ormat's binary-cycle technology differ from conventional geothermal steam turbines?
Conventional geothermal plants require high-temperature steam directly from the reservoir. Ormat's binary-cycle systems pass geothermal fluid—often at temperatures as low as 200°F—through a heat exchanger to vaporize a secondary working fluid with a lower boiling point. That vapor drives the turbine while the geothermal fluid remains in a closed loop and is reinjected underground. This allows economic generation from a much wider range of geothermal resource temperatures.
Is Ormat expanding beyond geothermal into other forms of generation or storage?
Yes. Ormat has developed hybrid solar-geothermal facilities and is integrating battery storage at several California sites. The firm also operates recovered energy generation units that capture waste heat from natural gas pipeline compressor stations. In 2023, management signaled that energy storage projects would become a growing portion of the development pipeline, leveraging land and interconnection positions at existing geothermal sites.
Does Ormat hold the patents on its turbine technology?
Ormat holds extensive patents covering binary-cycle turbine design, heat-exchanger configurations, and power plant control systems. Because the company designs and manufactures equipment in-house at its Yavne, Israel facility, it retains full intellectual property control and avoids third-party licensing fees on its owned plants.
What is Ormat's relationship with the Bronicki family?
The firm was founded by Yehudit Bronicki and her husband Lucien Bronicki in 1965. Yehudit served as CEO for five decades before transitioning the role in 2015. Lucien led technical development. The family maintains a significant ownership stake and board influence, though day-to-day management now sits with a professional executive team led by Isaac Angel.
