Ormat Technologies outlines expanded geothermal exploration, emphasizes high capacity factor and low emissions
Summary
Ormat Technologies told Churchill County commissioners it is exploring seven new sites locally, described differences among low/medium/high‑temperature geothermal systems and said binary‑cycle plants offer near‑zero direct emissions and high capacity factors; company representatives outlined multi‑year development timelines and local community benefits.
Scott Nichols, senior representative for Ormat Technologies, updated the Churchill County Board of Commissioners on the company’s local geothermal operations and exploration activity.
"Churchill County is really ground zero for the geothermal industry," Nichols said, listing existing plants and capacities: Brady Desert Peak (~24 megawatts), Dixie Valley (~64 megawatts), Stillwater (~12 megawatts), Tungsten (~38 megawatts) and Salt Wells (~9 megawatts). He said Ormat is exploring seven new sites ranging from Juniper Mountain to Diamond Flat and New York Canyon and has been core‑drilling at Diamond Flat this week.
Nichols framed geothermal resources by temperature and technology: low‑temperature direct‑use systems (hot springs, ground‑source heat pumps), medium‑temperature binary‑cycle plants (the company’s core business, he said), and high‑temperature flash‑steam operations found primarily in parts of California. He said binary plants use a closed loop with working fluids such as isopentane/isobutane and produce "zero direct emissions" from the power cycle.
Nichols emphasized geothermal’s high capacity factor compared with wind and solar. "When Ormat ... develops a 25‑megawatt geothermal power supply ... that resource when developed will deliver the design capacity 95 to 99% of the year," he said, arguing geothermal is a reliable baseload resource. He also warned that geothermal development timelines are long and risky: while permitting recently sped up, he said it can still take "three to five years" to bring a resource to the grid and that some sites (Diamond Flat) have taken more than five years to reach core drilling.
On community impacts, Nichols said Ormat expects relatively small long‑term local workforce needs ("four to 20" operational positions depending on the project, with larger but temporary construction crews), minimal surface or groundwater impacts for power production (water is used for drilling but not in the production cycle), an approximate land footprint of about one acre per megawatt, and ongoing coordination with ranching and agricultural operations.
He cited local fiscal contributions, saying Ormat pays "over $6 million annually" in Churchill County taxes and mentioned a "25% federal royalty payment kickback" though he offered to verify the exact royalty figures if the board wanted. Nichols closed by offering to return with further updates as exploration advances.
The presentation drew brief thanks and no substantive public comment; staff and commissioners did not take further action on the information item.
