Oregon’s first utility-scale geothermal power plant began commercial operations Friday, its owner announced Monday.

U.S. Geothermal’s Neal Hot Springs plant, located about 15 miles west of Vale, has two of its three power modules operating continuously, generating 16 to 18 megawatts per hour. The company expects startup on the third module to begin next week, according to a news release. All electricity generated by the plant will be sold to Idaho Power, which serves Ontario, Vale, Jordan Valley, other pockets of Eastern Oregon and much of southern Idaho.
