Ormat Technologies, Inc. (NYSE: ORA) announced its subsidiary, Ormat Nevada, Inc., has completed construction of a 1 MW rated Ormat Energy Converter for the Arizona Public Service Company Saguaro Solar Facility. This is the first project to combine solar trough technology with a specially designed Organic Rankine Cycle based OEC power block, similar to the type used by Ormat in geothermal and recovered energy generation power applications.
The plant’s process consists of the sun’s energy being concentrated by parabolic mirrors in a trough formation to receivers. This concentrated solar energy heats up thermal oil, which then transfers its heat to the OEC power unit working fluid. Use of Organic Rankine Cycle technology facilitates generation of power even with fluctuating and low temperature heat.
Scott Canada, APS Project Engineer, said: “APS believes that this plant is an example of the future of energy generation and provides an excellent opportunity to continue leading the development of renewable energy in the US.”
This OEC technology has a proven track record of low maintenance and high reliability in the operation of over 800 MW of Ormat geothermal and recovered energy generation power projects worldwide.
Ormat Technologies, Inc. designs, builds, owns and operates geothermal power plants. It also designs, develops and builds, and plans to own and operate, recovered energy-based power plants.
