Document Description
Applicant proposes to upgrade the existing Heber 1 geothermal facility, by shutting down the dual-flash steam turbine generator, and installing two new OECs (OEC 1 and OEC 2), reconfiguring two of the existing OECs (OEC 11 and OEC 13), including the installation of ancillary equipment and two (2) 10, 000 gallon isopentane tanks. OEC 1 and 2 combined would function as an Ormat Integrated Three-Level Unit (I3LU) and will use air cooling rather than water cooling for the motive fluid. OEC 11 and OEC 13 combined would function as an Integrated Two-Level Unit (ITLU) and will use the existing cooling tower. Applicant is also proposing to modify the permitted water intake from 1,800 acre feet of irrigation water to the existing water intake of 2,300 acre feet of irrigation water. The purpose of the repower project is to improve efficiency of the operations and increase the net and gross generation to 52MW (net), 78.2 (gross) as initially requested under Conditional Use Permit #15-0013. This proposed project also proposes to extend the permitted life of Heber 1 to 30 years (2021-2051).
