Project Description

Ormesa, LLC (Ormesa) has submitted an application to the BLM requesting to add a new Ormat Energy Converter (OEC) generating unit to the two existing OEC units to create an Integrated 3 Level Unit (I3LU). The new OEC unit would add a net generation of an additional 4.23 MW to Ormesa I. The new OEC would consist of one generator and one turbine on existing disturbance in an area currently authorized by BLM for the project. It would be built in an area where foundations currently exist. The foundations would be removed and rebuilt for the new unit. 
The additional OEC unit at Ormesa 1 will use an approximate 97,440.5kg of additional isopentane as the working fluid. The isopentane would be loaded directly into the new OEC unit, no new tanks would be required. It will consist of preheaters, vaporizers, turbine and generator, condensers, working fluid pumps and piping. Associated ancillary equipment will include utilizing the existing working fluid storage facilities, working fluid vapor recovery systems, and fire protection systems (including isopentane gas detectors, ultraviolet/infrared flame detectors and a fire water system).
