Ormat Technologies and Nevada Geothermal Power Execute EPC Contract for Blue Mountain Faulkner 1 Power Plant

Nevada Geothermal Power Inc. (NGP) (TSX VENTURE: NGP)(OTCBB: NGLPF) and Ormat Technologies Inc.'s (NYSE: ORA), subsidiary Ormat Nevada Inc. announced today that NGP Blue Mountain I LLC (NGP I) has entered into an Engineering, Procurement and Construction Contract (EPC) for a 49.5 MW power plant, consisting of three Ormat Energy Converters (OEC's) at Blue Mountain's geothermal project in Nevada. The plant design incorporates Ormat's proprietary power generation technology with water-cooling for maximum efficiency.

The total EPC contract value is US$76 million, of which a US$20 million was previously released under a Limited Notice to Proceed (LNTP) in order to secure the guaranteed substantial completion date of December 31, 2009. The full release under the EPC contract is subject to finalizing the financing for the project and is expected to occur by April 30, 2008. The EPC provides for an additional partial release if necessary.

The EPC consists of three Ormat Energy Converter units which are guaranteed to produce 16.5 MW (gross) each, totaling at least 49.5 MW (gross). The output of the power plant at Blue Mountain will meet the Phase 1 power delivery requirements of the existing 20-year Power Purchase Agreement between NGP and Nevada Power Company with a reserve of excess power. NGP is currently in discussions with Nevada Power Company for a Phase II power contract covering the reserve power.

"The EPC contract with Ormat increases the power output of each OEC unit to 16.5 MW from the originally planned 12.5 MW. The increased OEC capacity results in a lower cost per MW installed at Blue Mountain. Ormat's proven power plant technology combined with Blue Mountain's favourable reservoir chemistry will extract more megawatt-hours of energy per unit volume of geothermal fluid compared to other available technologies, maximizing the overall megawatt potential for the Blue Mountain geothermal field," stated Brian Fairbank, President and CEO of Nevada Geothermal Power Inc.

"We are pleased for the opportunity to work with NGP's development team and are delighted to contribute from our experience and knowledge in this field. Our technology is perfectly suited for the Blue Mountain resource and we are looking forward to delivering on schedule a great performing power plant," said Dita Bronicki, CEO of Ormat Technologies Inc.
