The contract is valued at more than $14m and the project is scheduled for completion by January 2012.
The power plant will be constructed adjacent to the existing Dixie Valley geothermal facility.
Work will be performed by The Benham Companies, SAIC’s wholly owned, design-build subsidiary.
SAIC senior vice president and business unit general manager JT Grumski said that the company looks forward to delivering a quality facility to Terra Gen, and further demonstrating its expertise in the geothermal renewable energy market.
