Client: Abengoa Solar Inc.
Construction Cost:
Abengoa Mojave Solar Project is a nominal 250 megawatt (MW) solar electric generating facility located near Harper Dry Lake in an unincorporated area of San Bernardino County approximately halfway between Barstow, CA and Kramer Junction, CA.

The facility implements well-established parabolic trough technology to solar heat a heat transfer fluid (HTF). This hot HTF generates steam in solar steam generators, which expands through a steam turbine generator to produce electrical power from twin, independently operable solar fields, each feeding a 125-MW power island. The sun provides 100% of the power supplied to the project through solar-thermal collectors; no supplementary fossil-based energy source (like natural gas) is proposed for electrical power production.

RMA Group provided geotechnical observation and testing, and special inspection and testing of the structural elements of the new facility. The construction of the project required welding of thousands of connections for the network of pipelines used to carry the heat transfer fluid and steam to the turbine generators. RMA Group provided continuous welding inspection for all of these connections and radiographic x-ray examination of completed welds to ensure safe operation of the plant.
