Amec Foster Wheeler was engaged by Hudson Ranch Power 1, LLC (Owner) to provide design engineering for a 49.9 megawatt geothermal plant constructed at a project site near Niland, California. The facility was a triple flash plant using Crystallizer Reactor Clarifier (CRC) technology to process the geothermal brine and steam from the Salton Sea production wells. The plant’s electrical output was connected to the local community-owned utility,Imperial Irrigation District (IID) transmission system at 230kV. The facility will be operated via a commercially-available Distributed Control System (DCS). The plant also included an administration building and separate machine shop and warehouse.
The overall scope of this project was very diverse. The plant was subdivided into the following two main areas: the Brine Processing Facility and the Turbine Generator Facility. These areas were full of energy conservation methods to extract every possible ounce of energy from the geothermal source.This holistic approach by Amec Foster Wheeler allowed the reduction of parasitic load on the plant, making the plant more profitable for the client.
The plant was designed with installed spare capacity, redundancy, and other features to achieve an annual capacity factor of 98%. The design of systems and equipment was intended to provide maximum reliability. All rotating and condensate equipment was provided with installed spare capacity unless otherwise specified. Critical spares such as brine system control valves and critical turbine spare parts are kept in Owner’s on-site inventory.
