Client: Mitsubishi Heavy Industries
Location: Rift Valley, Kenya
In 2000, Mitsubishi Heavy Industries was awarded the EPC contract to develop the 64 MW two-unit Olkaria II geothermal project, funded by KenGen in conjunction with a loan from the World Bank. The power plant is a crucial baseload contributor to the Kenya national power supply. POWER was awarded the contract for mechanical piping and instrumentation and control system design for the new plant, an effort that involved close coordination with MHI’s electrical engineering and construction contractors. POWER also coordinated mechanical and piping design with the Kenyan civil/structural design contractor.
POWER’s scope included preparation of specifications, solicitation of bids, vendor selection, and initiation of procurement and expediting of major equipment including NCG equipment, steam dryers, pumps, control valves, cooling towers, and plant instrumentation. Other services included conceptual design and EPC bid development, mechanical and I&C design for the geothermal plant, mechanical balance of plant equipment specification and procurement, steamfield communication and control system and construction support.
In 2007, POWER again teamed with MHI to add a third turbine-generator unit to the Olkaria II plant. The project required engineering services to design the expansion of the powerhouse and plant ancillary services and installation of the new turbine-generator. The design also included an expansion of the existing 220 kV substation and design of controls for the generation plant and steamfield facilities. POWER’s scope also included preparation of specifications, solicitation of bids, vendor selection, and initiation of procurement and expediting of major equipment.
