The 377-megawatt Ivanpah Solar Electric Generating System built by Bechtel is delivering electricity to California customers. Ivanpah is the world’s largest solar thermal facility located in the Mojave Desert of Southern California. The facility, which is a joint effort of NRG, Google, and BrightSource Energy, will produce enough clean, renewable electricity to power 140,000 homes.
Bechtel built and procured Ivanpah’s solar field, which includes 173,500 heliostats that follow the sun’s trajectory, solar-field-integration software, and a solar-receiver steam generator. The team exceeded its goal of installing 500 heliostats per day and achieved more than 800 heliostat installations per day at peak construction.
Bechtel designed, procured, and built the project’s trio of 450-foot high power towers and successfully placed 2,200-ton boilers on top of each tower. In addition, the team executed the project safely, working 31 months and 7.3 million hours without a lost-time accident.
In the last year, Bechtel has built three of the world’s largest solar facilities, including Ivanpah. In 2013, the company also completed the California Solar Valley Ranch photovoltaic project and the Catalina Solar Photovoltaic Generating Facility, also in California.
