Centinela Solar Energy Project, California

Centinela is one of a few large photovoltaic power plants in the southwestern Imperial Valley, west of Calexico, California. Construction started in 2012, and it has at least a 170 megawatt capacity. It was built by Fluor and the LS Power Group, at a cost of around $1.8 billion. It is adjacent to the Tanaska Solar Plant, and near the Mount Signal Solar Power Plant. Like the others, it provides power to San Diego, through the Sunrise Powerlink, a 117 mile-long 500 volt line put into service in 2012.
