The Ivanpah Solar Electric Generating System, sprawling across roughly 5 square miles of federal land near the California-Nevada border, formally opens Thursday after years of regulatory and legal tangles ranging from relocating protected tortoises to assessing the impact on Mojave milkweed and other plants.
The $2.2 billion complex of three generating units, owned by NRG Energy Inc., Google Inc. and BrightSource Energy, can produce nearly 400 megawatts — enough power for 140,000 homes. It began making electricity last year.
Larger projects are on the way, but for now, Ivanpah (EYE’-ven-pah) is being described as a marker for the United States’ emerging solar industry. While solar power accounts for less than 1 percent of the nation’s power output, thousands of projects from large, utility-scale plants to small production sites are under construction or being planned, particularly across the sun-drenched Southwest.
The opening of Ivanpah is “a dawn of a new era in power generation in the United States,” said Rhone Resch, president of the Solar Energy Industries Association, a trade group. “We are going to be a global leader in solar generation.”
