The plant, Ivanpah Solar Electric Generating System, which is being developed by BrightSource Energy, will generate 392 MW of clean, solar energy when completed in 2013, Google said.
The power would be sufficient to supply power to 85,000 homes a year.
"That's the equivalent of taking more than 90,000 cars off the road over the lifetime of the plant, projected to be more than 25 years," Google's director of green business operations Rick Needham said in a blog post.
The BrightSource investment, which puts the company's investment in clean energy projects to $250 million, makes business sense and will help ensure that one of the world's largest solar energy projects is completed," Needham said.
Meanwhile, the US Department of Energy said it has finalised $1.6 billion in loan guarantees to support the Ivanpah Solar Energy Generating System.
"Today's announcement is creating over 1,000 jobs in California while laying the foundation for thousands more clean energy jobs across the country in the future," US Energy Secretary Steven Chu said.
"Through the loan program we are supporting some of the largest, most innovative clean energy projects in the world, and those investments are helping us to out-compete and out-innovate
