LAS VEGAS (AP) — Construction has begun on a $1 billion solar power generating station in the Mojave Desert that officials say will produce enough electricity to power about 80,000 California homes when it is completed in 2016.

The 250-megawatt project, dubbed Silver State South, will capture solar energy with panels spread across almost 4 square miles of federal land south of Las Vegas, according to a fact sheet obtained Friday from a First Solar Inc. representative.
