WEBBERVILLE, Texas (KXAN) – The switch was flipped Friday morning in Webberville on what officials are calling the nation’s largest solar farm.

The farm’s 127,000 solar panels blanket some 380,000 acres about 20 miles east of Austin. The panels are designed to rotate with the sun to maximize the energy production.

Officials said the farm should generate enough electricity to power about 5,000 homes. Austin Energy will purchase all of the 30 megawatts of power this farm will produce every year.

The cost is about $10 million a year for the next 25 years. That translates into about 60 cents being added onto your bill every month.
