In a quest to cut the cost of clean electricity, power utilities around the world are supersizing their solar farms.

Nowhere is that more apparent than in southern Egypt, where what will be the world’s largest solar farm — a vast collection of more than 5 million photovoltaic panels — is now taking shape. When it’s completed next year, the $4 billion Benban solar park near Aswan will cover an area 10 times bigger than New York’s Central Park and generate up to 1.8 gigawatts of electricity.

That’s roughly the output of two nuclear power plants combined and almost double the planned capacity of the vast Villanueva facility now growing in the Mexican state of Coahuila — currently the largest facility in the Americas. (The largest solar farm in the U.S. is the 580-megawatt Solar Star facility near Los Angeles.)

For the past few months, Tesla and CEO Elon Musk have been teasing a giant battery project that would dwarf even the company’s 129 MWh Powerpack project in Australia.

Today, we learn that Tesla is working with PG&E on a massive battery system with a capacity of “up to 1.1 GWh” in California.
