PG&E hopes to capture solar power from space by 2016

California utility Pacific Gas & Electric Co. is looking to outer space to find a new source of solar power to generate cheaper and cleaner electricity.

PG&E Monday announced that it is seeking approval from state regulators to sign an agreement to purchase power from Solaren Corp., a Manhattan Beach, Calif.-based company that promises to generate energy using solar panels that will be launched into Earth's orbit. Eight-year-old Solaren has contracted with the utility to deliver 200 megawatts of clean, renewable power over a 15-year period, according to PG&E.

Gary Spirnak, CEO of Solaren, said in a blog post that the company expects to begin generating space-based solar power for PG&E by 2016.

"Why would anyone choose so challenging a locale to generate electricity? For one, the solar energy available in space is eight to ten times greater than on earth," wrote PG&E in a company blog. "There's no atmospheric or cloud interference, no loss of sun at night, and no seasons. That means space solar can be a baseload resource, not an intermittent source of power."

Solar power, if not actually space-based solar power, has been the focus of much research in recent years. The push to bypass the use of expensive, nonrenewable energy from foreign sources has spurred research into solar-powered cars that can run all day long and studies of technology that would turn windows in large buildings into solar panels.

PG&E reported that its plan is to convert the power collected in the space-based solar panels into radio frequency energy that will then be transmitted to a receiving station in California. At that point, the energy will be converted into electricity and moved into the San Francisco-based utility's power grid.
