The company Daybreak Power has proposed a 2,210-megawatt facility near the south shore of Lake Powell. It’s dubbed the Navajo Energy Storage Station. According to the company, it would use solar and wind energy to pump lake water to a 6-billion-gallon upper reservoir and then release it, generating 10 hours of electricity daily. The project would include a 131-foot concrete dam and other infrastructure. The $3.6 billion project would also utilize power lines left from the now-closed Navajo Generating Station to deliver electricity to Arizona, Nevada and Southern California.

The Federal Energy Regulatory Commission accepted Daybreak Power’s preliminary application last week.

A separate Phoenix-based company last year filed initial paperwork for two hydro-storage projects on the Little Colorado River that would include four dams and four reservoirs.
