Two pilots have filed safety reports with NASA’s ASRS system about the recently opened Ivanpah solar energy plant in San Bernardino County, Calif. The pilots said they were nearly blinded by the glare off the energy plant’s expansive mirror system. The Ivanpah plant uses 173,500 large mirrors to reflect sunlight onto boilers atop three 459-foot towers. Ivanpah’s co-owner and operator, NRG Energy, was notified of the “blinding” complaints last week and said it would respond within 10 days.
