The future of energy generation is in the Mojave Desert! Forty miles southwest of Las Vegas, just across the border in California, BrightSource Limitless, in partnership with NRG Solar and Google, constructed the world’s largest solar array comprised of three collector towers and 170,000 heliostats (reflectors) surrounding them. With a nominal output of 377 megawatts, this facility effectively doubles the amount of solar power energy in the United States.

Special 4HBP40M-S1 power winches from Thern are installed and used for maintenance operations, one winch sitting in the top of each tower. Each winch is mounted in an inverted position and features a non-standard drum able to hold enough wire rope to cover the 400 foot lift distance and a rotary limit switch.
