NV Energy made the list for the first time with a 5th place ranking, jumping 12 spots from the previous year. NV Energy's 10 MW Crescent Dunes solar energy project will use more than 17,000 heliostat mirrors to focus the sun's thermal energy to heat molten salt flowing from this 640-foot-tall solar power tower to underground storage tanks. This energy storage technology allows the generation asset to be called upon even when the sun is not shining.
