California is expected to soon meet about 10 percent of its peak power demand with energy from the sun. There are more than 5,774 MW of solar energy projects operating and under construction. The worst case statewide power demand based on the hottest day that\u2019s likely to occur every 2 years is 59,571 MW. The completion of the solar projects under construction would result in sun-powered systems meeting 9.7 percent of that demand. On hot sunny afternoons solar also would produce more electricity for California than the three nuclear power plants that currently serve the state. When fully operational, those plants make 5,444 MW of power for the state\u2019s utilities. There are 705 MW of utility-scale solar projects online, as well as another 1,060 MW of small-scale capacity on the customer side of utility meters. In addition, there are 3,598 MW of utility-scale projects under construction, including 228 MW of projects under 100 MW in capacity. The huge solar projects are being built in phases and will take years to complete. There are more than 411 MW of small-scale solar projects being installed on utility customer premises. The data are drawn from the Solar Energy Industries Association, California Energy Commission, and California Public Utilities Commission.
