The nation's largest electric utility, Duke Energy, comes in eighth among holding companies for solar-energy capacity, the Solar Electric Power Association reports.
Duke's regulated operations have a combined solar capacity of 183 megawatts, most of it bought from other companies. San Francisco-based PG&E Corp., parent of Pacific Gas and Electric, led the list with 1,569 megawatts.
Duke Energy Progress, which serves much of eastern North Carolina, the Asheville area and parts of South Carolina, ranked eighth for the growth of its solar installations last year. It has 94 megawatts of solar capacity while Duke Energy Carolinas, serving Charlotte and the western Carolinas, has 77 megawatts. Duke has 12 megawatts of solar in Florida.
Duke Energy Renewables, an unregulated subsidiary, owns more than 100 megawatts of utility-scale solar, including 15 projects in five states. The power they produce is sold to other utilities.
