Southern Company subsidiary Southern Power, in partnership with Turner Renewable Energy, began commercial operation on the Spectrum Solar Facility, located in Clark County, Nevada. The 30-MW solar PV installation utilizes tracking technology that enables greater efficiency by directing solar panels to track the sun as it moves across the sky. The 311-acre site was built and will be operated and maintained by SunEdison. Southern Power and Turner Renewable Energy acquired the project from SunEdison in September 2012. Electricity generated by the Spectrum Solar Facility will serve a 25-year PPA with Nevada Power.
