Duke Energy Renewables has doubled its PV portfolio in North Carolina by buying three systems, with a combined capacity of 3MW, from turnkey developer ESA Renewables. The Murphy Farm, Wingate and Holiness solar projects have been installed this year and each has a capacity of 1MW.

All three are located in or near to the town of Murphy, and the power generated by the portfolio is being sold through Blue Ridge Mountain EMC to the Tennessee Valley Authority as part of TVA's Generation Partners programme. In spite of the sale, ESA will continue handle operations, monitoring and maintenance at each site.

Duke’s energy portfolio in North Carolina now stands at 6MW – earlier this year it acquired 1MW systems in Shelby, Taylorsville and Martins Creek – and it will grow further when building work finishes on the 5MW Murfreesboro park.
