Duke Energy Carolinas LLC applied Nov. 23 to the North Carolina Utilities Commission for an amendment of the Certificate of Public Convenience and Necessity issued on May 16 authorizing the construction and completion of a 59.4 MW (ac) solar photovoltaic facility.
The facility will be built near the corner of S. Rocky River Road and Doster Road in Monroe, Union County, North Carolina. The facility (now referred to as the Monroe Solar Power Plant by DEC) has a recorded maximum capacity of 59.4 MW (ac).
DEC determined this original capacity based on the fact that the site’s inverters were a new model and were rated by the manufacturer preliminarily at 2.475 MW (ac). There are 24 inverters at the facility. Upon final Underwriters Laboratories certification of the site’s inverters, the manufacturer uprated them to 2.5 MW (ac). Therefore, in recognition of this updated inverter capacity, DEC requests that the recorded maximum capacity of the facility be increased to 60 MW (ac), which represents 24 inverters at 2.5 MW (ac) each.
The utility noted: “This requested uprating from 59.4 MW (ac) to 60 MW (ac) does not require any additional construction or costs to DEC with respect to the output of the Facility and in fact will make the Facility more cost-effective to DEC and its customers than as determined by the Commission in granting the original CPCN.”
Duke Energy (NYSE: DUK) on May 16 had announced North Carolina commission approval to build 75 MW of new solar energy at two projects in Davie and Union counties. One is the Monroe facility, with Strata Solar to design and build the project. The other is 15.4-MW Mocksville Solar Facility in Davie County, with Crowder Construction being the project engineering, procurement and construction lead.
Both projects will be owned and operated by Duke Energy Carolinas and will help meet North Carolina’s Renewable Energy and Energy Efficiency Portfolio Standard.
