Duke seeks approval for interconnect to NTE’s Kings Mountain power project

Duke Energy Carolinas LLC on Jan. 27 filed with the North Carolina Utilities Commission a letter of intent to file for a waiver of the notice and hearing requirements related to a power line interconnect needed for the NTE Carolinas LLC power project to the Duke grid.

In order to connect a new generating facility to Duke’s 230-kV Sampson Transmission Line in Cleveland County, North Carolina, Duke requests commission approval to construct a 1,123 foot fold-in line to connect the transmission line and a new switching station to the generating facility. DEC has acquired all necessary right-of-way easements for the fold-in line and switching station, and the property owner does not object to the line or switching station construction or to the waiver of notice and hearing requirements.

A Certificate of Environmental Compatibility and Public Convenience and Necessity (CPCN) is required for the line construction. But state law authorizes the utility to obtain a waiver of the notice and hearing requirements for such a CPCN if certain requirements are met. Duke said this project meets those conditions. A commission rule requires that this Duke Energy (NYSE: DUK) subsidiary prefile its application and motion with the Public Staff Electric Division at least 20 days prior to actually filing its application and motion with the commission, and to simultaneously file a notice of intent to seek a waiver with the commission. The Jan. 27 filing meets that need.

These transmission facilities would serve the new NTE Carolinas 450-MW, gas-fired Kings Mountain Energy Center project. The Duke Energy Carolinas service area includes Kings Mountain in North Carolina.

A Duke 230-kV Switching Station will be constructed immediately adjacent to the NTE generating plant. A fold-in (i.e., where the existing lines are folded into the breakers then back out, and the switching station is located immediately adjacent to the existing lines) of the existing 230 kV Sampson Transmission Line will be required to interconnect the new generation.

NTE Energy broke ground on the Kings Mountain Energy Center in July 2015 with Gemma Power Systems LLC building the facility under a fully-wrapped engineering, procurement and construction (EPC) services contract. NTE Energy says the $800 million facility will be one of the most efficient and clean sources of capacity and energy in the Carolinas employing Mitsubishi’s GAC turbine technology in a combined-cycle configuration. The plant is scheduled for commercial operation in 2018.
