Duke Energy Progress told the North Carolina Utilities Commission in a July 28 update that the 84-MW blackstart turbine project at its Sutton power plant is running below budget on cost and is due for commercial operation in June 2017.
The commission in August 2015 Issued a Certificate of Public Convenience and Necessity for the project. Duke Energy Progress is a unit of Duke Energy (NYSE: DUK).
Duke noted that the original cost estimate for the project was $132.1 million, which is now down to $119 million. AFUDC is not included. The project began construction on April 4 of this year, and is due for first fire in May 2017 and for commercial operation in June 2017.
The project includes two new nominal 42-MW simple-cycle combustion turbine (CT) dual-fuel units installed at the existing L.V. Sutton Energy Complex, located in New Hanover County near Wilmington, North Carolina. The Sutton Blackstart CT Project will provide three important functions in the unlikely event of a system blackout, namely, to restore the transmission system, to provide offsite power to the Brunswick Nuclear Plant, and to comply with related North American Electric Reliability Corp. (NERC) Reliability Standards. The Sutton Blackstart CT Project will also provide fast-start capability that the existing units do not have, thereby providing additional resources for Duke Energy Progress to meet NERC contingency reserve requirements.
