Duke Energy Modifies Plan for Central Corridor Pipeline Extension Project

Posted on


In response to community feedback, Duke Energy has modified its plan for the Central Corridor Pipeline Extension Project. The company is now proposing to the Ohio Power Siting Board (OPSB) to construct a smaller natural gas pipeline that operates with less pressure.

The proposed pipeline would have a 20-inch diameter and operate at approximately 400 pounds per square inch (psi), compared with the original design, which called for a 30-inch pipe with an operating pressure of approximately 600 psi. 

This newly proposed pipeline will still enable Duke Energy to retire aging propane peaking plants. It will also moderately decrease reliance on natural gas from a single source in the southern part of the company’s system that has reached its maximum capacity. 

Longer-term system needs will be addressed through other modernization programs to be implemented over the next decade.

"We have been listening to feedback from our customers, neighbors and community leaders," said Jim Henning, president of Duke Energy Ohio and Kentucky. "The reduction in size and pressure of the proposed natural gas pipeline is a direct result of this feedback." 

"This new pipeline is critical for us to continue safely meeting the natural gas needs of nearly two million people in this region, both today and for generations to come," he added. 

As part of today’s filing with the OPSB, the company submitted two proposed pipeline routes for consideration. The preferred route identified in the application will be the eastern route and would terminate in Fairfax. The company was also required to submit an alternate route. Both routes are shown at this link. The OPSB will decide the final route and may also suggest modifications as well.
