Duke Energy Begins Replacing Aging Gas Pipeline

By P&GJ Staff

Construction got underway this week on the 12-mile Central Corridor replacement pipeline designed to run though Hamilton County, Ohio, which is in the southeast corner of the state and contains the city of Cincinnati.

Duke said the aging infrastructure needs to be replaced as part of an effort to reduce reliance on gas from stations to the south and allow the company to go forward with retirement of peaking plants used during winter.

The company said it has critical propane peaking facilities that help provide natural gas to its regional customers during the coldest days, but  those plants must be retired.

“The Central Corridor Pipeline will enable us to upgrade existing infrastructure without interrupting natural gas service to our customers,” a Duke statement red. “Some of our existing pipelines have been in service for over 50 years.”

Duke said the facilities were placed in service in the early 1960s and “reflect outdated technology.” The facilities include a man-made cavern, located 400 feet underground for propane storage and that the cavern walls cannot be repaired.

“Duke Energy needs the flexibility to bring natural gas into Hamilton County from a diverse supply of pipelines located north of our Ohio service territory. Due to the way our system is configured, we cannot bring additional supplies of natural gas from the south,” Duke said.
