B-System Project

Natural Gas Icon


The B-System Project is part of our ongoing investment in energy infrastructure in central Ohio.  This proposed modernization project will see the construction of approximately seven miles (11 km) of new natural gas pipeline, the replacement of 13.8 miles (22.2 km) of existing pipeline and the retirement of a 17.6 mile (28.3 km) pipeline.

This important project is part of a wider modernization program that replaces existing infrastructure and upgrades natural gas compression systems to improve the safety and reliability of our pipelines.

Frequently asked questions

The B-System project is part of an ongoing modernization program to replace existing infrastructure, upgrade natural gas compression systems and increase pipeline reliability.

The B-System has been slated for modernization because it is a vital natural gas supply line for the Columbus metro area, as well as for several towns and cities along the developing US Route 33 corridor southeast of Columbus.

It comes down to doing what’s best for the environment. After an environmental impact study and looking at the effects on landowners and overall costs, we determined that building a new, seven-mile (11 km) pipeline, rather than replacing the existing one, would result in lessened impact and lowered costs. The existing pipeline will be brought to the end of its lifecycle.

Absolutely. Landowners who may be impacted by our proposed route will be contacted early on in the process by a land representative. You’ll also be notified in advance if we need to make a survey of your property.
