East Tennessee Natural Gas System Alignment Program

Enbridge, North America’s largest energy infrastructure company, is planning to modify portions of its existing East Tennessee Natural Gas (ETNG) pipeline system, which has supplied natural gas to customers for more than 70 years.

The proposed changes will improve the company's ability to meet shifting customer needs while continuing to provide affordable and reliable energy.

The East Tennessee Natural Gas System Alignment Program (ETNG SA Program) will consist of four projects across three states:

Tennessee

• Approximately 16.5 miles of new 24-inch-diameter pipeline next to an existing 16-inch-diameter pipeline within ETNG’s existing pipeline right-of-way as much as possible in Knox and Sevier Counties
• A new electrically driven natural gas compressor station on open land along ETNG’s existing pipeline right-of-way in Jefferson County

Virginia

• Replacement of 6.5 miles of existing 8-inch pipe with new 24-inch pipe within ETNG’s existing pipeline right-of-way in Washington County

North Carolina

• A new electrically driven natural gas compressor station on open land along ETNG’s existing pipeline right-of-way in Rockingham County

Work on the ETNG SA Program will be located along the existing pipeline system’s right-of-way where possible to minimize impacts to landowners and the environment.

Purpose

ETNG is a major transporter of natural gas to regional utility companies and electrical generation facilities that provide energy to consumers. Over time the system has experienced changes 

in regional use that pose challenges in meeting customer needs.  The proposed system changes would help ETNG to better meet those needs and fulfill its mission of providing affordable and  reliable energy.

Benefits

As the region continues to grow and change, these modifications would benefit all customers and allow ETNG to continue serving its customers as it has for more than seventy years.
