WARREN — Enbridge, an energy company headquartered in Calgary, Canada, announced Thursday it has completed its acquisition of locally operating East Ohio Gas from Dominion Energy.

The gas utility will be doing business as Enbridge Gas Ohio and will join Enbridge’s gas distribution and storage business unit. The deal is worth about $6.6 billion.

Enbridge, in a bews release, called East Ohio Gas “a premier single-state utility.” It services more than 1.2 million customers across more than 400 communities, including Trumbull, Mahoning and Columbiana counties.

The utility has more than 22,000 miles of transmission, gathering and distribution pipelines, underground storage, and interconnections to multiple interstate pipelines and large natural gas producers.

“The addition of a strong Ohio-based gas utility company is a great strategic fit for Enbridge. It further diversifies our business and enhances the stable cash flow profile of our assets,” Michele Harradence, Enbridge executive vice president and president, gas distribution and storage, said.

Enbridge in September announced it acquired three U.S. energy companies in deals worth about $14 billion.

The others are Questar Gas, which serves about 1.2 million customers across Utah, and the Public Service Company of North Carolina, also known as PSNC Energy, which serves more than 600,000 customers across 28 counties in North Carolina.

Enbridge reported then with the acquisitions, its gas utility business would be the largest by volume in North America.

The acquisitions of Questar and PSNC are on track to close in 2024, according to Enbridge.
