History

More than a century of progress for our customers

America’s progress was made possible by the strength of the nation’s energy infrastructure, hard work, innovation and perseverance. We've been a part of this progress for more than a century.

Our predecessor companies date back as far as 1847, but one recent historical moment was the separation of NiSource and Columbia Pipeline Group. This allowed NiSource to operate as a stand-alone utility company. By focusing on strategically investing in our energy infrastructure annually, we'll be able to meet our customer commitments for the next 100 years.
