About Nisource Inc.

NiSource is the main energy source for resourceful Americans living in the Midwest, the South, and New England. The company's utility subsidiaries distribute natural gas to about 3.4 million customers in seven states. NiSource also generates, transmits, and distributes power to some 460,000 customers in 20 counties in its home state through its largest subsidiary, Northern Indiana Public Service Company (NIPSCO). NiSource owns one of the largest natural gas transmission and underground storage systems in the US, including a more than 15,000-mile interstate pipeline system.

Geographic Reach

Through subsidiary Columbia Energy, NiSource owns and operates five distribution subsidiaries that provide natural gas to 2.2 million residential, commercial and industrial customers in Ohio, Pennsylvania, Virginia, Kentucky, and Maryland. NiSource also distributes natural gas in Indiana through NIPSCO. Columbia Gas of Massachusetts distributes natural gas to  end users in Massachusetts. The company’s Columbia Transmission’s operations are located in Delaware, Kentucky, Maryland, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Virginia, and West Virginia, and Columbia Gulf’s operations are located in Kentucky, Louisiana, Mississippi, Tennessee, Texas and Wyoming. Several of NiSource's utilities participate in customer choice programs in states with deregulated energy markets. CNS Microwave operates 75 microwave towers in Kentucky, Louisiana, Maryland, Mississippi, Ohio, Pennsylvania, Tennessee, Virginia, and West Virginia.


The energy holding company operates in three major business areas: gas distribution; gas transmission and storage; and electric generation, transmission, and distribution. It also provides retail services, as well as telecommunications infrastructure for wireless applications.

Sales and Marketing

The company's utility subsidiaries distribute natural gas to about 3.4 million customers in seven states via 58,000 miles of pipeline.

Financial Performance

NiSource's revenues have been restated due to divestiture of the natural gas marketing and retail services businesses. In 2013 the company’s revenues grew by 12% due to a rise in gas distribution revenues as a result of an increase in regulatory and service programs. Other factors included the impact of colder weather (which spiked residential, commercial, and industrial usage) and an increase in residential and commercial customers. The company also experienced an increase in the gas transportation and storage revenues in 2013.

The company’s net income increased by 28% in 2013 to $532.1 million (from $416.1 million in 2012) primarily due to higher revenues and a gain from discontinued operations.

In 2013 NiSource's operating cash inflow increased to $1.4 billion (from $1.3 billion in 2012) due to an increase in working capital from income tax receivables of $255.9 million, primarily due to a refund from the IRS.


NiSource believes that its long-term success lies in developing a portfolio that balances creating more efficiencies in its regulated utility operations while expanding its higher-growth gas transmission and storage businesses.

In 2014 NiSource announced plans to spin off its pipelines into a separately traded public company. The new company, Columbia Pipeline Group, will include 15,000 miles of natural gas pipeline and 300 billion cu. ft. of storage, plus other midstream assets in the Marcellus and Utica shales.

In recent years NiSource has sold non-core businesses. In 2013 Lake Erie Land, a wholly-owned subsidiary of NiSource, waspursuing the sale of the real estate assets it owns. NDC Douglas Properties, a subsidiary of NiSource Development Company, was in the process of exiting its low income housing investments. In addition, to raise cash, the company sold certain retail services business assets (warranty protection solutions and energy efficiency leasing solutions for residential and small business utility customers) to AGL Resources in 2013. The deal includes 500,000 existing customer plans in Indiana, Massachusetts, Ohio, Pennsylvania, and Kentucky. The company exited these business lines in 2013. It also sold the commercial and industrial natural gas portfolio of its unregulated natural gas marketing business that year.
