History
NiSource was founded in 1912 as the Northern Indiana Public Service Company, which merged with several other companies to become the Columbia Gas and Electric Corporation. Under the Public Utility Holding Company Act of 1935, Columbia was forced to reorganize its subsidiaries and eventually spun off its electric utilities, becoming the Columbia Gas System. In 2000, NiSource merged with Columbia Energy Group, but in 2015, NiSource was spun off from Columbia Pipeline Group.[2][3] The next year, Columbia Pipeline Group was acquired by TransCanada Corporation, while the Columbia Gas distribution companies remained with NiSource.
Company operations
NiSource's natural gas utilities provide domestically produced supplies of natural gas to residential, commercial and industrial customers via nearly 60,000 miles of pipeline and related facilities in six states: Indiana, Kentucky, Maryland, Ohio, Pennsylvania and Virginia.
