The story of NiSource began in 1932 as the Northern Indiana Public Service Company (NIPSCO). However, its origins can be traced back to 1912 through mergers that formed the Columbia Gas and Electric Corporation. Understanding the early ownership of NiSource involves looking at its evolution from these foundational entities.

While the exact details of the founding team are not widely publicized in readily available sources, the formation of NIPSCO was a result of consolidating utility companies in Northern Indiana. This consolidation aimed to improve efficiency and service delivery in the region. Information on the initial capital or funding at the company's inception is not available in public disclosures.

The Public Utility Holding Company Act of 1935 played a significant role in shaping the company's structure. This act led to the reorganization of Columbia Gas and Electric Corporation's subsidiaries. Consequently, the electric utilities were spun off, becoming the Columbia Gas System. NiSource Inc. itself was later organized in 1987 as NIPSCO Industries, Inc., before changing its name to NiSource Inc. on April 14, 1999. This restructuring, driven by regulatory mandates, significantly influenced the early ownership by separating gas and electric operations.

Early Ownership and Key Developments

The early ownership of NiSource was primarily influenced by the consolidation of utility companies and regulatory changes. The company's evolution from NIPSCO to NiSource Inc. reflects strategic shifts. These shifts were influenced by the Public Utility Holding Company Act of 1935.

• The initial formation was driven by the consolidation of several utility companies in Northern Indiana.
