This establishment marked the beginning of a long-standing utility presence in the Midwest United States, initially focusing on natural gas and electric service in Indiana. The company remained a key regional player for decades, evolving through various corporate structures while maintaining its core regulatory utility status.
Mid-20th Century Reorganization
In 1935, the company underwent a significant reorganization that helped solidify its market position and operational framework. This period of structural adjustment was critical for the utility's growth, allowing it to expand its infrastructure and customer base throughout Indiana. By the late 20th century, the entity had become the sole Indiana-based utility company, a distinction it held as of 2018. The company is headquartered in Merrillville, Indiana, and employs more than 8,000 workers, reflecting its substantial operational scale within the state.
Merger and Expansion
A major turning point in the company's history occurred in 2000 with the merger with Columbia Energy Group.

Following the merger, the combined company, now operating under the NiSource name, served approximately 3.5 million natural gas customers and 500,000 electric customers across six states. The merger integrated the Columbia Gas and NIPSCO brands, allowing for a more diversified regional presence beyond Indiana.
Recent Corporate Restructuring
In 2015, NiSource executed a significant corporate spin-off, separating the Columbia Pipeline Group. This move allowed the parent company to focus more intently on its regulated utility operations while enabling the pipeline assets to operate as a distinct entity. The spin-off reflected a broader trend in the energy sector to separate regulated utility businesses from midstream pipeline operations. Today, NiSource Inc. continues to operate as one of the largest fully regulated utility companies in the United States, maintaining its operational status and serving its customer base through its established local brands.

Coal Retirement and Energy Transition
In 2019, NiSource announced a strategic initiative to retire its coal-fired generating units. This decision marked a pivotal moment in the company's generation mix, reflecting broader trends in the U.S. energy sector toward lower-carbon sources. The retirement plan aimed to reduce greenhouse gas emissions and improve air quality in the regions served by NIPSCO and Columbia Gas. Coal units had historically provided baseload power, but increasing competition from natural gas and renewable energy sources, along with regulatory pressures, made coal less economically viable. The company committed to a phased approach to ensure grid reliability during the transition. This move aligned with investor expectations for environmental, social, and governance (ESG) performance and responded to stakeholder demands for cleaner energy options. The retirement of coal assets also opened opportunities for NiSource to invest in natural gas infrastructure and renewable energy projects, leveraging its expertise in gas distribution to integrate new power sources.
Your Energy, Your Future Initiative
NiSource launched the "Your Energy, Your Future" initiative to guide its long-term sustainability goals. This comprehensive strategy aims to achieve a 90 percent reduction in carbon emissions by 2028.

Why did NiSource face criticism over tax and lobbying?
In 2011, NiSource Inc. faced significant public scrutiny regarding its financial expenditures and executive compensation structures. The criticism was primarily driven by an analysis conducted by Public Campaign, a non-partisan research and advocacy organization focused on money in politics. This analysis highlighted a disparity between the utility company's lobbying efforts, tax benefits, and the resulting financial gains for its top executives.
Lobbying and Tax Expenditures
According to the 2011 analysis, NiSource spent approximately $1.83 million on lobbying activities. These expenditures were aimed at influencing legislation and regulatory decisions across the six states where the company operates, including Indiana, Ohio, Pennsylvania, New Jersey, Maryland, and Delaware. The lobbying efforts were seen as a strategic investment to secure favorable regulatory environments for its natural gas and electric customer bases.
Concurrently, the analysis pointed to substantial tax rebates received by the company. NiSource benefited from approximately $227 million in tax rebates during the period under review. These tax advantages were part of the broader financial landscape for regulated utility companies, which often leverage state and federal tax codes to manage operational costs and capital expenditures. The combination of high lobbying costs and significant tax relief drew attention to the company's overall financial efficiency and its impact on shareholders and ratepayers.
Executive Compensation
A central point of contention was the increase in executive pay at NiSource. The analysis suggested that despite the company's lobbying and tax strategies, the financial benefits accrued significantly to the top leadership. Critics argued that the rise in executive compensation was disproportionate to the performance metrics or the financial burden placed on customers through rate adjustments. This perception fueled public debate about corporate governance and the alignment of executive incentives with shareholder and consumer interests.
NiSource's Response
In response to the criticism, NiSource Inc. defended its financial strategies and compensation packages. The company emphasized the complexity of the regulated utility sector, where executive compensation is often tied to long-term infrastructure investments, service reliability, and regulatory approvals. NiSource argued that the lobbying expenditures were necessary to navigate the diverse regulatory environments across its operational states, ensuring stable service for its approximately 3.5 million natural gas customers and 500,000 electric customers.
The company also highlighted its role as a major employer, with more than 8,000 employees based in Merrillville, Indiana. NiSource maintained that its tax strategies were consistent with industry standards and were designed to optimize capital for future growth and maintenance of its energy infrastructure. By framing its financial decisions within the context of operational necessity and shareholder value, NiSource sought to mitigate the negative public perception generated by the 2011 analysis.
Why it matters
NiSource Inc. holds a distinct position in the United States energy sector as the sole Indiana-based utility company, a status it maintained as of 2018. This unique regional anchor underpins its broader significance as one of the largest fully regulated utility companies in the country.
