- NiSource Inc. is an energy holding company primarily engaged in regulated natural gas and electric utility operations in the United States. The company’s core products and services include natural gas distribution and electric generation, transmission, and distribution. Operating under the Columbia Gas and Northern Indiana Public Service Company (NIPSCO) brands, NiSource serves nearly four million customers across six states, including Indiana, Ohio, Pennsylvania, Virginia, Kentucky, and Maryland. It provides safe and reliable natural gas for residential, commercial, and industrial use, alongside electric power generation utilizing a mix of traditional and renewable energy sources such as natural gas, hydroelectric, wind, and coal. The company also offers wholesale and electric transmission services, managing an electric system with a net capability exceeding 3,000 megawatts. Founded in 1912 and headquartered in Merrillville, Indiana, NiSource has approximately 7,700 employees.
NiSource’s recent major changes include a strategic minority equity partnership with Blackstone Infrastructure Partners, which acquired a 19.9% indirect equity interest in NIPSCO for $2.15 billion, along with an additional $250 million equity commitment to fund ongoing capital needs. This partnership strengthens NIPSCO's financial foundation and supports long-term sustainable growth, especially in renewable energy projects and infrastructure modernization. NiSource continues to implement a comprehensive infrastructure modernization program, replacing aging natural gas pipelines and upgrading electric systems while focusing on environmental upgrades and resilience enhancements. The company's investments are part of a broader strategy targeting approximately $20 billion in infrastructure spending over the next five years, emphasizing safety, emission reductions, and updated customer services. NiSource also pursues initiatives aimed at reducing carbon emissions by over 90% by 2028, accelerating the transition to greener energy solutions.
NiSource operates mainly in the regulated utilities sector, targeting residential, commercial, and industrial customers. Its subsidiaries provide full service electric and gas utilities with a focus on modernizing energy infrastructure and adopting renewable energy sources. The company’s electric operations primarily serve northern Indiana, and its gas operations span six states in the U.S. Midwest and Mid-Atlantic regions. NiSource’s business segments include the Columbia Operations and NIPSCO Operations, each dedicated to regulated gas and electric utility services. The partnership with Blackstone Infrastructure Partners extends to GenCo, an affiliate designed to manage generation assets serving growing energy demands in the data center industry in Northern Indiana. NiSource’s strategic alliances and investments reinforce its commitment to safe, reliable, and sustainable energy delivery, aligning with industry trends and regulatory requirements to maintain stable revenue streams and support shareholder value growth.
