NiSource Inc. NI

NI Company Overview

NiSource Inc. is a U.S.-based, fully regulated energy holding company that operates natural gas distribution and electric utility businesses. The company primarily serves residential, commercial, and industrial customers and operates within the regulated utilities industry, with revenue largely derived from rate-based operations approved by state regulatory commissions. Its core activities focus on the delivery of natural gas and electricity, infrastructure modernization, and long-term system reliability.

The company’s principal businesses are conducted through its regulated utility subsidiaries, most notably Northern Indiana Public Service Company (NIPSCO) for electric and gas services and multiple Columbia Gas distribution utilities for natural gas. NiSource’s strategic positioning centers on predictable cash flows from regulated assets, a long-term capital investment framework, and a transition toward cleaner energy sources. Founded in 1912, NiSource evolved from a regional gas utility into a diversified regulated utility holding company, and over the past decade has simplified its portfolio by divesting non-core and unregulated assets to focus exclusively on regulated operations.
