Nisource Inc.
A utility holding company based in Merrillville, Indiana, NiSource delivers natural gas and electricity to millions of customers across six states under the Columbia Gas and NIPSCO brands. Its roots trace to 1912, when Gary-area businessmen formed the Northern Indiana Public Service Company to power the Gary Railway Company. The name "NiSource" comes from "Northern Indiana," adopted in 1999 after the company grew beyond its home state.
