Company overview
Northern Indiana Public Service Co. operates as a regulated electric and natural gas utility serving northeastern Indiana and southwestern Michigan, delivering generation, transmission, and distribution service to municipalities and commercial, industrial, and residential customers across a largely manufacturing-driven SIC 4910 energy landscape; its core offerings include reliable electricity production, natural gas supply, and ancillary services like demand management and storm restoration support tailored to schools, hospitals, and industrial plants that depend on steady power for sensitive operations. The company’s governance overlaps with state and federal regulators that oversee rate cases, emission controls, and infrastructure investments, exposing it to material risks such as shifting environmental mandates, capital-intensive grid upgrades, and weather-related outages that could trigger costly repairs or revenue volatility. With ongoing attention to compliance and modernization, Northern Indiana Public Service Co. invites stakeholders to view live SEC filings on Earnings Feed.
