What NiSource does
NiSource Inc. (NYSE: NI) is one of the largest fully-regulated utility companies in the United States, headquartered in Merrillville, Indiana, and operating since 1912 with approximately 7,700 employees. Through its Columbia Gas and NIPSCO sub-brands, the company delivers regulated natural gas distribution to approximately 3.3 million customers and regulated electric distribution and generation to approximately 500,000 customers across six states — Indiana, Kentucky, Maryland, Ohio, Pennsylvania, and Virginia. The underlying infrastructure includes 41,000+ miles of pipeline surveyed, 545,000+ advanced smart meters with leak-detection capability, and a generation portfolio transitioning from coal toward renewables (target 0% coal-fired generation by 2028) supplemented by approved combined-cycle gas turbines and battery energy storage systems.
The company's revenue model is fundamentally that of a regulated utility: usage-based tariffs approved by state utility commissions (IURC, PUCO, PAPUC, KPSC, MDPSC, SCC), billed monthly to residential, commercial, and industrial customers. Three primary revenue streams are documented: natural gas distribution (the largest, across Columbia Gas territories), electric distribution and generation through NIPSCO, and a newer data center energy services stream executed through the NIPSCO Generation LLC (GenCo) subsidiary. GenCo ring-fences data center generation costs from the broader regulated balance sheet, enabling hyperscaler customers (Amazon, Alphabet) to fund their own generation and transmission infrastructure while delivering approximately $1.4 billion in projected customer savings over contract life.
NiSource's go-to-market relies on regulated franchise territories and direct utility service rather than traditional sales channels. Recent growth has been driven by direct negotiations with hyperscalers for large-load data center contracts requiring Indiana Utility Regulatory Commission approval. The company has executed a $28 billion 2026-2030 capital plan (with ~$7 billion earmarked for data center infrastructure), sold a 19.9% NIPSCO minority stake to Blackstone Infrastructure Partners for $2.15 billion, and established a $1.5 billion ATM equity program to fund the buildout. Adjusted EPS CAGR guidance has been raised to 9-10% through 2033, with FY2025 GAAP net income of $929.5 million (up 25.7% YoY) and 2026 adjusted EPS guidance of $2.02-$2.07.

NiSource competitors and assessment
Company assessmentDirect peers
- CenterPoint Energy: Houston-based regulated electric and natural gas utility. T. Rowe Price identified it alongside NiSource as a top utility for AI-driven power demand, making it a directly comparable peer benefiting from hyperscaler data center load growth in its Texas/Midwest service territory.
- Duke Energy: Largest US investor-owned utility serving the Carolinas, Florida, and the Midwest. Duke shares NiSource's regulated electric and gas distribution model, multi-state regulatory footprint, capital-intensive generation transition, and growing data center demand exposure in the Carolinas.
- PPL Corporation: Pennsylvania-based regulated utility with electricity delivery to Kentucky, Pennsylvania, and Rhode Island. T. Rowe Price specifically named it alongside NiSource as a top utility for AI-driven power demand, sharing the multi-state regulated distribution model and dividend growth profile.
- Entergy Corporation: New Orleans-based regulated electric utility serving Louisiana, Arkansas, Mississippi, Texas, and Tennessee. Entergy is a comparable Midwest/South utility with significant hyperscaler data center contracts in its service territory and a similar growth-by-data-center-load thesis.
- Dominion Energy: Virginia-headquartered regulated utility with the largest US data center customer base in Northern Virginia. Dominion is the most direct peer to NiSource's data center strategy given its hyperscaler concentration in Virginia, comparable generation build-out approach, and regulated rate base funding model.
- American Electric Power (AEP): Ohio-headquartered regulated electric utility with the largest US transmission network across 11 states. AEP is a comparable large multi-state regulated utility with overlapping Midwest/Mid-Atlantic service territory and growing data center load from hyperscalers.
- Ameren: Missouri-based regulated electric and gas utility serving Missouri and Illinois. T. Rowe Price flagged it together with NiSource as a top defensive utility stock for AI-driven power demand, with a comparable regulated rate base model and significant data center exposure in the Midwest.
Broad incumbents
- Constellation Energy: Largest US operator of nuclear power plants with significant hyperscaler data center deals (e.g., Microsoft Three Mile Island restart). Constellation is a directly comparable peer leveraging carbon-free generation capacity to serve AI data center demand, competing with NiSource for hyperscaler offtake.
- NextEra Energy: Florida-headquartered regulated utility and world's largest generator of wind and solar energy. NextEra is a comparable peer in renewable generation buildout to serve data center demand, with a much larger scale and broader geographic footprint than NiSource.
- Vistra Corp: Largest US competitive power generator with significant nuclear, gas, and coal capacity. Vistra is a comparable peer pursuing large-scale data center power supply contracts (including with hyperscalers) and represents the broader IPP model that competes with NiSource's GenCo subsidiary structure.
