Data center upside, utility-sized strain
- NiSource is still a regulated utility first, with most profit tied to state-approved rates.
- The upside now sits in NIPSCO GenCo, which has data center deals with Amazon and Alphabet.
- Existing data center projects now need $9.25 billion to $9.75 billion of assets, a much larger build than earlier expectations.
- Amazon's ADS commitment rises to 2,800 MW by the end of 2032, while Alphabet adds 300 MW by 2030.
- The stock has a clear growth story, but valuation and balance sheet risk keep Finn's overall view cautious.
Big load, bigger test
NiSource has changed from a steady utility story into a utility with a large data center buildout attached. The core business still earns money the normal utility way: it invests in pipes, wires, power plants, and grid upgrades, then asks regulators to let it recover those costs plus a fair return.
The bull case is that NIPSCO GenCo turns Northern Indiana power demand into a long growth runway. Amazon's ADS contract is moving toward 2,800 MW by the end of 2032, Alphabet adds 300 MW by 2030, and management has pointed to about 3 GW in strategic negotiations. If these projects work, NiSource can push toward its 9% to 10% adjusted EPS CAGR goal and pass large savings back to existing retail customers.
The bear case is scale. The assets needed for current data center customers are now estimated at $9.25 billion to $9.75 billion. That is a lot for a regulated utility to finance and build while also keeping credit metrics healthy, winning IURC approvals, and handling MISO grid limits.
This is why the story is attractive but not clean. Growth has improved, yet the price already asks investors to believe in years of smooth execution. Finn's weaker valuation and financial health scores line up with that concern.
Rates pay the base, contracts fuel growth
NiSource makes most of its money from regulated gas and electric utilities. In simple terms, it spends money on safe and reliable energy systems, then regulators decide how much customers should pay so the company can earn a set return.
Columbia Operations is the gas utility group outside Indiana. It serves gas customers in Ohio, Pennsylvania, Virginia, Kentucky, and Maryland. Growth here comes from replacing older pipes, adding safety systems, and getting those investments included in rates.
NIPSCO Operations serves Northern Indiana with gas and electric service. This is where the data center plan lives. GenCo supports large-load customers through special contracts that include capacity payments, which are payments for having power available, not only for power used.
The model can break if costs rise faster than regulators or customers allow. It can also break if NiSource needs too much debt or equity to fund GenCo, or if MISO power market rules cut the value of the resources GenCo plans to use.
What NiSource sells
Columbia Gas distribution
This is the multi-state gas utility group. It is slower growth, but it provides a steady base through regulated pipe replacement and safety spending.
NIPSCO electric utility
NIPSCO supplies electricity in Northern Indiana. It is the center of the data center strategy and the company's coal-to-gas, renewable, and storage transition.
NIPSCO gas utility
This business distributes natural gas in Northern Indiana. It grows through customer additions, system upgrades, and approved rate recovery.
NIPSCO GenCo
GenCo is the new large-load platform serving data centers. It has contracts tied to Amazon and Alphabet, but the required asset build is very large.
Renewables and battery storage
NiSource is adding wind, solar, and batteries as it moves away from coal. Battery projects also support data center service under the pooled resource model.
Large industrial and data center infrastructure
NiSource can provide power and gas infrastructure to large customers. The opportunity is meaningful, but new deals would likely require more generation assets and more financing.
Two reportable pieces
Mix is based on Q1 2026 reportable-segment operating revenue before Corporate and Other. NIPSCO is smaller by current revenue, but it holds the main data center upside and the largest execution risk.
What could go wrong
GenCo build costs outrun the plan
High impact · Medium oddsNiSource now expects $9.25 billion to $9.75 billion of assets for existing data center customers. That includes large gas generation, batteries, and other pooled resources. Cost overruns or delays could lower returns and force more financing.
Balance sheet pressure
High impact · Medium oddsManagement ended 2025 with FFO to debt above its 14% to 16% target range, but the GenCo plan is close to $10 billion for current contracts alone. More debt or equity could weaken per-share growth. The company had $1.25 billion of ATM equity capacity available as of March 31, 2026.
Regulators say no, or say yes too slowly
High impact · Medium oddsThe Alphabet contract and Amazon ADS amendments need IURC and FERC approvals. These contracts are meant to protect existing customers and pass savings back to them, but regulators still need to accept the structure. A delay could slow the buildout and weaken the growth case.
MISO reliability problems keep coal alive
Medium impact · High oddsNIPSCO planned to retire the R.M. Schahfer coal facility, but DOE emergency orders have required it to stay available because of MISO power shortfalls. A later DOE order extended the requirement into September 2026. This can raise costs and complicate NiSource's energy transition plan.
Data center pipeline slows
Medium impact · Medium oddsThe current bull case assumes NiSource can turn more of its roughly 3 GW strategic negotiation pipeline into signed contracts. If customers delay projects, choose other sites, or push for lower returns, GenCo may look less valuable. The fixed utility base would still exist, but upside would shrink.
In one breath
What does NiSource do?
NiSource owns regulated gas and electric utilities. Its main brands are Columbia Gas across several states and NIPSCO in Northern Indiana.
Why do investors care about NiSource data centers?
Data centers need huge amounts of power. NiSource's NIPSCO GenCo has contracts with Amazon and Alphabet, which could drive faster earnings growth than a normal utility plan.

The biggest risk is execution on the GenCo buildout. The company must finance and build $9.25 billion to $9.75 billion of assets for existing data center contracts while keeping regulators and credit agencies comfortable.
Is NiSource only an electric utility?
No. It has both gas and electric operations. Columbia Operations is gas distribution, while NIPSCO includes both gas and electric service in Northern Indiana.
