With IURC approval, the structure unlocks energy solutions tailored for the data center boom while protecting existing customers, enabling growth and securing long-term value.

NiSource Inc. (NYSE: NI) has received Indiana Utility Regulatory Commission’s (IURC) approval for its NIPSCO Generation LLC (GenCo) declination petition. GenCo is designed to own, build and manage generation assets to serve the growing data center industry in Northern Indiana.

This approval marks a pivotal moment for our company and the region, unlocking GenCo’s ability to protect existing NIPSCO retail customers and best serve data center and other large load customers. GenCo’s strategic pillars include:

• Customers First: GenCo was created to shield NIPSCO’s existing retail customers from costs associated with serving new data center customers.
• Growth Ready: By operating as a separate entity, GenCo is best positioned to meet the demands of new data center customers quickly and flexibly.
• Financial Stability: GenCo enables NiSource to make prudent investments, manage costs effectively and create predictable cash flows.
• Future Flexibility: GenCo allows for quick adaptability as energy markets evolve, ensuring that the company can pursue future opportunities on behalf of the region without compromising customer value.

“This is an important step forward to position Northern Indiana at the center of a fast-growing, economically essential industry,” said NiSource President and CEO, Lloyd Yates. “The order reflects confidence in our ability to deliver safe, reliable and affordable energy solutions for our communities. It gives us the tools we need to grow responsibly while ensuring that every decision we make keeps customers front and center.”

IURC’s decision enables GenCo’s to execute on its growth-focused strategy. With this order, NIPSCO is well positioned to power Indiana’s economic growth while protecting the communities it serves – today and tomorrow.
