NiSource secures 20 — year power supply agreement with Microsoft

NiSource entered a 20-year energy agreement with Microsoft for its northwest Indiana campus, with service expected to start in 2028. GenCo's generation portfolio will expand by approximately 1,100 MW; Microsoft will fully fund generation and transmission required to serve its load. The agreement increases expected NIPSCO electric customer savings over data center contracts' lifetimes to approximately $1.75 billion from $1.4 billion. Expected savings equate to as much as $140 per customer annually, with existing customers protected from costs of serving the data center. GenCo also contracted 600 MW of battery storage under a long-term tolling agreement for its portfolio serving multiple large-load customers.
