NiSource announces long-term agreement with Microsoft expected to increase customer savings and support Indiana’s economic growth

NiSource signed a long-term energy agreement with Microsoft for its northwest Indiana data center campus — approximately 1,100 MW of new generation resources under a 20-year term beginning in 2028. Microsoft fully funds all generation and transmission required to serve its load, with the structure designed to shield existing NIPSCO electric customers from incremental costs. The deal lifts total expected NIPSCO customer savings from the previously disclosed $1.4 billion to approximately $1.75 billion — as much as $140 per customer annually.
