NiSource Inc. (NI) has secured a 20-year energy agreement with Microsoft to supply power for its northwest Indiana campus. Under the terms of the arrangement, Microsoft will fully fund all necessary power generation and transmission infrastructure required to serve the facility.

The long-term contract boosts total expected savings for NIPSCO electric customers to approximately $1.75 billion over the duration of data center commitments, up from a previous estimate of $1.4 billion. The deal expands the power generation pool by roughly 1,100 megawatts and incorporates 600 megawatts of battery storage. Because Microsoft is paying for the required infrastructure, the agreement reduces financial risk for current utility ratepayers.

Energy deliveries under the deal are anticipated to begin in 2028. Moving forward, key factors to track include regulatory approvals, construction progress, project financing, and potential earnings impacts discussed on upcoming financial calls.
