NiSource Signs Power Deal with Alphabet, Expands Amazon Agreement
U.S. utility company NiSource announced on April 16, 2026, that it has signed a long-term energy supply agreement with a unit of Alphabet to support a large data center in northern Indiana. Additionally, NiSource expanded its existing partnership with Amazon to accelerate power delivery to its facilities and bring forward bill credits for residential customers. These agreements utilize NiSource's GenCo model, which supplies power to large industrial clients through dedicated generation and market resources while shielding existing households from additional costs. The company estimates that this model will generate approximately $1.25 billion in system-wide savings, translating to $90 to $115 annually per household. The power supply for Alphabet is scheduled to commence in summer 2026, involving about 340 megawatts from GenCo-owned portfolio assets supplemented by up to 175 megawatts of seasonal market purchases. This development highlights the growing trend of Big Tech firms securing reliable, cleaner energy sources to fuel their rapidly expanding data centers driven by artificial intelligence applications, even as other regions like Maine face legislative pushback against such infrastructure due to grid strain concerns.
