Microsoft will pay for its own power in Indiana, and NiSource rose 3.47%
NiSource rose 3.47% on Friday to US$42.68. The utility had just signed a 20-year deal to supply about 1,100 megawatts to a Microsoft data-centre campus in northwest Indiana, starting in 2028.
The interesting part is who pays. Microsoft will fund all the generation and transmission the campus needs. Its Jeff Riles said the company is "committed to paying our own way."
NiSource says its existing customers come out ahead. It now expects data-centre contracts to save customers of NIPSCO, its Indiana electricity business, about US$1.75 billion over their life, up from US$1.4 billion, or as much as US$140 a customer each year.
Microsoft joins two other tech giants. In April NiSource added Alphabet as a customer and expanded an existing deal with Amazon, and put the savings at about US$1.25 billion.
the detail behind the US$1.75 billion. NiSource has promised more on the deal with its September-quarter results. A data centre that pays for its own power station is easier for a town to welcome, and that matters as these campuses look for new sites.
