American utility company NiSource has signed major long-term contracts to power the energy-hungry data centers of Alphabet (Google) and Amazon. This deal is a significant development in how energy companies are responding to the massive electricity demand driven by the artificial intelligence (AI) boom.
The backdrop to this story is the explosive growth of AI, which requires vast data centers that consume enormous amounts of electricity. Tech giants, often called 'hyperscalers', are in a race to secure reliable, long-term power sources. This has put immense pressure on utility companies to rapidly expand their generation capacity. NiSource's agreement is a direct response to this trend, but it was made possible through a series of strategic moves.
So, how did NiSource pull this off without raising electricity bills for its regular customers? The answer lies in a clever, multi-step strategy.
First, they established the right regulatory framework. In September 2025, Indiana regulators approved NiSource's creation of a separate subsidiary called a 'GenCo' (Generation Company). This special entity is designed to serve large industrial customers like data centers exclusively. By isolating these massive projects within the GenCo, the investment costs don't get passed on to residential customers through their 'rate base', protecting them from price hikes.
Second, NiSource secured the necessary funding for these huge projects. In early 2024, the company sold a minority stake in its subsidiary to the investment firm Blackstone, raising over $2 billion. This provided the financial firepower needed to build new power plants and infrastructure to meet the demand from companies like Amazon and Alphabet.
Third, they landed an anchor client that proved the model worked. In late 2025, NiSource signed a massive deal with Amazon, which served as a blueprint. This successful precedent gave Alphabet the confidence to sign a similar agreement, knowing that NiSource had the experience, capital, and regulatory approval to deliver.
Ultimately, this innovative approach creates a win-win-win situation. Big Tech gets the stable power it needs, NiSource secures profitable long-term customers, and existing residents not only avoid rate increases but will actually see their bills go down by an estimated $90–$115 per year. This deal serves as a pioneering model for how utilities can transform the challenge of the AI energy surge into a major opportunity for growth and community benefit.
