Google to Curb AI Data Centre Power Use Amid U.S. Grid Surges

• Google partners with utilities to reduce AI data center power during peak grid demand.
• Agreements help manage grid strain, lower blackout risks, and support AI expansion.
• Demand-response programs may become more common as the U.S. electricity supply faces constraints.

Google has now signed breakthrough contracts with two American power companies, Indiana Michigan Power and Tennessee Power Authority, to cut energy use at its AI data centres at times of peak grid load.

As the rapid expansion of artificial intelligence outpaces available power supplies, these deals mark a significant step in managing electricity usage for Big Tech’s energy-intensive operations.

The surge in AI-driven data center demand has strained U.S. power grids, with requests for electricity exceeding available supplies in some regions. This has raised concerns about rising energy costs for households and businesses, as well as the potential for blackouts.

These demand-response programs, typically used by energy-heavy industries such as manufacturing or cryptocurrency mining, are a novel application for AI workloads. Google’s participation is the first formal instance of the company curtailing its machine learning operations to support grid stability.

According to a Google blog post, the arrangements allow data centers to connect to the grid more quickly, reduce the need for new power infrastructure, and enhance grid efficiency. While details of the commercial terms between Google and the utilities remain undisclosed, such programs often involve financial incentives like payments or reduced energy bills.

Although these agreements address only a fraction of grid demand, they could set a precedent as U.S. electricity supplies tighten, potentially encouraging broader adoption among tech giants.
