Google agrees to curb power use for AI data centres

Google has signed agreements with two US electric utilities to reduce its AI data centre power consumption during times of surging demand on the grid when energy-intensive AI use outpaces power supplies.

Utilities in the country have been inundated with requests for electricity for Big Tech's AI data centres, with demand eclipsing total available power supplies in some areas.

That power crunch has led to concerns about spiking bills for everyday homes and businesses, as well as power blackouts.

It has also complicated the technology industry's expansion of AI, which requires massive amounts of electricity quickly.

Google's agreements with Indiana Michigan Power and Tennessee Power Authority would involve scaling back power use at the technology giant's data centres when called upon by the electric utilities to free up space on the grid.

They are the first formal agreements by Google in demand-response programs with utilities to temporarily curtail its machine learning workloads, a subset of artificial intelligence.

"It allows large electricity loads like data centres to be interconnected more quickly, helps reduce the need to build new transmission and power plants, and helps grid operators more effectively and efficiently manage power grids," Google said in a blog post. 

Demand-response programs have typically been used by other energy-intensive industries, such as heavy manufacturing or cryptocurrency mining. In exchange, the businesses generally receive payments or reduced power bills.

The programs involving AI activity in data centres are generally new, and details of the commercial arrangements between Google and the utilities were not clear.

While demand-response agreements apply only to a small portion of demand on the grid, the arrangements may become more common as the US electricity supply tightens.
