Google leans on demand response to keep AI data centers running at peak hours

The company has lined up 1 GW of flexible capacity with five US utilities and is scaling a virtual power plant deal with Voltus tenfold Google wants its AI data centers to know when to take a breather. The company is exploring demand-response programs to cover the power needs of its AI data centers during peak hours. Under these arrangements, Google’s facilities can dial down or reschedule work when the grid gets stretched thin. AI workloads are driving electricity demand sharply higher. Utilities are being asked to connect very large new loads faster than they can build the generation and transmission to serve them. Demand response offers a way to squeeze more use out of the grid that already exists. What Google has actually signed For Google, that means shifting or curtailing certain machine-learning workloads when electricity is scarce. By March 19, 2026, Google had integrated a total of 1 gigawatt (GW) of demand-response capacity. That capacity comes through long-term contracts with five US utilities: Entergy Arkansas, Minnesota Power, DTE Energy, Indiana Michigan Power, and the Tennessee Valley Authority (TVA). Then came the bigger move. On October 22, 2026, Google announced a...
