Google has tested a demand-response system aimed at reducing electricity consumption in its data centers during periods of stress on local electricity grids. This system shifts non-urgent computing tasks to other times and locations, helping to alleviate demands on the grid. It has been tested in locations such as Taiwan, Oregon, and Europe, with plans to roll it out more widely.

The system builds on Google’s existing carbon-intelligent computing platform, which shifts computing tasks to times and places where carbon-free energy is available on the grid. By using this task-shifting capability for demand response, Google can temporarily reduce power consumption in its data centers to support local grids during times of strain.

This approach allows Google to help local grids operate reliably and efficiently while minimizing the impact on its own services, including Search, Maps, YouTube, Google Cloud, and office applications like Gmail. The system was tested during extreme weather events, natural gas shortages, and other grid challenges.

By giving external power utilities the ability to request changes in Google’s computing tasks, the company can contribute to grid stability and reduce the need for new fossil fuel capacity. Demand response, in this context, can serve as a valuable tool to optimize grid performance and reduce the risk of grid overloads.

Google plans to continue using this technique more widely, working with utilities and grid operators to enhance the flexibility and reliability of its demand-response capabilities. This initiative aligns with the broader industry trend of tech companies focusing on sustainable and responsible energy use.
