Google claims that the US transmission system is the biggest challenge to connecting data centers

Google's energy executive said that the most difficult part of powering Google data centers is connecting to the U.S. electric transmission system. In some areas, the wait time to connect can be more than 10 years.

As the world's biggest technology companies race to expand energy-intensive data centres, which are increasingly used to train artificial intelligence and to?roll it out, they are up against the slow-moving power grid of China.

Marsden?Hanna (Global Head of Sustainability and Climate Policy, Google) said that transmission barriers were the biggest challenge on the grid at an event hosted by the American Enterprise Institute.

Hanna stated that "we had one utility tell us to study the timeline of interconnection for 12 years, which is kind?of crazy, but this is what we are seeing."

Hanna stated that in order to reduce the "wait times", the country must address delays with new transmission and utilities should deploy technology to increase the power flow from the existing system.

Google is examining co-location arrangements that could help it avoid some of the long wait times. The company would do this by placing some data centers next to power plants. Colocated arrangements allow for the transmission system to be bypassed and the lengthy wait times that come with it.

Hanna stated that "that's the strategy we're pursuing when it comes to colocation, and our hope is for these resources to be eventually 'grid-connected'." Hanna stated that Google prefers to be connected to the grid.

The topic of colocation is complex and controversial. It has sparked debate about who should pay for the costs and what happens when a power plant diverts its power to a single customer.

Federal and regional regulators are addressing the issue of colocation. They want to establish guidelines for the cost and reliability issues that arise when building data centers near existing power plants.
