- Google and Xcel Energy have proposed adding 1,400MW of wind, 200MW of solar and 300MW of battery storage to support a planned 780MW AI data centre in Minnesota.
- The agreement aims to protect existing electricity customers from infrastructure costs, but experts question whether utilities and data centre operators could reduce costs further by using existing grid capacity.
Google plans to support a major expansion of renewable energy and battery storage in Minnesota through a proposed agreement with Xcel Energy to power a 780-megawatt (MW) artificial intelligence (AI) data centre in Pine Island. The proposal would add 2.1 gigawatts (GW) of wind, solar and battery capacity to the grid, exceeding the data centre’s planned capacity as the companies seek to improve electricity reliability and reduce carbon emissions.
The project comes as AI data centres drive electricity demand growth across North America, prompting utilities to expand generation and transmission infrastructure. Google says the agreement could help finance grid upgrades while advancing its goal of operating on carbon-free energy around the clock by 2030.
Renewable Energy and Storage to Support AI Demand
Under the proposed arrangement, Google would finance the addition of 1,400MW of wind power, 200MW of solar capacity and 300MW of battery storage. The combined 1,900MW of renewable generation and storage capacity would exceed the data centre’s 780MW demand, reflecting the intermittent output of wind and solar power and the need to balance electricity supply.
Xcel Energy says the new capacity would serve customers across the local area rather than Google alone. The upgrades would also support the grid’s transition towards cleaner electricity.
Amanda Peterson Corio, Google’s global head of energy and power, said the growth of AI infrastructure presented an opportunity to finance improvements to ageing electricity systems.
“The timing of this industrial revolution couldn’t be more perfect,” she said. “It’s right at the time when we needed capital to fix aging infrastructure in the United States.”
Contractual Safeguards Aim to Protect Electricity Customers
The proposed agreement includes minimum demand charges and early termination fees to ensure Google contributes to the infrastructure costs even if its electricity needs decline.
Google would pay for at least 75% of its contracted capacity, even if it consumes less electricity. If the company terminates the agreement early, it could owe up to eight years of minimum demand charges.
Amanda Rome, Xcel Energy’s executive vice president and chief customer officer, said these provisions would help prevent the utility from building infrastructure without sufficient demand or a customer to cover the costs.
“Nobody wants to have a big buildout and then have nowhere for that power to go and nobody to pay for that power,” Rome said.
The Minnesota Public Utilities Commission must approve the agreement before it takes effect.
Experts Question the Scale of New Grid Construction
The North American Electric Reliability Corporation expects data centres to account for most projected electricity demand growth over the next decade. Meanwhile, ageing transmission lines and power transformers have increased the need for grid investment across the United States.
However, some experts argue that developers could reduce infrastructure costs by building smaller data centres in locations where existing grids have spare capacity.
Jigar Shah, a partner at clean energy consultancy Multiplier, said using existing grid infrastructure to accommodate new demand could lower electricity rates by spreading fixed system costs across more customers.
Utility watchdog David Pomerantz, executive director of the Energy and Policy Institute, also questioned the financial incentives that encourage utilities to build new infrastructure. He said utilities typically earn returns of around 10% on investments financed partly through shareholder capital.
Pomerantz argued that data centre operators could help lower consumer bills by financing infrastructure at cheaper rates than utilities. However, he noted that this approach could conflict with utilities’ financial incentives.
Balancing AI Growth With Affordable, Reliable Power
The Google–Xcel proposal illustrates how technology companies could help finance renewable generation, battery storage and grid upgrades as AI increases electricity demand. Its effectiveness will depend on regulatory approval, implementation and whether the agreement delivers the promised benefits to existing customers.
While experts see potential in using AI investment to accelerate cleaner power infrastructure, they also stress the need to assess existing grid capacity and ensure that expansion costs do not place unnecessary pressure on electricity consumers.
