Google Data Centre Deal Faces Minnesota Scrutiny as Tech Giants Pledge To Cover Their Energy Costs

Google, Meta and Microsoft are among AI Infrastructure Coalition members pledging to cover the full energy costs created by their data centres, as a Minnesota regulatory proceeding puts that principle under scrutiny.

Google is facing scrutiny in Minnesota over a proposed 15-year electricity agreement for its planned Pine Island data centre. The agreement is being reviewed by the Minnesota Public Utilities Commission (PUC) as regulators examine how its costs could affect other electricity customers.

The Minnesota Attorney General's Office has raised concerns about the proposed agreement with Xcel Energy, saying the utility has not demonstrated that Google would cover all costs attributable to the project. Xcel projects more than $1.1 billion (£834 million) in net benefits for other customers.

The regulatory proceeding is separate from the AI Infrastructure Coalition's voluntary pledge. However, the timing has highlighted a broader question: what does it mean for technology companies to promise to pay the full cost of the power demand created by AI data centres?

Why Is Google's Data Centre Agreement Facing Scrutiny?

The AI Infrastructure Coalition announced five Community Principles on 30 September covering energy costs, water use, community investment, local hiring and engagement with residents.

Google, Meta and Microsoft are among the coalition's members. Under its first principle, participating companies pledged that their data centres would bear the full cost of the energy they use, rather than passing those costs on to other utility customers.

The coalition also said participating companies would build, bring or pay for new generation and transmission needed by their facilities.

The Minnesota proceeding illustrates the questions regulators may face when that principle is applied to a specific utility agreement.

In comments submitted to the PUC on 1 October, Minnesota Attorney General Keith Ellison's office said Xcel had not demonstrated that the agreement would protect other customers from cost shifting or stranded costs.

The office also raised concerns about potential costs if Google uses less electricity than forecast or terminates the agreement early.

Xcel's projection is sharply different. The utility estimates the agreement would deliver more than $1.1 billion (£834 million) in net benefits to other customers, while the Attorney General's analysis indicates roughly $1 billion (£758 million) in net costs.

The Minnesota Public Utilities Commission has not approved either estimate.

What Does Google's Energy Promise Actually Mean?

The dispute highlights the difference between an industry principle and the details of a long-term electricity agreement.

Contracts for large data centres need to account for generation, transmission and other investments required to serve those facilities. If infrastructure is built to support a major new customer, the financial arrangements become important if that customer's electricity demand changes.

Its members also pledged to support local priorities such as schools, roads, hospitals and emergency services. Other commitments cover water use, environmental impacts, local employment and earlier engagement with communities.

But the Minnesota proceeding brings those principles down to the contract level.

The Attorney General's Office has argued that the proposed agreement needs to account for infrastructure investments required to serve Google's facility. It has also questioned potential costs if Google's demand falls below expectations or the company ends the agreement early.

The office has also criticised extensive 'trade secret' redactions in Xcel's filing, saying they make it harder for the public to assess the potential impact on ratepayers.

Could Other Customers Be Left Paying the Bill?

Minnesota law requires the PUC to consider whether costs attributable to very large customers are assigned to the appropriate customer class. It also requires the Commission to consider protections against other customers being placed at risk for stranded costs associated with service to very large customers.

The central disagreement is therefore not simply whether Google has promised to pay.

It is whether the proposed agreement contains sufficient protections to prevent other electricity customers from bearing costs linked to the data centre.

For Google, the Pine Island proceeding offers an early example of how the coalition's energy-cost pledge could be examined through an actual utility agreement.

The figures remain sharply contested. Xcel projects more than $1.1 billion (£834 million) in net benefits, while the Minnesota Attorney General's analysis indicates roughly $1 billion (£758 million) in net costs to other ratepayers.

The Minnesota PUC can approve, modify or reject the proposed Electric Service Agreement. Its review will determine whether the agreement meets the applicable legal requirements and protects other utility customers from costs they should not bear.
