Tech Giants Dispute Costs for U.S. Grid Upgrades

Major technology companies are disputing the extent of their financial responsibility for electrical grid upgrades required to support AI data centers. While Amazon, Google, Meta, and Microsoft signed a Ratepayer Protection Pledge in March to cover infrastructure costs, they now oppose the "but-for" standard. This standard would require firms to pay for any shared upgrade that would not have been constructed without their presence.

A Senate investigation led by Senators Elizabeth Warren, Chris Van Hollen, and Richard Blumenthal found that these tech firms intend to pay only for infrastructure serving their own facilities rather than shared grid upgrades. In North Carolina, Duke Energy reached a settlement requiring data centers to prepay for dedicated equipment and provide letters of credit for shared upgrades.

Further tensions have emerged regarding power capacity. PJM has proposed that data centers of 50 MW or more must provide their own power capacity by June 2027 or face priority power cuts. Google and the Data Center Coalition have urged the Federal Energy Regulatory Commission to reject this plan, warning that such requirements would "chill investment."
