Xcel filed a Texas tariff to lock data centers into 15-year contracts with exit fees

The tariff that names who pays

On September 28, Xcel Energy asked the Public Utility Commission of Texas to approve a large-load tariff↗ making data centers and other huge users pay for the transmission, substations, interconnection upgrades and new generation their projects require ¹². The terms read like a lender's covenant: commitments typically of 15 years or more, financial security if a project is delayed or scaled back, minimum monthly payments while usage ramps up, and exit charges to recover project-specific infrastructure if a customer walks early ². Xcel says it has already advanced large-load tariffs in other states and expects to file next in New Mexico ¹. "These projects can drive economic opportunity in the communities we serve, but it's critical that growth is handled the right way," said Brad Baldridge, interim president of Xcel Energy↗ Texas and New Mexico ¹.

The fight that produced it

The filing answers a live political fight over who pays for AI power. In Minnesota, Attorney General Keith Ellison's office argues Google's Pine Island agreement↗ could leave Xcel's other customers with roughly $1 billion in net costs, against Xcel's projection of more than $1.1 billion in net benefits; the project sits on hold pending an environmental review ³⁴. In Colorado, Xcel's own April tariff plan for loads above 50 MW covers an estimated 2 GW of new data-center demand by 2031, with poles and wires alone possibly costing more than $1 billion, company estimates show ⁵. And from October 6, Colorado households pay $5.16 more a month for gas under a $123 million settlement regulators cut from a $190 million ask ⁶.

Ohio already ran this experiment

The template exists. In 2025, Ohio approved AEP's data-center tariff↗: qualifying facilities pay for at least 85% of contracted capacity for up to 12 years, with collateral and exit charges ⁷. AEP Ohio said in February it holds 17,861 MW of data-center contracts through 2035, about 70% above its historic peak demand ⁷. Per the Ohio Consumers' Counsel, Amazon, Google, Microsoft and Meta fought that binding tariff and backed a softer alternative; on September 30 they signed a voluntary pledge to cover their full energy costs↗ ⁸⁴. The pledge is voluntary. The tariff is not.

The capital is already committed

Xcel is spending like a company that expects the fight to break its way: quarterly capital spending has roughly doubled since 2023 while operating cash flow has gone sideways, leaving the buildout funded increasingly by debt and equity rather than the meter ⁹.

The quiet third leg

On October 6, Xcel also agreed to exit Michigan↗: 6,000 gas customers to SEMCO, 9,000 electric customers to Upper Peninsula Power, 15,000 customers across two counties in all, closing in 2027 with financial terms undisclosed ¹⁰¹¹. Small legacy territory out, contracted AI load in: read together, the week is one capital reallocation.

Three regulators, three verdicts

Three regulators now hold the thesis: the PUCT on the Texas tariff, the Colorado PUC on the April plan by year-end, and the Minnesota PUC on the Google agreement ¹⁵³. Approval hands Xcel a data-center pipeline that arrives contracted rather than contested; nothing in the record yet says CenterPoint or DTE follow the same path. Every utility with a data-center queue faces the same fork: contract the load, or litigate the bill.
