Xcel proposes new rate scale for data centers to shield consumers from added power costs

Xcel Energy has introduced a special electricity tariff designed for new, high-power-consuming data center customers in Colorado. This proposal, unveiled Thursday, aims to prevent an increase in electricity rates for existing residential and small business consumers, who might otherwise bear the costs associated with the significant new power infrastructure required by data centers. The Colorado Public Utilities Commission (PUC), the state's largest electricity provider with 1.6 million customers, mandated Xcel Energy to create such a tariff due to concerns over rising demand. Public Service Company of Colorado, an Xcel Energy subsidiary, forecasts that these "large-load" customers will account for two-thirds of its new electricity demand, necessitating 950 megawatts of additional generation capacity over the next five years. The rapid growth in data center construction, particularly driven by artificial intelligence, is highlighted as a national trend. Industry analysts like Rystad Energy note that global data center capital expenditures are surging, while CBRE reports record U.S. electricity demand from data centers and historically low vacancy rates. Consumer advocates, including Joseph Pereira, director of the Colorado Office of the Utility Consumer Advocate, have expressed support for Xcel's proposed tariff, viewing it as a positive step towards protecting other customer classes from undue financial burden. A bill addressing these issues is also currently pending in the state legislature, underscoring the broader governmental attention to data center power consumption challenges. The PUC must ultimately approve the proposed rate structure.
