Xcel Energy submitted a proposal on April 2 to the Colorado Public Utilities Commission aimed at addressing the growing demand for electricity from large customers such as data centers. The company said its proposed Large Load Tariff is designed to ensure that existing customers do not subsidize these new, high-demand users.
The move comes as communities across Colorado see increased interest from industries with significant power needs, raising concerns about potential impacts on residential and small business customers. Xcel Energy said the proposal seeks to balance economic development with protections for current ratepayers.
“We understand and share customer concern over the immense energy needs of new, large customers, such as data centers. At the same time we recognize these large customers bring the potential for jobs, investment and innovation to our communities,” said Robert Kenney, president of Xcel Energy—Colorado. “Addressing those concerns by updating rules and policies will help make sure we manage this growth responsibly as we protect customers. This will benefit all customers as we continue to deliver the dependable, safe and low-cost electric service they expect.”
If approved by regulators, the tariff would require big electricity users to pay for infrastructure needed specifically for their operations—including transmission lines, substations, interconnection upgrades, and new generation capacity—so costs are not shifted onto other consumers. The plan also includes requirements such as long-term contractual commitments (typically 15 years or more), minimum monthly payments toward infrastructure costs even if usage ramps up gradually, financial security provisions in case projects are delayed or scaled back, and termination charges if a customer exits service early.
According to Xcel Energy’s statement, a typical data center could generate between $2 million and $16 million in property taxes annually depending on its size and operations. These revenues support local services like schools and emergency response.
The company said it aims to work closely with state regulators “to establish a clear path forward” while ensuring continued protection for residential and small business consumers.
