Can Colorado create a clean transition tariff for the load growth era?

Colorado regulators are reviewing a new utility pricing plan aimed at big electricity users like data centers, not homeowners. Xcel Energy wants to set up a "clean transition tariff," a special rate that lets large customers pay extra for power from newer carbon-free technologies that are too costly or risky for the utility to build under normal rules. The idea started in Nevada two years ago, when Google struck a deal with geothermal company Fervo, and utilities in other states have been watching it closely since.

Xcel's version would only apply to power sources that are at least 95% carbon-free, ruling out wind, solar, and standard batteries. Google has been involved in shaping the plan and wants it to also cover things like advanced transmission equipment and smaller, distributed energy sources, not just big power plants. A group representing other large commercial and industrial energy users is pushing to broaden the tariff further, arguing that if it only supports frontier technology, only wealthy tech companies will be able to use it. They see this wave of data center demand as just the start of much larger electricity growth across the economy.

None of this changes rates or programs for typical households right now. It's a policy fight over how utilities charge their biggest customers for new power sources, and how those costs get divided so they don't land on regular ratepayers. Similar proposals are moving through other states, including Minnesota and Michigan, so it's worth watching whether your own state's utility develops something similar down the line.
