Colorado’s Public Utilities Commission approved a $157 million annual electric rate increase for Xcel Energy on August 20, 2026, handing the utility considerably less than the $225 million settlement its own negotiating partners had endorsed and well below the $356 million the company originally sought.
What the commission approved
The approved increase will raise the average Colorado residential electric bill by about 4.77 percent, or roughly $5 per month, with new rates taking effect August 29, 2026. Small business customers will see a 4.64 percent increase, or about $7.29 more per month.
Bill credits, stronger support for income-qualified households, and added accountability tied to system performance were also approved as part of the final written decision.
For a household using 601 kilowatt-hours per month, the average bill moves to $109.92 from $104.91. The average bill for small commercial customers will rise a little less than 5 percent, to $164.37 per month, for 1,041 kilowatt-hours.
How the case unfolded
Xcel filed the rate case proposal on November 21, 2025, seeking a $356 million increase in annual revenue, which would have represented an estimated 9.9 percent bill increase for average residential customers, roughly $9.94 more per month. Consumer advocates said the original request would have been the largest in state history.
In June 2026, Xcel’s Colorado subsidiary Public Service Company of Colorado, PUC staff, and several other parties filed a comprehensive non-unanimous settlement agreement. The settlement was supported by the company, PUC Staff, Colorado Energy Consumers, Climax Molybdenum, International Brotherhood of Electrical Workers Local Union 111, and Walmart.
The settlement was opposed by AARP, the Colorado Office of Utility Consumer Advocate, and the City of Boulder, as well as Energy Outreach Colorado. As proposed, it would have reduced the company’s request to a $225 million increase, with an estimated 5.86 percent increase for residential customers, or $6.13 per month.
The commission declined to adopt the settlement at the negotiated figure. PUC Chairman Eric Blank noted that despite declining electricity sales since 2021, Xcel had tripled its capital spending over the same period.
He said: “At the end of the day, I remain concerned that if capital spending and rates continue to grow at levels considerably faster than inflation, electricity may simply become unaffordable for many customers.”
Parties can still seek rehearing
The parties to the rate case, including Xcel Energy, the state Office of the Utility Consumer Advocate, and major business customers, have the option to ask for a PUC rehearing and reconsideration of the decision.
Xcel Energy, through its wholly owned subsidiary Public Service Company of Colorado, had built the original filing around a projected $356 million revenue increase for the 2025 test year. The June settlement had proposed a revised rate increase of $225 million, with an estimated 5.86 percent increase for residential customers.
The Colorado decision adds to a national backdrop of heavy utility spending pressure on regulators. The company’s official rate case page confirms the $157 million figure and the August 29 effective date.
Broader rate pressure on consumers
Colorado’s outcome reflects a wider tension playing out at state commissions across the country. As GCN has reported, a record $9.2 billion in US electric and gas rate-hike requests landed in a single second quarter, with regulators approving about 58 cents of every dollar utilities asked for over the prior two years.
The Colorado commission’s decision to award $157 million on a $356 million ask amounts to roughly 44 cents on the dollar, meaningfully below that national average approval rate.
Meanwhile, states with stacked simultaneous proceedings face compounding pressure on household budgets. As GCN has covered, Michigan regulators are handling more than $930 million in simultaneous rate requests from the state’s two major utilities, a situation Colorado’s sequential case structure was designed to avoid. The Colorado PUC’s rate case docket lists the proceeding under number 25AL-0494E.
