Xcel Energy's Rate Hike Just Got Approved — What It Means for Your Colorado Bill

After nine months of review, the Colorado PUC approved a smaller-than-requested Xcel Energy rate increase on August 20, 2026. Here's what actually changed on your bill and why it keeps happening.

What happened

Xcel Energy filed for a $356 million rate increase — about 9.9%, or roughly $9.94 more per month for the average residential customer — with the Colorado Public Utilities Commission on November 21, 2025 (Proceeding No. 25AL-0494E). In June 2026, Xcel reached a settlement with several parties that would have cut the request to about $225 million (roughly 6%, or $6.13/month), but Colorado's Office of the Utility Consumer Advocate, the City of Boulder, AARP Colorado, and Energy Outreach Colorado all opposed even that reduced figure.

On August 20, 2026, the PUC ruled: a $157 million increase, well below both Xcel's original ask and the settlement figure. For a residential customer using 601 kWh a month, the average bill rises from $104.91 to $109.92 — about $5 a month, or roughly 4.8%.

Why Xcel keeps filing rate cases

This is not a one-off. Xcel has filed several rate cases since 2023 to fund wildfire mitigation — undergrounding power lines, vegetation management — and broader grid modernization across its Colorado territory. The PUC has approved multiple prior increases, and Colorado utilities generally are asking regulators for more to cover rising capital spending on grid hardening and reliability. Even when the PUC trims a request, as it did here, the trend line on the average bill still points up.

What you can do about it

You can't vote down a PUC-approved rate case, but Colorado is one of the few states where you can meaningfully offset it yourself. HB 26-1007 lets residents install a permit-free plug-in solar system up to 395W (or up to 1,920W with a licensed electrician and dedicated circuit) — the highest watt cap in the country — and Colorado is currently the only state where these small systems can participate in full-retail-rate net metering. Denver averages over 3,100 hours of sunshine a year, among the highest totals of any major U.S. city, which makes the math work faster here than in most places.

Calculator AssumptionsSavings estimates are projections based on average sun hours, self-consumption assumptions, and rate escalation scenarios. Actual results vary by roof orientation, shading, usage patterns, and local rate schedules. The federal ITC for residential solar expired December 31, 2025.

Bottom line

The PUC held Xcel to less than half of its original request, but the average Colorado bill is still going up — and it's the third rate increase Xcel customers have absorbed since 2023. Every kWh you generate yourself is a kWh permanently insulated from the next filing.
