Xcel Files $546 Million in Rate Hikes Amid Massive Colorado Spending on Clean Energy Transition

Colorado’s largest utility filed for major increases in both electric and natural gas rates within weeks of each other, a move that could add roughly $17 a month to the average household bill serving both services.

Xcel Energy submitted a natural gas rate case to the Colorado Public Utilities Commission on Dec. 29, 2025, seeking $190 million in additional annual revenue — an 11.4% jump that would raise average residential gas bills by $7.59 a month.

That follows a November filing for a $356 million electric rate boost, adding about $9.94 monthly bill for residential electric customers.

If regulators approve both as requested, the combined hit for dual-service households would be around $17.53 a month, with increases likely taking effect in August 2026 for electric and October for gas.
