Public Service Company of Colorado

Public Service Company of Colorado puts most residential customers on a default Time of Use rate. On-peak hours run 5pm to 9pm on weekdays; everything else, including all weekend and holiday hours, is off-peak, and the off-peak price is well under half the on-peak price in both seasons. Summer prices apply June 1 through September 30 and winter prices October 1 through May 31. Customers can opt out to a flat rate, but an EV owner who charges after 9pm on weekdays or any time on weekends pays the off-peak price without changing plans. Xcel no longer takes new Colorado applications for its EV Accelerate At Home charger rental, which closed on July 14, 2026, and it does not offer a separate EV-only residential rate.

The residential EV Charger and Wiring Rebate covers up to $500 toward a Level 2 charger and the 240-volt circuit, rising to $800 in a Disproportionately Impacted Community and to $2,300 for income-qualified customers who verify income through CLEAResult. Enrollment in Optimize Your Charge is required to claim it. That program asks drivers to do at least 80% of their home charging between midnight and 2pm and pays a $50 bill credit each October. The whole midnight to 2pm window falls inside the Time of Use off-peak period, so following the program schedule also keeps charging at the lower price. The commercial and multifamily infrastructure rebate is a separate program with its own application and per-port amounts.

Public Service Company of Colorado is an investor-owned utility regulated by the Colorado Public Utilities Commission, and its EV programs flow from a multi-year Transportation Electrification Plan approved by that commission. Colorado is a vertically integrated, single-provider market, so customers in the territory do not choose a competitive supplier; the rates and rebates described here are the ones available to them. Service spans both dense Front Range metros and high-altitude mountain counties.
