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 3pm to 7pm on weekdays, with a mid-peak block from 1pm to 3pm; everything else, including all weekend and holiday hours, is off-peak. Winter rates apply October through May and summer rates June through September. For EV charging, drivers can instead take EV Accelerate At Home, which adds a six-hour overnight off-peak window from midnight to 6am at a low rate for the vehicle's charging.

The residential EV Charger and Wiring Rebate covers up to $500 for the 240-volt circuit, permit, installation, and an eligible Level 2 charger, rising to $1,300 for income-qualified customers who verify income through Xcel's partner. Enrollment in the Optimize Your Charge managed-charging pilot is required to claim the rebate, and Optimize Your Charge pays a $50 bill credit each October for charging off-peak. The commercial and multifamily infrastructure rebate is a separate program with its own application.

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.
