Net metering / billing
Net Billing (RCP)

Xcel/PSCo (Public Service Co. of Colorado) offers full retail net metering: retail-rate bill credits for the energy you send back, with excess either rolling forward continuously at retail or cashed out yearly at the lower avoided-cost rate — a system sized to your annual usage earns close to full retail value.

Estimates use the average Colorado current utility rate (before solar) of $0.15/kWh (EIA, retrieved Aug 2026) and modeled solar production; individual results vary with your rate, usage, roof orientation, and shading.
