Your electric bill is not one number. It is about a dozen.
Xcel publishes its own ten-year rate history for the residential schedule, and that table breaks a bill into thirteen named line items. Service & Facilities Charge. Base Rate Energy Charge. Then a stack of riders and adjustments underneath.
One of those thirteen is fixed. You pay it whether the house is full or empty all month.
Here is what happened to the two biggest ones between January 2014 and January 2024.
The fixed Service & Facilities Charge went from $6.75 to $6.29. Down 6.8%. By Xcel's May 2024 brochure it was back up to $7.10, above where it started, which is worth knowing before anyone makes too much of the dip.
The Base Rate Energy Charge went from 4.604 cents per kilowatt-hour to 7.136. Up 55%.
Same bill, same ten years, two directions. More of what you pay now moves with how much power you actually use.
Which is also the honest limit on what a solar array does. Generation offsets the per-kilowatt-hour side of the bill. It does not touch the fixed monthly charge, and where a production meter is required that adds $2.55 a month. You will still get a bill. It will be smaller.
Three things worth finding on your own bill: the Service & Facility Charge, the riders sitting under the energy charge, and your rate schedule. Add them up and you have your real rate.
