Aspen Electric or Holy Cross?
Aspen Electric serves a defined area in and around the city; much of the surrounding valley, and parts of town, are on Holy Cross Energy. The rules below apply only inside the Aspen Electric service area. Holy Cross has its own battery program and solar rules, covered on its own page.
A strict 100% cap
Aspen Electric limits annual solar generation to 100% of the premises’ three-year average use — tighter than the 120% or 200% caps common elsewhere in Colorado. Using a three-year average smooths out a single unusual year, but it also means planned loads like a new EV or heat pump won’t count until they show up in your history. We size to the cap, not over it.
The two-meter setup
Every system needs two meter sockets: one for the city’s net meter and one for a production meter, both owned by the city. The production meter has to be within 10 feet and in line of sight of the utility meter, with inverter output wired to its load-side terminals. On older homes or tight exterior walls, finding space for that layout can drive the design.
Batteries
Solar with storage uses a separate interconnection agreement, and the battery’s nameplate size, discharge capacity and number of units go on the application at permit time. Tell us up front if you want storage, even later — it’s easier to plan the equipment layout once.
Rebates & programs
Programs change often. Status shown is what we could confirm on the date listed — always check with the program before you count on it.
City of Aspen rebate program
Status unconfirmedThe City of Aspen has offered rebates covering solar PV along with heat pumps and efficiency measures. A solar rebate of up to $2,250 is cited by third parties; we haven’t confirmed the current amount or status.
FAQ
Questions we hear
How much solar can I install on Aspen Electric?
Enough to produce up to 100% of your home’s three-year average energy use, no more.
Why does Aspen require two meters for solar?
The city meters both net energy at the service and total solar production. Both meters are city property, and the production meter must be within 10 feet and in line of sight of the utility meter.
Who do I contact about solar on Aspen Electric?
City of Aspen Utilities handles solar permitting questions. Applications go through the city’s permit portal with an Electric Permit and Electric Load Form.
Is all of Aspen on the city’s electric utility?
No. Much of the area is served by Holy Cross Energy. Check your bill before planning around Aspen Electric rules.
