What stacks on a Fort Collins battery in 2026
Take a single 13.5 kWh Tesla Powerwall 3 at about $19,000. The Fort Collins Utilities rebate works out to about $4,050 (13.5 × $300). Colorado’s residential storage credit is 10% of the purchase price for equipment, tax and freight — not labor or permits — so the credit is somewhat less than $1,900, and it applies only to tax years through 2026. Batteries are also exempt from state sales tax.
An Enphase IQ Battery setup at about $17,000 for 10 kWh would earn about $3,000 from the city, and a 9 kWh SigEnergy system at $15,500 about $2,700. Two Powerwalls (27 kWh, about $31,000) would hit the $6,000 cap. These are illustrations, not quotes; verify current terms before you rely on them.
The deadline that actually matters
Colorado’s 10% storage credit applies to tax years 2023 through 2026 and the statute repeals January 1, 2027. A battery installed in 2027 won’t qualify under current law. Fort Collins’ own six-month install window after rebate reservation is the other clock to watch.
Backup: what a Fort Collins battery does in an outage
A battery that’s set up for backup keeps chosen circuits running when the grid is down — furnace blower, fridge, Wi-Fi, a sump pump. A single 13.5 kWh unit typically covers essentials overnight; running a whole home with central AC takes more capacity. We’d rather size you honestly for the loads you care about than sell a second unit you won’t use.
FAQ
Questions we hear
Does the Fort Collins battery rebate require solar?
Our research notes indicate the battery rebate is for solar-paired systems with at least 6 kWh of capacity. Confirm on Fort Collins Utilities’ current program page, since terms can change year to year.
Can I add a battery to the solar I already have in Fort Collins?
The city’s program allows up to $7,500 combined for additions to existing systems as well as new ones. We add batteries to solar we install; we don’t take over or service other companies’ systems, so for an older third-party array we’d confirm compatibility first.
Which battery brands do you install in Fort Collins?
Tesla Powerwall 3, Enphase IQ Battery and SigEnergy. All three must also be on the California Energy Commission equipment list to qualify for the city rebate.
Is it worth buying a battery before the end of 2026?
If you were already leaning toward one, finishing the install in 2026 preserves Colorado’s 10% battery credit, which ends after tax year 2026 under current law. Don’t buy a battery only to chase a credit if it doesn’t fit your needs.
