Where City of Longmont sits
It serves 40,855 residential customers in Colorado. At 12.30¢ per kilowatt-hour it is one of the cheaper places to buy electricity in Colorado, 23.9% under the statewide average of 16.16¢.
Consumption here is below the national norm at 691 kilowatt-hours a month against 871, which softens the effect of the rate on the final bill.
Owned by the city it serves and governed by a local board rather than the state commission. No shareholder return is built into the rate. That matters because a bill is not only the cost of generating electricity: it also carries the cost of the network, and who owns that network changes how it is paid for.

How often the power goes out
In 2024 the average City of Longmont customer went 19 minutes without electricity across 0.47 interruptions. The median across the 941 utilities that report this is 185 minutes.
That is markedly better than typical. Short outage durations usually mean an underground or heavily automated network, and they are expensive to achieve, which is part of why reliable systems often carry higher delivery charges.

1,010 residential customers had net-metered solar in 2024, totalling 7.06 megawatts. That works out to 24.7 installations per thousand customers, against a median of 8 across the utilities reporting it.
Adoption is above the national median, which generally tracks the retail rate more closely than it tracks sunshine. What exports are actually worth.
