Longmont Power & Communications Solar Guide: Net Metering and Local Rules

If you live in Longmont and want to go solar, your electricity comes from Longmont Power & Communications (LPC), the city owned municipal utility. That matters, because Longmont Power solar works a little differently than solar on Xcel or on one of the rural co-ops. LPC sets its own net metering terms, the City of Longmont handles your solar permit, and the whole process is local from start to finish. This guide walks through how it all fits together so you know what to expect before you sign anything.

ProGreen Solar is headquartered right here in Longmont, at 1030 Boston Avenue. This is our home turf. We have walked the permit counter, pulled the meter, and flipped on systems all over town, so the details below come from doing the work, not from a national playbook.

Who is Longmont Power & Communications

LPC is a municipal utility owned by the City of Longmont, not an investor owned company. It buys its electricity wholesale from the Platte River Power Authority, the same not for profit wholesale generator that serves Fort Collins, Loveland, and Estes Park. Each of those four cities runs its own retail utility, sets its own rates, and runs its own net metering and rebate programs, while Platte River handles generation and broader clean energy and grid programs behind the scenes.

For a fuller picture of how that wholesale and retail split works across the region, see our Platte River Power Authority solar guide. The short version for Longmont homeowners: your day to day solar relationship is with LPC, and LPC is responsive and local because it answers to the city, not to shareholders.

How LPC net metering works

Net metering is the billing arrangement that makes rooftop solar worthwhile. When your panels produce more power than your home is using, the extra flows back onto the grid and your meter records it as a credit. When you pull power at night or on a cloudy day, you draw down those credits. In effect, the grid acts like a bank for the energy you generate.

With Longmont Power, the practical points to understand are:

• Credit for exports. Excess generation you send back to LPC earns a bill credit that offsets the energy you later consume.
• System sizing. Utilities generally want your system sized to your own annual usage rather than to oversell power back to the grid, so a good installer designs around your past 12 months of bills.
• Interconnection. Before your system can turn on, LPC reviews and approves the interconnection application and sets the meter so it can measure energy flowing both directions.
• Fixed charges still apply. Even with solar, you remain a connected customer, so a monthly service charge stays on the bill to keep you tied to the grid.

Net metering rules, credit rates, and any fees can change over time. Because LPC is a municipal utility and updates its tariffs periodically, treat the specifics above as the general structure and confirm the current LPC net metering terms, sizing limits, and any rollover rules directly with Longmont Power before you commit. We verify the live numbers for every Longmont customer as part of the proposal.

Why net metering favors Longmont homeowners

One advantage of a municipal utility like LPC is stability. Investor owned utilities across Colorado have moved toward more complex time based pricing and have trimmed the value of solar exports in recent years. Municipal utilities tend to move more slowly and stay closer to a straightforward, retail rate style of net metering, which keeps the math on a residential solar system simpler to understand. That does not mean the terms are frozen forever, but it does mean Longmont homeowners often face fewer surprises than customers on larger investor owned systems. Pairing your panels with a home battery is still worth considering if you want backup power during outages or plan to add an electric vehicle or heat pump, since those choices change how much energy you use and when.

Going solar in Longmont: the permit and process

Going solar in Longmont involves two approvals running in parallel: a building and electrical permit from the City of Longmont, and an interconnection approval from LPC. As your installer, ProGreen handles both filings for you. Here is the typical sequence.

1. Site evaluation and design. We review your roof, shading, electrical panel, and a year of energy use, then design a system sized to your home.
2. Permit and interconnection submission. We submit the city permit package and the LPC interconnection application together.
3. Installation. Once permits are approved, the physical install usually takes a day or two for a typical home.
4. City inspection. A Longmont inspector verifies the work meets code.
5. Permission to operate. After inspection passes and LPC sets the net meter, you get the green light to switch the system on.

If you want to compare how permitting differs from county to county across the region, our guides to Colorado solar permits by county and the neighboring Boulder solar permit process show how local rules vary just a few miles apart.

Local permitting notes for Longmont

Longmont permits residential solar through its own building division, and inspection timelines move at a steady, predictable pace for a city this size. A few practical reminders:

• Have your electrical panel assessed early. Older homes may need a service or panel upgrade before solar can be added safely.
• If your home is in a historic district or has an HOA, factor in any architectural review on top of the city permit.
• Keep your past utility bills handy. Accurate usage history leads to a correctly sized system and a smoother interconnection review.

Because the city, the inspector, and the utility are all part of the same local government, the handoffs between permit approval, inspection, and interconnection tend to be coordinated rather than scattered across separate organizations. That is one of the quiet benefits of going solar in a municipal utility town: fewer parties, clearer lines of communication, and a process that a local installer can shepherd from one office to the next.

Why a local Longmont installer matters

Solar is a 25 year plus relationship with your roof and your utility, so the company you choose matters as much as the panels. Because ProGreen is based in Longmont, we know the LPC interconnection staff, the city inspectors, and the quirks of Front Range weather, from spring hail to high altitude sun. We are a licensed Colorado electrical contractor, and we are here long after the install if you ever need service, a monitoring check, or help reading a bill.

Being local also means faster answers. When a question comes up about an LPC tariff change or a permit detail, we can pick up the phone with people we already work with rather than routing through an out of state call center.

Getting started with Longmont Power solar

The best first step is a simple one: pull your last 12 months of LPC bills and let us model a system around your actual usage. We will confirm the current Longmont Power net metering terms, design a right sized array, and handle every permit and interconnection filing on your behalf. If you are weighing whether solar pencils out for your specific Longmont home, our residential solar team can put real numbers in front of you with no pressure. As your hometown installer, we would be glad to show you what going solar in Longmont looks like.
