Flathead Valley Energy Guide: Solar, Batteries, Backup Power, EV

In short: Kalispell and Whitefish homes are mostly served by Flathead Electric Cooperative, with cheap power (about 9.7¢ per kWh in 2024) but long outages: almost 10 hours per member that year counting major storms (EIA). Sun is the weakest of the Montana areas we cover, about 1,060 kWh a year per kW by our estimate. Backup comes first here.

Below: Flathead Electric’s net metering and generator rules, what the northern sun means for solar, and who issues permits. For statewide rules (the DEQ solar loan, the property tax exemption, licensing), see our Montana energy guide.

Flathead Valley at a glance

• Utilities: in Flathead County, EIA lists Flathead Electric Cooperative (FEC), Glacier Electric, Lincoln Electric and Mission Valley Power. NorthWestern Energy isn’t listed. Your bill shows which serves you.
• Price, 2024 average: FEC about 9.7¢ per kWh for its 63,000 residential members (EIA-861, revenue divided by sales).
• Outages, 2024: FEC 586 minutes per member with major events and 235 without, about 2.7 interruptions a year (EIA-861).
• Sun: 3.62 kWh per square meter per day in Kalispell (NASA POWER, 2001–2020), from 0.8 in December to 7.1 in July. Our rough estimate: about 1,060 kWh a year per kW of panels, 12% less than Billings.
• Top hazards: FEMA’s National Risk Index (December 2025) rates Flathead County “very high” for avalanches, “relatively high” for winter weather and cold waves, and “relatively moderate” for wildfire, lightning, landslides, ice storms and earthquakes.
• Public charging: 21 public ports in Kalispell and 17 in Whitefish (AFDC, October 2026).

Your utility and what it means

Flathead Electric Cooperative is member-owned and sets its own net metering rules. Its solar page (as archived in November 2024) describes:

• Eligibility for renewable systems under 200 kW of generating capacity and under 50 kW of export capacity, after a Small Generation Interconnection Request.
• Surplus credited at the retail rate; in a month when you make more than you use, the net kWh are banked to offset later use.
• A note that a battery could be set to discharge during FEC’s peak hours to help avoid a high demand charge. FEC asks members considering batteries to call first, because its energy advisors “may have rate considerations.”

We couldn’t load FEC’s live site, so confirm the current fee, whether banked kWh expire and any demand charges before you sign. Glacier, Lincoln and Mission Valley Power members should ask their own utility.

Backup power in the Flathead Valley

FEC itself says storms and long outages are “part of living” in its heavily treed territory, and the 2024 numbers agree: almost 10 hours per member with major events, about 4 on ordinary days. Winter weather and cold waves rate “relatively high,” so heat is the first thing to protect, then the well pump in rural homes.

FEC’s generator page (archived November 2024) sets out a useful local option:

• Portable generator: it must connect through a transfer switch. FEC accepts a GenerLink meter-socket transfer switch: you buy it, and FEC’s own staff install it at no charge (FEC requires that they do). It fits 200-amp meter bases only, and FEC’s metering department checks your site first. Call FEC before buying.
• Fixed standby generator: talk to FEC first, get the right permit from the Montana Building Codes Division, and have a qualified electrical contractor wire it with a built-in transfer switch.

Compare generators, generator installation, home batteries and portable power stations, size with the generator sizing tool or battery backup calculator, and read our backup power guide. CPSC’s rules: generators outdoors only, at least 20 feet from the house, exhaust pointed away, carbon monoxide alarms inside.

Solar in the Flathead Valley

Of the Montana areas we cover, this is the hardest for solar savings. NASA’s December average in Kalispell is about a ninth of July’s, and power is cheap. By our rough estimate a 6 kW system makes about 6,350 kWh a year, worth about $615 at FEC’s 2024 average price if every banked kWh is used. Retail-rate credit helps, but payback is slow. Snow on panels cuts winter output further. These are estimates, not quotes.

Solar makes the most sense here paired with backup, or off the grid at cabins where a line extension would be costly; see off-grid power. Check your roof with the solar potential tool and solar savings calculator, and read solar installation, solar costs and how net metering works.

Home batteries

EIA counted 31 of FEC’s 225 home solar systems with a battery in 2024. A battery’s main job here is carrying the house through outages; FEC suggests it may also help with demand charges, so ask an FEC energy advisor about rates before you buy. Keep it in a space that stays above freezing. See battery costs and battery installation.

EV charging

Cheap co-op power makes home charging inexpensive: about $2.90 per 100 miles at 30 kWh per 100 miles and FEC’s 2024 average price (our estimate), more in deep cold. FEC advises asking the utility how much load your service can handle before adding a Level 2 charger. It needs a 240-volt circuit, a licensed electrician and an electrical permit. See EV charger installation and the EV charging cost calculator.

Permits and inspections

• Kalispell: certified by the state for building and electrical permits inside city limits. The Building Department requires permits for building, electrical, plumbing and mechanical work.
• Whitefish (and Columbia Falls): also certified for building and electrical permits inside city limits.
• Rest of Flathead County: electrical permits come from the state Building Codes Bureau (see its certified local governments list).
• Utility approval: FEC must approve an interconnection before a grid-tied system goes live.

Hire a licensed electrical contractor (license lookup on the state page), and check HOA or subdivision rules on panels and standby generators.

Flathead Valley energy questions

Will Flathead Electric install a generator transfer switch?

For a portable generator, yes: FEC installs a GenerLink meter-socket transfer switch at no charge once you’ve bought one, and requires its own staff to do it. It fits 200-amp meter bases only, and FEC inspects first. Fixed standby generators need a state permit and an electrical contractor.

Does Flathead Electric offer net metering?

Yes, for renewable systems under 200 kW of generating capacity and 50 kW of export. Surplus is credited at the retail rate and banked month to month. Ask FEC about fees, demand charges and whether banked kWh expire.

How long are outages in the Flathead Valley?

In 2024, FEC members averaged 586 minutes without power counting major events and 235 without them, over about 2.7 interruptions (EIA). Plan for outages of several hours, longer in big winter storms.

Is solar worth it in Kalispell?

For bill savings alone, it’s slow: weak winter sun and power under 10¢ per kWh mean about $100 a year per kW of panels at most, by our estimate. It’s more attractive paired with backup, or for off-grid cabins.
