In short: Wasilla has about 10,300 people and sits in Matanuska-Susitna County. Matanuska Electric Assn Inc serves the county, averaging 23.37¢ per kWh for homes in 2024 (EIA). FEMA rates Matanuska-Susitna County avalanches “very high”. Rooftop solar here makes roughly 740 kWh a year per kW of panels by our estimate, which is on the modest side, so price and incentives matter more.
This page covers what is local to Wasilla: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our Alaska energy guide and the wider area is covered in the Anchorage–Mat-Su guide.
Wasilla at a glance
- Place: Wasilla, Matanuska-Susitna County, Alaska; about 10,318 residents (Census Bureau estimate, July 2024).

- Sun: 2.54 kWh per square meter per day on average, from 0.14 in December to 5.32 in June (NASA POWER). Our rough estimate: about 740 kWh a year per kW of panels.
- Climate: about 0 cooling degree-days and 11,530 heating degree-days a year (base 65°F, NASA POWER), so heating is the big load.
- Top hazards in Matanuska-Susitna County: avalanches “very high”, earthquakes “relatively high” and winter weather “relatively high” (FEMA National Risk Index; overall county risk rated “relatively moderate”).

Your utility and what it means
Matanuska Electric Assn Inc is a member-owned cooperative utility and served about 64,205 home customers in 2024; its 23.37¢ average was below the 28.83¢ statewide average for July 2026. Those are utility-wide averages, not a quote for your address; your own bill is the real number.
For reliability, Matanuska Electric Assn Inc reported 258 minutes per customer without major storms in 2024, more than the statewide figure of 192 (EIA-861). Utility-wide numbers hide a lot: a home at the end of a long rural line usually has more outages than the average.
Net metering, export rates and incentives are set at state level and by each utility. Start with the Alaska guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Wasilla
- Earthquakes (relatively high): Earthquake risk is mainly about secure mounting and gas shut-off for generators; ask the installer to follow local seismic requirements.
- Heating load: a winter outage can stop a furnace blower, boiler pump or heat pump. List what your heat needs to run before choosing a generator or battery.
- Short outages: a portable power station covers phones, Wi-Fi, a CPAP and lights; a home battery switches over automatically.
Size your setup with the generator sizing tool and the battery backup calculator, and compare options in backup power. Generator safety (CPSC): outdoors only, at least 20 feet from the house, exhaust away from doors and windows, never in a garage, and battery-powered carbon monoxide alarms inside. A licensed electrician should install any transfer switch, with a permit; see generator installation.
Solar in Wasilla
By our rough estimate each kW of panels makes about 740 kWh a year in Wasilla (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Matanuska Electric Assn Inc’s 2024 average of 23.37¢, that is about $173 a year per kW if all of it offsets your own use (an estimate, not a promise). Production swings with the seasons: June is the sunniest month at 5.32 and December the dimmest at 0.14, a 38.5-to-1 gap, so a battery or a bigger system helps in winter.
Check your own roof with the solar potential tool, see solar costs and net metering vs net billing, and read the steps in solar installation.
Batteries and EV charging
A home battery earns its place when outages are frequent, when your utility pays little for exported solar, or when evening prices are high; compare in home batteries and battery costs. Wasilla has 12 public charging ports in the federal station list including 6 DC fast, but home charging is cheaper and easier: see the EV charging cost calculator and EV charger installation.

Permits and inspections
Solar, generator transfer switches and EV chargers normally need an electrical permit from the Wasilla building or permitting department, or from Matanuska-Susitna County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Wasilla, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Alaska guide lists the state licensing rules.

Wasilla energy FAQ
Who is my electric company in Wasilla?
Federal data lists Matanuska Electric Assn Inc as the main utility serving Matanuska-Susitna County. Small areas can be served by a different company or a co-op, so confirm on your bill.
How much power will solar make in Wasilla?
About 740 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 4,440 kWh. Shade, roof direction and tilt change this; run your address through the solar potential tool for a better number.
Is a generator or a battery better for winter weather in Matanuska-Susitna County?
It depends how long the outage lasts. A battery is quiet, automatic and good for short outages and for pairing with solar; a standby generator keeps going as long as it has fuel, which suits multi-day events. Many homes use a battery for everyday outages and add a generator for the rare long one.
Will a home battery keep my heat on in an outage?
It can keep a furnace blower, boiler pump or a heat pump running for a while, but long cold outages drain a battery fast without solar to recharge it. Pair it with a generator or wood or propane heat if outages here run for days.
Do I need a permit for solar or a generator in Wasilla?
Almost always an electrical permit for a transfer switch, solar or an EV charger, issued by the city or county where you live. Your licensed electrician or installer normally pulls it. Never connect a generator to your house wiring without a transfer switch.
