In short: Oregon City has about 38,300 people and sits in Clackamas County. Portland General Electric Co serves the county, averaging 18.19¢ per kWh for homes in 2024 (EIA). FEMA rates Clackamas County earthquakes “relatively high”. Rooftop solar here makes roughly 1,070 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 Oregon City: its utility, outage records, sunshine, weather risks and charging. Statewide rules such as net metering, incentives and electrician licensing are in our Oregon energy guide and the wider area is covered in the Portland, OR guide.
Oregon City at a glance
- Place: Oregon City, Clackamas County, Oregon; about 38,327 residents (Census Bureau estimate, July 2024).
- Utility: Portland General Electric Co (investor-owned). Homes paid an average 18.19¢ per kWh in 2024 (EIA-861); the average customer lost 133 minutes of power on normal days and 772 counting major storms, with 0.8 interruptions a year (utility-wide, not just Oregon City).
- Sun: 3.67 kWh per square meter per day on average, from 0.98 in December to 6.82 in July (NASA POWER). Our rough estimate: about 1,070 kWh a year per kW of panels.
- Climate: about 320 cooling degree-days and 5,220 heating degree-days a year (base 65°F, NASA POWER), so heating and cooling both matter.
- Top hazards in Clackamas County: earthquakes “relatively high”, cold waves “relatively high” and river and heavy-rain flooding “relatively high” (FEMA National Risk Index; overall county risk rated “relatively high”).
- Public charging: 68 ports at 43 locations in Oregon City, none of them DC fast (AFDC, October 20, 2026).
Your utility and what it means
Portland General Electric Co is an investor-owned utility and served about 828,857 home customers in 2024; its 18.19¢ average was above the 15.97¢ 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, Portland General Electric Co reported 133 minutes per customer without major storms in 2024, more than the statewide figure of 131 (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 Oregon guide and then ask your utility for its current interconnection steps before you sign anything.
Backup power in Oregon City
- Earthquakes (relatively high): Earthquake risk is mainly about secure mounting and gas shut-off for generators; ask the installer to follow local seismic requirements.
- Cold waves (relatively high): Cold waves raise demand and can cause both outages and frozen pipes. Keep at least one room warm with a battery-run heater circuit or a generator.
- 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 Oregon City
By our rough estimate each kW of panels makes about 1,070 kWh a year in Oregon City (NASA sunshine data times 365 days times 0.80 for system losses). Valued at Portland General Electric Co’s 2024 average of 18.19¢, that is about $195 a year per kW if all of it offsets your own use (an estimate, not a promise). Production swings with the seasons: July is the sunniest month at 6.82 and December the dimmest at 0.98, a 6.9-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. Oregon City has 68 public charging ports in the federal station list (none of them 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 Oregon City building or permitting department, or from Clackamas County if you live outside city limits, and often a utility interconnection approval. We have not verified a local permit page for Oregon City, so check the city and county websites or ask your electrician, who will know the process. Hire only a licensed electrician or installer; the Oregon guide lists the state licensing rules.

Oregon City energy FAQ
Who is my electric company in Oregon City?
Federal data lists Portland General Electric Co as the main utility serving Clackamas 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 Oregon City?
About 1,070 kWh a year per kW of panels by our estimate, so a 6 kW system would make roughly 6,420 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 cold waves in Clackamas 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.
Do I need a permit for solar or a generator in Oregon City?
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.
