How often does Aloha lose power, and is a standby generator worth it?

Washington County, including Aloha, averages 1.5 to 2.5 outage events per year, according to PGE reliability data for the west Portland metro area. Duration varies widely, from a few hours in a summer grid fault to 48 to 72 hours following a winter ice storm or major windstorm. Homes with medical equipment, sump pumps in finished basements, or households with young children and elderly occupants tend to yield the highest returns. If your home lost power during the 2021 ice storm or during December wind events and you were without heat or water for over 24 hours, a whole-home backup generator pays for itself in the first major outage.

What size generator does my Aloha home need?

The size of the generator that your home needs depends on what you want powered during an outage. A partial-load setup protecting your furnace, refrigerator, a few lights, and outlet circuits typically needs 10kW to 13kW. A whole-home generator that handles everything simultaneously, including an electric dryer, multiple HVAC zones, and a home office, typically runs 18kW to 24kW for most Aloha homes in the 1,800 to 2,800 square-foot range. We calculate your load using your main panel's circuit schedule and your average usage data. Do not guess at sizing. An undersized generator running over capacity will short-cycle, overheat, and fail within a few seasons.

What is an automatic transfer switch, and why does it matter?

An automatic transfer switch, or ATS, continuously monitors incoming utility power. When it detects a loss of voltage, it disconnects your home from the utility grid, starts the generator, and routes power to your circuits, all within 10 to 30 seconds. When utility power returns, it transfers back and shuts down the generator. Without an ATS, you need to manually start the generator and connect it, which creates backfeed risk if done incorrectly. Backfeed pushes generator current back onto the utility line, creating a safety hazard for PGE crews working on the outage. Oregon code requires proper isolation from the grid for any permanently installed generator, which is what the transfer switch provides.

Can my existing electrical panel support a whole-home generator?

Most homes in Aloha built before 2000 have 100-amp or 150-amp service panels. A whole-home standby generator that handles 18kW to 24kW of load may require a panel upgrade to 200-amp service first, depending on your current load profile and the panel's breaker capacity. We check the condition of your panel during the site assessment. If a panel upgrade is needed, we scope it as part of the overall project so you get one quote, one permit, and one inspection. Mr. Electric of Beaverton - Tigard handles electrical panel upgrades in Beaverton and the surrounding area, so the work stays with one licensed team.

What fuel source does a standby generator use in Aloha?

Most standby generators in Aloha run on natural gas or propane. NW Natural serves the majority of Aloha residential addresses, so natural gas is the most common fuel choice. A natural gas generator connects directly to your home's gas line and requires a plumber to verify gas meter capacity and line sizing before installation. If your home uses propane, a 500-gallon or larger tank is the standard recommendation for whole-home generator use. Propane requires coordination with your fuel supplier on delivery frequency during extended outage seasons. We handle the electrical side of the installation and work alongside your plumber or gas supplier to arrange the fuel connection.

What Generator Installation in Aloha Actually Involves

Standby generator installation is not a single-step job. When done right, the installation includes site assessment, utility coordination, transfer switch wiring, and a load test. This should all be done before the electrician leaves your property.

The process starts with a generator capacity review. A Beaverton electrician will assess your home's total electrical load and help you decide between a partial-load system that covers critical circuits, like your HVAC unit, refrigerator, and lighting, or a whole-home unit that handles everything simultaneously. Standby generator models in the 11kW to 24kW range are sufficient for most single-family homes in Aloha without oversizing. Larger homes in the 2,500 to 3,500-square-foot range typically need 20kW or more.

After sizing, we select the transfer switch. Most residential installations use an automatic transfer switch, which senses a power outage within seconds and starts the generator without any action on your part. We wire the transfer switch directly to your main electrical panel and set it to your priority circuits if you choose a partial-load configuration. Washington County requires a permit for this work, and our team coordinates the inspection with the county building department. The final step is a load test: we run the generator under real conditions to confirm output, check voltage regulation, and verify the automatic startup sequence works as expected.

Why Choose Mr. Electric of Beaverton - Tigard for Generator Installation in Aloha

Local Electric Knowledge and Expertise

Our team carries the diagnostic tools to run a full load test, read control board fault codes, and verify output voltage at installation. Homes in Aloha tend to have older electrical panels, particularly those built in the 1970s and 1980s near the Cooper Mountain and Farmington Road corridors, and we know when a panel upgrade is needed before a generator goes in.

Automatic Transfer Switch Wiring and Permitting are Handled For You

The automatic transfer switch installation is the most code-sensitive part of any generator project. The Oregon Electrical Specialty Code requires proper bonding, grounding, and a service disconnect accessible to utility crews. Mr. Electric of Beaverton - Tigard handles the entire permitting process, from the beginning of the application to the final inspection sign-off. This way, you don't have to coordinate with Washington County's building department or track down permit status. This also keeps the installation legal, keeps your homeowner's insurance valid, and protects you if you ever sell the home.

Upfront Pricing, No Hourly Billing

We quote generator installation by the job, not by the hour. Before any work begins, you receive a written estimate covering equipment, labor, permitting fees, and the load test. Nothing gets added after the fact. If the scope changes, we will discuss it with you before proceeding. That is how the Neighborly Done Right Promise^® works in practice.
