Average Generator Price Points
The generator itself usually represents the biggest chunk of your investment. Depending on size and power capacity, prices can vary widely.

- Medium Generators (10-20 kW): $3,500 to $6,200. Suitable for mid-sized homes with higher power needs.
- Large Generators (20+ kW): $7,000 to $25,000+. These units are best for large homes with substantial power requirements.
Generator Brands and Price Points
When it comes to whole-house generators, choosing the right brand can significantly impact both initial cost and long-term reliability. Here’s an overview of popular generator brands across different price ranges, from budget-friendly to premium options.
Budget-Friendly Options
For those looking for reliable yet affordable generators, brands like Champion and Honda are popular choices. These brands offer quality models at a lower price point, making them ideal for smaller homes or for those with basic power needs.
Champion: Known for its user-friendly features and durability, Champion offers models that are easy to maintain and well-suited for backup power needs. Their whole-house generator options start around $2,000, making them one of the more budget-friendly choices for residential backup.
Honda: Renowned for fuel efficiency and longevity, Honda generators come in at a higher budget-friendly price but deliver excellent performance and low maintenance requirements. While often associated with portable units, Honda also provides robust options for whole-home use, typically priced between $2,500 and $4,000.
Mid-Range Options
For a balance between cost and performance, Briggs & Stratton and Cummins provide solid, mid-range
generator options. These brands offer dependable models with added features for better power management and are well-suited for medium to large homes.
Briggs & Stratton: This brand is a popular choice for homeowners who want dependable power without overspending. Briggs & Stratton whole-house generators generally range from $3,500 to $6,000. Known for their efficient engines, they offer models with power management systems to handle multiple large appliances simultaneously.
Cummins: Often recognized for high-performance engines, Cummins provides whole-house generators that are durable, relatively quiet, and feature advanced controls. Cummins models are ideal for those needing reliable backup power for larger homes and can range from $4,000 to $8,000 depending on the capacity.
Premium Options
If you’re seeking top-of-the-line features and are willing to invest more upfront, Generac is the leading brand in premium whole-house generators. Known for their advanced technology, long warranties, and comprehensive power management systems, Generac generators are a popular choice among homeowners with higher power demands.
Generac: Generac has built a reputation as a market leader in home standby power solutions, offering models that range from $5,000 to over $12,000 depending on size and features. Generac generators often come with automatic transfer switches, Wi-Fi connectivity, and remote monitoring capabilities, allowing you to monitor the generator’s status from your smartphone.
The brand also offers a longer warranty and strong customer support, which can make the higher price worth it for those looking for reliability and ease of use.
Generator Installation Cost Breakdown
While the generator itself is costly, installation is another significant expense. Installation costs are affected by labor, location, and any required permits.
Labor Costs
Expect to pay between $2,500 to $7,000 for installation, depending on your generator’s size and the complexity of the setup. Larger generators or those installed in hard-to-reach areas generally take more time and effort, increasing labor costs.
Permit Fees
In Oregon, the cost of permits for installing a whole-house generator can vary widely depending on the city and its specific requirements.
In Gresham, OR, permit fees generally range from $75 to $150, with potential for additional fees if inspections or specific site assessments are required.
In Portland, OR, fees tend to be on the higher side, typically between $100 and $200, as the city often enforces more detailed inspections and stricter building codes, especially in residential areas governed by HOAs.
For smaller cities like Hood River and The Dalles, permit costs are usually lower and more straightforward, ranging from $50 to $100.
Although requirements are often simpler in these areas, it’s still important to confirm if any additional inspections are necessary based on the property type. Homeowners should reach out to their local city or county offices for the most accurate and up-to-date information on permit fees and requirements specific to their location and installation needs.
Transfer Switch Installation
A transfer switch connects your home’s electrical grid to the generator, enabling a smooth transition of power during outages. You can choose between manual and automatic options, with costs ranging from $800 to $2,000 for installation.
Generator Type and Size
Larger, more powerful generators typically cost more than smaller units. Costs also vary by fuel type:
Solar Generators: The most expensive upfront but can reduce long-term energy costs. Solar generators can offset energy costs by 20% to 50% over time, depending on several factors like local sunlight availability, the home's energy consumption, and fuel prices that would have otherwise been incurred with traditional generators. This reduction happens as solar generators eliminate or significantly reduce the need for fuel, which is a substantial recurring cost for other generator types like diesel or natural gas.
Natural Gas Generators: Typically less expensive to operate.
Diesel Generators: Durable but come with higher fueling costs over time.
Concrete Pad
Most generators require a concrete pad for stability. If one isn’t already installed, expect to pay $50 to $75 per square foot for this setup, which can add up depending on the size of your generator.
Fuel Costs
Fuel prices vary by type and region, so it’s essential to budget for this ongoing expense:
- Natural Gas: Roughly $90 per day to run a 20kW generator.
- Diesel or Propane: Expect about $200 per day for the same power capacity.
- Gasoline: Portable gas generators cost around $100 per day, though whole-house models rarely use gasoline.
Whole-House Generator Maintenance Costs
Routine inspections are recommended at least twice a year, especially before seasons with higher power outage risks. Typical maintenance costs include:
- Basic Service (Oil and Filter Changes): $80 to $300.
- Battery Checks and Replacements: Batteries cost around $100 to $200 and should be replaced every few years.
- Comprehensive Inspections: $150 to $500, depending on your generator type.
