Experiencing a power outage can majorly disrupt your daily activities. However, with a properly sized standby generator, your home can continue to be a haven of comfort and functionality. Knowing what size generator your home requires involves detailed planning and an understanding of your energy needs.
At Tevis Energy, we offer professional advice to guide homeowners through selecting and installing the perfect standby generator. This article details the essential steps on how to size a standby generator, equipping you with the knowledge to protect your home and maintain your lifestyle during power outages.
How To Size a Standby Generator: A Comprehensive Guide for Homeowners
Grasping how to choose the appropriate generator is crucial for keeping your home operational during crucial times. Let’s delve into the important factors to consider when determining the correct size for a standby generator.
The Importance of Correctly Sizing a Backup Generator
Ensuring your standby generator is accurately sized is critical for maintaining a safe and efficient power supply during outages. A generator that is too small will not be able to supply enough electricity, which can result in overloaded circuits, possible harm to delicate appliances, and repeated system shutdowns.
Conversely, a generator that is too large leads to excessive fuel usage, accelerated wear and tear, and higher maintenance expenses. By aligning the generator’s capacity with your home’s precise energy needs, you guarantee steady performance, minimized waste, and dependable functionality precisely when necessary.

Determining Your Home’s Energy Requirements
To accurately size a standby generator, start by identifying the appliances and systems critical during a power outage. Focus on essentials like your HVAC system, refrigerator, lighting, sump pump, and necessary medical devices. These are vital for maintaining safety, comfort, and functionality throughout prolonged power interruptions.
Then, tally up the total wattage needed to operate these critical items. You must account for their running wattage (power needed for continuous operation) and starting wattage (initial power surge upon activation). For instance, refrigerators generally operate on 600-800 running watts but can demand up to 1,200 watts at startup. Likewise, a typical central air conditioner requires about 3,000 running watts, with up to 6,000 watts needed to start.

Peak vs. Sustained Power Requirements
Understanding the difference between a generator’s capability to manage peak power (startup wattage) and sustained power (running wattage) is vital. The generator should handle the initial high demand of appliances seamlessly and maintain the continuous load effectively. Managing these power needs correctly ensures consistent operation and prevents undue stress on the generator.
Types of Whole-House Generators & Their Power Capacities
Selecting the appropriate generator is contingent on your home’s backup power needs.
- Whole-House Generators: These units supply comprehensive backup power to every system in your home, including HVAC, lighting, and appliances, making them suitable for larger homes or those needing complete coverage during power outages. Their capacities typically span from 22 kW to 48 kW or more, tailored to your specific energy requirements.
- Partial Home Generators: These generators deliver power to chosen circuits or crucial loads like refrigerators, sump pumps, and lights. They are a budget-friendly solution for homes with more modest backup power necessities. Based on the selected circuits, capacities generally vary from 8 kW to 20 kW.

Factors to Consider When Sizing a Power Generator
Choosing the appropriate generator involves evaluating several aspects influencing its efficiency and suitability for your home.
Home Size and Layout
The dimensions and configuration of your home significantly dictate your power requirements. Larger residences need more robust generator capacities to provide sufficient coverage, particularly if the home spans multiple levels or includes separate buildings such as garages or workshops. It’s crucial for the generator to power all necessary circuits throughout these areas consistently.
Weather and Seasonal Factors
The climate in your area and the seasonal needs significantly influence your energy usage. Homes in colder climates may need to power heating systems, electric space heaters, and heated flooring, all of which consume a lot of electricity.
Conversely, residences in warmer regions often depend on air conditioning and dehumidifiers, which similarly elevate power requirements. A well-sized generator must accommodate these seasonal variations in energy demand.

Future Energy Needs
It’s crucial to consider future energy demands when choosing a generator. Integrating electric vehicle (EV) chargers, high-capacity appliances, or advanced smart home systems can substantially raise your energy requirements in the future. Opting for a generator with a bit more capacity than currently necessary ensures it remains effective, even with potential upgrades.
Choosing the Right Whole-House Generator Fuel Type and Assessing Availability
The type of fuel you select for your generator—natural gas, propane, or diesel—greatly affects its efficiency and sizing needs. Natural gas and propane are preferred for residential settings because of their cleaner burning and straightforward integration into home systems, though their availability may differ based on your location.
Diesel generators are known for their higher efficiency and robustness but necessitate more storage capacity and fuel management. Being informed about fuel choices helps ensure the generator fulfills your energy requirements and logistical considerations.

Essential Tools and Resources for Precise Backup Generator Sizing
Correctly sizing a standby generator demands meticulous planning, and several tools are available to help homeowners. Online generator sizing calculators can offer preliminary estimates by considering typical household appliances and systems.
However, these should not replace professional assessments. Depending exclusively on these calculators might lead to mistakes, like underestimating your power requirements or missing vital systems, potentially leading to subpar performance when you need it most.
Professional energy assessments, like those provided by Tevis Energy, guarantee accurate calculations customized to your home’s needs. Expert evaluations consider comprehensive energy consumption, anticipated future demands, and correct installation practices, delivering dependable advice on the optimal generator size for your residence.
Key Considerations for Standby Generator Installations
Correct installation of standby generators is crucial for ensuring both safety and effectiveness.
Space and Placement Considerations
The physical dimensions of the generator dictate its placement, necessitating sufficient space and clearance from walls, windows, and vents to promote safe operation and optimal airflow. It’s essential to mount generators on a flat, stable surface, often a concrete pad, positioned to reduce noise and exhaust effects on the home.
Local Codes and Regulatory Compliance
Adhering to local codes and regulations is critical for generator installation. You might need to secure permits, and the installation must conform to specific safety and zoning standards. Compliance with these regulations prevents legal complications and ensures the generator operates safely and reliably. Working with professionals well-versed in local requirements can streamline the process and guarantee that all aspects meet the necessary codes.

Standby Generator Sizing: Common Questions
What Are the Risks of an Undersized Standby Generator for My Home?
An undersized generator will not cope with your home’s energy requirements, leading to overuse and possible malfunction or complete failure. This can result in repeated outages and harm to appliances connected to the system and may even reduce the generator’s lifespan. Correct sizing is crucial to provide an uninterrupted power supply and prevent system overload.
