How to Choose the Right Generator for Your Home

We’re ready to save your day!

Power outages can strike when you least expect them—during a storm, extreme heat, or simply because the grid is overwhelmed. Regardless of the cause, losing power shouldn’t mean losing peace of mind. That’s where a home standby generator comes in. With the right system in place, your lights stay on, your fridge keeps running, and your home stays comfortable, no matter what.

At Black Hills, we specialize in dependable backup power solutions that are built to last. From expert guidance to seamless installation, our team of certified professionals is here to save your day with honest answers, tailored solutions, and unmatched service you can trust.

Let’s break down how to choose the best generator for your home—so you’re never left in the dark.

1. Sizing Your Generator Correctly

Bigger isn’t always better—and too small won’t do the job.

Finding the right generator starts with determining how much power you actually need. This depends on your home’s size, the appliances you want to power, and how long you expect to rely on the generator during an outage.

Essential Power Only?
 If you’re looking to run a few basics—like your refrigerator, internet, lighting, and a microwave—a smaller backup generator can keep your home functional during short outages. These systems are cost-effective, require less space, and offer quicker installation.

Need Whole-Home Coverage?
 If you work from home, rely on medical devices, or want uninterrupted comfort from your HVAC system and major appliances, a whole-home generator is the smart choice. These units automatically power your entire home and can run for extended periods without interruption.

Smart Sizing Tips:

• Know Your Load: Add up the wattage for each appliance or system you want to support.
• Account for Starting Power: Appliances like AC units and fridges draw extra power when they start up.
• Plan for Growth: If you’re remodeling or installing energy-hungry features (like a pool), future-proof your system now.

Pro Tip: Black Hills technicians use professional load calculations and in-home evaluations to recommend the right system—accurate, efficient, and customized for your home.

2. Choosing the Right Fuel Type

Your generator’s fuel source affects runtime, maintenance, and availability. Here are the top options:

Natural Gas

Ideal for homes with existing gas service, natural gas generators offer unlimited runtime as long as the utility stays active.

Benefits:

• No refueling required
• Low maintenance
• Continuous operation

Considerations:

• Not available in all areas

Propane

If natural gas isn’t available, propane is a clean-burning, efficient alternative.

Benefits:

• Long shelf life
• Cleaner emissions
• Suitable for short to mid-length outages

Considerations:

• Requires an on-site tank and regular refills

Diesel

Diesel generators are powerful and built for longevity—perfect for rural areas or extended outages.

Benefits:

• High efficiency
• Durable and reliable
• Easy fuel storage

Considerations:

• Larger upfront investment
• Needs a dedicated fuel storage area

3. Installation: What to Expect

Installing a generator isn’t plug-and-play—it requires planning, permitting, and professional execution. Here’s what the process looks like with Black Hills by your side:

1. In-Home Assessment

We begin with a detailed inspection of your current electrical system, energy usage, and backup power needs. Our certified technicians recommend the right system and installation site to ensure safe and reliable performance.

2. Permitting & Code Compliance

Every area has different permitting requirements. We handle all necessary permits and ensure your generator complies with local regulations and safety standards.

3. Installation Day

Once permits are in hand, installation typically takes one to two days. Our team handles everything—from electrical hookups to fuel line connections. We finish with a full-function test to confirm your system is ready for anything.

4. Final Walkthrough

We’ll show you how everything works and answer all your questions, so you feel confident and prepared.

At Black Hills, your satisfaction is guaranteed. We don’t just install your generator—we make sure it performs when you need it most.

4. Standby vs. Portable Generators: Why It Matters

Portable generators may work in a pinch, but standby generators offer total peace of mind—without the hassle of setup or refueling in the middle of a storm.

Benefits of a Standby Generator:

• Fully automated startup during outages—even if you’re not home
• No need for extension cords or manual fueling
• Powers critical systems like heating, cooling, medical equipment, and security
• Quiet, clean operation
• Seamless integration with your home’s power supply

A standby generator is a long-term investment in your comfort, safety, and independence. With professional installation and routine maintenance, it’s built to serve you for years to come.
