When the power goes out, generators are expected to take over immediately. What many homeowners don’t think about is how that happens if the house already has no electricity. So, if you’ve wondered if you need electricity to run a generator, the answer is no! Generators operate independently from the utility grid and use a different fuel source than electricity. After the engine starts, the unit generates its own power. Fuel is what makes that possible, which is why generator fuel type plays a key role in choosing the right system for a New York home.

If you live in Rochester, Buffalo, Syracuse, or anywhere nearby, electrical outages can happen during storms, wind events, or heavy snow. Knowing how your standby generator gets its power helps you feel more confident when those moments arrive.

Do Generators Need Electricity to Run

Generators run the same way small engines run. They use fuel, combustion, and an alternator to generate electricity. Once the generator starts, it does not rely on the grid at all. It becomes its own power source. The engine keeps spinning, the alternator keeps producing electricity, and your home stays powered even when everything around you is dark.

The important part is making sure your generator has good fuel flow and regular maintenance. With those in place, it runs on its own.

How Standby Generators Turn On During an Outage

Most people never touch their standby generator during an outage. The automatic transfer switch handles everything. The moment the power goes out, the switch senses the loss and signals the generator to start. A few seconds later, the generator sends electricity into your home’s circuits. When utility power returns, the switch transitions everything back automatically. You do not need to step outside in the middle of a storm or flip any buttons.

Modern generators are designed to take over quietly and reliably.

Overview of Generator Fuel Types

Standby generators in New York generally run on one of three fuels. Each has its own advantages, and the best choice depends on your home’s setup.

Natural Gas

This fuel comes directly from your home’s existing gas line.

Propane (LP)

Stored in a tank on your property, which makes it easy to control your own fuel supply.

Diesel

Used in heavy-duty generators and larger home systems.

Each option can power a standby generator well, but they all behave a little differently.

How Natural Gas Generators Work

Natural gas is a popular choice because it is simple and steady. The fuel supply is already connected to the house, and homeowners do not need to worry about refilling tanks. Natural gas burns cleanly, starts easily in cold weather, and is reliable in places like Rochester and Syracuse where winter storms can knock out power for hours at a time. It is an especially good fit for homes that want the least amount of fuel maintenance.

How Propane Generators Work

Propane is a great option for homes that want independence from utility gas lines or for rural areas where natural gas is not available. The propane tank sits outside your home and holds enough fuel to get you through an extended outage. Propane has a long shelf life and does not degrade, which gives it an advantage during long winters. Many homeowners like knowing they control their own fuel supply.

How Diesel Generators Work

Diesel generators use powerful engines designed for heavier loads. They work well for larger homes, homes with higher electrical demand, or homeowners who want long runtimes. Diesel engines tend to run efficiently under heavy loads and are known for durability. They do require proper fuel storage and occasional checks to make sure the fuel stays clean.

Do Different Fuel Types Affect Generator Performance in New York

Yes, fuel type affects several things such as efficiency, run time, and long-term upkeep.

Natural Gas

• Steady supply that never needs refilling
• Clean burning
• Good for most average home loads

Propane

• Stored onsite for full control
• Long shelf life
• Clean and reliable for cold weather starts

Diesel

• Strong performance under heavy load
• Efficient for larger systems
• Requires occasional fuel conditioning

The differences are not about which fuel is “best,” but rather which one fits the way your home uses power.

How to Choose the Best Fuel Type for Your New York Home

A few simple questions can help you narrow it down.

• Do you already have natural gas service
• Do you want control over your own fuel supply
• How long do outages typically last in your area
• Does your home have a high electrical load
• Do you prefer the cleanest and simplest option
• Are you comfortable maintaining a fuel tank

Homes in cities like Rochester and Buffalo tend to choose natural gas because it is already available. Homes outside city limits often choose propane because it gives them independence. Larger properties or homes that want a heavy-duty solution might consider diesel.
