Generator Installation
When a nor'easter or a summer storm takes the power down, a standby generator keeps your home running. Williams Energy handles generator installation across the South Shore, and as a propane supplier, we keep it fueled too.
Williams Energy provides whole-house generator installation across the South Shore, so a power outage does not leave your family in the cold and dark. The weather here is unpredictable, summer thunderstorms and winter nor'easters both knock out the grid, and a standby generator in our service area keeps the essentials running until the power comes back.
What a Standby Generator Keeps Running
A whole-house generator does more than keep the lights on. Sized to your home, it powers the things you actually depend on during an outage.
Heat & HVAC
Refrigerator & Freezer
Sump Pump
Well Pump
Lights & Outlets
Internet & Remote Work
Medical Equipment
Security & Doors
Standby or Portable?
Both are called generators, but they do very different jobs. For real whole-home backup, a standby unit is the one worth installing.
Standby Generator
Permanently installed outside the home and wired in through an automatic transfer switch. It senses an outage and starts on its own within seconds, powers the whole house, runs on propane or natural gas, and needs no cords or refueling. You can be away and it still works.
Portable Generator
Lower up-front cost, but it has to be rolled out, started, and connected by hand every time. It powers only a few things through cords, runs on gasoline that needs constant refilling, and must stay outside and well away from the house for safety.
We Install It, and We Fuel It
This is where Williams Energy is different from an electrician who only does the wiring. A standby generator needs a steady fuel supply, and most run on propane. We are a propane supplier, so a propane generator can run off a tank we install and keep filled, or tie into the propane you already have.
That means one company for the whole thing: the team that installs the generator and the transfer switch is the same name that handles propane delivery and your tank and monitor. When the power goes out, you are not wondering whether the generator has fuel, because we have been keeping it filled all along.
How Generator Installation Works
Sizing matters more than anything with a generator. Too small and it cannot carry the house; oversized and you have paid for power you never use. Here is how we get it right.
Size it to your home
We assess what you want to keep running and size the generator and transfer switch with a load calculation, so it matches your home instead of a guess.
Plan fuel and permits
We plan the propane or gas hookup, set the tank if you need one, and pull the permits the installation requires.
Install and connect
Our licensed electricians set the generator, wire the automatic transfer switch into your panel, and connect the fuel supply.
Test and hand off
We start it up, test that it takes over automatically when the power drops, and walk you through how it runs and how to keep it ready.
Why Neighbors Choose Williams for Generators
A standby generator is only worth installing if it actually starts when you need it, which is why fuel and follow-through matter as much as the install. With Williams Energy, the company that wires it in is the company that keeps it fueled and can service it down the road, all under a name the South Shore has trusted since 1919. While the electrician is out, it is also the moment to handle any other electrical installation or electrical repair on your list.

Generator Questions, Answered
What does a whole-house generator power?
Sized correctly, a standby generator can run your essentials and more: heat and the HVAC system, the refrigerator and freezer, the sump pump, the well pump, lights and outlets, internet, and medical equipment. We size it to what matters most in your home.
What is the difference between a standby and a portable generator?
A standby generator is permanently installed and starts automatically within seconds of an outage, powering the whole home with no cords or refueling. A portable costs less but must be set up by hand, run outside, refueled with gasoline, and only powers a few things. For whole-home backup, standby is the real solution.
What fuel do standby generators use?
Most run on propane or natural gas. Because Williams Energy is a propane supplier, a propane generator can run off a tank we install and keep filled, so the company that installs it also keeps it fueled.
Do you handle the fuel hookup too?
Yes. We install the generator, wire the automatic transfer switch, and handle the propane tank and supply. It is one company for the whole job, install and fuel, instead of an electrician and a separate fuel company.
How big a generator do I need?
It depends on what you want to keep running. We do a load assessment to size the generator to your home, so you are not paying for more than you need or coming up short when the power goes out.
