Back up power generation
Don’t leave yourself in the dark

Power outages and bad weather go hand in hand. And they’re happening more frequently. Losing power in your home for just a few hours can mean freezer loads of spoiled food and family discomfort.

Losing power for just a few hours at your business could mean lost revenue in the thousands of dollars. When the lights go out is when the losses mount. And that’s when you’ll be rewarded for planning ahead by installing back up power generation from Granahan Electrical Contractors.

Whether your home needs just a 6 kilowatt emergency generator or your business needs 1000, get a standby generator that’s right sized for you.
