Generators Help you Weather Power Outages


October 1, 2013 STORM PREPAREDNESS


No matter the season, experiencing a power outage can be a real threat to a homeowner’s peace of mind. It’s estimated that 3.5 million Americans experience power outages each week. More than 70 million people have experienced an outage that lasted more than 24 hours sometime in the last two years.

According to the Edison Electric Institute, the majority of these outages are weather- related.

The good news is, there are portable generators designed with user ease in mind that can be short-term sources of emergency power. Contained in steel frames, with wheels for easy relocation, they are powered by gasoline stored in a provided tank.

Those looking for a more permanent alternative may consider a standby generator. This is hardwired into the home’s electrical system and connected to the natural gas or propane supply. When the utility power goes out, the load center senses the loss of electrical power and turns on the generator, which then powers all of your emergency circuits. You can back up just a few rooms or the whole house. Once the utility power comes back on, the load center will automatically switch back to utility power. If you were not home when your power went out, you would not even know the difference.

Standby generators don’t require much maintenance and can sit outside next to your air-conditioner units. Stationary, outside-mounted generators run on propane or natural gas and supply more power than portable models. Determine your average wattage needs for most common electricity-using household appliances and devices to choose the best model for your needs.

HOW TO CHOOSE

Calculate the watts for the items you need. Figure on $500 to $1,000 for installing a stationary generator and, for all types, at least $500 for a power-transfer switch. A transfer switch permanently patches a backup generator into the electrical system in your home, eliminating the need to run extension cords into and out of the house. Installing a transfer switch is the only safe way to run hardwired items, such as a furnace fan and central air, and to route power to wall outlets.

Manual transfer switches require that you flip the switch and change over from standard utility power to standby power during a power outage. Automatic transfer switches kick in on their own when the power goes out — useful for running the refrigerator or keeping the furnace going when you’re away from home.

Transfer switches are included with many stationary generators. A manual switch will cost roughly $500 installed; an automatic version, about $1,000.

Other features:

Wheels — Models with these can be moved by one person, rather than two, but you’ll still need two people to lift the generator.

Oil guard — This protects the engine from damage by shutting it down if the oil level falls below the minimum.

Fuel gauge — Lets you check the level inside the tank at a glance, important for extended power outages.

Inverter technology — Improves power quality via a microprocessor-controlled circuit. Currently, however, models that offer it have low wattage and a high price.

 

Nice, but not essential:

Electric starting — Provides push-button starts via a battery-powered motor, saving you the hassle of pull-starting.

Alternative-fuel capability — Lets you run the generator on propane or natural gas, as well as gasoline.
