Generator Costs And Yearly Maintenance Requirements

Standby Generators

A standby generator is usually and permanently installed outside your residence or commercial building and wired directly into your electrical system. It is used to provide power to some or all of your circuits during a disruption of utility power. Standby generators can be fueled by liquid propane, natural gas or diesel and usually start effortlessly and automatically. 

A standby generator may cost as little as $2,900 or as much as $15,000 or more--the greater the power capacity, the higher the cost. Additional installation costs also apply to your specific system. Standby generators create from 7,000 to 25,000 watts or more of power. You'll have to choose a standby generator that supplies sufficient peak and continuous wattage for the circuits or appliances you need to power.

Portable Generators

Portable power generators are versatile and used for:
• emergency power at home 
• power in remote locations where utility power is unavailable or
• recreational purposes, like boating or camping

Portables can be fueled by gasoline, liquid propane or diesel and include 120-volt power outlets like the ones in the walls of your home. When the generator is running, you can plug appliances and tools directly into these outlets. Some generators also include 240-volt outlets (that is, the kind of outlet for an electric dryer or for other large appliances). 

Portable power systems can range from  $1,500 to $3,900 depending on wattage and require manual starting. Manual transfer switches can also give you the ability to connect a portable generator to your permanent electrical system. You can choose the circuits or equipment that you need to power based on the generator's capacity.

What is the best generator for the money? The installation costs of portable generators are usually less than that of standby. Factors such as manual activation and fueling are required to keep the portable system functioning during an emergency/outage.
