Standby power generators are beneficial to have in commercial places and homes incased of emergency power breakout occurs. There are generators that work on gas, diesel and some which are of new technology works on solar power and some are hybrid powered which runs on car batteries.

There are commercial places such as offices, hospitals, hotels and other places which are commercially being used require running on generators because they either choose to only supply electricity to their premises through generators as this source of electricity is reliable and can be cheaper too.

If you see that in modern countries such as USA, UK and Canada where there is hardly any problem of electricity load shedding but still there are places where standby power generators are being used. The reason is because the normal rate of electricity cost is more than that used in standby power generators or people keep these generators incase of emergency arises and there is power outbreak.

The standby power generators are available in different sizes and have different specifications. Not all generators run on the same source such as diesel or petrol while there are generators which run on natural gas even. The best generators which are more efficient and are long lasting which runs on diesel. Diesel generators are advisable to use where there is heavy load to cater and diesel generators are less likely to get damaged rather than generators which run on natural gas.

Standby power generators are available and manufactured in different sizes starting from small generators which run on petrol or natural gas. Small generators are useful for domestic purposes and can be kept at home. Small generators usually varying from 2Kv to 5Kv can easily carry the load of lights and fans in your home and you can even switch on your television set.

There are generators which are more than 50Kv and go along to 1000Kv. These power generators are huge in sizes and can carry the load of different things such as it can run everything in a house such as television, refrigerators, air conditioners and anything which you can think of to switch on.

Most of these heavy generators run on diesel and petrol because these two resources are the best resource to use and they can produce enough energy that the generators can produce sufficient electricity.

There is an option of keeping the generators to start automatically when there is a break in the continuity of electricity. This option helps a lot because whenever the electricity is suspended you do not need to get up from your place and go on to switch on the generator. Nowadays there are generators which are manufactured which automatically have the option to be set on auto switch on mode.

Standby power generators have huge demand and are being extensively used in third world countries because these countries do not have proper electricity infrastructure and the government has to be hooked on load shedding to provide decent supply of electricity.
