How much will an equivalent power grid electricity supply cost? 

You probably have an idea of how much the cost of electricity from the national grid costs when you pay your monthly bills. One recent statistic on the average cost of electricity nationwide indicates that the average monthly bill for an average home is $111.67 which means an average of $3.72 per day. 

Which option is better between the National grid and generator? 

It shouldn’t take long for you to figure out the more expensive option between the national grid electricity and the use of a generator. Generally, getting your electricity supply is more convenient, in addition to the lower price. Getting your electricity from the grid is more practical and more environmentally friendly than running a gas-powered generator. 

Though the use of a generator may be costlier than electricity from the national grid you will need a generator in case of a power outage caused by natural disasters. For this reason, your investment in a generator is worth the trouble.  If you are unsure of the type of generator to choose to compliment power from the national grid, please contact us at Mr. Electric Of Katy.
