Some guy knocked on my door telling me all the money I could save if I switched to the electricity company he was selling. I have heard it all before. So much that I looked into it for myself when I went to visit site online that had the details. When you talk to those people knocking on your door who want you to switch right there, you can miss the details in the fine print. Can you save money on your electric bill by switching? Yes. However, you need to be with the right company.
You need to first look at your usage. Some companies have a minimum amount of kilowatt hours you must use each month or pay more on your bill. Some contracts with power companies are fixed rate, and some are variable rate. The variable rate can suddenly change. It is better, in my opinion, to go with a low fixed rate per kilowatt hour. Also, you should see how long the contract is for and what happens if you do not cancel when it comes time for renewal. It is not anything awful, you just want to review before getting locked in for another term.
Be sure to read the fine print to find any hidden fees. There is nothing you can do about the taxes and government imposed surcharges. You will pay those no matter who you go with. What you are looking for is the lowest rate per kilowatt hour that you can get without any minimum usages you cannot live with. If you use a lot of electricity every single month, you can look for a low rate that does have a minimum usage requirement that is not over what you always use no matter what month it is. You can save money on your electric bill, but you want a good contract to do it.
