If you live in an area with retail energy providers (REPs), you may choose to switch from your standard electricity utility to a REP. There are two main options for REP contracts: fixed and variable rates. If you choose a fixed-rate plan, you’ll pay a fixed price per kWh that will remain throughout the duration of your contract. On the other hand, if you choose a variable rate plan, the rate you pay for energy will fluctuate based on the wholesale price of electricity from your energy company, which represents how much power plants charge electric companies to buy the electricity they produce.
