Fixed-Rate Plans: These plans are steady and predictable; the price per kWh you sign up for will remain that same for the entirety of your contract. (The only changes in your bill will be from forces outside of your REP's control, like changes in TDU fees, or changes in federal, state, or local laws.) Often fixed-rate plans will have a slightly higher price per kWh than others, but you're paying for the predictability. They're great if you live by your budget – and even greater if you happen to sign up when rates are low.
