Your Campbell electricity rate will depend on the type of plan that you choose. If you choose a fixed-rate plan, your rate will stay the same for the length of your contract. However, if you choose a variable-rate or time-of-use plan, your rate could change each month depending on market conditions.
It's important to keep in mind that market conditions can change at any time, so it's always a good idea to monitor your usage and make sure you're not using more electricity than you can afford.
