Understanding Electricity Plans
Fixed-rate plans: What’s fixed—and what can still change?
A fixed-rate electricity plan can make planning easier, but the word “fixed” deserves a closer look. Your monthly bill still depends on how much electricity you use, the charges in your agreement and any permitted adjustments.
Start with the Electricity Facts Label
The Electricity Facts Label (EFL) explains the plan’s pricing, term and important conditions. Read it alongside the Terms of Service. Review the energy charge, monthly fees, delivery charges and any usage-based credits. The advertised average price at one usage level is not a promise that your own average price will be identical.
Why can the total change?
A hotter month can mean more air-conditioning use. More kilowatt-hours can increase the bill even when the energy rate stays the same. Approved TDU delivery-charge changes can also affect fixed-rate plans. Other permitted adjustments may apply under the agreement.
A simple example
At a hypothetical energy-only price of 10¢ per kWh, 800 kWh costs $80 and 1,400 kWh costs $140. The price per unit stayed the same; consumption changed. Delivery charges, fees and taxes would be additional in this simplified example.
Before choosing a contract
- Compare a full year of usage, including mild-weather months.
- Check the contract length and early termination fee.
- Ask which charges can change and when the agreement expires.
- Compare estimated total bills at the same usage levels.
