A GUIDE TO USAGE CHARGES
Your energy usage charges are easy to understand once you find out what all the terms and measurements mean. Here is a summary of the most common energy usage charges, so how they are calculated.
ELECTRICITY USAGE CHARGES
Retailers express electricity as energy consumed over time. The more energy you consume, the higher the bill. This is called the “variable” or “consumption” charge. The unit your electric retailer uses is kilowatt hours (kWh). Typically, your bill will show:
c/kWh (cents per kilowatt hour.)
This c/kWh charge may vary if you have a different peak, off-peak, or shouldered charges. Pricing structures include a flat fee, controlled load (dedicated appliances with own meter), credits for feed-in solar power, or different discounted blocks.
Your retailer estimates your charges or reads from your meter. This is indicated “E” for estimated or “A” for actual.

Your retailer will also typically charge a supply charge, fixed charge, or service charge, which is a fixed rate that includes network maintenance, administration, and other delivery costs. It’s usually expressed in cents per day.
OTHER FEES
Retailers may charge additional fees such as an early termination fee, late payment/overdue fee, establishment fee (for new customers) or a payment processing fee for credit cards and These will be explained on your bill.
