You’ll need a copy of your power bill handy.

This is so you can enter your information following the easy step-by-step process.

You must use the information from your most recent power bill as the calculator adjusts based on the current season (e.g. summer, autumn, winter, spring). The bill must also include lines charges, not just power.

The estimated value of lines charges is based on the information you enter, along with TLC’s price list and price category information recorded for your connection.
