Market & tariff

Choose your label market and enter the electricity price from your bill.

For example, 20 cents/kWh is 0.20 USD/kWh. Use your own bill rate.

Read United States guidance

Changing market selects a currency and clears the draft price for you to enter. Currency changes do not convert prices. Your remembered market sets the label reader's starting market; shared examples keep their own inputs. Separate scenario rates stay as entered.

Clearing removes saved market, tariff, scenarios and measurement observations. Export journal records you want to keep first. Analytics choices are managed separately in the footer.
