A few things to remember

  • Don’t forget to read your plan’s Electricity Facts Label before signing up. It contains important information including:
    • Price per kilowatt-hour based on usage
    • % renewable energy sourcing
    • Early termination fees
  • Enjoy hassle-free supplier setup. Once your order has been confirmed, your new supplier will set up service with your utility, or transmission and distribution service provider (TDSP) – but don’t worry, there shouldn’t be any interruption to your power during the switch.
  • Understanding your electricity bill. Your local TDSP will still deliver your electricity and maintain electric infrastructure including meters and power lines. Your utility fees can be found as TDU or TDSP charges on your monthly bill. They are independent of your supplier rate.
