Transmission vs Distribution

  • Transmission

    High-voltage lines move bulk power across the province. In Alberta, transmission facilities are typically defined as 69 kilovolts or higher.

  • Distribution

    Low-voltage lines carry power from the transmission system to your home, farm or business. The voltage is lowered to travel safely through towns, cities and rural areas.
