About transmission rates

Customers with transmission accounts use large amounts of energy and invest in electrical infrastructure that allows them to receive service at high voltage (60kV or higher).

The Electric Tariff contains the approved terms and conditions of distribution voltage service provided by BC Hydro as well as the approved rates for service at distribution voltage and transmission voltage.
