As of April 1, 1999, transmission and distribution wire operations became regulated by the Ontario Energy Board (OEB) under the Ontario Energy Board Act, 1998.

As the successor company responsible for the former Ontario Hydro transmission and distribution wires facilities, the mandate of Hydro One Networks Inc. is to operate, maintain and administer its transmission and distribution facilities in a safe and reliable manner, to continuously improve operating efficiencies and to facilitate access to the electricity supply marketplace in the province.

Information on the company's various regulated activities can be found here, including rate order applications and other submissions to the OEB, transmission and distribution rate schedules, stakeholder consultation activities, and other related information.

Hydro One Networks' current Conditions of Service, as filed with the Ontario Energy Board, is effective August 1, 2004 and available online for review or download.
