Hydro One Networks Inc. has awarded ABB a major order to supply an indoor gas-insulated switchgear substation, an outdoor switchyard with air-insulated switchgear and associated transmission infrastructure. The new substations will replace an existing installation built in the 1950s and will serve Canada's largest city, Toronto.

ABB's scope of supply includes 115-kV gas-insulated and air-insulated switchgear, surge arresters, transformers and cables. As part of the turnkey contract, ABB is responsible for the system studies, design, engineering, supply and installation of the substations, including civil works. The project is scheduled for completion by 2013.

Hydro One Networks owns and operates 96% of Ontario's transmission network. The network has 280 transmission substations, a distribution system spanning around 75% of the province, with 1,010 distribution substations and 26 facilities that interconnect the transmission grid with neighboring provinces to enable power trading.
