New 735/315-kV Section, Compensation and Line Reorganization at Bout-de-l'Île Substation

To meet increasing demand and ensure the long-term operability of facilities in the northeastern part of the metropolitan Montréal region, Hydro-Québec has prepared a plan that groups together several projects in the east end of the island of Montréal, including the addition of equipment to Bout-de-l'Île substation.

Located in the borough of Rivière-des-Prairies–Pointe-aux-Trembles, Bout-de-l'Île substation is bordered by Highway 40 to the southwest, Avenue Armand-Chaput to the west and Boulevard Maurice-Duplessis to the north. From this strategic location, it supplies all of the substations in the east end of the island of Montréal with the power needed for the distribution system. In addition to being a source substation, it also delivers power to a large number of customers in the borough.

To meet current needs while providing for future flexibility, Hydro-Québec must substantially increase the capacity of this substation, which was commissioned in 1956. To do so, aging equipment will be replaced with new, higher-capacity models and new equipment will be added. In addition, Bout-de-l'Île substation will be connected to the nearby 735-kV line that supplies Duvernay and Boucherville substations.

Once commissioned, the new equipment will enable Hydro-Québec to adequately meet the electricity needs of the area for many years to come.
