Sunnybrook Health Science Centre- High Voltage Emergency Power Renewal, Toronto

The $15.4 Million power upgrade was completed in February 2016. It encompassed a complete renewal of the facilities’ high voltage emergency power system. The project required two phases to insure the Hospital had sufficient emergency power during the construction process. The first phase entailed providing two (2), 2MW, 4160diesel generators, (1) 600V, 750kW diesel generator, 4160 switchgear, paralleling and synchronization controls, an automatic transfer system (capable of closed-transition transfers, not exceeding 100ms) and a PLC based load management system. The second phase of the project involved providing two (2), 2MW, 4160 diesel generators, paralleling and synchronized controls, an automatic transfer system (capable of closed-transition transfers, not exceeding 100ms) and additional load management system upgrades.

To accommodate the new generators, the project required the construction of an air intake plenum, exhaust plenum and modifications to the building’s structural steel. It also included modifications to the existing fuel oil systems, ventilation systems and addition of a diesel emissions reduction system complete with onsite urea storage.

The upgrade left the hospital with a new system, greater capacity and flexibility, the ability to make closed-transition transfers with the utility and the ability to operate their generators for demand response.
