Zerem is currently doing the civil, mechanical, and electrical work for the Ontario Line’s main step-up substation.
This substation will be located east of Exhibition Station and serve as the key powerhouse that will help keep trains running every day. The facility will take electricity from Toronto Hydro, convert it into high-power energy and send it directly to the tracks and southern stations.
In the event of a power failure at the operations, maintenance and storage facility (OMSF) in the north, the Exhibition substation is capable of feeding power to the entire subway line.
