The State Group was awarded a contract from Ontario Power Generation Central Plant Group, at the Ragged Rapids Generating Station for the Electrical, Control and Protection upgrades.

  • Location:Bala, ON
  • Trades:Electrical
  • Date:September 2014

Scope of work and outcome

Our team replaced a 6.6kV metal switchgear with new arc resistant gear to meet current safety standards. We were also tasked with the replacement of the generator output cable, installation of a new protection and control system and a new Kaplan hydraulic unit for the control of the actuator system.

This project was successfully completed ahead of schedule, with a duration of approximately 12 weeks, allowing OPG to commence the necessary commissioning.
