OPG Continues Overhaul to Produce Clean, Reliable Power in CornwallDecember 19, 2022
Cornwall Ontario – Ontario Power Generation continues to make significant investment in Cornwall to ensure it will continue to produce clean, reliable, low-cost power for Ontario, and over the past several months that has added up to tens of millions of dollars.
Significant work continued throughout 2022 as a total of 15 projects were in the design, planning or execution phase during the year. Some of the larger ongoing projects included:
- the continuation of the transformer overhaul program with 8 of 13 now completed
- generator exciter replacements continue with 11 of 16 now completed
- continuation of significant site concrete mitigation projects
- successful replacement of two overhead bridge cranes in the work maintenance bay
- completed construction of one of three new ice sluice plugs
- continuation of phase-two of a landscape design at the Saunders Hydro Dam Visitor Centre
- completion of the North Channel worksite upgrades to support the ice boom program work including new boom cables
- completion of battery bank and direct current equipment replacement
- hatch cover generating unit access controls for all 16 units completed
- headgate wire rope replacement
- ongoing renovations for 2nd and 3rd floor administrative buildings to support overhaul program and ongoing ops
“We are relied upon each and every day at R.H. Saunders GS to provide a significant amount of clean, renewable, electricity for Ontarians,” said Peter Forrester, Electrical Trades Management Supervisor at R.H. Saunders GS. “It takes a tremendous amount of teamwork to safely plan, coordinate, and execute the major outage work.”
Project work continued to ramp up significantly as the station continues to prepare for a significant generator overhaul and runner replacement program that is now scheduled to begin in January, 2023 and will last well over a decade. Many of the projects this year were completed in anticipation of this major overhaul program. The program is also part of OPG’s commitment to reinvest in its hydro fleet over the next twenty years and contributes to the company’s overall climate change goal of becoming a net-zero carbon emissions generator by 2040.
In 2022, OPG’s RH Saunders GS hired 10 permanent maintenance staff, and 22 additional long-term temporary trades staff to support ongoing projects and maintenance. Some of these temporary staff are local, providing good jobs to residents of Cornwall. Some are from outside the area, who now rent, shop, and support the local economy in many ways. In total, over 80 full-time staff and around 100 contractors are working at the RH Saunders GS site.
OPG also opened the Saunders Hydro Dam Visitor Centre once again in June. Over 6,000 people visited the centre as tourists, event participants, schools, and community groups that book the centre for meeting space.
