Darlington refurbishment project passes midway point

In 2016, after years of detailed planning and preparation, OPG’s team of project partners, industry experts, energy professionals, and skilled tradespeople successfully shut down the first of four Darlington reactors scheduled for refurbishment over the subsequent 10 years.

Today, the Darlington refurbishment project continues to track for completion by the end of 2026. This is due to the dedicated support of OPG’s skilled workforce, Ontario’s robust nuclear supply chain and other project partners, suppliers and contractors.

Recently, the project passed the midway point of the 10-year execution of this $12.8 billion project when Unit 1 was taken off the grid to begin its scheduled refurbishment. This will enable production of clean, safe, low cost and emission free electricity from Darlington for an additional 30-plus years.

As of Dec. 31, 2021:

Safety
  • By the end of Q4 of 2021, our Total Recordable Injury Frequency was trending below target at 0.25 versus our annual target of 0.40.

Cost
  • The four-unit project continues to track on budget.

Schedule
  • The four-unit Darlington Refurbishment has maintained the forecasted dated for completion in 2026.

Quality
  • No loss of generation or impacts to the schedule due to quality related issues.
  • Quality of work to date has surpassed industry standards and, in most cases, is industry-leading.

Environment
  • The project continues to operate well below all regulatory environmental limits.
  • No reportable spills, infractions, or station effluent exceeding regulatory limits.
