Aimed at extending the life of the Darlington Nuclear Power Plant by 30 years, this $12.8 billion megaproject included extensive re-tubing and feeder replacement, rehabilitation of the turbine generators and control systems, defueling of the reactors, and refurbishment of fuel-handling equipment.

The overall mega-program is considered to be “first-of-a-kind” (FOAK), with the individual projects within the mega-program also comprised of FOAK and first-in-a-while (FIAW) elements.

Pegasus-Global was appointed as an independent auditor and assessor of the refurbishment megaproject, providing an objective assessment of the degree to which OPG’s plan and execution were consistent with the way other megaprojects have been delivered. This evaluation included a review of processes for the management of costs and schedule, program controls, and the application of contingency. It culminated in Pegasus-Global providing testimony before the Ontario Energy Board.
