DARLINGTON REFURBISHMENT PROJECT
FINISHED AHEAD OF SCHEDULE
“Completing the
full Darlington
refurbishment
on-time and underbudget is a made-inCanada win for
our economy.”
THE GOVERNMENT OF ONTARIO announced the completion of construction on the refurbishment of the Darlington Unit
4 nuclear reactor. The unit is now complete and will be
returning to service four months ahead of schedule, the
overall project coming in $150 million under budget.
“Last year we returned another refurbished unit
at Darlington four months ahead of schedule, and
we’ve done it again. Completing the full Darlington
refurbishment on-time and under-budget is a made-inCanada win for our economy, generating $90 billion in
economic bene昀椀ts and supporting 14,200 good-paying
jobs,” said Stephen Lecce, Minister of Energy and
Mines.
The Darlington refurbishment project (No. 6 on
ReNew Canada’s 2026 Top100 Projects report) involved

the complete overhaul of all four nuclear reactor units,
extending the station’s operating life to at least 2055. With
all four units refurbished and ready to be brought back
online, this marks the completion of the world’s largest
refurbishment project to-date, with the Darlington Nuclear
Generating Station ready to deliver more than 3,500 MW of
clean, reliable, emission-free electricity—enough to power
3.5 million homes—for at least 30 more years.
“The skills we developed and lessons we learned during
this project are invaluable as we proceed with refurbishing
Pickering Nuclear Generating Station, continue construction
on the G7’s 昀椀rst Small Modular Reactor at the Darlington
New Nuclear Project, and study the potential for up to
10,000 MW of new nuclear at Wesleyville,” said OPG CEO
Nicolle Butcher.
