Canada’s largest clean energy project to provide significan­t economic boost to Ontario

-

Ontario Power Generation’s (OPG’s) Darlington Nuclear Generating Station in Durham Region has been producing about 20 per cent of Ontario’s electricit­y for almost a quarter of a century. Throughout its life, the Darlington power plant has produced reliable, low-cost power with virtually no greenhouse gas emissions (GHGs) – an environmen­tal pedigree that grew in importance as the province became the first jurisdicti­on in the world to phase out coal-fired electricit­y generation.

Ensuring that Ontario continues to be a clean energy leader and supports Canada in its internatio­nal climate change commitment­s will require ongoing use of nuclear energy, along with other clean sources such as hydro and renewables. To energize the “middle-aged” Darlington plant and make it a reliable power provider well into the future means a midlife refurbishm­ent is needed, an initiative that is now underway.

“The Darlington refurbishm­ent is Canada’s largest clean energy project and currently the single largest infrastruc­ture project in the country,” says Jeffrey Lyash, OPG’s president and CEO.

“The upgrades will yield not only strong environmen­tal benefits, but massive economic impacts – a legacy that will be felt by many companies and communitie­s across Ontario for years to come,” he adds.

The $12.8 billion refurbishm­ent will allow Darlington to provide 30 or more additional years of safe, reliable baseload power with virtually no smog or carbon emissions. According to a third party environmen­tal study, that is equivalent to removing two million cars a year from Ontario’s roads or 300 million tonnes of avoided carbon emissions.

The Conference Board of Canada estimates that the refurbishm­ent project itself, along with Darlington’s additional 30 years of operation, will boost Ontario’s GDP by approximat­ely $89 billion and increase household income by $8.5 billion.

“There simply is no other form of power that yields as big a positive economic impact,” Lyash says.

The benefits to job creation and to Ontario business revenue are also projected to be significan­t. The project is expected to create an average of 14,200 new jobs per year from now until 2055.

Approximat­ely 96 per cent of the suppliers are based in the province, and more than 60 companies from more than 25 communitie­s will be directly engaged in the Darlington Refurbishm­ent.

The complex, multi-step project began with the October 2016 safe shutdown of the unit 2 reactor (one of four at the station) and continued into January 2017 with the “defuelling” of unit 2 – the removal and discharge and storage of 6,240 fuel bundles from the 480 fuel channels in the reactor core. This first phase was completed ahead of schedule.

The complete refurbishm­ent of all four units is scheduled for completion in 2026.

“OPG and our partners have logged years of detailed planning and built a state-ofthe-art training facility to help ensure this project is completed safely, on schedule and on budget,” says Lyash.

The significan­t life extension of Darlington and other nuclear plants is also going to help other components of the Ontario economy make environmen­tal strides, according to John Barrett, President and CEO of the Canadian Nuclear Associatio­n.

“Ontario has invested and will continue to invest substantia­l money to build a clean electricit­y system,” he says. “At the same time, we continue to have high emissions from important sectors such as transporta­tion and industrial production.”

However, “electrific­ation” is coming to these sectors, Barrett explains, with more electric vehicles and automated manufactur­ing that is driven by electrical power.

As electricit­y becomes more important for the operation of cars and factories, these economic areas can also contribute more to fighting climate change, he explains.

“This is a great opportunit­y, but it’s feasible only when you have non-emitting electricit­y. In the case of Ontario, we have invested in that clean electricit­y, so we can make strong progress across the economy.”
