Ontario Commits to Future in Nuclear Energy

December 3, 2015

News release from the Ministry of Energy

Ontario has updated its contract with Bruce Power and will proceed with the refurbishment of six nuclear units at the Tiverton-based nuclear generation station.

Nuclear refurbishment will boost economic activity across Ontario, create jobs, ensure savings for ratepayers and secure a clean supply of reliable electricity. The Bruce Power refurbishment project will make up to 23,000 jobs possible and generate about $6.3 billion in annual economic benefits in communities throughout the province. Ontario is home to a globally recognized CANDU nuclear supply chain with more than 180 companies employing thousands of highly skilled workers. 

The government was further able to optimize the nuclear refurbishment schedule in order to maximize the value of existing nuclear units. The revised timeline will mean construction commences in 2020, rather than the previously estimated start date of 2016. 

Accordingly, the updated agreement has achieved $1.7 billion in savings for electricity customers when compared to the forecast in the 2013 Long-Term Energy Plan (2013 LTEP).  This means a reduction in forecast household electricity bills by about $66 each year over the next decade. The contract also protects the interests of electricity consumers by ensuring Bruce Power assumes full risk for any potential cost overruns or delays.

Key aspects of the updated agreement include:

  • Securing 6,300 MW of emissions-free, baseload generating capacity while deferring major project work to 2020, to maximize value of the units
  • Bruce Power would invest approximately $13 billion of its own funds and agrees to take full risk of cost overruns on refurbishments of the six nuclear units
  • Initial price for Bruce Power's generation set at $65.73/MWh starting January 1, 2016. The average price over the life of the contract is estimated to be $77/MWh, or 7.7 cents per kilowatt hour (kWh).
  • Both prices are within the range assumed in the 2013 LTEP for refurbished nuclear energy and are lower than the average price of electricity generation in Ontario, which in 2015 was $83/MWh
  • Definitive contract off-ramps that allow the government to assess Bruce Power's cost estimates for each reactor prior to its refurbishment and stop the refurbishment if the estimated cost exceeds a pre-defined amount

The province is achieving balance by contracting affordable, stable and reliable generation for residents and businesses while securing investments that will be a key source of local job creation and economic growth.

Securing clean, reliable baseload power for decades to come is part of the government's plan to build Ontario up. The four-part plan is includes investing in people's talents and skills, making the largest investment in public infrastructure in Ontario's history, creating a dynamic, innovative environment where business thrives and building a secure retirement savings plan.


"This agreement makes 23,000 jobs possible and supports an estimated $6.3 billion in annual, local economic development. Our updated agreement with Bruce Power secures 6,300 MW of emission-free, low-cost electricity supply. These actions will save the electricity system $1.7 billion and provide important relief for electricity consumers." 
— Bob Chiarelli, Minister of Energy

""Today is a major milestone in the history of Bruce Power as we build on our existing agreement with the province and extensive experience to enter the next phase of our site development. This provides us the opportunity to secure our long-term role as a supplier of low-cost electricity by demonstrating we can successfully deliver this program incrementally."
— Duncan Hawthorne, President and CEO, Bruce Power

Quick Facts

Following the release of the 2013 LTEP, the amended BPRIA was negotiated over two years by the Independent Electricity System Operator (IESO).

The Bruce nuclear site is the world's largest operating nuclear facility. Since it was formed in 2001, Bruce Power and its industry partners have engineered and developed first-of-a-kind technologies that helped return four dormant nuclear units to service.

Nuclear energy plays a fundamental role in Ontario's electricity system. It provides over half of Ontario's annual generation, meeting most of Ontario's baseload requirements.
