OPG cites strong quarter by Darlington, Pickering nuclear plants

Ontario Power Generation (OPG) recently released a report indicating that its Darlington and Pickering nuclear plants ran well during the third quarter and together met 38% of Ontario’s electricity needs.

OPG no longer has any active coal-burning units.

OPG’s nuclear electricity generation for the third quarter of 2014 totaled 12.8 terawatt hours (TWh) compared to 11.6 TWh in 2013 in the same quarter. In Q3, Darlington Nuclear produced 7.45 TWh of electricity, meeting 22% of Ontario’s electricity needs.

In Q3, Pickering Nuclear produced 5.35 TWh of electricity, meeting 16% of Ontario’s electricity needs, OPG said.

Compared to Q3 in 2013, Darlington’s unit capability factor for Q3 2014 was higher (90.67%) primarily as a result of a decrease in the number of days the station was shut down for maintenance outages.

Compared to Q3 in 2013, Pickering’s unit capability factor for Q3 2014 was higher (74.68%) primarily as a result of a decrease in the number of days the station was shut down for maintenance outages.

During Q3 2014, Darlington Nuclear recorded one Category C spill to the environment that was reportable to a government agency, bringing the year-to-date total to two spills.

Pickering Nuclear, meanwhile, recorded two Category C spills to the environment that were reportable to government. That brings the year-to-date total to four spills.

OPG is currently in the definition phase of the multi-billion-dollar Darlington refurbishment project.

Darlington has four nuclear units in Greater Toronto. The station is listed with a total operating capacity of roughly 3,500 MW, according to GenerationHub data. Pickering is listed with six operating nuclear units (and two out of service). The Pickering station in Pickering, Ontario is listed with an operating capacity of roughly 4,300 MW.
