Predix Asset Performance Management


Bruce Power operates the world’s largest nuclear generating facility and provides Ontario, Canada with roughly 30% of its electricity. The company’s site in Tiverton, Ontario is home to eight CANDU reactors—each capable of producing up to 800 megawatts. 



With the nuclear power industry struggling to balance rapidly increasing demand with the costs and safety measures required to support an aging equipment base, Bruce Power identified scheduled maintenance activities as a source for efficiency gains—enabling increased availability. Specifically, the company had more scheduled maintenance activities than capacity, resulting in delays.  



Bruce Power was able to identify and implement, on a continuous basis, maintenance-related work-process improvements through Predix Asset Performance Management (Predix APM) (formerly Meridium Enterprise APM) to increase availability while continuing to meet the company’s high safety standards. Using Predix APM, Bruce Power utilized a risk-based approach to determine optimal maintenance intervals for its assets.


By implementing Predix APM, Bruce Power was able to integrate:


  • Historical asset health data (mean time between failure, Pareto, and failure analyses)
  • Maintenance performance data (inspection, calibration, test results)
  • Current asset health data (operator rounds, condition-based monitoring)


The company was also able to identify maintenance inefficiencies and readjust its maintenance strategy based on efficiency gains, reducing costs.



Bruce Power found that by continually identifying opportunities for maintenance-related work-process improvements with Predix APM, it was able to:


  • Increase the life of existing assets
  • Improve plant reliability and availability
  • Increase the amount of power pumped into the grid


In 2014, Bruce Power invested over $200 million of private dollars into publicly owned reactors during three planned maintenance outages. These maintenance investment programs helped increase reliability and extend the life of its units, which provide over 30% of Ontario’s power at 30% below the average price of electricity. And as a result of one of its units surpassing 500 days of continuous operation—and providing over 15% of Ontario’s electricity—Bruce Power was recognized as the top performing multi-unit CANDU plant in the world by the Institute of Nuclear Power Operators.
