Ontario Power Generation (OPG) plays a major role in helping Canada achieve its commitments under the Paris climate agreement. OPG’s nuclear fleet is a key contributor to the generation of electricity that is virtually free of greenhouse emissions. Not only OPG, but the entire industry globally is now required to optimize the power generated by existing plants by increasing the efficiency of equipment and by chasing "lost megawatts"". As a result, there has been a tremendous increase in technologies that are designed to improve communications, sensors, analytics, interconnectivity and data visualization. This has paved the way for accurate equipment health monitoring in ways that were not possible before. The power industry has an opportunity to leverage these new technologies to advance their condition monitoring programs and improve equipment reliability. These opportunities include the ability to continuously monitor and diagnose power plant assets by providing quick and effective identification of deteriorating equipment conditions and troubleshooting the cause of these conditions. This is referred to as Condition Based Monitoring (CBM). To achieve this, Ontario Power Generation (OPG) will be establishing a fleet-wide CBM in the next few years which will greatly reduce the Operations & Maintenance (O&M;) costs. This involves a high performance diagnostic tool that can combine the power of on-line process data acquisition with advanced diagnostics methodologies. The tool will use analytical models based on thermodynamic principles combined with the knowledge of component diagnostic experts. CBM will reduce costly and error prone reoccurring maintenance and disassembling inspection activities. The Federal climate change strategy highlights nuclear generation’s continued role in helping Canada meet its targets. In addition to reliable base-load generation, customers will also benefit from the long-term, lower and stable electricity prices offered by nuclear power. OPG is well positioned to provide the province with the clean, safe, reliable and cost-effective electricity it needs today, and to support its future electrification plans."
