5 Overview of CEATI International Addressing Critical Needs in the Electricity Industry The electricity industry continues to undergo fundamental changes which are shaping the way engineering work is performed and energy services are provided. Low load growth, over-capacity and future market uncertainty are creating pressures on the availability of capital and the reduction of operating costs to address issues of Aging Infrastructure. As electrical utilities are looking to replace and refurbish assets, the need to perform effective condition assessment, risk management activities and strategic asset management planning arises. These concerns are amplified by an increasing Loss of Internal Technical Expertise. As senior engineers retire and new engineers are brought in, the need to retain institutional memory and provide training guidance becomes ever more critical. As electrical utilities are forced to upgrade and replace their aging infrastructure, many experience challenges in keeping on top of the flood of Emerging Technologies entering the market. It is both time consuming and capital intensive to find, test, and evaluate these technologies. Therefore, choosing the wrong one can lead to performance and financial consequences down the road. Finally, considering high energy demands, along with increasing pressure to reduce greenhouse gas emissions and mitigate the effects of extreme weather events, the electric utility sector is faced with the unique challenge of providing energy services which are both Cleaner and More Reliable. Advancements in sustainability for all will require innovative approaches and rethinking business as usual. Through its networking platform, collaborative projects, library of technical reports and training opportunities, CEATI International assists organizations in addressing today s most pressing issues while building more resilient systems for the future. The CEATI Program Model The CEATI Program Model provides electrical utilities with a cost-effective vehicle for sharing experiences and addressing issues pertinent to their day-to-day operations, maintenance and planning.

18 Thermal Generation Today's competitive energy market and environmental concerns require operators to improve efficiency, reduce greenhouse gas emissions and maximize the useful life of their conventional thermal power plants, while minimizing both operating costs and capital investments. CEATI s Thermal Generation Interest Group (TGIG) works to identify immediate design, operational, and maintenance issues while staying on top of emerging thermal technologies. Impacts of Cyclic Operation on Maintenance Programs Many utilities are being forced to operate previously base-loaded units in a cyclic mode due to displacement from the increasing prevalence of non-dispatchable power from alternative energy sources, as well as other economic pressures. The cyclic operation mode poses new and different damage mechanisms and can also accelerate current damage processes in major components. Cyclic operation can have a significant impact on the reliability and life of many components which were designed for base load operation. Thus, plants that have undergone changes in operating mode from base load to cycling need assistance in updating and modifying their existing maintenance program to help guarantee significant savings, increase operational flexibility & response, and improve profitability. TGIG developed the Impacts of Cyclic Operation on Maintenance Programs study to provide specific information on ways to update maintenance programs, address the consequences of cyclic operation on plant equipment performance and asset management. Plant owners and operators will also benefit from this project as it will include state-of-the-art developments in the field Portfolio Highlights Guidelines for the Re-Commissioning of Coal-Fired Power Plants On-Line Monitoring and Evaluation of Critical Components Generator Maintenance and Condition Assessment Guide Environmental Controls Working Group Impacts of Fast and Flexible Generation Working Group Reliability and Performance Issues with Combustion Turbines Impacts of Cyclic Operation on Maintenance Programs 2015 Executive Committee TGIG Chair: Dale Bradshaw, NRECA TGIG Vice-Chairs: Doug Campbell, Nova Scotia Power Joe Siracusa, Ontario Power Generation G-10 CEATI 2015 / 2016 Topics & Issues at a Glance Reliability Improvement Greenhouse Gas Mitigation & Effective Pollution Control Strategies Operations Maintenance Improvements Efficiency Enhancement Training, Personnel Practices and Safety Future Developments for Continued Operation of Coal-Fired Plants Technical Advisor Duncan Sidey Mr. Sidey has over 30 years of experience in the power generation industry, including 25 years of involvement working for Ontario Hydro/Ontario Power Generation.

The objective of the working group is to allow members to interact effectively to exchange information to improve the overall performance of fast and flexible response equipment through: discussion of operating experiences, including performance, reliabilities and availability; discussion of maintenance programs, including repair techniques; discussion of success or otherwise of design changes; identification of areas for improvement and initiation of projects to address them. On-Line Monitoring and Evaluation of Critical Components Reliability, availability and performance efficiency of operation are critical to the successful management of power plants. Good operating and maintenance practices are essential to minimize forced or unforeseen outages and ensure efficient operation. A good understanding of the condition of critical equipment allows focused maintenance plans to be developed in a timely manner so that appropriate action can be taken under planned outage periods. Significant advances have been made in the past 10 years or so in the development of physical tools to monitor the condition or health of components, both during on-line operation and during outage inspections. More importantly, major advances have been made in analytical tools to interpret the gathered data in real time. These tools are used to identify issues at early stages of development, such as the deterioration of equipment efficiency, and also to track the development of faults prior to any failure. This means that actions can be planned and carried out to ensure proper maintenance and continued performance, related to unwanted failures and associated forced outages. TGIG developed this study in order to provide an understanding of the state of the art of on-line monitoring tools and associated analytical methods, and to evaluate the performance and condition of critical power plant components in real time. Consideration is to be given to both conventional and combined cycle thermal plants. For more information on the program and full project listing, please visit CEATI 2015 / 2016 G-11
