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.

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. 2015 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.

Transmission Underground Cables The Transmission Underground Cables (TUCIG) Interest Group provides a forum for the exchange of information on cable asset management, as well as establishes techniques and tools for improving installation, maintenance and replacement procedures for fluid-filled and XLPE High Voltage underground cable systems. A Guide on Factory Inspection and Test Plans for Manufacturing and Delivery of XLPE When utilities plan to purchase cross-linked polyethylene (XLPE) cables for underground transmission projects, careful consideration must be given to the factory testing and related issues to assure that the utility can effectively assess the quality of the manufactured cable and accessories. This effort begins by communicating the requirements of the test program, as defined in the purchaser s specification to the cable manufacturer. To be effective, utility personnel must understand the generalized testing requirements used in the industry and the purposes of the various tests to be performed. Once the manufactured goods are delivered, the utility personnel must be able to assess the condition prior to accepting the materials. The developed guide covers the key portions of the implementation cycle of an underground cross-linked polyethylene (XLPE) transmission cable project, from the initial engineering design through the procurement and final commissioning. The key concepts reviewed were prequalification of suppliers, factory acceptance testing, and receipt of materials after shipping. 2015 Portfolio Highlights Transmission Cable Reference Manual: Installation & Inspection Chapter: - Trenching for Direct Buried & Duct Bank Cable Installations - Cable Pulling - HPFF, SCFF and XLPE - Pipe Installation for HPFF Cables - Manholes & Risers (Including Racking and Hardware) - Cathodic Protection & Protection of Manhole Covers - Field Testing - Documentation of the Completed Installation Continuous Improvement in Work Practices A Guide on Factory Inspection and Test Plans for Manufacturing & Delivering XPLE Transmission Cable Systems HPFF Joint Casings Corrosion Protection Aging Tests Transition Joint Technology XLPE-XLPE and XLPE-HPFF/LPFF 2015 Executive Committee TUCIG Chair: Frank Frentzas, Exelon TUCIG Vice-Chair: Hon Suen, BC Hydro Topics & Issues at a Glance Asset Health Index Models Design & Construction of HV Underground Cable Systems Preventive & Corrective Maintenance Strategies for Life Cycle Management Means of Minimizing Environmental Impacts Worker Safety Technical Advisor Steve Haddock Mr. Haddock is a utility expert with 34+ years of experience maintaining & managing transmission lines and cables equipment.

Distribution Line Asset Management Over the past few years, the Distribution Asset Life Cycle Management (DALCM) Interest Group s focus has broadened to encompass all aspects of Asset Management. It is now focusing on the coordination of Utility activities to realize value from assets by balancing costs, opportunities and risk against the desired performance of assets to achieve organizational goals in the near and long terms. Assets are broadly defined as an entity that has potential or actual value to the Distribution System. To reflect this wider focus, the group name has been changed to the Distribution Line Asset Management (DLAM) Interest Group. The mission of the DLAM group is to share current practices and processes regarding the management of distribution assets including planning, purchasing, installing, commissioning, operating, maintaining and the disposal of assets. Distribution Roadmap Update The distribution system of the future is expected to be very different from the distribution system of the past.

Power Quality & Advanced Technologies The objective of the Power Quality & Advanced Technologies (PQAT) Interest Group is to share information and experience with respect to arising power quality issues and mitigation techniques, in addition to exploring the more advanced uses of PQ data for equipment predictive maintenance, DG integration and power system automation. Voltage Fluctuations Caused by Transient Clouds in Distribution Systems with a High Level of PV Installations The penetration of photovoltaic (PV) generators into distribution systems is creating a new power quality issue for utilities; namely the voltage fluctuation due to rapid PV output change that is caused by transient clouds. A piece of cloud can move quite fast to block/unblock solar irradiance received by a PV panel. The resulting change of PV panel output can be as high as 80% and it can occur within 10 to 30 seconds. When a feeder has a high penetration of PV generators, the resulting power quality impact can be significant. This is a PQ concern utility companies must prepare for in view of the widespread adoption of PV generators. This study determines the impact of transient clouds on a typical North American distribution system with varying roof-top PV penetration levels, as well as identifies and evaluates potential solutions to the problem. Through preliminary investigations of studying the rate of PV power output changes, it can safely be concluded that transient clouds cannot cause voltage flicker in the traditional sense. Therefore, the main concern of this project is the voltage fluctuation. Furthermore, it has also been proposed to use reactive power control instead of energy storage, as a solution to the problem. If this solution works, it will be much more attractive and economical than the current energy storage solution. 2015 Executive Committee PQAT Chair: Devinder Bahra, Hydro One Networks Inc. PQAT Vice-Chair: Cristiana Dimitriu, Con Edison Analysis of Parallel and Series Resonance on the Electrical Distribution System With the rapidly growing proliferation of harmonic emitting sources, such as nonlinear loads, adjustable drives, and inverter based distributed generators, distribution systems are facing an increased potential of harmonic amplification caused by parallel and series resonances in the networks. These resonances can result in voltage distortions beyond acceptable limits and potentially cause failures of utility and customer owned equipment. The objective of this study is to present a comprehensive review of parallel and series resonance in the electrical distribution system, including, but not limited to, harmonic resonance and ferroresonance. The report includes a general discussion on the nature of these conditions and their impact on utility and customer owned equipment. Methodologies for identifying resonant conditions from power quality data are presented and described in detail. Techniques that may mitigate or eliminate parallel and series resonance conditions are also examined, in addition to more pro-active approaches that could be utilized to prevent resonance issues from occurring in the first place. 2015 Portfolio Highlights Application Guide for Coordination of Electrical Distribution Feeders and Gas Pipelines Analysis of Parallel and Series Resonance on the Electrical Distribution System Voltage Fluctuations Caused by Transient Clouds in Distribution Systems with a High Level of PV Installations Technical Advisor Jerry Lepka Mr. Lepka draws from his experience working with Ontario Hydro (Hydro One / Ontario Power Generation) in the areas of maintenance and operation of high-voltage transmission facilities.

Distributed and controllable energy storage devices offer a number of benefits, such as reducing peak load, decreasing line losses, enhancing power quality, and providing stand-by power. In identifying these shortcomings, CEATI s PQ group undertook the project - Electrical Energy Storage in Distribution Systems for Mitigation of Power Quality Issues. This project provides a comprehensive report on the state-of-the-art in energy storage systems used and/or available for mitigating power quality problems in distribution systems. The report includes a description of different energy storage technologies, their modelling and control, as well as their applications in grid-connected & microgrid operations. The project illustrates techniques for determining the size, location and effectiveness of specific technologies that utilities can use for meeting their power quality requirements. Anecdotal case studies and summaries of operating experiences with energy storage systems in North America and globally are included for the benefit of utilities contemplating use of energy storage systems for addressing power quality issues.

The report will identify and recommend appropriate maintenance and testing programs, complete with field verification checks to ensure the integrity of the ground connection point, including its current carrying capability. While electrical interactions (inductive, capacitive and conductive) are well explained during steady state and fault conditions, one extreme condition, when the soil becomes ionized and direct arcing occurs between the high voltage tower/pole foundation and the underground pipeline, is not well defined. Existing studies do not provide reliable assessment methods to establish a dependable but realistic separation distance. The objective of this project is to provide an assessment tool for the determination of a safe separation distance between high voltage power line tower/pole footings and underground pipelines.

Customer Energy Solutions The Customer Energy Solutions (CESIG) Interest Group assists electrical and gas utilities, as well as the related energy services industry and governmental organizations, to achieve energy and demand reduction through the analysis, investigation and demonstration of Demand Side Management (DSM) technological applications. Through the CESIG Group, participants are able to pilot and assess new technologies, develop new standards and guidelines for energy efficiency and DSM measures, as well as provide new technology solutions for customer problems. Residential HVAC Zoning Controls Central forced-air furnaces are the most common home heating technology used in Canada. Today's furnaces are much more energy-efficient than in the past and new construction and retrofit applications have helped to transform the market. The opportunity for additional energy savings may be achieved through improving the control or distribution of the existing heat energy devices within the home regardless of whether it is heated via a standard, mid or high efficiency furnace. This project identifies commercially available Residential HVAC zoning technologies, and estimates the achievable savings potential, risks and market barriers for adoption. These HVAC zoning technologies include controls, dampers or registers that can be used to retrofit a forced air system, create zoned heat, improve occupant comfort and encourage natural gas savings. This study will be used to determine the feasibility of launching a pilot and offering Energy Efficiency & Conservation funds for these technologies across the residential market sectors. 2015/2016 Portfolio Highlights Micro-CHP Energy Savings and GHG Emissions Assessment Estimating Associated Peak Demand Savings from Energy Conservation Measures Residential HVAC Zoning Market and Pre-Feasibility Study Energy Savings in Buildings with Energy Management Systems 2015 Executive Committee CESIG Chair: Chris Milan, Bonneville Power Administration CESIG Vice-Chair: Jon Feldman, Ontario Power Authority M-6 CEATI 2015/2016 Topics & Issues at a Glance End Use Technologies: Lighting Motor Systems HVAC Energy Management Systems Demand Side Management Best Practices Supporting Regulations, Codes & Standards Strategic Issues Technical Advisor Eric Mazzi Dr. Mazzi has over 25 years of experience in applied engineering practice, policy research, and teaching.

The EMVWG will provide a platform for best practices and technical exchange and will also help to develop projects in the area of EM&V that may be beneficial to its participants. Examples of discussion topics and projects that the group could explore include: best practices for impact evaluation at site specific M&V customer projects; baseline modelling, monitoring, and tracking; reporting of energy savings performance over multiple years; and quantifying energy savings from behaviour change programs. The inaugural call for the EMVWG was held in September 2015. For more information on the program and full project listing, please visit www.ceati.com/cesig CEATI 2015/2016 M-7

Smart Grid The Smart Grid Task Force (SGTF) assists electric utilities in successfully deploying ICT and automation systems so that they can readily integrate utility-scale and distributed renewable energy sources, storage, EVs, DR, microgrids and building energy management systems while maintaining the highest degree of service reliability, safety, cybersecurity etc. The group defines a direction for future research and helps utilities transition from vision to operational Smart Grid Systems. Impacts on Distribution System Operations When Integrating DER Distributed Energy Resources (DER) is the new reality. Electric utilities are currently integrating these resources into the grid. DER includes demand responses, building energy management, rooftop solar PV generation, energy storage systems, EV battery charging, microgrids, distributed generators, and others. Operating the distribution system grid while integrating DER presents significant challenges to distribution system operators. The objectives of this project are to identify the major impacts on power system operations associated with the integration of DER and to determine the most appropriate solutions and remedial measures to resolving these impacts. The solution involves system architecture, communications infrastructure and automation technologies with associated changes in the work process and product design. The resulting system should also be able to accommodate Smart Grid applications that utilities could consider in the near future. 2016 Project Program Develop an Industry Initiative for Interoperability to Implement Smart Grid 2.0 Governance and Standardization of Data Inputs for Distribution Management Systems The Future of Cloud Computing and Big Data Analytics in Electric Utilities 2015 Executive Committee SGTF Chair: Joe Schatz, Southern Company SGTF Vice-Chair: Raed Abdullah, Hydro Ottawa Limited Interfacing Guide to Estimate DMS/OMS/SCADA Benefits from Systems Smart with Grid Enterprise Applications Business FLISR and IT VVO Systems (Phase for 1) IT/OT Integration in Smart Grid Some leading electric utilities are increasingly interfacing DMS/SCADA Systems with Enterprise Business IT Systems.
