It is the most up to date written material for those preparing for the new 2015 NERC System Operator Certification Exams. “Electric Power System Reliability-2006” was first offered in July, 2006. It was popular and served its purpose. “EPSR-2007” was an updated version of the 2006 book including the new and revised NERC Standards on which the July, 2007 NERC exams were to be based and some new questions to promote understanding. The new NERC exams were delayed and ultimately implemented in July, 2008. NERC implemented new System Operator Certification Exams in 2012. The exams went live in February, 2012. The exams were based on the NERC Reliability Standards effective October 1, 2011. New NERC System Operator Certification Exams were implemented in January, 2015 and test on the NERC Standards which were effective on January 1, 2014; particularly the NERC Glossary of Terms and the BAL, COM, EOP, INT, IRO, TOP, VAR Standards. This 2015 First Edition is an update to the 2014 First Edition. It includes lessons learned from recently taking the NERC RC exam. It is revised to include Standards approved by FERC that become effective during 2015. It emphasizes the Standards in effect as of January 1, 2014 on which the current (2015) exam is based. The presentation of the Standards highlights those considered to be most important in preparing for the NERC exam and those which have the greatest impact on system reliability. As always, we will present the Standards in the context of power system fundamentals, the understanding of which is required to properly implement those Standards. The NERC Approved Reliability Standards are organized into fourteen topical blocks on the NERC website: BAL—Resource and Demand Balancing CIP—Critical Infrastructure Protection COM—Communications EOP—Emergency Preparedness and Operations FAC—Facilities Design, Connections and Maintenance INT—Interchange Scheduling and Coordination IRO—Interconnection Reliability Operations and Coordination MOD—Modeling, Data, and Analysis NUC—Nuclear PER—Personnel Performance, Training and Qualifications PRC—Protection and Control TOP—Transmission Operations TPL—Transmission Planning VAR—Voltage and Reactive This book is organized in seventeen chapters each addressing a fundamental of Power System Reliability. Rather than present the Reliability Standards strictly in the NERC alphabetic Standards blocks, the Standards are presented in the context of the appropriate power system fundamentals. This organization is designed to provide the technical information required to understand the Standards and provide relevance and perspective to highlight the purpose of each Standard or group of Standards. This presentation format is designed to frame each group of standards so that information can be more easily assimilated and retained by electric power system operating personnel. Each chapter is designed around a fundamental of Power System Reliability and its associated NERC Standards. Background information is presented to explain the purpose, intent and technical relevance of the Standards in that group. Key requirements of the Standards are summarized. Finally, any remaining requirements from the Standards group are presented for completeness. This book is not intended as a complete and comprehensive representation of the NERC Reliability Standards. Power system professionals should continue to consult the NERC web site and other NERC publications for a comprehensive and current statement of the NERC Reliability Standards and their requirements, measures and compliance levels. Chapter 13 contains a description of the details of the NERC System Operator exams and the process for registering for those exams. Those individuals preparing for the exam may want to turn there first.
