What Is Power & Energy Society?

Power & Energy Society (PES) is the IEEE technical society dedicated to the science and engineering of electric power generation, transmission, distribution, and utilization. Established within IEEE as one of its largest and most active technical societies, PES brings together engineers, researchers, and practitioners whose work spans conventional power systems, renewable energy integration, smart grid infrastructure, and energy storage. The society draws its intellectual lineage from electrical engineering, thermodynamics, control theory, and materials science, reflecting the breadth of disciplines required to design and operate modern power systems.

With more than 40,000 members in chapters across six continents, PES operates as a global professional community. Its activities center on three interconnected pillars: standards development, technical publications, and professional education. These functions collectively advance the reliability, efficiency, and safety of the world's electrical power infrastructure.

Technical Activities and Committees

PES organizes its technical work through 17 Technical Committees and 4 Coordinating Committees, each focused on a distinct segment of the power and energy domain. Committee areas include transformers, substations, energy development and power generation, power system relaying, and transmission and distribution. Each committee sponsors working groups that address emerging technical problems, revise existing standards, and produce reports on topics such as grid resilience, asset management, and power quality. The IEEE Power and Energy Society technical activities framework also coordinates with other IEEE societies and external organizations such as CIGRE and EPRI on issues that cross disciplinary boundaries. Working group outputs feed directly into standardization efforts and shape engineering practice worldwide.

Standards Development

PES produces nearly half of all IEEE Standards annually, a volume that reflects the breadth of its technical scope. Key standard families include the C57 series on power transformers, the C37 series on switchgear and circuit breakers, IEEE 1547 on the interconnection of distributed energy resources, and IEEE 2800 on inverter-based resources at the transmission level. These standards set performance requirements, testing procedures, and interoperability criteria that utilities, equipment manufacturers, and regulatory bodies rely on globally. The IEEE Standards Association energy practice coordinates PES standards work with broader IEEE standardization policy and supports international harmonization with IEC counterparts. As the grid evolves to incorporate higher shares of variable renewable generation and distributed storage, PES technical committees have accelerated work on protection coordination, synchronized measurement, and grid-forming inverter behavior.

Publications and Education

PES publishes several peer-reviewed transactions, including IEEE Transactions on Power Systems, IEEE Transactions on Energy Conversion, IEEE Transactions on Power Delivery, and IEEE Transactions on Smart Grid. These journals provide archival records of research on topics ranging from optimal power flow algorithms to high-voltage insulation materials. The society also publishes IEEE Power and Energy Magazine, which carries technically rigorous articles written for practitioners. Annual conferences, including the IEEE PES General Meeting and the IEEE PES Innovative Smart Grid Technologies conference, convene researchers and engineers to present results and debate technical directions. Educational programs include online courses, webinars, and certification preparation materials targeted at both early-career engineers and experienced professionals seeking to update their knowledge as the industry transitions toward decarbonization.

Applications

Power & Energy Society technical work has applications in a wide range of disciplines, including:

• Electric utility planning, operations, and grid reliability analysis
• Renewable energy integration and inverter-based resource interconnection
• Smart grid communications, sensing, and advanced metering infrastructure
• High-voltage direct current (HVDC) transmission system design
