About the Book Energy Efficiency in Electrical Utilities is a comprehensive guide designed for engineers, managers, students, and policy makers working in the electric power sector. As global demand for electricity continues to rise and the climate crisis intensifies, improving the efficiency of how electricity is generated, transmitted, and consumed has become one of the most urgent priorities of our time. This book walks the reader through the entire energy supply chain—from power generation and high-voltage transmission to distribution losses, end-user appliances, and demand-side management. It combines foundational theory with practical case studies, calculation examples, and best practices drawn from real utility experience. Topics include demand-side management, loss reduction in T&D networks, the role of renewable energy integration, power factor correction, smart metering, and the economic and regulatory frameworks that drive efficiency programs. Special attention is given to the Indian power sector, but the underlying principles are universal
