This book is a “unified, consistent and comprehensive treatment of the theories and practicalities of regulation in modern power-supply systems,” according to the publisher. Arranged in four parts, it addresses both traditional regulatory frameworks and liberalized and re-regulated environments. An introduction characterizes power supply, including engineering, economic and regulatory viewpoints. The second part presents the fundamentals of regulation, and the third part examines the regulation of particular components of the power sector in detail. Advanced topics and subjects still open or subject to dispute constitute the fourth part.
