This book is aimed at providing a comprehensive treatment to the electrical network access and pricing problem. The transmission pricing problem, for some regulatory frameworks, is a mere fixed cost allocation problem, while for other others, it also accounts for operational costs like loss and congestion. This book provides a detailed description of both the approaches, with appropriate reasoning behind adopting a particular way of pricing. The book compares and contrasts various fixed cost allocation methods, in addition to discussion of the transmission loss allocation problem. The book sheds light on established practices in transmission pricing and rights in some of the power markets of the world. The emphasis here is to establish concepts in a simple and lucid manner. Important discussions are supported by appropriate numerical examples.
