This is an ambitious book on world power markets. If there is any power-related topic that interests you—generation, public policy, transmission, pricing of power derivatives, capacity, system operation, regulation, security—this book will have something to say about it. The downside is that, even at 519 pages, the book is spread too thin. Explanations tend to be brief. Some—but certainly not all—are too insubstantial to be useful. The rest, although informative, tend to read like an engineering manual—technical and hardly user friendly.
