Small is Profitable describes 207 ways in which the size of electrical resources”–devices that make, save, or store electricity–affects their economic value. It finds that properly considering the economic benefits of “distributed” (decentralized) electrical resources typically raises their value by a large factor, often approximately tenfold by improving system planning, utility construction and operation, and service quality, and by avoiding societal costs. Small is Profitable introduces engineering and financial practitioners, business managers and strategists, public policymakers, designers, and interested citizens to the new value opportunities presented by considering these economic benefits. It also provides a basic introduction to key concepts from such disciplines as electrical engineering, power system planning, and financial economics. “
