This guide describes alternatives that hydroelectric power plant owners should consider when undertaking a rehabilitation of the facilities. It is useful in ensuring that potential improvements are not overlooked in the owner’s process.
This guide is directed to the practicing engineer in the field of hydroelectric power for the purpose of providing guidance in the decision-making processes and design for rehabilitation of hydroelectric power plants.
Revision Standard – Active. This guide is intended for the hydroelectric power industry to assist hydroelectric power plant owners, operators, and designers in the economic (feasibility) and technical evaluation (electrical aspects) of existing hydroelectric installations for rehabilitation. It addresses conventional hydropower. Portions of this guide are relevant to pumped storage, but the unique features of pumped storage are not covered. Feasibility study results may indicate redevelopment of the site. Redevelopment will not be treated in detail in this guide. This guide covers all generating equipment up to and including the main transformer and typical auxiliary equipment.
