Section 7.1 - General Features of Hydro Electric Project
Overview
• Hydroelectric converts water potential energy into work
• Energy output is based on head – difference in height
• Hydroelectric power is a renewable resource• Water is “fuel” but still needs management• Typically power is transmitted over longer
distances• China is now the production leader with the 3
Gorges dam.

Types of Development
• Run of the River – Flow Rate and Volume of River• Reservoir
• Ponding – Peak Use• Seasonal Storage – Dry Time Use - Summer• Long Term Storage – Base Load
• Pumped Storage• Pure Pumped Storage – Between two
reservioris• Pump-Back Pumped Storage – River and
Storage• Seasonal Pumped Storage – Demand and
River Flow
