Power from a Water Supply System: A Resource Which Can Be Tappedby Chenchayya Bathala, Parsons Brinckerhoff Quade &, Douglas Inc, Sacramento, CA, USA,
Abstract: There are numerous water supply systems from which hydroelectric power could be developed without impending the regular operational schedule. The basic principle of operation is not different from the conventional reservoir plants or run-of-river hydroplants. However, there are some differences. Some of the salient features to be investigated as part of a feasibility study for adding a powerplant to an existing water supply system include preliminary investigation, development alternatives, energy production, environmental concerns, pressure rise upon load rejection, financing and power purchase agreement. The study concludes that it is technically feasible to install hydro plants in an existing water supply system. While environmental concerns may not pose a great threat, control of pressure rise upon load rejection requires a thorough analysis.
