Model Study of Proposed Expansion - Encina Power Plant San Diego Gas and Electric Company

Abstract

Because of present and anticipated future power demands, it is now necessary for the San Diego Gas and Electric Company to expand the generating capacity at its Encina Power Plant. In order to provide sufficient cooling water for the expanded plant, the existing inlet tunnels and associated structures must be modified. Because the complexity of the structure made it essentially impossible to analyze accurately the flow pattern and associated head losses mathematically, a model study was undertaken at the St. Anthony Falls Hydraulic Laboratory. The hydraulic model was built and tested to assist in the development of a satisfactory design and to verify the final design.
