Figure 6 Vault Under Sidewalk ata Ana Buck .....Wl� New Construction When the Agency needs 12 CFS through this station it would open flow through the turbine, using a combination of the automated valve and the wicket gates to minimize sudden pressure changes. The PRV could be kept at a higher setpoint so that it does not typically operate unless there were an unusual demand for water at this point. The control valve and wicket gates would be remotely operated to shut down flow in the turbine when appropriate, as well. The electricity generated by the hydro -turbine at this location cannot offset an adjacent City of Santa Ana load, as the only electric load at this location is instrumentation and lighting. It is anticipated that the generated electricity will be used to off -set another city meter through the Renewable Energy Self -generation Bill Credit Transfer mechanism know as RES BCT. This allows the value of electricity generated by the turbine to be metered by SCE on a TOU-GS-1-C rate schedule. The dollar value of this electricity can be used to offset the generation component at one or more city electric meters. The power produced by this flow and pressure difference is calculated here. The pressure drop is lower than for the other turbines, because the discharge of the turbine goes to the higher -pressure zone in the city, so the typical pressure drop is from 177 to 100 psig.
