This slide presentation outlines strategies to ensure electric power reliability for Greater Cincinnati Water Works (GCWW). The evaluation addresses five basic issues that include: power failure risk assessment, what were GCWW's risks for a system-wide power failure; hydraulic evaluation, what would happen to the facilities and system in such an outage; workshop addressing the level of service which should be established as the minimal acceptable threshold; standby power assessment, what were the associated power needs; and, cost benefit analysis, prioritize needed improvements. Project results and conclusions included: provide capital improvement plan (CIP) funding to the top 5 - 6 ranked standby power projects, providing 1-Day backup capability; cost benefit evaluation was not the crucial factor for selecting where to install backup power systems; final ranking was determined on the system hydraulics and the function of each facility within the transmission and distribution network; cinergy has a robust system restoration plan; GCWW is a Critical Customer for Cinergy; Cinergy Recommendations for Power Restoration Planning; 3 days is possible, but 7 days would be more prudent; and, restoration time depends on outage conditions.
