Explanation
1. BACKGROUND
This ordinance authorizes the Director of Public Utilities to enter into a professional engineering services contract awarded through the City’s Request for Proposal process with Patrick Engineering, Inc., for the Relay Upgrade Drawing Preparation Project, CIP #670883-100001, in an amount up to $580,227.00 for the Division of Power.
The Department of Public Utilities (DPU), Division of Power (DOP), owns and operates a public electric distribution system. DOP intends to replace 14.4kV power distribution electromechanical and solid-state relays reaching their end of life with modern microprocessor based protective relaying. These relay replacements will allow for better coordination with downstream devices and allow for fault analysis.
This project will prepare installation drawings for the replacement of 14.4kV feeder protection relaying and control switches at three substations, for a total of 30 relay cubicles being upgraded.
1. Jackson Pike Substation, located at 2500 Jackson Pike Columbus, OH 43223; consists of 14.4kV distribution in a main tie main tie main arrangement. There are a total of 9 cubicles; 2 mains, 1 tie, and 6 feeders receiving new relays in this substation.
2. Furnace Substation, located at 400 Furnace St., Columbus, OH 43215; consists of 14.4kV distribution in a main tie main arrangement. There are a total of 10 cubicles; 2 mains, 1 tie, and 7 feeders receiving new relays in this substation.
3. West Substation, located at 56 N. Wheatland Ave. consists of 14.4kV distribution in a main tie main arrangement. There are a total of 11 cubicles; 2 mains, 1 tie, and 8 feeders receiving new relays in this substation.
The Community Planning Areas is 99 - Citywide as these electric substations directly serve multiple planning areas in the city.
TIMELINE & FUTURE MODIFICATION(S):
The schedule for this project is expected to take 12 months.
