Substation Replacement



Nameplate Capacity

Keystone provided project management, engineering, and design services to support replacement of existing substation and removal of field location switch racks. The project included engineering front end scope development, TIC development, bid evaluation, detailed design execution, and construction support. The project identified process unit electrical loads for power distribution replacement, specified substation equipment, incorporated a closed transition main tie main switchgear section, and implemented redundant A & B power feeds from primary 35KV substation yard. The substation building implemented a modular industrialized building design with vertical construction to accommodate space constraints. Electrical infrastructure within the building included LV switchgear, LV induction motors, power distribution, industrial UPS system, UPS power distribution, and DCS equipment space for upgrade of unit controls. The UPS power distribution consolidated and centralized existing unit UPS system. Cable tray systems, cabling, structural supports, foundations, and building were completely installed within an operating refinery. Final cutover and commissioning were performed during a planned turnaround outage.
