MCES Fridley Campus Industrial Electrical Rehabilitation

The Pump Station 5 facility in Minneapolis, Minnesota, was built in the mid-1920s and put into service in 1927. The facility is a combined low-service and high-service pump station. To remove the risk of major outages from electrical equipment failure, the City of Minneapolis Public Works selected TKDA to upgrade electrical equipment to enable safe and energy-efficient operations, inspection, and maintenance.

The design services for the project included:

• Replacing and relocating the single main 13.8kV switchgear with two new 13.8kV/2.4kV electrically redundant stand-alone substation shelters at the new greenfield location within the Fridley campus
• Designing and installing new underground duct banks, manholes, and MV cables to redistribute the 13.8kV power to existing facilities
• Removing and replacing six low-service pumps (200-350HP) and eight high-service pumps (600-2000HP) obsolete 2400V Synchronous Motor controllers
• Removing and replacing two 480V induction motor pumps (75HP & 150HP) VFDs
• Removing and replacing centralized pump floor local pump and discharge valve operator stations
• Reconfiguring existing Pump Station 5 Rockwell Controllogix PLC controls and the added networked Allen-Bradley 857 Motor Protection Relays and GE SPM Synchronous Motor Protection relays for controlling the starting, synchronizing, and protection of the Synchronous Motors
• Adding a new electrical room by repurposing existing space from an abandoned control room, generator room, and break room
• Removing and replacing the existing 2400V and 480V electrical switchgear/boards inside Fridley Softening Plant to add load capacity and address safety and redundancy concerns
