Summary of Scope of Work:

This project involves upgrading the McNary Navigation Lock electrical power and control systems. The Navigation Lock has been in service since 1954, and all the major electrical equipment is original. The electrical and control systems had a design life of 50 years, and now have the distinction of being the oldest systems in the Columbia-Snake River navigation system.   

This project includes extensive electrical and control improvements to ensure the reliability and operability of the navigation lock for another 50 years. The scope includes providing new feeders from the powerhouse to the navigation lock; replacing the 480-volt power distribution equipment; installing cameras; repairing certain grounding details; and replacing the control systems for the downstream gate, upstream gate, drain valves, fill valves, and bascule bridge. It also includes replacing the upstream and downstream control stands for the navigation lock. The new oil-filled pad-mounted substation transformers will be located away from the river and will include spill containment systems. The following is a summary of the project scope from the Design Documentation Report. 

Power

For the power distribution system, the scope includes replacement of the feeders from Station Service to the navigation lock; the step-down transformers; the navigation lock switchgear; the navigation lock motor control centers; the bascule bridge motor control centers; branch circuits; and branch circuit loads and panelboards that were or will be in the switchgear and motor control centers. The scope also includes replacement of corroded grounding electrode conductor connections within the navigation lock and the addition of ground busses to existing panelboards fed by the new equipment. 

1. Feed power from Station Service to navigation lock at 13800V 
2. Transform voltage down to 480V 
3. Switch and protect power for MCCs 
4. Feed power to motor control centers 
5. Convert from ungrounded to high-resistance grounded 480V distribution 
6. Switch and protect power for branch loads 
7. Provide power to derrick crane

9. Provide power to existing non-motor loads, but not replacing lighting or lighting panelboards 
10. Provide bridge motors and brakes 
11. Provide VFD and FVR starter for downstream gate 
12. Provide space for future VFD for upstream gate 
13. Feed power to lock stand panelboards 
14. Raceways and cable tray for wire and cable 
15. Repair grounding electrode connections 
16. Add ground busses to existing panelboards fed by new equipment 
17. Demolish 2600-ft. of asbestos-cement cable trays 
18. Demolish power center (with transformer) in Control Building 
19. Demolish feeders from dam to power center
