Summary of Scope of Work:

The existing navigation lock electrical unit substation, switchgear, transformers, and motor control centers are original to the dam and have been operating for over 55 years. The equipment has far exceeded the typical equipment service life and needs replacement.   The age of the equipment has made procuring replacement parts difficult. Operation and maintenance of the equipment remain more hazardous to workers due to the age and arc flash category rating of the equipment.  Failure of the electrical system could impact the operation of the lock which would ultimately affect navigation on the Snake River.

This project involves replacing existing medium and low voltage switchgear lineups and their associated feeder cables with modernized medium and low voltage switchgear and motor control center lineups at Lower Granite Dam Navigation Lock.  

The main features of work includes:

Provide and install one (1) new medium voltage switch gear.

Provide and install one (1) new low voltage switch gear.

Provide and install two (2) new motor control center lineups.

Provide modernized controls for existing electrical loads.

Provide one (1) new 4,160/480-V 1,000 kVA transformer.

Provide lighting load centers to replace existing panels.

Provide new concrete housekeeping pads for new electrical equipment.

Provide new cable trays and conduits where required by circuit reconfigurations and to bring fill ratios to levels that meet electrical codes.

Provide an HMI screen to replace an existing annunciator panel.

Demolish existing medium and low voltage switchgear, motor controls centers, and transformers.

Demolish the existing 480VAC feeders routed from existing low voltage switchgear and motor control centers.

Seal hatch and any expansion joints, or cracks, to prevent water intrusion in an existing electrical room.

This work is anticipated to be performed in 2028 and 2029, with cutover power construction work being completed during the 2028 and 2029 navigation lock outages. Access to the navigation lock deck and electrical substation rooms will be available for workers and equipment.
