Bonneveille Power Administration is proposing to replace equipment in the existing Longview and Tillamook substations to facilitate upgrades to new digital technologies. The new equipment upgrades would include cable trays, racks with direct current power boards consisting of chargers, wiring, and by-pass switches at both substations. Additional work at Tillamook Substation would include the installation of two tier battery racks to accommodate a new 48 volt/360 ampere battery and associated platings.
