Olsson Industrial Electric completed a comprehensive modernization of the station service electrical distribution system at The Dalles Dam, a 2100 MW hydroelectric power generation facility, as the prime contractor. Olsson upgraded the existing 1950’s vintage control system, rerouted and installed new power distribution feeders, replaced wire distribution to improve the quality of the cable infrastructure, and connected a secondary power source to create internal redundancy. The electrical upgrades improved turbine control, power generation efficiency, system reliability and serviceability.
