Detroit and Big Cliffs Dam Reliability Upgrades

Overview

Olsson Industrial Electric completed a project to upgrade integral electrical components at the respective powerhouses for Detroit and Big Cliff Dams. Olsson replaced vintage 13.8 kV gallery switchgear in both powerhouses. The Detroit Dam switchgear was previously destroyed in a fire, lowering the dam’s output potential.
