Gas Insulated Substation

Project 969-17
Moundsville, WV

Great Lakes constructed a gas-insulated substation expansion on the Ohio River in West Virginia. More closely resembling a treatment plant structure than a typical substation, the two-story concrete foundation holds cabling fed to specialized equipment in the pre-engineered metal building constructed above. A crowded site requires careful planning to sequence this work between multiple contractors. Installation included the building, multiple foundations throughout the substation, and over 10,000 LF of duct bank conduit.
