Cascade Renewable Transmission System 320kV
Sector: Hydro • Location: Oregon, United States of America
Source: Dodge
The Cascade Renewable Transmission System is a proposed 320-kilovolt high-voltage direct current (HVDC) transmission line that would span approximately 100 miles between The Dalles and Portland. The majority of the HVDC line would be installed in the bed of the Columbia River using a Hydro Jet Cable Burial Machine, or jet plow . The jet plow temporarily fluidizes sediment in an approximately 18-in
