Juan de Fuca Cable Project
Photo credit: Tim Whitehead
Project Description
The Juan de Fuca Cable is a proposed underground and undersea 150kV, 550MW High Voltage Direct Current (HVDC) Light® cable designed to run bi-directionally from View Royal, British Columbia to Port Angeles, Washington. The proposed total length of the cable is 30 miles. Of this, about 22 miles is in the strait of Juan de Fuca, buried 3 to 6 feet deep beneath the sea floor. Seven miles of the line runs underground on Vancouver Island in British Columbia, and one mile is underground near Port Angeles, Washington.
Important characteristics:
- The result of burying the cable is no visual impact, audible noise, or changes to usage of the overlaying land.
- Terrestrial portions of the line will be buried under existing roads, railroad rights-of-way, or utility corridors, to minimize the impacts on surrounding areas.
- Horizontal directional drilling will help to minimize the impact to sensitive nearshore habitat. An onshore drill will bore underneath the shore area and intertidal zone, exiting more than half a mile from the drilling site.
- The cable will be built with highly efficient HVDC Light® technology, which allows more power to be transmitted across fewer lines, does not emit fluctuating EMFs, and provides faster and more accurate control of the power.
Status
The project received all major permits in the United States and Canada by 2009 and currently several permits are undergoing renewal. The cable would be operational 24-26 months from financial close, possibly mid-2015.
