Realistic and Achievable Submarine Transmission
Building new transmission is important and we need to plan and build projects with the least environmental impact, lowest wildfire risk, and least disruption to communities. Most people don’t want to see transmission towers and lines, and clearing land for transmission rights of way has an environmental cost. There is added danger too, since transmission and distribution lines can sometimes trigger dangerous, destructive wildfires. For all these reasons new transmission lines have become almost impossible to build.
TRED’s projects work better and can be built. Using advanced HVDC (high-voltage direct current) transmission technology it is possible to efficiently transmit power over long distances underwater and underground. Our cables are buried underground and placed on the seabed out of sight. The environmental impact is small. And offshore/underground circuits give grid operators more flexibility to isolate and shut down above-ground transmission circuits at times of high wildfire risk. Using a sea-based and underground route is key to bringing clean power right into California’s cities where more power, reliability and resiliency are needed.
