This is where the nation's public policy organizations, trade associations and think tanks weigh in with analysis on Infra issues. The Pacific DC Intertie (also called Path 65) is an electric power transmission line that transmits electricity from the Pacific Northwest to the Los Angeles area using high voltage direct current (HVDC). Scientific studies have not clearly shown whether exposure to EMF increases cancer risk. Primarily higher voltage, long distance transmission lines in Wyoming. If properly configured, direct current transmission could also help mitigate operational issues with wind and solar generation such as a mismatch in generation in relation to the need for increased ancillary services associated with renewable generation.

A recent study of more than 50,000 adults with several common types of cancer found no increase for people living near high-voltage transmission lines. Other factors include regulatory issues, including siting issues; difficulty in deploying multi-terminal HVDC networks; preference for smaller, lower-cost solutions; and a lack of standardization across projects. Tell them what you think. If you smell natural gas or suspect a leak, leave the area immediately and call Piedmont Natural Gas at. The poles that carry high-voltage transmission lines are tall, towering anywhere from 50 to 180 feet above the ground. We have already engaged nearly 280,000 users, and hoping to add many more as interest continues to grow. One advantage of direct current over AC is that DC current penetrates the entire conductor as opposed to AC current which only penetrates to the skin depth. These energy fields surround us all the time. Campbell-Keister-McDowell Tranmission Project. Many of the towers of the Intertie are of this simple, slender design, The slender tower's base tapers down to a single point that is bolted to a concrete anchor, The slender tower is supported laterally by four guy-wires, The Pacific Intertie outside of Benton, California.
