Linking the West with wind
Mar 05, 2011 - WindPower Engineering - windpowerengineering.com
There are currently six major transmission projects under development in Wyoming:
TransWest Express: a 600-kV DC transmission line that offers the shortest way to bring the state’s renewable power to people in the Desert Southwest, an area comprising parts of California, Arizona, and Nevada. 3,000-MW line will span 725 miles.
Energy Gateway: designed as double-circuit and single-circuit 500-kV AC and some single-circuit 230-kV AC transmission lines between Wyoming and Idaho (Gateway West), and Wyoming and Utah (Gateway South). The lines will have a total capacity of 4,500 MW and span 2,000 miles.
Wyoming-Colorado Intertie: a 345-kV AC transmission line between Wyoming and Colorado will deliver wind resources to the Front Range, a highly-populated area in Colorado, at a competitive price. The 850-MW line will span 180 miles.
High Plains Express: a 500-kV double-circuit AC transmission line between Wyoming and Arizona with on-ramps and off-ramps in Colorado and New Mexico. The 3,500-MW line will span more than 1,200 miles.
Zephyr: a 500-kV HVDC transmission line between Wyoming and Nevada via Idaho. It will span more than 1,000 miles and have a capacity of 3,000 MW.
Overland Transmission: a 500-kV DC transmission line between Wyoming and Idaho will connect with LS Powers’ SWIP line. It will span more than 500 miles and have a capacity of 3,000 MW.
