Rocky Mountain Power has announced changes to its planned transmission line that will run between the Windstar and Aeolus substations in eastern Wyoming.
First, the proposed eastern 230 kV transmission line will be removed from the Gateway West plan. The company is also dropping all eastern routes from further consideration.
The determination that the second 230 kV line was no longer needed came from continued assessment of the transmission project objectives, the availability of resources throughout the company's system and finding the best balance between cost and risk for customers, Rocky Mountain Power says.
Development will continue to move forward on the planned 230 kV line to the west (known as the 1W route), running parallel to the existing 230 kV line.
As originally planned, the existing 230 kV line will be rebuilt between the existing Windstar substation near Glenrock, Wyo., and the new Aeolus substation to be built near Medicine Bow, Wyo., the company explains.
"The need for electricity for our customers continues to grow in the company's six-state service area, and the Gateway West transmission project will help provide for that need," says Rita Meyer, vice president at Rocky Mountain Power. "The company's purpose and need for this project is to provide safe, reliable and reasonably priced electricity to meet the needs of customers. The changes announced today do not detract in any way from that objective."
