Gridflex Energy LLC, a developer of bulk energy-storage projects, is pursuing plans for five pumped storage hydroelectric projects in Wyoming. Four of the proposed projects would be located in Carbon County, within range of several planned transmission projects intended to ship Wyoming's wind energy to Southwestern markets.
The transmission lines include the Zephyr line, the TransWest Express and the Overland transmission project. Rocky Mountain Power's Gateway West is another major new line that would move wind energy westward.
The fifth proposed pumped storage project would be located in Converse County, near the planned origination point of the High Plains Express, which is intended to help deliver renewable energy through Wyoming, Colorado and New Mexico to Arizona.
The pumped storage projects range in size from 300 MW to 500 MW; the combined capacity of the projects, if all were developed, would be 1,900 MW. Energy storage potential would be more than 50 GWh – equivalent to what 3,000 MW of wind turbines would put out for 17 hours at their maximum.
Gridflex is pursuing partnerships with a number of wind and transmission developers.
