CPS Energy and Quidnet Energy today announced a 15-year commercial agreement for an energy storage project employing Quidnet's Geomechanical Pumped Storage (GPS) technology.
The project will be developed in two phases, starting with an initial one-megawatt (MW), 10-hour storage facility.
CPS Energy has partnered with Quidnet under a 15-year agreement that will allow time for both parties to explore this type of technology. CPS Energy will have the option to expand the project to provide 15 MW as the project matures.
"Quidnet's innovative GPS energy storage technology pumps water underground and stores it between impermeable rock layers. The rock performs like a natural spring and holds the water under pressure. When the project is called upon to supply electricity, the pressurized water is released to power a hydroelectric turbine that generates emission-free electricity. The entire process is closed loop to conserve water resources," the companies said
Previously, Quidnet developed Texas energy storage test sites in Medina and San Saba Counties. It is working on pilot projects in Ohio, New York, and Alberta, Canada. The company is backed by Breakthrough Energy Ventures, Evok Innovations, Trafigura, and other investors
