The project will use Fluence’s advanced Gridstack Pro 5000™ energy storage solution with delivery expected in early 2027.
Located alongside two 80 MW solar arrays, the Winchester project will deliver a total of 160 MW / 640 MWh of energy storage capacity across two identical systems. Once operational, the project will support grid balancing and forecasted load growth for the region as well as support economic development and local infrastructure investment for Cochise County, AZ.
The Gridstack Pro 5000 solution will include domestically manufactured enclosures, inverters, and thermal management systems to enable the full solar-plus-storage facility to qualify for domestic content tax credits, while supporting U.S. manufacturing and American energy security.
“We’re proud to partner with Torch Clean Energy on the Winchester project and to bring this important power resource to the Arizona electric grid,” said John Zahurancik, President, Fluence Americas. “This facility is a great step toward ensuring affordable, reliable, and secure power for the local community and will support regional economic activity and expected load growth for many years to come.”
“Torch is excited to partner with Fluence to manufacture the energy storage system for our Winchester project,” said Travis Haggard, President of Torch Clean Energy. “The Gridstack Pro 5000 will allow us to shift cost-effective solar generation to be dispatched when the grid needs it most.”
With more than 22 GWh of battery energy storage capacity deployed or contracted across 90+ projects in the United States, Fluence is supporting leading U.S. utilities, power producers, and developers with cutting-edge storage solutions that enable a more reliable and cost-effective grid.
