Construction is underway on the 300-MW solar and 1,200-MWh storage Pioneer Clean Energy Center in Arizona. The project is developed by BightNight and partner Cordelio Power and will feature Fluence Energy Gridstack Pro BESS.
“Pioneer will deliver reliable, dispatchable clean power that Arizona needs to support its rapid growth,” said Martin Hermann, CEO of BrightNight. “This project demonstrates how large-scale renewables paired with advanced storage can provide firm capacity and real grid resilience. We are pleased to work with partners who share our commitment to building the next generation of energy infrastructure.”
Fluence’s Gridstack Pro solution will incorporate U.S.-manufactured cells, modules, enclosures, and thermal management systems, supporting the advancement of domestically produced energy storage technology while strengthening American energy security.
“We first put storage on the U.S. grid to meet exactly the kind of reliability needs Arizona is facing, and we have since proven that it can be delivered at massive scale,” said John Zahurancik, Chief Customer Success Officer, Fluence. “We are proud to partner on this project, demonstrating that U.S.-made battery systems can meet critical power needs reliably and cost-effectively.”
Arizona Public Service (APS), the largest electricity provider in Arizona, has signed a PPA for the full power produced and stored by the Pioneer Clean Energy Center. Commercial operation expected by April 2027.
