A 2025 PLMA Award of Excellence winner, APS marked five years of commitment to 100% clean electricity by 2050 and to date has achieved 54% clean energy. By collaborating with its customers, APS has supported its clean energy goal by operating one of the largest VPPs in North America. 

With its VPP, APS can shift load using behind-the-meter resources to achieve predetermined load shapes during flexibility events. Given Arizona’s extreme temperatures, APS plans to continue refining and testing new use cases for dynamic load shaping. With its demand growth increasing to >13,000 MW of energy by 2038, the utility is also committed to building more customer-collaborative VPP solutions to address extreme weather, congestion, renewable generation variability, and rising energy costs.
