The AES Corporation was selected by Arizona Public Service to deliver a 100 MW, four-hour duration battery-based energy storage system. The project, owned and operated by AES, will provide critical peaking capacity and operational flexibility, enabling the efficient use of renewable energy, lowering costs and emissions, and providing increased reliability for APS’ customers.

Under a 20-year agreement, AES will provide APS with the storage capabilities powered by Fluence’s proven Advancion platform. The project will contribute to a more sustainable energy future for Arizona through the integration of more renewables in the state’s energy mix.
“Arizona is realizing its great solar potential. As the state continues its transition to more sustainable energy sources, customers will require cost-effective and reliable electricity,” said Andrés Gluski, AES President and Chief Executive Officer. “Energy storage can replace traditional peaking thermal generation to meet peak power demands while reducing greenhouse gas emissions and maximizing the use of renewable energy.”
The ability for batteries to absorb and discharge power has great value for regions pursuing high levels of renewable energy, such as Arizona. The storage system will collect energy when the sun is shining and then give it back during peak hours when its capacity is needed most by customers. By releasing solar energy when it has traditionally been unavailable, customers will have continuous access to a cleaner, more reliable energy mix.
“By delivering solar after sunset, these projects with AES signal a new direction for how we can meet our customers’ peak need for energy with an increasingly clean mix of resources,” said Brad Albert, Vice President, Resource Management for APS.
This partnership is part of APS’s plan to add nearly one GW of clean energy projects by 2025. The new 100 MW energy storage system is expected to begin operations in June 2021.
