Sundance Project
aps
Project description
The Sundance Power Plant, located 55 miles southeast of Phoenix near Coolidge, is a key component of our energy infrastructure. APS proposes to add two additional natural gas units at Sundance – adding 90 megawatts (MW), enough energy to serve an additional 14,400 Arizona homes. We expect construction to begin in late 2024, with the two units in service spring 2026.
Project need
There is significant growth in demand for energy in our service territory, and we are preparing to meet nearly 40% load growth by 2031. These new units will provide much-needed energy during the late-afternoon and evening hours, when customer energy use is highest. We are committed to providing reliable and affordable service and use a rigorous selection process and detailed analysis to determine the best combination of resources to serve customers. Our natural gas fleet is an important part of a diverse energy mix and a critical partner to the large quantities of solar and battery energy storage we’re adding to our system.
These new units are necessary to support the reliable service our customers count on. Modern natural gas units, like those planned for this location, provide flexible, on-demand energy when customers need it most. Adding additional units at Sundance maximizes the current infrastructure and gas pipeline capacity to generate reliable energy for Arizona.Project Vicinity
