- EDP Renewables and Salt River Project are developing a 200 MW energy storage system in Coolidge, Arizona, which will begin operating by 2025.
- The project will store and release excess energy during peak demand, helping stabilise Arizona’s power grid and support renewable energy integration.
- Flatland will create 60 construction jobs and two permanent positions and support local businesses while advancing SRP’s efforts to decarbonise its energy portfolio.
EDP Renewables North America and Salt River Project (SRP) have partnered to develop a 200 MW energy storage system near Coolidge, Arizona. The Flatland Energy Storage project will use Tesla’s lithium-ion batteries to reach 200 MW/800 MWh capacity. EDP Renewables plans to make the system operational by 2025.
The system will provide electricity to over 45,000 homes during peak demand. It will store energy during low-demand periods and distribute it during peak times, stabilising Arizona’s power grid and addressing the state’s increasing energy needs.
Battery Energy Storage Systems (BESS) are critical in modernising energy infrastructure and supporting renewable energy integration. Flatland will tackle challenges related to the variability of renewable energy sources, enhance efficiency, and improve grid reliability.
“This is the largest energy storage project in EDP Group’s global portfolio,” said Sandhya Ganapathy, Chief Operating Officer of EDP Renewables North America. “It will accelerate the shift toward renewable energy and boost the U.S. energy grid’s resilience.”
EDP Renewables, SRP, and Meta previously launched the Brittlebush Solar Park, a 200 MW solar facility in Coolidge. Flatland will work alongside the solar park to store and release solar energy as needed, ensuring efficient energy management. Their successful partnership continues to build momentum.
The Flatland system will maximise solar energy output by storing excess electricity and releasing it during peak demand. This project will balance energy supply and demand, allowing better use of renewable energy resources and stabilising the grid.
In addition to environmental benefits, Flatland will create jobs and economic opportunities. The project will generate 60 jobs during construction and provide two permanent positions for operations. EDP Renewables also plans to engage local small businesses throughout the development process.
Bobby Olsen, SRP’s Deputy General Manager, emphasised the importance of the project in reducing carbon emissions. “This project aligns with our broader goal of increasing the share of renewable energy for our customers and decarbonising our energy portfolio,” he said.
Flatland will support SRP’s long-term strategy to provide cleaner energy and reduce the company’s carbon footprint. The project will improve grid reliability sustainably, addressing Arizona’s growing electricity demands.
EDP Renewables and SRP’s partnership reflects a broader push in the energy industry to integrate more renewable sources while enhancing grid performance. Flatland stands as a critical achievement in advancing that effort.
Flatland represents a crucial step toward Arizona’s more sustainable energy future with its advanced technology, local economic benefits, and environmental impact. The project illustrates how energy storage systems can drive the transition to a more reliable, renewable-powered grid.
