Arizona just took a giant leap toward a cleaner and more reliable energy future. D. E. Shaw Renewable Investments (DESRI), a leading developer of renewable energy assets in the United States, has officially broken ground on a major new project: a 205-megawatt (MW) solar photovoltaic facility paired with a massive 1-gigawatt-hour (GWh) battery energy storage system. The project, located in Pinal County, Arizona, is expected to play a key role in strengthening the state’s electric grid while supporting its clean energy goals.
This development, once completed, will be among the largest solar-plus-storage installations in the state and is a strong signal of continued investment in the American Southwest’s renewable energy landscape.
What is the DESRI Project About?
The project is named Edison East Energy Center and is strategically positioned to take advantage of Arizona’s vast solar resources. The 205 MW solar farm will generate enough electricity to power tens of thousands of homes, while the 1 GWh battery system will store excess solar power for use when the sun isn’t shining — helping to stabilize electricity supply during peak hours or emergencies.
According to DESRI, this hybrid project will deliver clean energy under long-term power purchase agreements (PPAs) with two major off-takers — including Arizona Public Service Company (APS), the state’s largest electric utility.
DESRI emphasized that this combination of solar power and battery storage will support grid reliability, renewable integration, and emission reductions across the state. The project is expected to become operational by 2026.

Why Arizona?
Arizona has become a hotbed for solar development, thanks to its abundant sunshine, growing energy needs, and increasing commitment to climate action. As part of its broader goals to decarbonize, the state is pushing utilities and developers to invest in cleaner alternatives.
The Edison East Energy Center is a reflection of that shift. According to Matt Murphy, Chief Operating Officer at DESRI, Arizona’s solar profile and regulatory support make it an ideal location for hybrid energy projects.
“Our team is proud to partner with Arizona to bring this forward-thinking project to life. Combining solar energy with battery storage allows us to deliver dependable, renewable energy to the grid, even when the sun goes down,” Murphy said during the groundbreaking ceremony.
Economic and Environmental Benefits
Besides reducing greenhouse gas emissions, the project is expected to bring significant economic benefits to the region. It will generate hundreds of construction jobs, with a strong focus on hiring local workers and contractors.
Once operational, the Edison East Energy Center will also contribute tax revenue to local schools, infrastructure, and public services in Pinal County. It’s a win-win — supporting the local economy while helping the state reach its environmental goals.
Moreover, battery storage like this helps cut down on the use of fossil fuel peaker plants — which are typically turned on during times of high demand and are more polluting than base-load power sources.

Strong Public and Private Collaboration
The success of the DESRI project is largely credited to effective collaboration between public agencies, private developers, and utility companies. DESRI has a solid track record of delivering complex renewable energy projects and partnering with community stakeholders to ensure responsible development.
This project is no exception. DESRI worked closely with local officials, environmental consultants, and tribal representatives to ensure the project respects local ecosystems and communities.
Notably, the project includes an environmental management plan that protects native habitats and integrates sustainable construction practices.
A Bigger Picture for DESRI
For DESRI, this groundbreaking is part of a larger mission. The company has developed over 6 GW of renewable energy capacity, including solar, wind, and storage projects across the U.S. It continues to grow its clean energy portfolio as the nation looks to reduce its dependence on fossil fuels.
With this Arizona project, DESRI expands its footprint in the southwestern U.S., where solar and storage are rapidly becoming core components of energy infrastructure.

What’s Next?
Construction on the Edison East Energy Center is expected to continue through 2025, with the project going live by early 2026. During this period, DESRI and its partners will focus on workforce development, community engagement, and system integration with Arizona’s utility grid.
Once operational, the combined power of 205 MW solar and 1 GWh storage will serve as a model for future renewable energy systems — where solar power is no longer limited to daylight hours but can be tapped at any time.
As the U.S. continues to navigate energy transition and grid modernization, projects like this one will be vital to building a sustainable, resilient, and affordable power system.
Final Thoughts
Arizona’s landscape is known for its sun and deserts — and now, it’s becoming known for clean energy leadership. The DESRI solar + storage project not only puts Arizona on the renewable energy map but also sets an example for other states to follow.
With strong partnerships, forward-looking investments, and a commitment to sustainability, this project is a powerful step forward in America’s clean energy journey.
