GridStor acquires key battery energy storage projects in Arizona and Oklahoma to meet growing power demands

GridStor, a leading developer and operator of utility-scale battery energy storage systems (BESS), has announced the acquisition of two significant projects designed to address rising electricity demands and enhance grid reliability. The company acquired a 100 MW / 400 MWh project in Arizona from Capacity Power Group and a 200 MW / 800 MWh project in Oklahoma from Black Mountain Energy Storage.

These acquisitions mark a major step forward for GridStor, which is backed by Goldman Sachs Asset Management, as it continues to invest in energy infrastructure that supports the growing demand for reliable and clean power across the United States.

How Will GridStor’s Battery Projects Address Arizona’s Energy Challenges?

Arizona is experiencing unprecedented electricity demand due to rapid residential growth and the expansion of industrial operations. This surge has increased the strain on local utilities, prompting a need for scalable, near-term energy solutions.

The Arizona battery energy storage project, acquired from Capacity Power Group (CPG), is expected to play a vital role in stabilizing the state’s grid. Battery storage systems offer a flexible solution, delivering power during peak demand hours and ensuring a consistent energy supply.

Chris Taylor, CEO of GridStor, highlighted the importance of this acquisition, stating, “Battery storage is a scalable and near-term solution to powering historic load growth in Arizona. Every day, batteries across the state are consistently providing energy to stabilize the power system and meet hours of greatest demand. This acquisition demonstrates GridStor’s commitment to supporting Arizona in meeting the growing power needs of its residents and businesses.”

For CPG, the project represents a shared commitment to clean energy. Charly Bray, Principal at Capacity Power Group, noted, “We’re excited to work with GridStor to build reliable energy solutions that provide affordable clean capacity to the electrical grid.”

Arizona’s transition to battery energy storage is part of a broader strategy to integrate renewable energy sources, such as solar power, into its grid. The state’s climate and geographic location make it a prime candidate for solar energy, and battery storage will be essential to store excess generation and release it during times of peak demand.

Why Is Battery Energy Storage Crucial for Oklahoma’s Power Grid?

Oklahoma is another key region where electricity demand is surging, driven by the development of data centers and other industrial facilities. The Southwest Power Pool (SPP), which manages the regional grid, has warned of the need for new power resources to maintain system reliability.

GridStor’s acquisition of the 200 MW / 800 MWh Oklahoma project from Black Mountain Energy Storage (BMES) addresses this critical need. Located in Eastern Oklahoma, the project will be developed in two phases and will provide reliable power to support both industrial and residential needs.

“Battery storage is a scalable and near-term solution to provide reliability to the SPP system and its large customers,” said Taylor. “Batteries provide energy to stabilize the power system and meet hours of greatest demand every day in multiple regions across the U.S. This acquisition demonstrates GridStor’s commitment to rapidly adding battery energy storage to the SPP grid to support the growing needs of its residents and businesses.”

BMES shares GridStor’s vision of addressing grid challenges with innovative solutions. Witt Duncan, Chief Commercial Officer of Black Mountain Energy Storage, stated, “Together with GridStor, we’re building reliable, affordable, and sustainable energy solutions today for a promising tomorrow.”

Once operational, the Oklahoma project will strengthen grid resilience by providing consistent power through participation in the SPP-managed electricity market. This initiative aligns with the increasing demand for clean energy in the Midwest, where renewable sources like wind power are abundant but require complementary storage solutions to ensure grid reliability.

What Does GridStor’s Expansion Mean for the Future of Energy Storage?

With the acquisition of these two major projects, GridStor continues to solidify its position as a leader in the U.S. battery energy storage market. The company’s strategic focus on regions experiencing rapid energy demand growth ensures that its projects have an immediate and lasting impact on grid stability.

GridStor’s backing by Goldman Sachs Asset Management provides the financial strength and expertise needed to scale its operations and develop cutting-edge energy storage solutions. Its team of seasoned energy professionals has a proven track record in clean energy project development, financing, and operations.

These latest acquisitions are part of a broader trend toward the adoption of battery energy storage across the U.S. As utilities strive to meet renewable energy goals and mitigate the effects of climate change, battery storage is emerging as a critical component of the nation’s energy infrastructure.

The Path Forward: Scaling Clean and Reliable Energy Solutions

GridStor’s projects in Arizona and Oklahoma underscore the growing importance of battery energy storage in addressing regional energy challenges. By investing in scalable, clean energy infrastructure, GridStor is helping pave the way for a more sustainable and resilient power grid.

As energy demands continue to rise, GridStor remains committed to its mission of delivering innovative solutions that bridge the gap between renewable energy generation and reliable power supply.
