Alabama’s first grid-scale battery storage project is taking shape in Walker County, marking a step forward in the state’s energy infrastructure. The Gorgas Battery Energy Storage System is being constructed on the site of the former coal-fired Plant Gorgas, which operated for more than a century before being retired. The project repurposes the historic coal plant location into a modern energy asset and is intended to support grid reliability for Alabama Power by storing electricity for dispatch during periods of high demand.
Over the past year, the project has moved from early site work to full-scale installation. Tesla Megapacks began arriving at the seven‑acre site in early February, with all 92 units expected to be on site soon. These Megapacks will link through 46 medium‑voltage transformers and a dedicated control house before connecting to Alabama Power’s high‑voltage network via a new switchyard.
According to construction manager Cameron Key, the system draws power from Alabama Power’s transmission network during periods of low demand, storing it for later use when consumption peaks.
Once fully commissioned, the Gorgas BESS will provide 150 MW of storage capacity, enough to supply about 9,000 homes for two hours under typical conditions. The batteries are designed to reach a full charge in just over two hours, allowing the system to absorb surplus generation when demand is low and discharge during peak load events.
Assistant site manager Jonathan Watts described the project as a fundamental shift in how the company balances supply and demand. “The Gorgas BESS facility provides Alabama Power customers affordability, reliability and a sustainable option for their power,” he said.
Each Megapack houses 24 battery modules, bringing the site total to 2,208 modules.
Beyond the technical achievement, Gorgas BESS reflects Alabama Power’s effort to repurpose legacy energy sites for modern use. By converting the retired Gorgas plant into a clean energy asset, the company is preserving local history while positioning itself for a lower‑carbon future.
Once operational, the Gorgas BESS is expected to serve as a resource for grid management and as a demonstration of how utility-scale batteries can support reliability, cost management, and renewable integration across the service area.
