Officials with Alabama Power said the company will develop the state’s first utility-scale battery energy storage system (BESS) at the site of the former coal-fired William Crawford Gorgas Electric Generating Plant.
The original power plant, best known as Plant Gorgas, was built in 1917 and was in service until 2019. The facility prior to being closed featured three units, with 1,000 MW of total generation capacity. The plant, located in Walker County, Alabama, at the time of its closure was the oldest coal-burning power plant in the state.
The new Gorgas Battery Facility will store up to 150 MW of electricity that will be generated by other Alabama Power resources.
“This facility will help Alabama Power understand how we can best use battery systems on our electric grid so that customers have power when they need it,” said Jeff Peoples, Alabama Power chairman, president and CEO, in a statement on March 3. “The project honors Plant Gorgas’ legacy, which has played a significant role in powering the state of Alabama since 1917.”
The 7-acre BESS facility will be designed as a standalone system. It will connect to and charge directly from the electric grid. Construction of the system is expected to begin this year and be completed within the next two years. Officials on Monday said the system will use lithium iron phosphate batteries with a two-hour duration. The batteries will be able to fully recharge in just more than two hours.
“Batteries can charge when energy costs are lower and discharge when energy costs are higher, helping keep costs down. They can also supply energy to our system quickly in response to changing conditions,” said Brandon Dillard, senior vice president of Generation for Alabama Power. “We are excited to learn how battery storage technology best fits into our system to reliably serve our customers.”
The utility in a news release said that the batteries “also have the potential to help integrate additional clean energy resources into the company’s generation mix, providing complimentary technology for variable, weather-dependent resources, like solar.”
“As we work to make our system stronger and smarter, innovative technologies such as battery storage could help ensure a steady energy supply,” Dillard said. Officials said the decision to reuse the retired Plant Gorgas site—the original coal-fired power plant was demolished by implosion in September 2021—supports the utility’s focus on sustainable solutions that reinforce its community commitment.
“Plant Gorgas and Walker County hold a special place in our company’s history,” said Jill Stork, vice president of Western Division for Alabama Power. “The reuse of this site reaffirms our support of the communities we have long served, ensuring sustainable solutions that honor our past while looking to the future.”
