Massive Alabama solar project shines light on Walmart

One of Alabama’s largest solar energy facilities, built in partnership with utility Alabama Power, is now helping power one of the country’s largest retailers.
The 72 MW Alabama Solar A project sits on 1,400 acres of in Chambers County, just south of LaFayette. Seventy-two megawatts is an amount of energy equivalent to what is typically needed to power about 18,000 homes, according to Alabama Power.
Most of the renewable energy attributes from Alabama Solar A are going to serve Walmart through a long-term contract to help the retailer meet its renewable energy goals. Alabama Power is marketing the remaining energy and renewable energy attributes from the project to other customers interested in supporting new renewable generation in the state.
The project is operated by Boise, Idaho-based Clenera and was built by Swinerton Renewable Energy, based in San Diego. Alabama Power has a long-term power purchase agreement with the primary owner of the facility, Houston-based Centaurus Renewable Energy, to receive all the energy and environmental attributes from the solar farm, which it can then use for its own customers or resell to others – as in the contract with Walmart.
The long-term agreements make the project cost-effective for Alabama Power customers, while also supporting Walmart, officials said.
“This project is great for Alabama Power customers because it puts downward pressure on rates. It also helps our partner, Walmart, meet its sustainability goals. And it supports the local economy in Chambers County. It’s a win-win-win,” said John Kelley, Alabama Power’s director of forecasting and resource planning.
Work started in February on the $140 million project, which began generating electricity at year’s end. More than 450 people were employed at the site during peak construction, many of them local workers.
The facility’s permanent employees also are being hired locally.
The site uses more than 338,000 solar panels that automatically track the sun for optimum efficiency. About 57,000 pilings were installed in 4,000 rows to create the solar energy facility.
The project was built with sensitivity to the environment in mind. Detention ponds capture rainwater, helping prevent erosion and protecting water quality. Tree stumps removed during construction were ground into mulch and used across the site to also prevent erosion, until grass planted throughout the facility had a chance to sprout and grow.
Alabama Solar A is the third solar project connected to Alabama Power to begin operating in 2017. Alabama Power also previously unveiled company-owned solar facilities on two of the state’s military bases, Anniston Army Depot and Fort Rucker. The company also has rights to the generation from two wind farms in the Midwest and markets the renewable energy attributes from all these projects to interested parties. Alabama Power also produces clean, renewable hydropower at 14 hydroelectric facilities on the Coosa, Tallapoosa and Black Warrior rivers.
