Alabama Power will build a 150-MW battery storage system at the former site of a power plant

Utility Southern Co’s Alabama unit announced on Monday that it would develop a utility-scale, battery energy storage system of 150 megawatts (MW) at the former site of its coal-fired plant in Walker County.

CONTEXT

The new Gorgas Battery Facility is designed to house lithium-ion phosphate battery packs with a 2-hour lifespan. Construction should begin in this year, and be finished by 2027.

Alabama Power said that the seven-acre facility would be designed as an independent system, which will be connected to and charged directly from electric grid.

Why it's important

BESSs have become increasingly important as companies and countries move to cleaner energy in order to combat climate changes.

The systems are able to store excess energy from renewable sources. This can be very useful when there is a high demand for energy or if power production is low.

Batteries can be used to integrate clean energy sources into a company's mix of power generation. They are a complementary technology that complements variable and weather-dependent renewable resources such as solar.

KEY QUOTE

Batteries can be charged when energy prices are low and discharged when energy rates are high, which helps to keep costs low. "They can supply energy quickly to our system in response to changing circumstances," said Brandon Dillard. Senior vice president of Alabama Power’s generating fleet.
