- Owner: Alabama Power
- Parent Company: Southern Company
- Plant Nameplate Capacity: 1,416.7 MW (Megawatts)
- Units and In-Service Dates: Unit 6: 125.0 MW (1951), Unit 7: 125.0 MW (1952), Unit 8: 187.5 MW (1956), Unit 9: 190.4 MW (1958), Unit 10: 788.8 MW (1972)
- Location: 460 Gorgas Rd., Parrish, AL 35580
- GPS Coordinates: 33.645028, -87.19875
- Technology: Subcritical (Units 6-9), Supercritical (Unit 10)
- Coal type: Bituminous
- Coal Consumption:
- Coal Source: Blended Alabama coal from multiple mines (Alabama Coal)
- Number of Employees:
- Unit Retirements: Units 6 & 7 retired in August 2015, Units 8-10 retired in April 2019.
In August 2014, Alabama Power announced that they will retire units 6 & 7 at the Gorgas facility ahead of the Mercury and Air Toxics Standards 2015 compliance date. The two units were retired in August 2015.
Units 8, 9 and 10 were retired in April 2019.
Alabama Power spent more than US$400 million at the plant since 2010 on environmental upgrades, in efforts to keep the plant -- which has been in operation since 1917 -- in compliance with tightening federal environmental laws, including the U.S. Environmental Protection Agency's MATS (mercury and air toxics standards) rule, meant to limit the amount of mercury emitted to the air at coal-fired power plants.
The company invested US$375 million in a “baghouse” at the plant for units 8, 9 and 10, a massive system of air filters meant to remove mercury from the plant’s air emissions, which was scheduled for completion by the end of 2015.
Critics like the Southern Alliance for Clean Energy said the power company was spending too much money on keeping old coal plants in operation rather than exploring alternatives. According to AL.com, Alabama Power customers will be repaying about US$740 million in costs related to the plant long after it closes, according to documents filed with the Securities and Exchange Commission, coming out to about US$500 for each customer.
Fire Retardant Compound Spil
On March 26, 2019, Alabama Power Company officials told environmental regulators that the company spilled about 700 gallons of a fire retardant compound near its Gorgas Steam Plant on March 23, 2019 - a few days before about 100 dead fish were seen floating on the river nearby. The incident happened after the primary fire control system lost air pressure and a backup system failed to activate.

Coal Waste Site
Gorgas ranked 7th on list of most polluting power plants in terms of coal waste
In January 2009, Sue Sturgis of the Institute of Southern Studies compiled a list of the 100 most polluting coal plants in the United States in terms of coal combustion waste (CCW) stored in surface impoundments like the one involved in the TVA Kingston Fossil Plant coal ash spill. The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.
Gorgas Steam Plant ranked number 7 on the list, with 2,888,290 pounds of coal combustion waste released to surface impoundments in 2006.
Carbon Capture and Storage research
In June 2010 the University of Alabama announced that it had "been awarded a U.S. Department of Energy grant totaling more than $4.85 million for a multidisciplinary project that will characterize geologic formations for carbon dioxide storage in Alabama". The project aims to "define an estimated 28 gigatons of carbon dioxide storage capacity underlying northwest Alabama". The funds originated from the American Recovery and Reinvestment Act. UA News reported that the project will "investigate the possibility for storage in an underground reservoir in the vicinity of the Alabama Power Gorgas Steam Plant. Successful completion of the project has the potential to extend the useful life of coal-fired power plants throughout the region. By investigating the geology near existing power plants, transportation costs to a carbon dioxide storage area would be greatly reduced." Other groups involved in the project are the Alabama Geological Survey and Rice University and industry co-funders are Alabama Power and Southern Company.
