It’s now official. Monday, Alabama Power Co.’s license to operate its seven Coosa River dams was taken away under terms of a federal court order issued a month ago. The power company will now operate under its prior license.

A power company spokesperson said customers are not affected in any way by the legal issue and no operational changes will take place as it awaits direction from the federal agency that issued the license, the Federal Energy Regulatory Commission.

The unprecedented decision by the U.S. Court of Appeals in Washington, D.C., was a surprise victory for environmentalists and is being followed closely by the hydropower-relicensing industry.
