In January 2021, certain entities achieved the status of Exempt Wholesale Generators, as per the regulations of the Federal Energy Regulatory Commission. This change in status is outlined in the Commission's regulations found in 18 CFR 366.7(a) (2020). The notice was officially documented by Nathaniel J. Davis, Sr., the Deputy Secretary, and was filed on February 16, 2021.
Simple Explanation
Some companies got a special permission to make and sell electricity without having the same rules as others. This happened in January 2021, and it's like getting a special badge saying they can do this.
