On March 12, 2024, the Ministry of Energy (“SENER”) published, on the Official Federal Gazette, the resolution by which it invalidates the decrees that modified the guidelines that established the requirements for the granting of Clean Energy Certificates (“CELS”)1 originally issued by SENER. These decrees allowed the granting of CELS to clean power plants that commenced their operations prior to 2014 -mostly owned by the Federal Electricity Commission- without the need to undertake new investments to increase their clean energy production.
