The Energy and Gas Regulatory Commission (CREG) established a temporary energy savings program that began on September 1, 2026, in the municipalities of Melgar and Carmen de Apicalá in the Tolima department of Colombia. ^[1] The Comisión de Regulación de Energía y Gas (CREG) established a new energy savings program effective September 1, 2026, with an initial validity of six months to address conditions caused by the El Niño phenomenon. ^[2] The program aims to incentivize efficient electricity use and protect national water reserves due to conditions associated with the El Niño phenomenon. ^[3] The surcharge rates are 30% for Strata 1, 2, and 3; 50% for Strata 4, 5, and 6; and 70% for commercial and industrial users. ^[4] Users who maintain consumption between 90% and 110% of their target will continue with standard billing, while those exceeding 110% will face a surcharge only on the excess kilowatt-hours. ^[5] The CREG resolution, numbered 101 120 of 2026, excludes all municipalities in the Valle del Cauca served by Celsia from the program due to the emergency caused by the earthquake on August 10. ^[6] The program includes a temporary additional charge for excess consumption, calculated at 30% for strata 1-3, 50% for strata 4-6, and 70% for commercial and industrial clients. ^[7] The program sets individual consumption targets based on a user's history from the last 12 months, with additional charges applied only if consumption exceeds the target by more than 10%. ^[8]
