In Mérida, the capital of Yucatán, temperatures are expected to reach a maximum of 40.3°C and a minimum of 20.7°C on September 1. ^[1] The National Meteorological Service (SMN) forecasts intense heat for the Yucatan Peninsula on Tuesday, September 1, with a high-level atmospheric trough as the primary influence. ^[2] Mexico's state-owned electric utility Comisión Federal de Electricidad (CFE) is preparing new reinforcements for the power system of the Yucatan Peninsula, a region that has experienced blackouts and supply cuts, as reported on 2026-09-01. ^[3] Mexico currently imports approximately 75% of its natural gas from the United States, which serves as the primary fuel source for electricity generation. ^[4] Nearby municipalities to Mérida are expected to experience temperatures ranging between 20°C and 41°C during the central hours of the day on September 1. ^[5] A report cited by the article (El Informe) states that CFE acquired four aeroderivative generation units with a combined capacity of 100 megawatts, which still need to be installed at high-demand points. ^[6] President Claudia Sheinbaum's government has proposed increasing domestic hydrocarbon production to reduce energy dependence, though this does not fully eliminate vulnerability to international price fluctuations. ^[7] The government has committed to a target of reaching 45% renewable energy generation by 2030. ^[8] The PRODESEN agency recognizes that Mexico needs to expand its electrical infrastructure to meet growing demand from industry, the economy, and households. ^[9] Part of the infrastructure intended to increase the reliability of the Yucatan Peninsula power system has not yet entered operation, according to the article. ^[10]
