Plutarco Elías Calles (Petacalco) Coal Power Plant, Guerrero, Mexico

Plutarco Elías Calles (Petacalco) is a major coal-fired power plant located near the Pacific coast in Guerrero, Mexico. With a capacity of 2,778.4 MW, it ranks among the largest coal power stations in Mexico and Latin America. The plant is owned and operated by the state-owned utility Comisión Federal de Electricidad (CFE), playing a key role in the country's energy mix. The plant utilizes coal as its primary fuel and employs conventional steam turbine technology typical of large-scale coal facilities. Given its size and age, the plant likely operates under Mexico's national emission standards, which align with international best practices for SOx, NOx, and particulate matter control. The plant's coastal location facilitates fuel delivery via maritime routes, a common logistical advantage for large coal plants. As a baseload power source, Petacalco contributes significantly to grid stability in western Mexico. However, its coal-fired operation results in substantial CO2 emissions, making it a focal point for discussions on Mexico's transition to cleaner energy sources. The plant's proximity to the Pacific Ocean and nearby communities underscores the importance of stringent environmental monitoring and compliance with local regulations.

The plant's coal combustion produces significant CO2, SOx, NOx, and particulate emissions, contributing to local air quality concerns and regional greenhouse gas inventories. Its coastal location near the Pacific Ocean may affect marine ecosystems through thermal discharge and potential ash runoff. The surrounding region of Guerrero is ecologically diverse, with tropical dry forests and coastal habitats, making emission controls critical for minimizing ecological impact.
