Mérida III Gas Power Plant, Yucatán, Mexico | 484 MW Capacity

Mérida III is a gas-fired power plant located in Yucatán, Mexico, with a capacity of 484 megawatts. The plant is owned and operated by CFE/PIE, a subsidiary of the state-owned Comisión Federal de Electricidad (CFE). As a medium-scale gas power plant, it plays a key role in meeting the electricity demand of the Mérida metropolitan area and the broader Yucatán Peninsula. The plant operates on natural gas, a fuel with lower CO2 emissions compared to coal or oil. While specific technology details (e.g., combined cycle or simple cycle) are not disclosed, gas plants in Mexico often utilize combined cycle technology for higher efficiency. The facility is subject to Mexican environmental regulations, including the General Law of Ecological Balance and Environmental Protection (LGEEPA) and emissions standards set by the Ministry of Environment and Natural Resources (SEMARNAT). Mérida III contributes to the region's energy security and supports economic activities in Yucatán, including tourism, manufacturing, and services. Its location near the city of Mérida ensures efficient power distribution to residential, commercial, and industrial users. The plant's operation aligns with Mexico's energy transition goals, as natural gas serves as a bridge fuel toward cleaner energy sources.

The plant's use of natural gas results in lower emissions of sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter compared to coal-fired plants. However, CO2 emissions remain a concern, contributing to climate change. The facility is located near Mérida, a city with over 1 million inhabitants, so air quality impacts are relevant. Modern gas plants often incorporate emissions control technologies, and regulatory oversight by SEMARNAT ensures compliance with ambient air quality standards.
