Mérida II Diesel Power Plant, Mérida, Yucatán, Mexico

Mérida II is a diesel power plant located in Mérida, Yucatán, Mexico. With a capacity of 168 MW, it is a medium-sized facility in the country's power generation sector. The plant is owned and operated by the state-owned utility Comisión Federal de Electricidad (CFE), which manages a significant portion of Mexico's electricity infrastructure. The plant uses oil as its primary fuel, which is common for diesel power plants. Mexico's power generation sector is regulated by the Energy Regulatory Commission (CRE) and the Ministry of Energy (SENER). Environmental oversight is provided by the Federal Attorney for Environmental Protection (PROFEPA). The plant must comply with Mexican Official Standards (NOMs) for emissions, including NOM-085-SEMARNAT-2011 for stationary sources. Mérida II plays a key role in supplying electricity to the Yucatán Peninsula, a region with growing energy demand. Its operation supports grid stability and local economic activity. The plant's location in an urban area necessitates careful management of emissions and noise to minimize impact on surrounding communities.

The plant's use of oil as fuel results in CO2, SOx, and NOx emissions, contributing to local air quality concerns. Its location in Mérida, a populated city, increases potential exposure to pollutants. The facility's age and technology (likely subcritical) may result in lower efficiency and higher emissions per MWh compared to modern combined-cycle plants. Regulatory compliance with Mexican emission standards is essential to mitigate environmental impact.
