Gral. Agustín Olachea A. (Puerto San Carlos) - 104.1 MW Diesel Power Plant in Baja California Sur, Mexico

Gral. Agustín Olachea A. (Puerto San Carlos) is a diesel power plant located in Baja California Sur, Mexico. With a capacity of 104.1 MW, it is a medium-sized facility within Mexico's power generation sector, serving the energy needs of the surrounding area. The plant is owned and operated by the state-owned utility CFE. The plant operates on oil as its primary fuel, a common choice for diesel power plants in remote or island regions. In Mexico, such facilities are subject to national emission standards, including those set by the Secretaría de Medio Ambiente y Recursos Naturales (SEMARNAT). The technology typically involves internal combustion engines, which offer flexibility for peaking power but have higher emissions per MWh compared to combined-cycle gas turbines. As part of CFE's generation fleet, this plant plays a role in ensuring grid stability and meeting local demand in Baja California Sur, a region with limited interconnection to the mainland grid. Its operation contributes to the area's energy security, though the use of oil-based fuel implies a higher carbon footprint relative to natural gas or renewable sources.

The plant's use of oil as primary fuel results in significant CO2, SOx, and NOx emissions per MWh compared to natural gas or renewable sources. Located in Baja California Sur, a region with sensitive coastal and marine ecosystems, emissions may affect local air quality. The facility's age and technology (diesel engines) typically have lower efficiency than modern combined-cycle plants, increasing its environmental footprint. Proximity to populated areas could amplify health impacts from particulate matter and other pollutants.
