Punta Prieta II Diesel Power Plant, Baja California Sur, Mexico

Punta Prieta II is a diesel power plant located in Baja California Sur, Mexico, with a capacity of 112.5 MW. Operated by the state-owned utility CFE, it is one of several power generation facilities serving the Baja California Sur region. The plant plays a key role in meeting local electricity demand, particularly in an area with limited grid interconnection. The plant uses oil as its primary fuel, a common choice for diesel power plants. In Mexico, power generation 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). Diesel plants like Punta Prieta II are subject to emissions standards for SOx, NOx, and particulate matter, though specific compliance details are not publicly available. As part of CFE's generation fleet, Punta Prieta II contributes to the stability of the Baja California Sur isolated grid. Its location near La Paz supports the region's growing energy needs. The plant's operational status and capacity make it a significant asset for local power supply, though its reliance on oil places it within the context of Mexico's broader energy transition efforts.

Punta Prieta II, as an oil-fired diesel plant, emits CO2, SOx, NOx, and particulate matter. Its location in Baja California Sur, a region with sensitive coastal ecosystems and growing tourism, means emissions may affect local air quality. Older diesel plants typically have lower efficiency and higher emissions per MWh. Proximity to populated areas could increase local health impacts.
