DIESEL TAMAYA (SUTA) - 99 MW Oil-Fired Diesel Power Plant in Tocopilla, Chile

DIESEL TAMAYA (SUTA) is an operational oil-fired diesel power plant located in the Antofagasta Region of Chile, near the coastal town of Tocopilla. With a capacity of 99 MW, it is a medium-scale facility within Chile's power generation sector, which relies heavily on thermal and renewable sources. The plant is owned and operated by E-CL, a major energy company in the region. The plant uses diesel (oil) as its primary fuel, a common choice for peaking and backup power in Chile's northern grid. Diesel plants like this one are typically used to meet demand spikes or provide grid stability, especially in areas with high mining activity. The facility's technology is based on internal combustion engines, which offer rapid start-up and flexibility but have higher fuel costs and emissions compared to combined-cycle gas turbines. Environmentally, the plant's oil-fired operation results in significant CO2, SOx, and NOx emissions per MWh, contributing to local air quality concerns. Its location in a coastal desert area with low population density reduces direct exposure, but the plant's emissions still impact the regional environment. The facility plays a key role in supporting Chile's mining sector, which requires reliable power for extraction and processing operations.

The plant's oil-fired combustion produces substantial CO2, SOx, and NOx emissions, contributing to greenhouse gas levels and local air pollution. Located in the Atacama Desert, the region's arid climate and limited vegetation reduce natural pollutant dispersion, potentially affecting nearby communities and ecosystems. The facility's age and technology (likely subcritical diesel engines) further increase its environmental footprint compared to modern combined-cycle or renewable alternatives.
