Extra Caraguatatuba Diesel Power Plant, Caraguatatuba, Brazil

Extra Caraguatatuba is a small-scale diesel power plant located in Caraguatatuba, Brazil. With a capacity of 2.72 MW, it serves local energy needs in the coastal region of São Paulo state. The plant operates on oil fuel, typical for diesel power plants in remote or backup applications. As a diesel power plant, Extra Caraguatatuba operates under Brazil's national environmental regulations, including CONAMA resolutions for air quality and emissions. Diesel plants in Brazil are subject to limits on SOx, NOx, and particulate matter, and may require environmental licenses from CETESB in São Paulo state. The plant's small capacity suggests it may serve as a peaking or emergency backup unit. The plant's location in Caraguatatuba, a coastal city, places it in a region with tourism and urban development. Its operational status indicates it contributes to local grid stability, though diesel generation typically has higher CO2 and pollutant emissions per MWh compared to natural gas or renewables. The plant's role is likely supplementary to the main grid, providing power during peak demand or outages.

The plant's diesel fuel type results in higher CO2, SOx, and NOx emissions per MWh compared to natural gas or renewable sources. Its location in a coastal urban area may raise concerns about local air quality impacts. The small capacity (2.72 MW) limits its overall environmental footprint, but diesel plants are generally less efficient and more polluting than modern combined-cycle gas turbines.
