Aeroporto Internacional Salgado Filho Diesel Power Plant, Porto Alegre, Brazil

Aeroporto Internacional Salgado Filho is a diesel power plant located at Salgado Filho International Airport in Porto Alegre, Brazil. With a capacity of 2.704 MW, it is a small-scale facility designed to provide emergency or backup power to the airport. The plant uses oil as its primary fuel, typical for diesel generators in standby applications. The plant operates under Brazil's national environmental regulations, which include emission standards for stationary engines. Diesel generators are subject to limits on particulate matter, nitrogen oxides, and sulfur oxides, enforced by state environmental agencies. The facility's small capacity and backup role mean it runs intermittently, reducing its overall environmental impact compared to baseload plants. As a critical infrastructure component, the plant ensures uninterrupted power for airport operations, including lighting, baggage handling, and air traffic control. Its location at an international airport underscores its importance for transportation and economic activity in the Porto Alegre region. The plant's operational status is active, supporting grid resilience during outages.

The plant's use of oil as fuel results in emissions of CO2, SOx, and NOx, though its small capacity and intermittent operation limit overall impact. Located in an urban area near Porto Alegre, the plant's emissions may affect local air quality during operation. Brazil's regulatory framework, including CONAMA resolutions, sets emission limits for stationary sources, and the plant likely complies with applicable standards. Its backup role means it operates only during grid failures, reducing cumulative environmental footprint.
