Maracanaú I Diesel Power Plant, Brazil - 168 MW Oil-Fired Facility

Maracanaú I is a diesel power plant located in Brazil, with a capacity of 168 MW. The plant operates on oil as its primary fuel, placing it within the medium-scale range for power generation facilities in the country. Its operational status is active, supporting regional electricity supply. The plant's technology is typical for diesel-fired generation, which offers flexibility and rapid start-up capabilities. In Brazil, power generation is regulated by national standards, including environmental licensing requirements from IBAMA and state agencies. Diesel plants like Maracanaú I are subject to emission controls for SOx, NOx, and particulate matter, aligning with the country's environmental policies. Maracanaú I plays a role in Brazil's energy mix, providing dispatchable power that can complement renewable sources. Its location near populated areas may influence local air quality considerations. The plant's operation contributes to grid stability and meets demand during peak periods or when hydroelectric generation is low.

The plant's use of oil as fuel results in CO2 emissions and other pollutants such as SOx and NOx, which can impact local air quality. Proximity to urban areas may increase exposure to these emissions. The facility's age and technology level (diesel) typically have lower efficiency compared to combined cycle gas turbines, leading to a higher carbon footprint per MWh. Regulatory oversight under Brazilian environmental law aims to mitigate these impacts through emission limits and monitoring.
