Araucária Gas Power Plant: 484 MW Facility in Brazil

Araucária is a gas-fired power plant located in Brazil, with a capacity of 484.15 MW. The facility is operational and contributes to the country's thermal power generation mix. Brazil's power sector relies heavily on hydroelectricity, but gas plants like Araucária provide essential grid stability and backup during dry periods. The plant operates under Brazil's national environmental and energy regulations, including CONAMA resolutions for air emissions and ANEEL's grid connection standards. Gas power plants in Brazil typically use combined cycle technology for efficiency, though specific technology details for Araucária are not confirmed. The 484 MW capacity places it in the medium-to-large scale for gas plants in the country. Araucária plays a role in supporting Brazil's energy security, particularly in the southern region. Its gas-fired generation helps balance intermittent renewable sources and meets peak demand. The facility's location near urban areas underscores the importance of emission controls to minimize local air quality impacts.

Gas power plants like Araucária have lower CO2 emissions per MWh compared to coal or oil, but still contribute to greenhouse gas emissions. The plant's proximity to populated areas requires adherence to air quality standards for NOx and SOx. Brazil's regulatory framework, including CONAMA Resolution 382/2006, sets emission limits for thermal power plants. The facility's age and technology (subcritical vs.
