RJO-AM Diesel Power Plant, Rio de Janeiro, Brazil

RJO-AM is a diesel power plant located in Rio de Janeiro, Brazil, with a capacity of 4.8 MW. It is operational and uses oil as its primary fuel. The plant contributes to the local energy supply in the Rio de Janeiro region. As a small-scale diesel facility, RJO-AM operates under Brazil's national environmental regulations, including CONAMA resolutions for air emissions. Diesel plants typically have higher CO2 and particulate emissions compared to natural gas, but their small capacity limits overall impact. The plant's technology is likely based on reciprocating engines, common for this scale. The plant's location near Rio de Janeiro, a densely populated urban area, means its emissions are subject to local air quality standards. Its role is likely to provide peaking power or backup generation, supporting grid stability during high demand periods. Typical diesel plants of this size may have basic pollution control equipment.

The plant's use of oil fuel results in higher CO2, SOx, and NOx emissions per MWh compared to natural gas or renewables. Its location near Rio de Janeiro, a major urban center, means emissions can affect local air quality. The small capacity (4.8 MW) limits overall environmental footprint, but diesel plants are generally less efficient than combined cycle gas turbines. Regulatory compliance with Brazilian emission standards is expected.
