MENA BARRETO - 1 Diesel Power Plant, Brazil | Small-Scale Power Generation

MENA BARRETO - 1 is a diesel power plant located in Brazil, with coordinates near Rio de Janeiro. The facility has a capacity of 2.1 MW, placing it in the small-scale category for power generation. It is currently operational and uses oil as its primary fuel. The plant operates under Brazil's national environmental regulations, which include emission standards for air pollutants such as SOx, NOx, and particulate matter. Diesel power plants of this size typically use reciprocating engines, which are common for backup or peaking power in regions with grid constraints. Brazil's energy mix is dominated by hydroelectricity, but diesel plants like this one provide essential reliability during dry periods or peak demand. As a small-scale diesel facility, MENA BARRETO - 1 contributes to local grid stability and energy security. Its location near a populated area underscores the importance of managing emissions to minimize environmental impact. The plant's role in the local energy system is significant for ensuring continuous power supply, especially in areas where renewable sources may be intermittent.

The plant's use of oil as fuel results in CO2, SOx, and NOx emissions, which are regulated under Brazilian environmental law. Its proximity to the Rio de Janeiro metropolitan area means that air quality impacts are a key consideration. Small diesel plants like this one are often used for peaking power, which can lead to higher emission intensity per MWh compared to baseload plants. Compliance with national emission standards is essential to mitigate local environmental effects.
