Latasa Santa Cruz Diesel Power Plant in Rio de Janeiro, Brazil

Latasa Santa Cruz is a diesel power plant situated in Rio de Janeiro, Brazil, with an installed capacity of 4.48 MW. The facility is operational and contributes to the region's power generation mix, primarily utilizing oil as its fuel source. As a small-scale plant, it plays a role in meeting local electricity demand, particularly in areas where grid connectivity may be limited. The plant operates under Brazil's national environmental and energy regulations, which include emission standards for stationary sources and licensing requirements from agencies such as IBAMA and state-level environmental bodies. Diesel power plants in Brazil are subject to limits on sulfur oxides (SOx), nitrogen oxides (NOx), and particulate matter, aligning with the country's commitments to air quality management. The technology employed is typical for small-scale diesel generation, offering flexibility and rapid start-up capabilities. Environmentally, the plant's oil-based fuel results in higher CO2 emissions per MWh compared to natural gas or renewable sources. Its location in an urbanized area of Rio de Janeiro necessitates careful emission control to minimize local air quality impacts. Despite its modest capacity, Latasa Santa Cruz contributes to grid stability and provides backup power, supporting the region's energy security.

The plant's use of oil as fuel results in significant CO2, SOx, and NOx emissions relative to its capacity. Located in the densely populated Rio de Janeiro metropolitan area, the facility must comply with stringent air quality standards to mitigate health and environmental impacts. The small scale limits its overall footprint, but local emissions can affect nearby communities.
