Tarauacá – CEA Diesel Power Plant in Tarauacá, Brazil

Tarauacá - CEA is a diesel power plant located in Tarauacá, Acre, Brazil. With a capacity of 7.65 MW, it is a small-scale facility within the Brazilian power generation sector, which relies heavily on hydroelectricity but also uses thermal plants in remote areas. The plant operates on oil as its primary fuel, typical for diesel power plants in isolated regions of the Amazon where grid connectivity is limited. Brazil's regulatory framework for thermal power generation includes national emission standards under CONAMA resolutions, which set limits for SOx, NOx, and particulate matter. Diesel plants in this region often use reciprocating engines. Tarauacá - CEA plays a role in providing electricity to the local community in the western Amazon, an area with limited infrastructure. Its operation contributes to energy access in a region where hydroelectric power is not always feasible due to distance and environmental constraints. The plant's environmental impact is tied to its fuel combustion, which produces CO2 and local air pollutants.

The plant is located in the Amazon rainforest region, an ecologically sensitive area with high biodiversity. Its diesel combustion emits CO2, SOx, and NOx, contributing to local air pollution and greenhouse gas emissions. Proximity to populated areas may increase exposure to pollutants. The small capacity limits overall impact, but the use of oil as fuel presents higher emissions per MWh compared to natural gas or renewables.
