Geramar II (Antiga Nova Olinda) - Diesel Power Plant in Brazil

Geramar II (Antiga Nova Olinda) is a diesel power plant located in Brazil, with a capacity of 165.87 MW. The plant uses oil as its primary fuel and is currently operational. It contributes to the country's power generation mix, particularly in regions where diesel plants provide flexibility and peaking capacity. The plant operates under Brazil's national environmental and energy regulations, which include emission standards for SOx, NOx, and particulate matter. Diesel plants in Brazil are subject to licensing by environmental agencies and must comply with air quality standards. The technology typically involves internal combustion engines, which are efficient for mid-scale generation but have higher CO2 emissions per MWh compared to natural gas or renewables. As a mid-sized diesel facility, Geramar II plays a role in grid stability and meeting peak demand. Its location in Brazil's northeast region, near the city of São Luís, positions it to support local industrial and residential electricity needs. The plant's operational status ensures continued contribution to the regional power supply.

The plant's use of oil as fuel results in significant CO2, SOx, and NOx emissions per MWh, contributing to local air quality concerns. Its proximity to populated areas may increase exposure to pollutants. The facility's age and technology (likely internal combustion engines) influence its environmental footprint. Brazil's regulatory framework, including CONAMA resolutions, sets emission limits for such plants.
