Geramar I (Antiga Tocantinópolis) - Diesel Power Plant in Brazil

Geramar I (Antiga Tocantinópolis) is a diesel power plant located in Brazil with a capacity of 165.87 MW. The plant is operational and uses oil as its primary fuel, contributing to the country's power generation mix. Brazil's power generation sector is regulated by national standards, including emission limits for SOx, NOx, and particulate matter. Diesel plants like Geramar I typically operate as peaking or backup units, supporting grid stability during high demand periods. The plant's capacity places it in the medium-scale range for diesel power generation. As a diesel-fired facility, Geramar I has a higher carbon footprint compared to natural gas or renewable sources. Its operational role in the local grid is significant for meeting peak demand, though it may face regulatory scrutiny under Brazil's environmental policies. The plant's location in the state of Maranhão serves the regional energy needs.

The plant's diesel fuel type results in higher CO2, SOx, and NOx emissions per MWh compared to natural gas or renewables. Its capacity of 165.87 MW places it in a medium-scale category, with potential local air quality impacts. Proximity to populated areas could increase exposure to emissions, though specific distances are not detailed. Brazil's environmental regulations, including CONAMA resolutions, set emission standards for such facilities.
