ANTILHUE Diesel Power Plant, Chile | 101.3 MW Oil-Fired Facility

ANTILHUE is a diesel power plant located in Chile, owned and operated by COLBUN S.A. With a capacity of 101.3 MW, it falls within the medium-scale range for power generation facilities in the country. The plant is operational and contributes to Chile's energy mix, which includes a growing share of renewables alongside conventional thermal generation. The plant uses oil as its primary fuel, a common choice for diesel power plants. In Chile, such facilities are subject to national emission standards and environmental regulations, including those set by the Ministry of Environment. The plant's technology is typical for diesel engines, which offer flexibility and quick start-up capabilities, making them suitable for peaking power or backup generation. ANTILHUE plays a role in supporting grid stability in the Los Ríos region. Its location near the city of Valdivia places it within a region with significant industrial and residential electricity demand. The plant's operation is integrated into Chile's Central Interconnected System (SIC), which serves the majority of the country's population.

The plant's use of oil fuel results in CO2, SOx, and NOx emissions, which are regulated under Chile's environmental laws. Its proximity to populated areas and the Valdivia River basin may require adherence to local air quality standards. The facility's age and technology level influence its emission profile, with older diesel plants typically having higher emission intensities compared to modern combined-cycle gas turbines.
