HUASCO Diesel Power Plant, Huasco, Chile | 57.7 MW Oil-Fired Facility

HUASCO is a diesel power plant located in Huasco, Chile, with a capacity of 57.7 MW. It is owned and operated by Empresa Nacional de Electricidad S.A. (ENDESA), a major utility in the country. The plant plays a role in supplying electricity to the region, particularly during peak demand or when renewable sources are insufficient. The plant uses oil as its primary fuel, which is typical for diesel power plants in Chile. While diesel plants offer flexibility and quick startup, they have higher emissions per MWh compared to natural gas or renewables. The plant operates under Chile's environmental regulations, which include emission standards for SOx, NOx, and particulate matter, aligned with the country's commitment to the Paris Agreement. Huasco is a coastal city in the Atacama Region, an area with significant mining activity. The plant's location supports local industrial and residential electricity needs. As part of ENDESA's portfolio, HUASCO contributes to grid stability, though its diesel-based generation is being phased out in favor of cleaner sources under Chile's energy transition plan.

The HUASCO diesel power plant uses oil, which results in higher CO2, SOx, and NOx emissions compared to natural gas or renewable sources. Its location near the coastal city of Huasco may affect local air quality, especially given the region's mining and industrial activities. The plant's age and technology (likely subcritical) contribute to its environmental footprint. Chile's regulatory framework, including emission standards and carbon taxes, applies to this facility.
