Overview
Guacolda is a 760 MW coal-fired power plant in Chile, operated by AES Gener S.A. It is a significant thermal generation asset in the country's energy mix.
Guacolda is a coal-fired power plant located in the Huasco province of Chile, near the coast. With a capacity of 760 MW, it is one of the larger coal plants in the country, contributing to Chile's baseload power generation. The plant is owned and operated by AES Gener S.A., a major energy company in Latin America. The plant operates under Chile's environmental regulations, which include emission standards for SOx, NOx, and particulate matter. Chile's energy sector has been diversifying into renewables, but coal remains a key component of the grid. Guacolda's coastal location provides access to cooling water and fuel imports. The plant's emissions contribute to local air quality concerns, particularly in the Huasco Valley. Its role in the grid is significant, providing stable power to the central interconnected system (SIC). The facility's age and technology type are factors in its environmental footprint.
Environmental context
The plant's coal combustion produces CO2, SOx, NOx, and particulate matter, impacting local air quality. Its coastal location near populated areas raises concerns about health effects. The facility's age and subcritical technology result in lower efficiency and higher emissions per MWh compared to modern supercritical or CCGT plants. Chile's regulatory framework includes emission limits, but coal plants remain a significant source of greenhouse gases.
Frequently asked questions
Guacolda is located in the Huasco province of Chile, near the coast on the Atacama Desert coast.
The Guacolda power plant has a capacity of 760 megawatts (MW), making it one of the larger coal-fired plants in Chile.
The Guacolda power plant is owned and operated by AES Gener S.A., a leading energy company in Latin America.
Coal power plants in Chile must comply with national emission standards for SOx, NOx, and particulate matter, as well as greenhouse gas reporting requirements. The country is also part of international climate agreements.
Guacolda uses subcritical coal technology, which is less efficient and produces higher emissions per MWh compared to supercritical or combined cycle gas turbine (CCGT) plants. This results in a larger carbon footprint and greater local air pollution.
