Overview
Termoelectrica Tocopilla (U12) is a 1001.7 MW coal power plant in Tocopilla, Chile, operated by E-CL. It is a key asset in the country's northern grid, supporting mining and industrial demand.
Termoelectrica Tocopilla (U12) is a coal-fired power plant located in Tocopilla, Chile, with a capacity of 1001.7 MW. Owned and operated by E-CL, it is one of the larger coal units in the region, contributing significantly to the local power supply. The plant is situated in the Antofagasta Region, an area with high energy demand from mining operations. 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. Chile's energy mix includes coal, natural gas, hydro, and renewables, with coal accounting for a substantial share of baseload generation. Environmentally, the plant's coal combustion results in CO2, SOx, and NOx emissions, with potential impacts on local air quality. Its coastal location may influence dispersion patterns. The facility plays a critical role in grid stability for the northern interconnected system (SING), serving mining and industrial customers. E-CL has been exploring repowering or retirement options as Chile transitions toward cleaner energy sources.
Environmental context
The Tocopilla area has a desert coastal climate with limited rainfall, which can affect pollutant dispersion. The plant's coal combustion emits CO2, SOx, NOx, and particulate matter, contributing to local and regional air quality concerns. Proximity to the Pacific Ocean may lead to marine impacts from cooling water discharge. Chile's environmental framework includes emission limits for thermal power plants, and the facility is subject to monitoring and reporting requirements under the country's environmental law.
