Codelco, the largest copper mining company in the world, canceled it plans to construct Energía Minera, which would have been the largest coal-fired plant in Chile with a capacity of 1,050 megawatts and worth $1.7 billion USD. The company canceled construction in order to avoid conflicts with local communities in the Ventanas area, which is already heavily polluted by three other thermoelectric plants and a copper refinery. Oceana has campaigned against this plant for five years together with allies. With this move, Oceana in Chile achieved its campaign goal of stopping the construction of two coal-fired plants. The other, Punta Alcalde, was cancelled earlier in 2015.
