The closure of its two coalfired power plants, Sines and Pego, is critical to decarbonizing Portugal's economy as they accounted for 20% of the nation's greenhouse gas emissions . The Pego Power Plant underwent a retrofitting process in 2009 to reduce emissions and was overseen by a holding group consisting of three companies .

CoalFired Power Plant: Coalbased power plants are a type of power plant that uses coal combustion to generate electricity. Countries like South Africa use coal for 94% of their electricity, and China and India use 7075% of coal for their electricity needs; however, the amount of coal in China dwarfs that in other countries.

An integrated gasification combined cycle (IGCC) is a technology using a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ().It can then remove impurities from the syngas prior to the electricity generation cycle. Some of these pollutants, such as sulfur, can be turned into reusable byproducts through the Claus process.
