The TPP ecological refurbishment includes the construction of de-sulphurization (FGD) and de-nitrification (SCR) installations, upgrading the electro-filtering plant, construction of a wastewater treatment facility, and reconstruction of the internal system for transporting by-products, as well as building a heating station, as a part of the district heating system. The emission reductions anticipated by 2030 are mainly due to the temporary closure of the plant in 2021 and 2022 due to refurbishment.
