Background

The Sulcis power plant originally began operating in 1965 with two 240 MW units. Another 240 MW unit was added in 1986, while the first two were converted/replaced by a 350 MW circulating fluidized bed boiler unit in 2005. The power plant is operated by Enel, Italy's largest power generator, and supplies power to an adjacent Alcoa plant.[1]

The plant is equipped with both desulfurization and denitrification units. The South African coal that the plant uses contains 6-8% sulfur content, which produces higher amounts of fly ash and wastewater.[1] Since Italian and EU environmental regulations were strengthened, wastewater from the plant's desulfurization unit cannot be discharged into the sea. To resolve this, ENEL has decided to install a Zero Liquid Discharge (ZLD) unit, which eliminates wastewater discharge.[2]

World Coal reported that the plant had exceeded both the revised regional nitrous oxide (by 68%) and sulfur oxide (by 83%) limits in 2014.[3] According to Beyond Coal, the Sulcis power plant produced an estimated 1.1 million tonnes of CO2 in 2017.[4]

No Closure Yet

In late 2020, Enel announced it would be shutting down three of its coal plants in an effort to meet the country's energy transition. However, the Sulcis plant was not included because it had previously been deemed as 'essential' for grid security by Italian power grid operator Terna.[5]
