Background on Plant

Megalopoli power station was a four-unit coal-fired power plant with a total capacity of 850 MW. The first two units of 125 MW each were completed in 1970 and retired in 2011. Units 3-4 of 300 MW each are still operating. The plant is owned by Public Power Corporation. Megalopoli was extended with two 400-MW CCGT blocks in 2012.[1]

On September 1, 2019, PPC said it would begin to close the Megalopoli and Amyntaio power station in consultation with local communities, with consultations to begin in 2020.[2]

On September 13, 2019, the Greek Supreme Court declined to renew the environmental permits of the Megalopoli A & B lignite power plants. Both lignite stations emit higher levels of sulfur dioxide and nitrogen oxides than allowed by EU standards.[3]

In September 2019 the Greek Prime Minister announced the country will phase out all coal-powered electricity production by 2028. Megalopoli power station is planned for retirement in 2022-2023.[4]

In December 2021, PPC stated that the operating life of the remaining coal-fired capacity at the Megalopoli power station would be extended until 2025.[5]

In 2022, Unit 3 was retired.[6]
