Power utility PPC plans to prematurely withdraw its Megalopoli III lignite-fired power station in mid-2021, six months earlier than planned, energy minister Costis Hatzidakis announced yesterday while presenting the government’s decarbonization plan.
A decision was taken to shut down Megalopoli III, in the Peloponnese, ahead of schedule as this facility has operated for a total of just one week since spring, indicating its output is no longer required to secure grid sufficiency.
In his comments to media yesterday, Hatzidakis, the energy minister, highlighted the high cost entailed in operating lignite-fired power stations.
The averages variable cost of lignite-based energy is €0.80 per MWh, well over the System Marginal Price of €0.45 per MWh, according to data presented by the minister.
A 550-MW PPC lignite-fired power station at Amynteo, northern Greece, has already been shut down.
For the time being, no other PPC lignite unit withdrawal plan revisions were reported at yesterday’s news conference.
Kardia III and IV are still planned to be withdrawn in 2021. These will be followed by Agios Dimitrios I, II, III and IV, representing a total capacity of 1,100 MW, in 2022. Their withdrawal will coincide with the entry of a new unit, Ptolemaida V, to offer a 610-MW capacity. It will be launched as a lignite-fired unit before continuing to generate on cleaner fuel as of 2028.
PPC is also scheduled to withdraw 260-MW Megalopoli IV, 290-MW Meliti I and 340-MW Agios Dimitrios V in 2023.
