A development decision on power utility PPC’s planned lignite-fired Ptolemaida V power station is now officially preoccupying authorities, examining various options, including a fuel switch to natural gas.

All appears possible at this stage. Besides an in-progress report from the McKinsey consulting firm, examining all possible scenarios for the unit along with PPC, Prime Minister Kyriakos Mitsotakis made reference to the matter for the first time yesterday while speaking at the UN Climate Change Summit. He spoke of total decarbonization in Greece by 2028.

Echoing this remark, energy minister Costis Hatzidakis left open the possibility of a zero-lignite energy mix by 2030 when asked if Greece’s new National Energy and Climate Plan, to soon be submitted to Brussels, would include such a target.

Hatzidakis hinted that such a prospect is possible. However, he did not commit on how the government would choose to handle Ptolemaida V.

“If you were to ask me about the existing lignite-fired power stations, I would have answered that we will have a clear picture on how many of these units are sustainable in three to four weeks,” Hatzidakis noted. “But this is not so for Ptolemaida V, where the matter is very complicated. At this stage, nobody can talk of an optimal solution.”

Contrary to the previous PPC administration, the power utility’s new leadership, headed by Giorgos Stassis, does not consider the Ptolemaida V investment a certainty. However, Stassis and his associates are also aware of how complex the matter is, making abandonment difficult.

For example, abandoning the Ptolemaida V project would severely impact the northern region’s local economy, dependent on lignite activity. Also, PPC has already spent close to 950 million euros. Turbine and generator orders have arrived, while agreements, including EPC contracts, have been signed.

As for the thoughts of a fuel switch, from lignite to natural gas, PPC would be better off building a new gas-fired power station in Lavrio, southeast of Athens, close to gas sources and urban centers consuming considerable electricity amounts.
