Power utility PPC will wait for the European Commission’s finalized decisions on a strategic plan intended to end the EU’s reliance on Russian fossil fuels before it decides on the operating and conversion details of its prospective Ptolemaida V power station in northern Greece, to be launched as a lignite-fired facility before being converted to natural gas.

The PPC board is now expected to decide on Ptolemaida V’s conversion date towards the end of this year, according to sources.

Ptolemaida V, expected to undergo a trial run in the second half of the year before being launched late in the year or early in 2023, will be introduced as Greece’s last lignite-fired power station.

Early in April, prime minister Kyriakos Mitsotakis announced extensions to withdrawal dates for older lignite-fired power stations that were originally headed for closure prior to 2025. At the time, the prime minister also informed that Ptolemaida V could now operate as a lignite-fired unit until 2028.

Revisions to the country’s decarbonization plan have been prompted by energy security concerns following Russia’s invasion of Ukraine and the exacerbation of the preceding energy crisis as a result of this war.

The Greek government has decided to increase lignite mining output as a safety measure should Russia interrupt its natural gas supply.

A year ago, PPC had announced it intended to convert Ptolemaida V into a natural gas-fired facility as of 2025, but the latest energy security concerns froze this plan.
