Greece’s biggest power utility Public Power Corp. said on Tuesday that a new coal-fired plant under construction will be switched on by March 2023. PPC, which is 34% owned by the state, had started building a new unit in the northern Greek region of Ptolemaida before the energy crisis took hold. The 660-megawatt plant will start trial operation in the second half of the year before it reaches commercial operation beginning in the first quarter of 2023. The utility said it will gradually ramp up coal-fired generation in the coming 12 months, adding that phasing out lignite was still “a strategic decision” for the group.
