Power utility PPC will take ongoing global technological developments and their comparative costs into account to decide, in approximately a year’s time, on the fuel to be used at its prospective Ptolemaida V power station in northern Greece from 2028 onwards, when a switch from lignite has been scheduled.
The facility, expected to be completed in 2022, is initially planned to operate as a lignite-fired power station for a six-year period before switching to another fuel or fuels.
All options are being left open, meaning that, beyond 2028, Ptolemaida V could run on natural gas, biomass, waste-to-energy or a combination of these energy sources.
Biomass represents an advantageous option as it can be produced at the utility’s older lignite-fired units in the area, PPC’s chief executive Giorgos Stassis has pointed out.
If a biomass option is chosen, PPC intends to provide land for farmers and cooperatives to cultivate plants for energy production. Yield potential and the local climate promise to be the two main factors behind PPC’s selection of plant species to be cultivated for biomass purposes.
Japan’s Mitsubishi, providing the new facility’s electromechanical equipment, was commissioned, some time ago, to conduct a study determining the optimal choice of fuel for Ptolemaida V beyond 2028.
Continued use of lignite, after 2028, at Ptolemaida V has also been tabled as a possibility if carbon-capture utilization and storage (CCUS) technology is applied for a zero net carbon footprint.
In such a case, the CCUS technology could be applied on a wider scale to lure industrial units to the region for the establishment of a new industrial zone.
