Five plants at the heart of the Western Macedonia cluster
The cluster includes several identified installations. The “Phoebe” plant (550 MW), located near Pontokomi, would produce an estimated 880 GWh annually, representing 1.8% of Greek interconnected system output, covering approximately 196,000 households and preventing nearly 440 kt (kilotonnes) of CO2 per year. The Amyntaio complex (940 MW), developed in partnership with RWE across the Rodonas, Filotas, Lakkia, and Perdikkas sites, would reach 1,500 GWh per year for approximately 298,000 households, preventing more than 750 kt of CO2. The “Helios Velos 1” plant (200 MW), near Ptolemaida, would produce 320 GWh annually for approximately 71,000 households, preventing nearly 160 kt of CO2. Two 80 MW installations — “Exochi 7” and “Akrini” — each generate approximately 122 GWh per year, covering around 27,000 households each and preventing nearly 61 kt of CO2 annually. Ten smaller photovoltaic stations on other former mining sites in the region complete the ensemble.
Konstantinos Mavros, Deputy CEO for Renewable Energy Sources (RES) at PPC Group, notes that the share of thermal generation in the Greek electricity mix fell from 67% to 50% between 2019 and today, in less than seven years. He describes Western Macedonia as the country’s “new green energy hub,” hosting what he calls Europe’s largest photovoltaic cluster on former lignite mining sites, alongside storage units contributing to grid stability.
Energy storage: two BESS stations completed, pumped storage units authorized
PPC Renewables, a wholly owned subsidiary of PPC Group, has completed the construction of two battery energy storage system (BESS) stations in Ptolemaida and Meliti. Construction of a third BESS station in Amyntaio is progressing rapidly. PPC also indicates that it has secured the necessary regulatory approvals for two pumped storage units in Kardia and South Field. These storage deployments aim to optimize the use of generated solar energy and contribute to grid stability.
On March 13, 2026, PPC Group launched a bond issue amounting to €5 million, reserved exclusively for residents of the Kozani and Florina regions. The subscription period runs until April 17, 2026. The nominal value of each bond is set at €100, with a minimum subscription of five bonds and a maximum of 250 bonds per investor. The guaranteed annual return is 8%, with PPC indicating that investors’ initial capital would increase by 40% before taxes over five years.
