PPC starts building two battery storage systems in northern Greece

Public Power Corp. (PPC Group) is launching construction on two battery energy storage systems (BESS) in northern Greece, of 48 MW / 96 MWh and 50 MW / 100 MWh. There is currently no larger BESS in Southeastern Europe, but the Oslomej solar park in North Macedonia is expected to get a battery system of 62 MW in operating power by the end of the year.

PPC’s Melitis 1 battery system will be located in the vicinity of its future photovoltaic plants in the Western Macedonia region, and Ptolemaida 4 will be built in the area of the former Ptolemaida coal mines. The energy storage units are intended to support the operation of adjacent photovoltaic plants.

The battery systems are targeted for completion within the year

The systems will use liquid-cooled batteries with the lithium iron phosphate (LFP) technology, maximizing both energy utilization and safety during operation, according to a statement from the Greek company, controlled by the government through a minority stake. It expects to complete the construction within the year.

PPC Group’s investment plan for the 2025-2027 period envisages BESS projects totaling 600 MW, which are currently at various stages of implementation in Greece and elsewhere in Southeastern Europe.

Konstantinos Mavros, the group’s deputy CEO responsible for renewable energy sources, said PPC is a leader in investing in energy storage systems. “In the coming years it will significantly increase investments in all flexible generation systems through energy storage,” he stated.

PPC plans 600 MW of battery projects in Southeastern Europe

PPC Group recently started building a battery system in neighboring Bulgaria with 25 MW in operating power and a capacity of 55 MWh. The facility would support the operation of a new solar power plant with a total capacity of 165 MW.

The company runs renewable energy systems with a total capacity of 6.2 GW in Greece, Romania, Italy, and Bulgaria. Its investment plan envisages increasing the capacity from renewables to 11.8 GW by 2027. PPC’s strategic goal is to expand into new renewable energy technologies, such as offshore wind farms and floating solar parks.
