Turkish company Fortis Energy has announced plans to integrate battery storage capacity at the Oslomej solar power plant, making it the second-largest hybrid power facility in the Western Balkans.
Fortis Energy developed North Macedonia’s largest solar power plant in 2023, with electricity production beginning in 2024. The state-owned power utility ESM selected the company in 2021 for a public-private partnership to build a 50 MW solar facility, which was later expanded to 79.9 MW. The addition of battery storage will now transition the plant into a hybrid system.
The Oslomej solar power plant is located at TPP Oslomej, one of North Macedonia’s two coal mining and power plant complexes. Built on a depleted open-pit mine, the facility generates approximately 120 GWh of electricity annually and consists of nearly 124,000 photovoltaic panels.
The planned lithium-ion battery energy storage system (BESS) will have a total capacity of 104 MWh, with an operational capacity of 62 MW. Pomega Energy Storage Technologies, a subsidiary of Turkish company Kontrolmatik Technologies, will install the system under a $19.65 million agreement. The system will allow the facility to supply electricity for up to two hours at full capacity.
Fortis Energy expects the battery integration to be completed, and the hybrid facility to become operational, in the second half of 2025.
