Refineries in Croatia, Romania, Bulgaria and Serbia are gaining strategic importance as diesel supplies tighten and long-distance imports become scarce, costly or unreliable. Local production can shorten supply chains and reduce exposure to disrupted seaborne trade, while refinery operations and crude deliveries remain key to availability.
Credible grid access and manageable reinforcement obligations are becoming central to the value and financeability of battery storage projects in Serbia. EMS updated its connection-request lists on 4 November 2026, reflecting an increasingly active project pipeline.
Drought is reducing hydroelectric output and constraining nuclear generation across the Balkans, increasing exposure to electricity imports. The pressure highlights the role of diversified generation, storage and interconnection.
Bulgaria’s operating battery fleet was reported at 6.23 GW by late October, while EBRD and Raiffeisen are financing a new 246 MW battery at Tenevo. The reported fleet and energy-flow figures require verification against underlying data.

Around 2 GW of battery storage connection agreements were reported in Serbia in 2026, but the first standalone projects still need to establish a local financing template. EMS requires a construction bank guarantee before transmission-connected projects can advance to connection contracts.
Montenegro is moving toward a strategic-partner model for a 60 MW / 240 MWh battery project after the government did not approve borrowing for EPCG’s planned procurement. A government working group is now tasked with the strategic project.
Continuous, reliability-sensitive demand could help data centres link renewable power with contracted battery storage. October price spikes in Hungary and Serbia underline the potential value of storage beyond backup.
Around 2 GW of battery storage connection agreements were reported in Serbia in 2026, but the first standalone projects still need to establish a local financing template. EMS requires construction guarantees before transmission-connected projects can advance to connection contracts.
EPCG’s memorandum with Japan’s PowerX sets an indicative target of about 500 MWh of battery storage over an initial three-year period. The commercial opportunity is to coordinate batteries with hydro, rising solar output and cross-border trading, rather than rely on standalone arbitrage.
Montenegro is moving to a strategic-partner model for a 60 MW / 240 MWh battery project after EPCG’s borrowing-funded procurement was cancelled and a pilot tender drew no bids. The project is envisioned as the first phase of a broader partnership.
Southeast Europe faces a growing power-system flexibility shortage as grids, storage and dispatchable capacity lag behind project growth and rising volatility. Country-level pressures range from heavy imports in Serbia to negative prices in Croatia and faster battery deployment in Bulgaria.
Kosovo enters its highest-demand months with the 260 MW B1 unit still unavailable, increasing reliance on electricity imports. The operator has not set a return date as regional prices and interconnector availability remain key variables.
Austria's Verbund has signed a power-purchase agreement for the first project selected in Albania's first wind auction to reach construction readiness. Commercial operation is targeted for the first quarter of 2028.
Bulgaria’s operating battery fleet was reported at 6.23 GW by late October, while EBRD and Raiffeisen are financing a new 246 MW battery at Tenevo. The reported fleet and energy-flow figures require verification against underlying data.
Buyers took 34,000 of 35,000 wind guarantees of origin offered in North Macedonia’s first auction. The sale adds a price-discovery mechanism to the country’s existing administrative framework.
