Battery storage projects in Romania and Bulgaria are drawing EBRD-backed financing, while a project in North Macedonia has sovereign and concessional support. Lenders need to test technical performance, grid access, market revenues and debt-service coverage under realistic downside scenarios.
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.
CBAM requirements could affect the revenue and financing of renewable projects in Serbia, Montenegro and the wider Western Balkans. The Energy Community Secretariat’s Q2 2026 assessment highlights verification, power purchase agreement eligibility and access to EU market prices as challenges.
Battery storage can make renewable electricity more predictable for Serbian exporters and improve the commercial case for renewable projects. It does not reduce embedded emissions by itself or replace CBAM evidence requirements.
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.
Battery operators across Southeast Europe are increasingly buying solar-heavy midday electricity and shifting it for sale in later hours, with Bulgaria leading the trend. Serbia has begun recording negative day-ahead prices, which can provide a variable source of low-cost electricity for storage.
North Macedonia is structuring its planned 100 MW / 400 MWh Bitola battery as strategic grid infrastructure, with an estimated cost of EUR 98 million. The EBRD is considering a sovereign-guaranteed loan of up to EUR 33.1 million, alongside other expected financing.
Serbian industrial companies must weigh owning batteries against buying flexibility as a service. The choice depends on whether factory-specific savings or market optimisation provides most of the battery’s value.
