Around 2 GW of battery energy storage system connection agreements were reported in Serbia in 2026, but the first standalone projects must establish a local financing template. Their terms are expected to set precedents for leverage, security, revenue haircuts and sponsor support in a market without a widely replicated domestic model.
EMS procedures for transmission-connected projects require sponsors to provide a bank guarantee for construction within 60 days after delivery of a connection study. The guarantee is required before the connection-contract process advances, putting an early financing test in front of sponsors that have yet to generate operating revenue.
Domestic commercial banks can finance construction if they are comfortable with merchant risk. A contracted industrial offtaker, an optimiser floor or a balancing-services agreement could materially increase bank leverage compared with a project relying on pure arbitrage.
International financial institution participation, risk guarantees or blended financing structures could enable Serbian banks to participate with lower exposure to early-market uncertainty. Equipment-vendor finance and sponsor equity could also help bridge the first projects, particularly when batteries are co-located with solar or wind generation.
Romania offers a regional non-recourse financing precedent through Scornicesti, a 127 MW / 254 MWh battery project financed on a non-recourse basis by the European Bank for Reconstruction and Development (EBRD).
The financing structure of Serbia’s first standalone battery projects is expected to establish the assumptions banks use for spread compression, degradation, reserve accounts and terminal value. Those factors will inform the cost of capital for future projects. Once a financing structure closes and performs, the cost of capital for Serbia’s next wave of standalone battery projects should become easier to price.
