Serbia reported around 2 GW of battery energy storage system connection agreements in 2026, but its first standalone projects still need to establish a local financing template. The terms they set are expected to shape leverage, security, revenue haircuts and sponsor support in a sector without a widely replicated domestic model.
Under procedures set by EMS, Serbia’s transmission system operator, sponsors of transmission-connected projects must provide a construction bank guarantee within 60 days of receiving a connection study. The guarantee must be in place before the connection-contract process can advance. This requires sponsors to have balance-sheet capacity before projects generate operating revenue, creating an early financing filter.
Domestic commercial banks may finance construction if they are comfortable with exposure to merchant-market risk. A contracted industrial offtaker, an optimizer floor or a balancing-services agreement could materially increase bank leverage compared with a project relying purely on arbitrage. Such revenue arrangements could therefore influence financing terms for Serbia’s first standalone batteries.
Financing options and regional precedent
Participation by international financial institutions, risk guarantees or blended financing structures could allow local banks to take part with less exposure to early-market uncertainty. Equipment-vendor finance and sponsor equity could also help bridge the first projects, particularly where batteries are co-located with solar or wind generation.
Romania offers a regional non-recourse financing precedent with the 127 MW / 254 MWh Scornicesti project. The European Bank for Reconstruction and Development (EBRD) provided non-recourse project financing.
The first Serbian financing for a standalone battery is expected to establish the assumptions banks use for spread compression, degradation, reserve accounts and terminal value. Once a financing structure has closed and performed, the cost of capital for the next wave of standalone projects in Serbia should become easier to price. Domestic banks’ willingness to finance construction will depend on their comfort with merchant risk.
