In Serbia, battery project values increasingly depend on securing viable grid access without costly reinforcement obligations. EMS updated its connection-request lists on 4 November 2026; the transmission system operator maintains the lists and records requests for connection-study agreements, providing a view of the country’s active project pipeline.
As of 2 February 2026, EMS had recorded 30 requests for connection-study agreements for non-RES objects under the current process. Standalone storage has separate data requirements for connection studies and a distinct application route for connection approval under Serbia’s current framework.
Grid connection requirements
Existing active customers with controllable load or storage on internal installations below 10 MW, and without export capability, can use a simplified technical-study process. The stated fee for the study is EUR 15,000 plus VAT. Larger merchant-scale battery projects face full network analysis and may need to build missing infrastructure or accept operational limits.
These requirements increase the importance of a project’s grid position. Battery hardware is becoming cheaper and more standardised, but grid access is not; a credible transmission or customer-side connection position may therefore be more valuable than equipment chosen for delivery several years later. Potential infrastructure works and operating restrictions also create scarcity value around viable grid nodes.
Financing and project due diligence
Land and low-cost battery equipment procurement may not be enough to make a project financeable without a realistic connection. A mature connection path, clearly defined reinforcement scope and manageable bank-guarantee requirements can help attract capital before the final original equipment manufacturer is selected.
Investors acquiring Serbian BESS development platforms should begin due diligence with the grid file. Checks include study status, the connection agreement, guarantee obligations, land rights for the connection route, curtailment or other operating limits, and responsibility for reinforcement costs. Connection quality and reinforcement obligations are becoming core valuation inputs for Serbian storage development.
