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.
The Scornicesti battery will use non-recourse project finance with InvestEU risk support. Its merchant revenue model comes as Romania’s operational storage fleet expands and competition for market revenues grows.
Battery operators across Southeast Europe are increasingly buying solar-heavy midday electricity to sell later, with Bulgaria leading the trend. Serbia has begun recording negative day-ahead prices, creating a potential but variable source of low-cost power for storage.
Romania’s expected offshore gas production growth could leave additional supply discounted domestically unless cross-border capacity can move it to higher-priced markets. Capacity constraints could also increase the value of transmission upgrades and create recurring price spreads with Hungary and Serbia.

Gas is returning to the Southeast European investment agenda, but its role is changing.
The strongest August developments were centred on supply diversification, infrastructure and...
Serbia is expanding gas-supply options with a 1.5 bcm per year interconnector to North Macedonia under construction. The commercial value will depend on delivered costs, route reliability, storage and the expense of new infrastructure.
Romania’s expected offshore gas production growth could leave additional supply discounted domestically unless cross-border capacity can move it to higher-priced markets. Capacity constraints could also increase the value of transmission upgrades and create recurring price spreads with Hungary and Serbia.
Romania’s Neptun Deep development is planned to reach plateau output of about 8 bcm a year, potentially reducing domestic import needs and freeing gas for neighbouring markets. The regional impact will depend on production timing, sales contracts and cross-border capacity.
The Vertical Gas Corridor is approaching a commercial test in 2026/27, with utilisation, northbound flows and cross-border rules set to show whether southern gas can become a regular, cost-effective supply route across Southeast Europe.
Expanding LNG access and pipeline connections are making Southeast European gas prices more responsive to transport costs and supply conditions. This is increasing the importance of spreads against the Dutch TTF benchmark.
