Electricity flows, price signals and grid constraints
Serbia is planning nearly 7TWh of electricity imports despite an expected net-export balance. Serbia’s electricity imports are rising faster than exports as the domestic supply-demand position tightens. The period also included reporting that Serbia’s 18 GW connection queue is shifting renewable development toward grid capacity.
Trading coverage described Southeast Europe electricity markets splitting into three price zones, with a widening Hungary premium and solar output influencing flexibility value. Separate reporting highlighted evening tightness as a key driver of premiums across the region’s power markets. Hungarian power prices rose above €125/MWh as the Balkans decoupled on 13/7.
Further market updates pointed to Southeast European power prices moving above €150/MWh during periods of evening scarcity, with Hungary leading the surge. Reporting also said renewables eased daytime prices while evening tightness supported higher levels. Additional coverage flagged import pressure building as Hungary, Romania and Serbia increased electricity purchases.
Battery storage, renewables build-out and procurement bankability
Battery storage featured prominently in Southeast Europe market coverage, including reporting on procurement approaches where €/kWh is no longer sufficient for bankability considerations.

Deal-flow coverage also said activity is shifting from project pipelines to financeable platforms.
EBRD prepared a €30 million decision for Tenevo’s 512.5 MWh battery expansion. Greece accelerated its battery pipeline toward an operating target of 1.5 GW. GEN-I began Bulgarian battery operations with a 126 MWh SUNOTEC project.
In Serbia, reporting said the grid bottleneck is turning standalone batteries into merchant infrastructure. Other regional updates included Montenegro household electricity bills rising to €33.80 in June. Wind and solar developments during the period also included PRP Crni Vrh 1 strengthening Serbia’s renewable energy network as a strategic transmission hub.
Nuclear, hydro and oil infrastructure updates
Nuclear policy and operations were covered alongside power-market developments. Serbia set a 2035 construction target for its first nuclear project, according to reporting dated July 14, 2026.

Hydro reporting said Đerdap 3 is becoming Serbia’s Danube storage test as U.S. capital moves toward the Balkans. EPCG advanced the Otilovići hydropower project with a construction-supervision tender, while Trebinje hydropower system carried Republika Srpska’s generation during a dry spring. Djerdap 3 returned to regional planning as Serbia and Romania formalised cooperation.

Bulgaria paused a gas-capacity obligation to BOTAŞ at a level of €512,000 per day, reported on July 18, 2026. Serbia and North Macedonia moved into an expanded Vertical Gas Corridor on July 17, 2026. Serbia also prepared a €1 billion gas-network expansion with World Bank support on July 15, 2026.
TAP passed 60 bcm, as the Southern Gas Corridor expanded its European role in mid-July reporting. Azerbaijan targeted wider European gas sales while financing limits new supply, also dated July 15, 2026. Bulgaria stored Shell LNG at Chiren ahead of the winter season on July 14, 2026.
Nuclear-adjacent risk coverage tied higher TTF gas prices to increased SEE peak power risk as thermal generation rises on July 17, 2026. EU dependence on Russian LNG reached a new high before . Bosnia gas plan reporting said it puts U.S. energy diplomacy on collision course with EU rules.
LNG terminals, offshore drilling and regional policy signals
The period included LNG terminal ownership interest in Greece: Aktor sought a 50% stake in Motor Oil’s Dioryga LNG terminal on July 13, 2026. Igoumenitsa was selected as an operating base for Greece’s Block 2 offshore drilling in the same date range. North Macedonia–Greece gas pipeline remained scheduled for 2027.
Bulgaria called for ETS reform and priority status for electricity networks on July 13, 2026. Europe-wide electrification strategy coverage said targets include lower fossil-fuel imports and faster grid investment during the same date window. Separate reporting also said Europe: Brent, gas and carbon prices rose as Middle East tensions drove energy markets on July 14, 2026.
Solar build-out across the region and power-market timing effects
Solar developments included weekend output patterns affecting pricing: weekend solar output cut baseload prices but left evening scarcity intact on July 18, 2026. Greenvolt expanded Romanian commercial solar through fully financed PPAs on July 17, while Shikun & Binui commissioned a 104 MW Romanian solar project on July 16. Defic Globe paired batteries with two Romanian solar plants in the same timeframe.
The EU generation mix update said solar overtook nuclear as the EU’s largest electricity source in June on July 15, 2026. Greece revised net billing to revive solar self-consumption and storage on July 14, while Bosnia and Herzegovina’s Republic of Srpska moved to close a small-solar subsidy loophole that day too. Romania: Rezolv advanced more than 1 GW Dama solar and battery project on July 13.
Bilateral projects: cables, transmission hubs and oil pipeline procurement delays
A Black Sea interconnector update said Romania and Georgia moved a 1.3 GW cable into technical development on July 15, 2026. Transmission-related coverage also linked PRP Crni Vrh 1 to strengthening Serbia’s renewable energy network as a strategic transmission hub on July 19.
An oil infrastructure update reported that a supervision appeal delayed Serbia–Hungary oil pipeline procurement on July 16, 2026. In parallel with these infrastructure items, reporting continued to track how electricity imports and exports were changing within Serbia during the week ending July 19.
Narratives around “CBAM-ready” green power platforms and metals processing
A Serbia-focused electricity update described a verified green electricity platform that can turn wind, solar and batteries into CBAM-ready industrial value on July 14, 2026. The same date range included reporting that Serbia’s metals opportunity is moving from ore to bankable processing.
Sovereign-backed finance for renewables and hydrogen project bankability
The period included reporting that Serbia turned to sovereign-backed finance for a landmark 1.2 GW solar programme on July 15, along with coverage that Serbia’s renewable market moved from auctions to construction during mid-July. Battery storage was also described as the next bankability test for Serbia’s power market on July 14.
A separate update said Serbia’s hydrogen ambitions entered a new era of project bankability on July 14, alongside coverage of how standalone batteries are being shaped by grid bottlenecks into merchant infrastructure.
EPCG hydropower tendering and dry-spring generation transfers
EPCG advanced Otilovići hydropower with construction-supervision tendering reported on July 17, while Trebinje hydropower system carried Republika Srpska’s generation during dry spring conditions that same day.
