Hydropower and electricity pricing also drew significant attention. Bosnia and Herzegovina’s Višegrad hydropower output fell sharply in September, according to an October 13 report. In the same timeframe, SEE electricity market coverage highlighted Serbia recording the highest prices as the Hungarian-German spread widened and regional import dependence persisted on October 13.
Nuclear and oil sector updates in Romania and Slovenia
Romania reconsiders the Doicești small nuclear reactor project as more than 80% of conditions remain unmet, with the development dated October 13, 2026. In Slovenia, the Krško nuclear plant missed its September generation target despite producing more than last year, according to an October 16 report.
Romania also advanced corporate changes in its oil sector. Romania approved the sale of a NIS subsidiary to Argenta as the Serbian oil group restructures under sanctions pressure on October 16, 2026.

Gas storage, winter security and renewable gas projects
Gas coverage during the period focused on storage security and wholesale pricing. Hungary built a 96-day winter gas reserve as storage strengthens energy security on October 16, 2026. Bulgaria cancelled a €56 million tender for Chiren gas storage after drilling bids exceeded budget on October 15.
Bulgargaz sought a 34% wholesale gas price increase as Bulgaria faced higher supply costs on October 15, 2026. A World Bank package supported a €175 million Serbian gas network upgrade on October 12, while OMV Petrom’s refining strength offset declining oil and gas output on the same date.
The wider supply environment was also reflected in reporting that Europe’s lower gas stocks increased dependence on winter LNG deliveries on October 12. Greece opened nearly a €1 billion energy-investment window as EU fiscal flexibility was approved on October 12.
Electricity demand shifts and grid investment across the region
Electricity reporting covered demand changes alongside grid upgrades supporting renewable expansion. Romania completed a €51 million grid stability upgrade nine months early to support renewable expansion on October 16, while Romania’s electricity demand fell by 4%. The same report stated solar generation rose nearly 48%, with net imports narrowing.
Croatia’s electricity reform opened a new market for aggregators, grid-access engineering and connection-rights trading on October 17. Croatia’s electricity output rose 13% in August but import dependence persisted, according to an October 16 update.
Bulgaria’s electricity exports rose by 62% as solar and storage expanded on October 12. Montenegro reported that household electricity bills fell in September despite higher annual consumption on October 13.
Nuclear shortages, wind variability and trading price moves
Southeast European market coverage described price swings linked to generation patterns and cross-border flows. Serbia power prices plunged by 25%, but Romanian and Bulgarian nuclear shortages kept markets divided on October 12. Another report said SEE electricity prices surged above €250/MWh as Romania reversed into imports and regional trading spreads widened on October 15.
A separate trading update noted SEE electricity prices diverged by nearly €100/MWh, with Greek renewable surge cutting regional imports while Serbia faced higher costs on October 14. On October 16, coverage stated southeast European electricity prices surged as wind output fell, imports increased and Serbia led the regional market.
The period also included data centre grid constraints: Greece’s 9 GW data centre connection queue raised grid allocation pressure on October 12. Trading activity in Albania was reflected in reporting that ALPEX electricity trading rose by 76% in September as regional market activity expanded on October 14.
Renewables buildout: solar-battery deals, wind approvals and PPAs
The renewables pipeline included solar-battery projects with contracted offtake terms. Enery started a Slovenian solar-battery project with an €88/MWh municipal offtake agreement on October 15. Alerion completed a 32 MW Romanian solar plant as Parapet expanded its EPC portfolio across southeastern Europe on the same date.
Bilateral developments continued across wind projects and grid connections. Serbia’s Kovačica wind complex expanded towards 200 MW, supported by a €140 million Pupin investment reported on October 16. Montenegro cleared an 88 MW Korita wind farm for construction as investment shifted towards grid connection also on October 16.
Bosnia advanced wind permitting: its Tolanovo, a € 102 million project advanced to concession stage while grid access became key investment hurdle on October 15. Hungary targeted more than 6 GW of wind capacity by 2040, aiming to reduce electricity import dependence on October 14.
PPA routes and CBAM-linked contract adjustments for Balkan exporters
The period also covered contract structures for renewable revenue in Serbia and Montenegro. Domestic industrial PPAs gave Serbian and Montenegrin renewables another route to revenue on October 18, while Montenegro electricity exporters needed stronger PPAs to secure Italian market revenues that same day. Serbian renewables faced an export contract test on the Hungary corridor reported for October 18.
Certain policy developments were linked to how trades are financed into the EU market under carbon border rules. CBAM turned Balkan electricity spreads into a carbon and credit trade on October 18, while CBAM rewrote Balkan electricity contracts as exporters sought a bankable route into Europe that day. EU recognition of Western Balkan renewable certificates could strengthen PPAs without replacing CBAM verification, according to an Oct
