Between August 24 and August 30, 2026, 89 articles were published across electricity, gas, markets, nuclear, oil, solar, trading, hydro and wind coverage. The period’s most-read items included Slovenia’s grid-modernisation support increase to €58.66m and Montenegro’s €50 million Velestovo solar-BESS project securing grid access. Other widely read stories covered CBAM-related changes for electricity exporters and trading dynamics affecting Southeast Europe’s power prices.
Electricity system updates and market price moves
Serbia’s generation stack absorbed a 13.5% load increase while preserving export capacity on August 30, 2026. Serbian power prices stayed above €150/MWh as evening peaks surged on August 29, 2026, with Serbia also holding a €22/MWh discount to Hungary despite stronger domestic demand on August 30, 2026. In Slovenia, electricity production fell by 9% as hydro and thermal output declined on August 26, 2026, while the Slovenia power balance tightened on August 28, 2026 as hydro output slumped and demand rose.
In North Macedonia, power output fell as the utility advanced its solar transition at coal sites on August 29, 2026, following a reported 13% fall in June electricity production on August 26, 2026. Bosnia and Herzegovina reported that FBiH July electricity output fell as coal production contracted sharply on August 28, 2026, and also that FBiH power output fell as brown coal production dropped almost 30%. Albania’s power output increased by 34% on August 28, 2026, supported by hydro recovery that strengthened its export balance.
The Danube drought was linked to pressure on regional systems as nuclear output fell on August 29, 2026. Romania turned to demand response and coal as drought sidelined nuclear generation on the same date. In parallel, Bosnia said CBAM changes could save electricity exporters €13 million a year on August 29, 2026, while other reporting highlighted how CBAM verification requirements affect hourly evidence for non-EU producers.
Nuclear and hydrology impacts across the region
Bulgaria reduced Kozloduy unit 5 to 850 MW, with Danube drought pressure cited as a driver on August 28, 2026. Bulgaria also weighed Danube protection works after low water exposed Kozloduy nuclear risk on August 25, 2026. Hungary’s Paks nuclear output recovered as Danube conditions improved on August 26, 2026.
Northern hydrology-related reporting included North Macedonia turning to Crni Drim refurbishment to extend its hydro fleet for decades on August 25, 2026. Bosnia and Herzegovina saw Višegrad hydropower output fall sharply in July on the same date. These updates were part of a broader set of system developments tied to water availability and generation constraints.
LNG and pipeline gas developments in Southeast Europe
Croatia’s Krk LNG terminal received its first Norwegian cargo on August 29, 2026. Bulgaria’s Bulgargaz sought a 5.5% September price rise as its supply mix became more expensive on August 28, 2026. Europe entered the final gas filling stretch with storage at a seasonal low last seen over the past
The same period included reporting that Serbia–North Macedonia gas link moved towards execution as a southern supply route took shape on August 28, 2026. Bulgaria’s Bulgargaz moved into regional LNG logistics from the
A separate set of updates covered infrastructure planning: Serbia prepared a reported €1 billion gas network modernisation centred on Niš on August 26, 2026, while North Macedonia prepared September entry into the Vertical Gas Corridor. Greece moved to turn Revythoussa into a regional LNG bunkering hub on August 26, 2026.
Tightness signals in day-ahead power trading and cross-border markets
Southeast European day-ahead power prices plunged as renewables surged while Romania turned exporter status was reported for August 28, 2026. Spot prices retreated on solar surge during the following day range but Serbia and Albania bucked the regional trend. On the same timeline of market moves, reporting described SEE spot price dynamics shifting around liquidity conditions and trading structures.
The period also included analysis of how trading windows changed: SEE’s evening price ramp was described as becoming one of the region’s most valuable trading windows on August 30, 2026, while SEE power prices rose despite falling regional demand as supply tightness took control. Another reported driver was wind shortfall becoming the main renewable factor behind SEE’s August price rally. In Greece specifically, a reported 41% wave in power prices was linked to losing wind generation.
{{EXTLINK_0}} Coal moved back up the SEE merit order as expensive gas lost generation share on August 30, 2026, alongside reporting that gas burn fell by 30% but TTF still set a risk premium for SEE electricity. Additional market coverage addressed CBAM-related verification requirements for non-EU producers across hourly evidence chains.
Solar projects, BESS-linked developments and wind financing under CBAM scrutiny
A series of solar and storage-linked developments ran through the week. Montenegro’s Velestovo secured a grid connection agreement for its reported 60 MW /solar project with BESS elements associated with a total project value of €50 million, reported around late August. Romania’s energy pipeline included a plan by “4P” for a reported €500m /solar-storage portfolio with a stated capacity of 1.8 GWh BESS , while MVM advanced a separate Romanian solar project valued at reported € 16m .
Croatia also saw solar support through technical assistance mobilising reported € 50m for “ 64 MW
{{EXTLINK_1}} In wind coverage, an EPC-financing tender worth reported € 95.6m went out via ERS in Bosnia and Herzegovina to revive a reported “ 60 MW Hrgud
{{EXTLINK_2}} Offshore wind planning in Romania identified Black Sea zones for reported “ 3.1 GW
{{EXTLINK_3}} Wind financing also included Scatec securing financing for a reported “ 77 MW
Nuclear-linked drought measures alongside oil logistics changes
The drought-linked nuclear constraints were paired with policy responses in Romania that referenced emergency Danube measures during Cernavoda shutdown tests aimed at system resilience testing. In oil logistics, NIS sought a new US waiver as its Pančevo refinery raised processing levels and completed rail upgrades on August 29, 2026. Serbia also prepared a second crude supply corridor ahead of an NIS waiver deadline approaching on August 27, 2026.
Bulgaria’s Burgas refinery lifted output and profit as liquidity pressure eased on “ August 27, 2026 . Lukoil’s Petrotel refinery sought insolvency protection while pursuing restart on “ August 26, 2026 , while the US extended the window for Lukoil international asset sale on “ August 25, 2026 .
Batteries in CBAM accounting and flexibility market openings in electricity policy
Batteries were highlighted as complicating CBAM electricity verification because storage breaks direct generator-to-buyer lines in evidence chains. Related coverage described CBAM turning renewable electricity exports into an hourly evidence business for non-EU producers. Solar power’s CBAM advantage was framed around producers proving every hour of relevant data.
A parallel policy track focused on flexibility markets: Romania opened its electricity market to paid demand reduction with a crisis-only constraint opening described for late August. Electrica turned Craiova heat transition into an “ 82 MW flexibility plant
