Croatia’s electricity market weakened in Week 24, but its underlying generation dynamics differed markedly from most other Southeast European systems. The Croatian day-ahead average declined by 7.3% to €92.02/MWh, placing the market broadly in line with Greece at €91.53/MWh and Bulgaria at €93.58/MWh, and firmly within the regional mid-price range.
Electricity demand increased by 3.9% to 311.46 GWh, tracking the wider seasonal shift toward higher summer consumption across Southeast Europe. However, the supply-side structure evolved in a more distinctive way compared to neighbouring markets, particularly in renewables.
Variable renewable generation fell sharply, with output declining by 35.9%, making Croatia the only analysed market to record a significant contraction in wind and solar production. The decline was primarily driven by weaker wind conditions, which reduced the contribution of low-cost renewable supply during the week.
This shortfall was offset by a strong hydropower response. Croatian hydro generation increased by 43.5%, or 10.1 GWh, marking one of the most pronounced hydro recoveries in the region. This shift created a balancing structure that differed from countries such as Serbia, Bulgaria, and Türkiye, where hydro output weakened and thermal generation absorbed a larger share of system adjustment.
Croatia’s external position also showed mild improvement. Net electricity imports declined by 8.9%, indicating that stronger hydro generation helped reduce reliance on cross-border supply despite weaker renewable wind conditions. LNG inflows remained broadly stable at 640.83 GWh, declining only slightly by 0.7%, suggesting no major change in the country’s gas supply balance.
From a market perspective, Croatia’s case highlights the importance of hydrological variability as a primary pricing driver. Unlike the broader regional narrative dominated by rising wind and solar output, Croatia’s price movement was shaped more by hydro availability than by renewables, underscoring the diversity of balancing mechanisms across Southeast Europe.
For traders and industrial consumers, Croatia remains a market where price formation can shift rapidly depending on hydrology, wind conditions, and cross-border flows. Week 24 demonstrated that even in periods of weak renewable output, stronger hydro conditions can stabilize the system and support lower wholesale prices.
