Recent analysis reveals that the spike in electricity prices across Southeast Europe (SEE) in January cannot be solely attributed to demand growth. Despite notable increases in consumption—Serbia’s demand rose by 33.43%, Croatia’s by 22.42%, and Bulgaria’s by 17.51% month-on-month—the correlation between these demand figures and price movements was weak.
In Serbia, for instance, average electricity prices in January remained significantly lower than those in Romania and Hungary, indicating that local market dynamics played a crucial role. Meanwhile, Bulgaria experienced extreme daily price volatility rather than a consistent upward trend, suggesting that factors other than demand were at play.
The analysis highlights supply-side constraints as the primary influence on pricing behavior. Key factors such as hydroelectric variability, dependence on gas, and exposure to imports have proven more significant than demand fluctuations. In regions where hydroelectric generation increased sharply, prices tended to stabilize or even decrease despite rising electricity consumption. Conversely, markets where hydro resources diminished or gas became the marginal source saw price hikes irrespective of demand levels.
Trading volumes across different exchanges further illustrate this trend. Markets with robust liquidity, like HUPX and OPCOM, which recorded increases of 22.34% and 17.02% respectively, managed to price scarcity effectively. In contrast, thinner markets such as SEEPEX experienced a -12.45% decline in trading volume, reflecting a muted price response despite heightened demand and highlighting execution risks rather than an oversupply scenario.
This analysis suggests that simplistic models linking demand directly to price are inadequate for understanding the complexities of the electricity market in January. For market participants, the availability of marginal supply and strategic cross-border positioning emerged as more critical indicators than mere consumption growth.
