Wind power is increasingly emerging as a stabilising force in South-East European electricity markets, providing a counterbalance to solar-driven volatility and reshaping the role of flexible generation.
In week 16, wind output across the region rose to 3,047 MW, representing a 1,143 MW increase week-on-week and placing generation 23% above seasonal norms. This surge played a critical role in compressing regional price spreads, particularly between Hungary and Germany.
Unlike solar, which peaks during midday hours, wind generation often contributes more significantly during evening and overnight periods, when system demand remains relatively strong. This complementary production profile enhances its value within the generation mix, particularly as solar capacity continues to expand.
The impact on pricing is notable. Increased wind output reduces reliance on gas-fired generation during peak hours, limiting price spikes and smoothing intraday volatility. In effect, wind is increasingly acting as a natural hedge against the “duck curve” dynamics created by solar generation.
From an investment perspective, this is driving a reassessment of relative asset value. Wind projects are beginning to achieve higher capture prices compared to solar, due to their alignment with higher-priced hours. This is likely to influence capital allocation decisions, particularly in markets where both technologies are competing for grid access and financing.
Key regions for wind development include Romania’s Dobrogea region, Serbia’s Banat corridor, and coastal areas of Croatia and Greece. Repowering of older wind assets is also gaining attention, offering opportunities to increase output without significant new grid constraints.
The strategic role of wind is expected to strengthen as the energy transition progresses. While solar will continue to dominate capacity additions, wind’s ability to provide generation during critical demand periods positions it as an essential component of system stability.
