Electricity.Trade analysis of the January–February 2026 project pipeline confirms that onshore wind across South-East Europe has re-entered a phase of disciplined expansion, focused less on headline capacity growth and more on seasonal system value. New and expanded wind projects in Montenegro and Greece illustrate how wind has become a critical winter stabilizer across SEE power markets, even as structural limitations prevent it from displacing gas as the marginal price setter during stress.
The most advanced project signal in the region is the Gvozd 2 wind farm expansion in Montenegro, scheduled for completion toward the end of 2026. The expansion will lift total installed capacity at the Gvozd site to 75.6 MW, with expected annual generation of approximately 210 GWh, enough to supply more than 35,000 households. Crucially, the project is not being developed as an isolated addition but as a continuation of an existing operating asset, allowing developers to leverage established grid connections, access roads, and operational expertise. This reflects a broader regional preference for brownfield and extension-type wind investments, where permitting and execution risk is materially lower than for greenfield projects.
From a system perspective, Gvozd 2 matters less for its absolute megawatts than for its seasonal profile. Montenegro’s electricity system is hydro-heavy but exposed to hydrological volatility. Additional winter-weighted wind output provides diversification precisely during periods when hydro inflows are weakest. Electricity.Trade notes that this seasonal complementarity explains why wind remains strategically attractive even in markets where average prices are increasingly compressed by solar during summer months.
Greece’s wind pipeline represents the largest near-term volume expansion in the region. During 2025 alone, Greece added approximately 340 MW of new wind capacity, representing around EUR 420 million in investment. Beyond this, a further 1.1 GW of wind projects is currently under construction or contractually secured, with the majority expected to come online within the next 12 to 18 months. This renewed acceleration follows several years of permitting bottlenecks and grid congestion challenges, which had temporarily slowed development.
Electricity.Trade analysis highlights that Greece’s wind resurgence is closely tied to market reform and grid planning. New wind projects are increasingly sited in regions with improved export capability or co-located with other renewables, reducing curtailment risk. However, despite this progress, Greece continues to face a structural limitation: wind output variability remains high, and system flexibility has not scaled at the same pace as installed capacity.
Across SEE, wind’s impact on price formation follows a consistent pattern. During sustained high-wind periods, particularly in winter, wind generation suppresses peak prices and reduces the call on gas-fired units. In January 2026, wind availability contributed to moderation of peak pricing in several markets during specific hours. However, once wind output declines or forecast uncertainty increases, systems revert rapidly to gas and imports. The transition is abrupt, not gradual.
This behavior underscores a central structural reality. Wind improves energy adequacy but does not guarantee capacity adequacy at the margin. Without sufficient storage or fast-ramping demand response, wind cannot be relied upon to meet sudden demand spikes or compensate for cross-border congestion events. As a result, gas remains indispensable as the marginal balancing resource.
Another constraint lies in grid integration. In Bulgaria and parts of Greece, nuclear and coal baseload limit downward flexibility during high wind output, occasionally forcing curtailment or exports. In lower-wind periods, the same inflexibility exacerbates reliance on imports and gas. Wind therefore interacts with legacy baseload assets in ways that sometimes dampen, and sometimes amplify, volatility.
From a financing perspective, the wind projects referenced in the document increasingly rely on contracted revenue structures, including long-term power purchase agreements and support schemes. This reduces merchant exposure for developers but does not alter system-level marginal dynamics. For traders, this distinction is critical: wind stabilizes producer revenues without necessarily stabilizing market prices.
Electricity.Trade concludes that wind’s role in SEE has matured into that of a seasonal stabilizer rather than a structural price-setter. Its value is highest during winter months and during sustained weather regimes. Its limitations emerge during rapid transitions, forecast errors, and peak stress events. Until wind deployment is matched by comparable growth in flexibility, its capacity to reshape marginal pricing will remain constrained.
