Romania’s renewable energy sector is increasingly moving beyond single-technology developments, with hybrid projects emerging as a key feature of the next investment cycle. A notable example is Eurowind Energy Romania’s Siminoc Hybrid Wind-Solar Park in Constanța County, which has recently secured construction permits. The project will combine 24.8 MW of wind capacity and 24.8 MW of solar capacity, creating a total installed capacity of 49.6 MW and expected annual electricity production of approximately 120 GWh. Construction is scheduled to begin in 2027, with commercial operations expected in 2028.
The project reflects a broader shift in renewable energy development across Southeast Europe. Wind and solar technologies complement each other through different production patterns, allowing hybrid facilities to improve grid utilisation, smooth generation profiles and maximise the value of existing network connections. As grid access becomes increasingly constrained across the region, hybrid projects offer a practical solution by generating more electricity from the same infrastructure footprint while reducing the limitations associated with standalone renewable assets.
The location of the project adds further strategic significance. Constanța County, situated in the Dobrogea region, benefits from some of Romania’s strongest renewable energy resources and occupies a central position within the country’s transmission network. The region is also becoming a focal point of Romania’s wider energy transformation, supported by the development of the Neptun Deep gas project and growing offshore energy ambitions in the Black Sea. In this context, the Siminoc project represents more than a renewable energy investment; it forms part of a broader restructuring of the country’s energy system.
The project is also significant within Eurowind Energy’s long-term plans to establish a 1 GW renewable portfolio in Romania. For investors, however, the central issue extends beyond the permitting of individual projects. The more important question is whether Romania’s grid infrastructure and market framework can accommodate a rapidly expanding pipeline of hybrid assets. Factors such as curtailment risk, grid connection timelines, balancing obligations and evolving market pricing dynamics will play a critical role in determining project profitability.
Siminoc also illustrates a wider trend emerging throughout Southeast Europe. Renewable projects are becoming increasingly complex, requiring multiple value layers to remain competitive and bankable. Hybrid generation, energy storage integration, secure grid access, corporate power purchase agreements and sophisticated market optimisation strategies are becoming essential components of successful developments. In contrast, standalone merchant solar projects face growing exposure to midday price compression and revenue volatility, while hybrid assets can offer greater operational flexibility and resilience.
Romania remains one of the region’s most attractive renewable energy markets, supported by strong electricity demand, access to European funding mechanisms, industrial consumption growth and the need for additional generation capacity. However, the market is entering a more demanding phase. Future success will depend less on simply connecting renewable projects to the grid and more on designing projects that actively support and integrate with the evolving power system. Developers capable of aligning technology, infrastructure and market strategy are likely to define the next chapter of Romania’s renewable energy expansion.
