Romania’s renewable market is shifting from single-technology projects toward hybrid generation. Eurowind Energy Romania’s Siminoc Hybrid Wind-Solar Park in Constanța County is a clear example. The project has received construction permits and will combine 24.8 MW of wind capacity with 24.8 MW of solar capacity, for a total of 49.6 MW, with expected annual production of about 120 GWh. Construction is planned for 2027, with commissioning scheduled for 2028.
The project reflects the logic now shaping renewable development across SEE. Wind and solar have different production profiles, and combining them can improve grid utilisation, smooth generation and strengthen the economics of a single connection point. In markets where grid access is becoming more constrained, hybridisation is increasingly attractive because it allows developers to produce more useful energy from the same infrastructure envelope.
Constanța County is also strategically relevant. The Dobrogea region has strong renewable resources and sits close to important transmission routes and the Black Sea energy system. Romania is already preparing for the arrival of Neptun Deep gas and broader offshore energy infrastructure. Hybrid renewable projects in this region therefore sit inside a wider energy transformation, not an isolated green-power story.
Eurowind’s ambition to build a 1 GW Romanian portfolio places Siminoc inside a broader development pipeline. For investors, the important question is not whether individual projects can be permitted, but whether Romania’s grid and market rules can absorb a much larger hybrid portfolio. Curtailment, connection delays, balancing responsibility and price cannibalisation will all shape returns.
The Siminoc project also points to a regional trend. SEE developers are learning that bankable renewable projects increasingly need several layers: hybrid technology, storage potential, grid certainty, corporate offtake and market optimisation. A simple merchant solar plant is becoming more exposed to midday price compression. A hybrid wind-solar asset has more resilience.
Romania’s renewable market is still attractive because it offers scale, EU funding channels, industrial demand and rising power-system needs. But the easy phase is ending. The next phase belongs to developers that can design projects around the grid, not merely connect projects to it.
