Eurowind Energy Receives Permits to Build a 49.6 MW Hybrid Power Plant in Romania

Eurowind Energy Romania, the Romanian subsidiary of the Danish renewable energy group Eurowind Energy, has obtained construction permits for solar and wind power facilities as part of the Siminoc hybrid energy project in Constanța County, south-eastern Romania.

The project will become Eurowind Energy Romania’s first hybrid wind and solar power plant. Its total installed capacity will amount to 49.6 MW and will be evenly divided between the two components: approximately 24.8 MW of wind capacity and a further 24.8 MW of photovoltaic capacity.

The estimated investment volume is €65 million. The project is supported by Romania’s Contracts for Difference (CfD) scheme, which is intended to provide long-term investment predictability and facilitate its stable implementation.

According to the company’s estimates, the hybrid power plant will generate around 120 GWh of electricity annually. This will be sufficient to cover the yearly consumption of more than 50,000 households.

The receipt of construction permits marks the completion of an important administrative stage of the project. Construction is scheduled to begin in 2027, while commissioning is expected in 2028. The final timetable may be adjusted depending on grid connection procedures and other administrative conditions.

During the procurement stage, the company also plans to determine the configuration of a battery energy storage system (BESS). Combining wind and solar generation with storage facilities will make it possible to align electricity production more closely with demand, reduce local fluctuations in generation and improve the resilience of the energy system.

Adrian Dobre, Head of Eurowind Energy Romania, stated that the company intends to integrate energy storage systems into all its projects. Eurowind Energy Romania’s strategic objective is to reach 1 GW of capacity by 2030 and implement an investment programme worth approximately €1 billion over the next four years.

Eurowind Energy has been operating in the Romanian market since 2011. The company’s portfolio includes four operational solar power plants — Hălchiu, Măgurele, Pufești and Teiuș — as well as projects with a combined capacity of around 7.5 GW at various stages of development. By the end of the second quarter of 2026, the company’s operational capacity in Romania is expected to reach 184 MW, including 60 MW of BESS capacity in Teiuș.

Comment by Experts of the Institute of Danube Research

The receipt of permits for the construction of the Siminoc hybrid power plant is an important indicator of the transformation of Romania’s energy model. This is not only a matter of increasing the share of renewable energy, but also of shifting towards comprehensive solutions that combine different generation sources with energy storage systems.

The location of the project in Constanța County is particularly significant for the Black Sea–Danube Region. Dobruja is already one of Romania’s key centres for wind energy development. The further expansion of hybrid capacity may strengthen regional energy resilience, support infrastructure development and create additional opportunities for cross-border energy cooperation.

Experts of the Institute of Danube Research note that this experience is especially relevant for Ukraine in the context of the future reconstruction of its energy system. Combining solar and wind generation with battery storage facilities can become an effective tool for improving the energy security of communities, particularly in the southern regions with substantial renewable energy potential.

The use of the CfD mechanism is also important, as it reduces investment risks and creates more predictable conditions for implementing large-scale energy projects. This approach deserves attention when designing instruments to attract private capital for the reconstruction and modernisation of Ukraine’s energy sector.
