Offshore Wind Romania: Black Sea Perimeters Approved — NRG-IA

A potential of 3.1 GW in the Black Sea: the Executive's decision details The Romanian Government approved offshore wind perimeters in the Black Sea targeting 3.1 GW. This decision officially initiates the administrative procedures for Romania's first utility-scale marine wind capacities. According to Economedia, the government decision clearly establishes the geographical coordinates of the zones within the Romanian sector of the Black Sea that will be offered for concession to private investors through competitive bidding. The concession processes will be structured as public auctions, where international consortia will compete based on technical capability, financial strength, and their plans for local supply chain integration. As reported by e-nergia, harnessing this sector is expected to generate a significant economic boost, attracting billions of euros in investments to port infrastructure and industrial manufacturing units in the Dobrogea region. The delineation of these perimeters represents the first filter in a complex authorization process. Projects will be developed in successive phases, starting with on-site wind measurements and detailed geotechnical surveys, which are essential for determining the type of foundations required in the Black Sea basin, where depths increase relatively quickly from the shoreline. The offshore law and maritime spatial planning: how we got here This administrative step is a mandatory procedural milestone under the specific offshore wind energy legislation recently enacted by the Romanian Parliament. Economica.net reports that the approval of the perimeters list follows extensive inter-institutional consultations and technical assessments designed to identify areas with optimal wind resources while safeguarding other economic and security activities. The Ministry of Energy coordinated the design of these blocks to avoid overlaps with strictly regulated commercial shipping lanes, military exercise zones used by the Naval Forces, and active natural gas exploration perimeters, such as the Neptun Deep project. Environmental constraints were also factored in, avoiding marine protected areas to minimize the impact on avian and aquatic biodiversity. Without this clear maritime spatial planning by the Romanian state, no competitive bidding process could have legally commenced, and investors would have lacked the legal certainty required to allocate massive pre-development budgets. The approved decision removes a major uncertainty from the agenda of Europe's largest utility developers. The grid integration challenge: Dobrogea is already congested Integrating over 3,000 MW of offshore wind power into the National Power System (SEN) presents a massive technical challenge for the transmission system operator, Transelectrica. Unlike onshore wind farms, marine installations generate massive, concentrated power flows that require high-capacity coastal substations and new high-voltage transmission lines. The Dobrogea region is already one of the most congested energy zones in Eastern Europe, hosting the Cernavoda Nuclear Power Plant and over 3,000 MW of existing onshore wind and solar capacities. During periods of peak generation, the current grid operates close to its technical transmission limits to transport power to major consumption centers in the west and south of the country. In NRG-IA's editorial view, the commercial success of these marine blocks will not be decided solely by developer interest in concessions, but by the Romanian state's ability to guarantee grid connection. If Transelectrica's major transmission infrastructure projects—including the high-voltage direct current (HVDC) cable planned to cross the country from east to west—are not completed on time, the new offshore capacities risk facing severe curtailments. Next critical steps: auction timeline and the CfD support scheme The next critical milestone is drafting the detailed tender specifications and officially launching the public auctions for the approved perimeters. While authorities estimate that the first auctions could be launched in the near future, the actual development of an offshore wind farm—from obtaining licenses to commissioning—typically takes 5 to 7 years in Europe. Investors will closely monitor regulatory stability and the architecture of the financial support scheme through Contracts for Difference (CfD), which is considered vital for making these highly complex projects economically viable. Without a long-term guaranteed strike price, the massive upfront costs of offshore technologies could deter major global players from participating. Any delay in defining these financial mechanisms or obtaining environmental permits will postpone the moment when the first marine turbines feed electricity into the Romanian grid, putting pressure on the decarbonization targets Romania has committed to for 2030.
