Romania Renewable Energy - Market Share Analysis, Industry Trends & Statistics, Growth Forecasts (2026-2031)

The romania renewable energy market size is expected to grow from 17.73 gigawatt in 2025 to 19.24 gigawatt in 2026 and is forecast to reach 28.96 gigawatt by 2031 at 8.52% CAGR over 2026-2031. This report is Segmented by Technology (Solar Energy, Wind Energy, Hydropower, Bioenergy, Geothermal, and Ocean Energy) and End-User (Utility, Commercial and Industrial, and Residential). The Market Sizes and Forecasts are Provided in Terms of Installed Capacity (GW).

Romania Renewable Energy Market Trends and Insights

Accelerated EU-funded Grid Modernisation Pipeline

EUR 815 million from the EU Modernisation Fund is earmarked to unlock renewable connections, and Transelectrica broke ground on the EUR 134 million 400 kV Constanța Nord-Medgidia Sud line in 2024, an asset sized to relieve at least 273 MW of constrained wind capacity. The project is the first in a series of high-voltage reinforcements that collectively aim to add more than 2 GW of transferable capacity by 2026. Parallel smart-grid rollouts and 29 transmission-station solar retrofits further digitalize the network, reducing curtailments. These upgrades directly bolster the Romania renewable energy market by compressing interconnection timelines and stabilizing wholesale prices. In concert with national plans for 40 GW of total installed capacity by 2035, of which 80% must be renewable, modernized lines bridge resource hubs with demand centers, enabling future offshore wind injections.

Surge in Corporate PPAs from Energy-Intensive Exporters

Industrial exporters are shifting their procurement models to secure green electricity and avoid looming carbon-border tariffs. The landmark OMV Petrom-DRI solar PPA, signed in 2024, covers approximately 100 GWh annually for 8.5 years. Saint-Gobain followed with an 800 GWh wind deal effective 2026, while Bekaert inked a 100 GWh virtual PPA with Rezolv Energy, ensuring 10-year price certainty. These contracts diversify revenue streams for developers, derisk project financing, and expedite final investment decisions. PPA momentum enhances demand visibility, increasing the confidence of institutional investors in funding large pipelines, which in turn is expected to expand the Romania renewable energy market.

Transmission Bottlenecks in Dobrogea Wind Corridor

Romania’s highest-yield wind sites in Dobrogea are limited by saturated 220 kV lines that restrain roughly 500 MW of potential additions. Curtailments reach 8% during windy nights, denting project economics. Developers face higher debt-service cover ratios and a slower financial close. Until the Constanța Nord-Medgidia Sud backbone and companion 400 kV loops enter service, grid access queues lengthen, depressing the near-term CAGR in the Romanian renewable energy market.

Other drivers and restraints analyzed in the detailed report include:

• Post-Coal Land Repurposing for Mega-Solar Parks
• Black Sea Offshore-Wind Roadmap (3-7 GW by 2035)
• Policy Volatility Around Price Caps & CfD Rollout

Segment Analysis

Hydropower retained a 44.85% share of the Romania renewable energy market in 2025, buoyed by 6 GW of installed dams straddling the Carpathian rivers. Solar, however, delivered the steepest trajectory, climbing 59% year-on-year and pushing cumulative photovoltaic capacity to 5.3 GW. Within the Romania renewable energy market size for technologies, hydropower accounted for roughly 7.95 GW in 2025, whereas solar is projected to surpass 13.2 GW by 2031. Generous CfD ceilings of EUR 78/MWh, smarter inverters, and simplified one-stop permitting offices in seven counties underpin a 14.26% CAGR for solar. Wind holds a steady second position, with onshore pipelines of 4.6 GW and the landmark offshore regime offering longer-dated expansion vectors. Bioenergy relies on EU rural development grants to monetize crop waste, and pilot plants in Dolj County are testing the co-digestion of manure and straw. Although ocean energy remains embryonic, the Black Sea's mild tidal range may suit point-absorber wave devices post-2030, thereby extending the diversity of technology.

The Romania renewable energy market benefits structurally from solar's short construction cycle, making it the preferred hedge against policy swings. Nevertheless, the dominance of hydropower ensures a year-round baseload that tempers volatility, boosting investor confidence. Pumped-storage upgrades at Tarnița-Lăpuștești could add 1 GW of storage-enabled flexibility by 2029, magnifying the integration of variable renewables. Hybrid solar-plus-wind plus battery offerings emerge in Constanța County, offering sub-60 EUR/MWh levelized costs and attracting corporate offtakers. Over the forecast window, solar's share of Romania's renewable energy market size is expected to narrow the gap with hydropower as land-repurposed mega-parks in Gorj and Hunedoara come online.
