Curonian Nord

The Lithuanian National Audit Office completed a review of the Curonian Nord offshore wind project, identifying procedural issues in its development that Ignitis Renewables fully accepted. Following the audit, the company implemented the recommendations, including transferring all Curonian Nord-related assets and contracts into a dedicated project company, while continuing to pursue a construction permit by 2027.

Ignitis Renewables, together with the Coastal Research and Planning Institute, completed the Environmental Impact Assessment (EIA) report for the Curonian Nord offshore wind farm and the associated "Plote D" export cable and made it publicly available from 14 October to 10 November 2025. The report is under review by Lithuania’s Environmental Protection Agency, which will take the decision on the environmental acceptability of the planned activities.

Public consultation on the Environmental Impact Assessment (EIA) report for the Curonian Nord offshore wind farm and the Plote D export cable began on 14 October 2025, with the documentation available for inspection at multiple municipal offices in Palanga, Neringa, Klaipėda, Klaipėda district and Kretinga, as well as online. A hybrid public meeting was held in Palanga on 11 November 2025 with additional remote participation locations, allowing residents to learn about the findings, ask questions and submit comments to the Environmental Protection Agency and the EIA preparer.

On 10 October 2025, Ignitis Renewables signed a sale and purchase agreement to acquire Ocean Winds’ 49% stake in the Curonian Nord offshore wind project company UAB "Offshore wind farm 1", following approval by Lithuania’s National Energy Regulatory Council. Ignitis will pay a nominal price for the shares and reimburse Ocean Winds for directly incurred project-related costs, giving Ignitis Renewables full control of Curonian Nord while it continues preparatory work towards obtaining a construction permit in 2027 and selecting a new partner ahead of FID.

Between June and September 2025, Wood Mackenzie conducted and finalised an independent three‑month assessment of the Curonian Nord offshore wind project for Ignitis Group, benchmarking its timeline, investment assumptions and risk management against 21 comparable European offshore wind projects and using its proprietary offshore wind database to evaluate project feasibility and development expenditures for 2023–2025.

Wood Mackenzie completed an independent three‑month assessment of the Curonian Nord offshore wind project in September 2025, having been mandated by the Ignitis Group Supervisory Board to review the project’s development expenditures, assumptions, risks and timelines against global offshore wind benchmarks.

By 30 May 2025, Environmental Impact Assessment documentation for the development of the Curonian Nord offshore wind farm and installation of the electricity export cable for offshore wind farm "Area D" in the Lithuanian sector of the Baltic Sea had been prepared to the extent that Annex 8, an underwater noise propagation modelling report, was issued. The annex details numerical modelling of underwater noise from pile‑driving for the planned Curonian Nord marine wind farm and associated offshore interconnection grid, providing the technical basis for assessing impacts on marine mammals and fish as part of the project’s EIA, which covers both the generation asset and its offshore export cable system.

Ignitis Group stated on 18 March 2025 that it had invested around EUR 50 million in the Curonian Nord offshore wind project, comprising a EUR 20 million development fee and approximately EUR 30 million allocated to environmental impact assessment, wind, water and meteorological measurements, seabed surveys and other preparatory works. The company noted that much of this spending relates to studies and data that can be flexibly used in the future without time constraints.

In 2024, Ignitis Renewables started wind and metocean measurement campaigns at the Curonian Nord site, initiating long-term offshore resource and environmental monitoring as part of the project’s development and environmental assessment workstreams.

By 2024, the Curonian Nord project had completed its main geophysical surveys at the Baltic Sea site, as indicated in the project timeline, providing seabed and site-characterisation data to support the environmental impact assessment and detailed design.

By 2024, geotechnical surveys for Curonian Nord were completed, delivering soil and sub-seabed information needed for foundation and cable design, as recorded in the project’s official timeline.

In 2023, Ignitis Renewables and Ocean Winds established a joint venture structure to develop the 700 MW Curonian Nord offshore wind farm and together secured the project’s development rights in Lithuania’s first offshore wind auction. The partnership is leading development of the country’s first commercial offshore wind farm in the Baltic Sea, with Curonian Nord expected to supply around 3 TWh of electricity per year, equal to roughly a quarter of current Lithuanian power demand.

In 2023, Ignitis Renewables, in joint venture with Ocean Winds, secured the development rights for the 700 MW Curonian Nord offshore wind farm in Lithuania’s first offshore wind auction, effectively granting the consortium the seabed and development lease for the project area in the Baltic Sea.

On 15 March 2023, the Lithuanian Government, by Resolution No. 171, approved a specific 119.5 km² maritime area in the Baltic Sea for the Curonian Nord offshore wind farm and its associated infrastructure, including export of generated electricity to the onshore network at the 330 kV Darbėnai switchyard in Kretinga district. This decision formally designated the offshore development zone for the project.
