AFRY Netherlands has won a contract worth over EUR 3 million for offshore wind farm design in Estonia at a tender launched by Enefit Green for its Liivi project in the Gulf of Riga.
The contract, signed on 6 January, according to a public tender award notice, involves preparing a Contract for Difference (CfD) Front End Engineering Design (FEED) with CapEx, OpEx and Levelised Cost of Energy (LCoE) assessment, or Bid FEED, as well as advising on a pre-agreed hourly rate for up to three years on changing one-off works or orders to Bid FEED and additional services.
The Liivi Bay offshore wind farm is planned to be built in the Gulf of Riga, 11 kilometres from Kihnu Island and 16 kilometres from Häädemeeste. Enefit expects the construction period of the offshore wind farm to take place between 2028 and 2030.
The offshore wind farm is planned to consist of up to 84 turbines and to have a total generation capacity of 1,000 MW, with an annual electricity production of up to 4 TWh. Besides feeding electricity into the Estonian grid, the project is also planned to be interconnected with the Latvian national grid.
Enefit Green acquired full ownership of the 1 GW Liivi offshore wind farm from Eesti Energia, the state-owned energy company and Enefit’s majority owner, in March 2023.
According to the project’s website, the analysis of the technical solutions for the wind farm was completed at the beginning of 2023, with a conceptual design prepared by BLIX Consultancy.
The environmental impact assessment (EIA) programme for the 1 GW project was approved in 2021, and the EIA surveys at the site in the Gulf of Riga started in 2022 with the first seabed surveys, wind measurements, and bird surveys already carried out.
In December 2024, Enefit Green published findings of an environmental impact assessment (EIA) performed by Estonian consultancy Skepast and Puhkim, that said the 1 GW project would have no significant negative effects on the environment while boosting labour market activity and municipal revenues.
