The Finnish wind energy service provider Arenso Oy and a leading Estonia-based renewable energy developer and producer Utilitas Wind have signed an agreement for co-operation in the Saare-Liivi Offshore Wind Park project. Arenso was assigned to prepare basic design for the project. The work was launched in February and will be completed by the end of July 2025.

The purpose of Arenso’s and Utilitas Wind’s co-operation is to prepare a Basic Design package for future design phases, permitting tasks, planning of construction work and operation.

“We believe Estonia holds great potential for offshore wind energy. Developing offshore wind power would help lower electricity prices, enhance supply security by reducing reliance on costly and polluting fossil fuels, and significantly contribute to reducing the production deficit across the Baltic region. Our collaboration with Arenso will enable us to identify the best technical solutions and advance the project according to the planned timeline,” describes Andrus Zavadskis, Member of the Board of Utilitas Wind.

“Arenso brings its proven, hands-on expertise of Northern Baltic Sea offshore wind energy to the Saare-Liivi project, laying the groundwork for a technically optimized and competitive wind farm implementation. Utilitas Wind, as a leading wind energy player in the Baltic states, is a strategically important customer for Arenso. The agreement is also a ground-breaking step in importing Finnish knowhow to offshore wind projects globally,” says Esa Holttinen, Business Director at Arenso Oy.

Utilitas Wind is moving forward with the planning and design activities of the Saare-Liivi offshore wind farm, and approximately 80 wind turbines are planned to be erected in the first stage of the development. The total capacity will be 1,200 megawatts and the expected annual electricity production will exceed five terawatt hours. The project is co-funded by The European Climate, Infrastructure and Environment Executive Agency.
