Tuul Energy is pleased to announce that the Environmental Impact Assessment (EIA) program for its offshore wind farm project has been officially approved by the Estonian Consumer Protection and Technical Regulatory Authority (CPTRA).
This marks a crucial step for Tuul Energy project, a joint initiative between Norwegian developer Deep Wind Offshore, French renewable energy company VALOREM, and Estonian-based Sunly. Together, they aim at developing an offshore wind farm with a potential capacity exceeding 1 GW, which would be a significant step toward Estonia’s green energy future.
Now the planning of environmental studies will proceed according to the program, along with the impact assessment. Community engagement and the development of cooperation projects in Saaremaa will also continue, with participation on the Kuressaare Maritime Festival and the Kolm Põrsakest in the near future.
A Transparent and Participatory Process
The EIA program underwent a one-month public consultation period from January 16 to February 14, 2025, followed by a public hearing on February 27 in Lümanda, Saaremaa Parish. Input from local communities, government agencies, NGOs, and private citizens were carefully reviewed and incorporated into the final version of the program.
In accordance with § 18(1) of the Environmental Impact Assessment and Environmental Management System Act, this process ensured transparency, scientific rigor, and local engagement in the program’s development.
Key Adjustments Based on Community Feedback
The Tuul Energy team has made several important updates to the EIA program to reflect stakeholder input:
- Removal of Cable Route Alternatives C and D
Two of the four proposed cable route alternatives—C and D—have been removed. These routes would have connected the wind farm to the planned Estonian–Latvian marine interconnection. To avoid any potential conflict with this strategic infrastructure, these alternatives were excluded from further consideration. - Refinement of Remaining Cable Routes
For the two remaining cable route options, a buffer zone of 1,100 meters has been established. Environmental assessments will be conducted within these zones to ensure that the final cable alignment minimizes ecological impact. - Enhanced Underwater Noise Monitoring
In response to concerns about underwater noise—including low-frequency and infrasound—the EIA program has been updated to reflect the latest research from Estonian, Latvian & Lithuanian Environment OÜ. This includes methodologies for sound measurement, mitigation strategies, and a monitoring plan that will be implemented during construction and for six months afterward, particularly near residential areas.
A Milestone for Estonia’s Green Future
The approval of the EIA program marks a key milestone for Tuul Energy and for Estonia’s renewable energy ambitions. We remain committed to transparency, environmental responsibility, and close cooperation with all stakeholders as we move forward.
