Finnish ice-proof wind farm to be expanded
Hyötytuuli Oy is exploring the possibility of launching an expansion
project for the Tahkoluoto
offshore wind farm in Pori, Finland.
Ten SWT-4.0-130 turbines on gravity-based foundations were installed at
project in 2017. The wind farm is the world’s first commercial project
designed for icy conditions.
According to the developer, the expansion
in the preliminary study phase and its environmental impact assessment
(EIA) procedure is now well underway.
Suomen Hyotytuuli submitted the initial "EIA programme" to the
liaison authority, the ELY Center for Southwest Finland, in late April,
and a public consultation will run until 29th May.
The first EIA programme documentation includes:
- Basic information about
the project, its options and technical description
- A schedule for the
project and the EIA procedure, as well as a plan for organizing participation
- A description of the
current status of the project and review areas, a plan of which mpacts
will be assessed and the methods used to carry out the assessments.
Due to the COVID-19 pandemic, there will be no information and discussion
events on the EIA programme. Information about the project and the environmental
impact assessment is compiled on the company website. In addition, it is
possible for the project manager to ask questions and views by phone, email
and website form. An information and discussion event open to the public
will be held after the completion of the environmental impact assessment
The results of the consultation will feed into the creation of an EIA report
during the second stage of the EIA procedure. The environmental impact
evaluation will be carried out during spring, summer and autumn 2020. The
EIA report will then be submitted to the liaison authority in the winter
of 2020 and a decision on the EIA approval is expected spring/summer 2021.
Two possibilities are currently under consideration for the expansion,
including up to 40 or 45 turbines of 11-16 MW with maximum tip heights
of 300m, hub heights of 175m and rotor diameter of 250m. The wind farms
will be connected to the existing electricity grid in Tahkoluoto with the
potential addition of a new offshore substation. According to the tentative
schedule, construction of the wind farm could begin in 2023 at the earliest
with generation from 2025.
