Clean Energy for a Million Households

The Poseidon offshore wind farm is part of a larger push to have 100% renewable electricity production by 2040 in Sweden.

The Poseidon offshore wind farm is part of a larger push to have 100% renewable electricity production by 2040 in Sweden.

  4. Poseidon Offshore Wind Farm

Vattenfall and Zephyr, two Nordic leaders in renewable energy, are planning an offshore wind farm on the west coast of Sweden, in the southern Skagerrak/northern Kattegat region about 40 km northwest of Gothenburg.

They are applying for a permit for the Poseidon offshore wind farm. According to estimates, the proposed wind farm will have a maximum of 94 turbines with floating foundations, possibly the first in Sweden. The project will generate approximately 5.5 TWh of electricity per year, or nearly 4% of Sweden's electricity consumption, supplying about 1 million households.

As part of the permitting process, WSP is responsible for preparing the environmental impact assessment and supporting studies for the establishment of the wind farm under Sweden’s Economic Zone Act (SEZ) and the internal cable network under the Continental Shelf Act (KSL) as well as supporting the client during all stages of the permitting processes.

Our assignment includes providing strategic support to Zephyr and Vattenfall. WSP will continue to support the client in the next phases of the project.

Achieved milestones

In December 2022, an application for a wind farm permit under the SEZ and KSL Acts was submitted to the Swedish government. WSP was responsible for preparing the environmental impact assessment for both application processes and is continuing to give strategic support to the client during all stages of the permitting process.

Bat Surveys and Solutions for the Mining Industry

Bats are an integral part of our ecosystems, and some bat species in Canada are currently listed as endangered due to population declines. In order to receive provincial or federal environmental authorizations, surveys to assess impacts on Species at Risk are critical for many projects. Compensation measures for bats may also be required and solutions to enhance or protect bat habitats can be integrated into restoration or mine reclamation sites.
