Sotenäs is a
wave farm located in
Kungshamn
Kungshamn (''King's Landing'') is a locality and the seat of Sotenäs Municipality in Västra Götaland County, Sweden with 3071 citizens (in 2011). , in the municipality of
Sotenäs,
Sweden
Sweden, formally the Kingdom of Sweden, is a Nordic countries, Nordic country located on the Scandinavian Peninsula in Northern Europe. It borders Norway to the west and north, and Finland to the east. At , Sweden is the largest Nordic count ...
. The facility consists of 36 wave energy converters (WECs), with a total installed capacity of nearly 1
MW. Each WEC generates power using
point absorber buoys connected to
linear generators on the seabed. The generators are located at a depth of .
According to Seabased, the technology used in the project could deliver electricity for under 10 cents per kWh.
Initial announcements stated that the power plant would eventually expand to around 10 MW capacity,
but in 2017 Seabased announced it would no longer expand the plant beyond the 36 WECs already in place.
The Sotenäs wave park was not in operation between 2016-2020, with no buoys connected to the gravity-based PTOs. The site remains inactive, and is studied as an example of an artificial reef.
History
* In February 2010, the
Swedish Energy Agency awarded an investment grant to
Fortum

and
Seabased for the wave power station.
*9 December 2011, Fortum and Seabased sign an agreement to jointly construct a wave power station in Sotenäs, Sweden. Seabased agreed to manufacture buoys, generators, substations and converters at a factory to be built in
Lysekil
Lysekil () is a Urban areas in Sweden, locality and the seat of Lysekil Municipality in Västra Götaland County, Sweden. It had about 7,600 inhabitants in 2018. Situated on the south tip of Stångenäs peninsula at the mouth of Gullmarn fjord, it ...
. Fortum announced the power station would produce 10 MW by 2015, using 420 buoys.
* 13 December 2015, the test site consisting of four wave energy converters (WEC) was connected to the
Nordic grid in
Kungshamn
Kungshamn (''King's Landing'') is a locality and the seat of Sotenäs Municipality in Västra Götaland County, Sweden with 3071 citizens (in 2011). , through a low voltage marine substation and a long subsea cable.
* 14 January 2016, the four buoys were connected to the WEC, and thus generating electric power for the first time. An additional 32 WECs were eventually installed.
*In October 2017, Seabased announced it would no longer expand the Sotenäs power plant as originally planned. At the time of the announcement, the site was not actively generating power, but Seabased planned to continue to use it for research and testing purposes.
*In late 2017, Fortum transferred ownership of the power station to Seabased. Seabased announced it would use the site for testing and technology demonstration.
