The WEC concept was originally developed at
Uppsala University, it was originally commercialised by the Swedish spin-out company Seabased Industry AB (SIAB). Early tests were conducted at the Islandsberg Test Site at
Lysekil on the west coast of Sweden, about north of
Gothenburg. The water depth at the site is about , located at . A total of 12 WECs were tested between March 2006 and August 2009.
Sotenäs, Sweden An array of 36 Seabased WECs totalling 1 MW and a subsea substation was installed off the coast of
Kungshamn,
Sotenäs in June 2014, at about 50 m water depth. The project was started in November 2011 and there were plans to deploy a further 9 MW at the site, however the project ended by 2018 as funding ran out. The generators are still in-situ as an artificial reef.
Ada Foah Energy Project, Ghana Seabased and TC's Energy are developing a wave farm in the
Gulf of Guinea, about off the coast of
Ada Foah in
Ghana. In 2014, a
power purchase agreement was signed to provide 1,000 MW of electricity to the
Electricity Company of Ghana. The first phase of the project was in installed in 2015 with the onshore switchgear connecting the first phase of wave energy converters to the local grid. However, the project stalled. In 2020, plans were announced to revive the project, with finance from
Power China covering 85% of the project cost, the remaining 15% bourne by TC's Energy Ghana. == Future plans ==
