Sigma Energy was established in 2008. Its sole purpose is the development and commercialisation of the patented Sigma WEC technology. The company has already designed, built, and tested several scaled models as well as a 1:5 scaled device tested in the Adriatic Sea. In 2019, Sigma Energy was awarded cofunding from the ERDF and the Republic of Slovenia to develop, deploy and test the full-scale Sigma WEC device for the Adriatic Sea. Deployment is planned for July 2022.
