After two and half years of intensive development, Sigma energija d.o.o. (Sigma Energy) is proud to announce that we have successfully deployed our full-scale Sigma WEC prototype offshore Bar in Montenegro. The 30-kW device was deployed in mid-July and shows extremely promising results.
The deployment is the result of Sigma Energy’s successful application to the public call »Dopolnjevanje SME Instrumenta – Faza 2« (Supplement to SME Instrument – Phase 2) for co-funding the project of developing the Sigma WEC full-scale device.
The investment is co-financed by the Republic of Slovenia and the European Union from the European Regional Development Fund.
We will update the site with further details on the development and deployment of our Sigma WEC prototype shortly so be sure to return.
Sigma WEC – deployment and testing
The company Sigma energija d.o.o. (Sigma energY) has successfully applied to the public call »Dopolnjevanje SME Instrumenta – Faza 2« (Supplement to SME Instrument – Phase 2) for co-funding the project of developing a Sigma WEC full-scale device.
In November 2018, the European Marine Energy Centre (EMEC), one of the leading technical authorities on the utilisation of wave energy, visited our site in Montenegro where they witnessed the scaled Sigma WEC. EMEC performed a detailed inspection of Sigma Energy’s methodology for power performance and officially verified it.
WE ARE MAKING
We have successfully deployed a scaled device in the Adriatic Sea. It was feeding electrical energy into Montenegrin power grid for 6 months and has already withstood extreme conditions.
More than 80 parameters such as device motions, wave, mechanical and electrical parameters are being monitored in Sigma Energy Monitoring Centre.
A WORD FROM THE OWNER AND INVENTOR
Welcome to the world of sustainable and clean energy. We are all aware that nurturing our planet and securing healthy living for ourselves and our descendants is the future. By researching, developing and implementing devices that produce clean and ecological energy I believe I am giving my contribution to this effort.
Over the course of 15 years I have worked on converting ocean wave energy into electrical energy. My team and I have reached respectable technological level that was confirmed both in the laboratory and at the sea. At Sigma Energy we proved unprecedented efficiency level by converting 45% of the available wave energy into electricity at the tank tests in France at the renowned Ifremer facilities in Brest. Our theoretical framework proves that the efficiency can be further increased significantly, which means this already impressive result is only a beginning. By defining clear priorities and intensifying research and development towards yet greater efficiency and lower capital and maintenance costs we increased overall system reliability. Behind all of the greatest achievements, there is never a single person but rather a team. I am using this opportunity to thank my professional team for all the hard work put in this project.
Our “KNOW HOW” is the one that will make a revolution in green energy.
On this website, you may find an overview of the company and our technology. We are at your disposal regarding further development of our project and its patent commercialization. If there is a joint interest in our project, you are most welcome to contact us.

LATEST PROTOTYPE TESTING
In December 2017, Sigma energy successfully deployed its largest scaled device off the coast of Montenegro. The device sets a precedent for Sigma WEC technology as well as the wave energy sector. The video below shows the deployment of the device which further strengthens Sigma Energy’s position among marine renewables.
SIGMA ENERGY was established in 2008 in order to develop and deploy the wave energy converting technology, covered by several international patents filed by the company owner and lead engineer, Mile Dragić PhD. The company has been able to support the ongoing development process including design, construction and deployment of several scaled models.
Some of the development steps were supported by local and EU funds (Marinet/FP7), but majority of the financing was assured by the company owner. After successful proof of concept phase and several optimization trials the owner has secured the funds for the next phase (full scale device deployment) and we are currently in the process of choosing the deployment destination.
We have been actively building an international partnership network and are cooperating with several test zones and key supply chain members from wider UK area, Ireland, Denmark, Norway, France, and Portugal. With the full scale device in the pipeline (deployment date depends on location and large scaled testing and is currently set for 2018/2019) we are in search of strategic partners from countries with ocean coastline that would aid further, commercial deployment.
WAVE ENERGY RESOURCE
Wave power varies considerably in different parts of the world. Areas of the world with abundant wave power resource include the western coasts of Scotland, Ireland, Portugal and Norway in Europe, northern Canada, southern Africa, Australia, and the northwestern coast of the United States, particularly Alaska.
