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.
Sigma Energy was awarded a certificate – Seal of Excellence, by European Commission.
Sigma is preparing for the deployment of a 30 kW device that completely mimics the full scale device. It will be deployed off the coast of the Adriatic Sea, which is according to our experience with prototype testing a very good representation of ocean. At the same time Sigma is constructing a 3 MW full scale device for ocean which is planned to be deployed in 2021.
WE ARE MAKING
We have successfully deployed full scale device for Adriatic Sea. It has been feeding electrical energy into Montenegrin power grid for 6 months and has already withstood extreme conditions, operating in unusually high waves at the site corresponding to 27m of height at full scale, which no other WEC has done yet.
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 prototype off the coast of Montenegro. The full scale device for Adriatic Sea 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.
