R&D Facility | Iraklio, GRE 

SINN Power's location for 1:1 scale prototypes.

The scope of our research and development

Since 2015 we are testing and developing the SINN Power wave energy converter modules at the breakwater wall in Iraklio, Greece. 
Goal: To produce utilizable electricity to be fed into the grid.

Research project: To produce grid-compliant electricity with irregular waves

With its revolutionary approach to promote new green energy technology, SINN Power was able to receive a 

€ 1.0 million grant from the German Federal Ministry for Economic Affairs and Energy (BMWi) in 2017. With this grant, SINN Power is expanding its research activities on Crete with additional wave energy converter tests from 2017 - 2020. 


Five different wave energy converter modules will be installed at the breakwater wall in Heraklion, Greece. 

The goal of this research project is to test the electrical interconnection of several generators in SINN Power wave energy modules. The challenge is to translate the irregular oscillating motion of the waves into grid-compliant electrical current

After the final module prototype is installed in autumn 2019, SINN Power will build and test the first floating wave energy converter array with 21 modules with an overall capacity of 0.75 MW and approximately 1 km away from the coast. 

Wave climate

The coast of Crete located in the Mediterranean Sea has the best environment to test the durability and reliability of our technology within harsh environment.


Especially with heavy storms during the winter months and wave amplitudes up to 10 m at the breakwater wall, allows to test the SINN Power technology during harsh weather circumstances which is a crucial factor to avoid any damage for the customer. 

Why Iraklio?

SINN Power has experienced great support from the local authorities and governmental bodies with regards to legislative and executive tasks. Iraklio has a very good wave climate that allows maintenance and upgrades during the summer when waves are not too high.

WEC Development Stages

Setup R&D Facility Iraklio (2020)

SP WEC 3rd Gen - 06/2018

Floater diameter: 2.3 m

Installed PowerTrains: 6

Maximum Power: 18 kW

The 2nd generation WECs have been thoroughly tested and optimized since their installation in 2018

SP WEC 4th Gen - 09/2019

Floater diameter: 3.0 m

Installed PowerTrains: 12

Maximum Power: 36 kW

The 3rd generation of WECs have a significantly larger floater and more installed PowerTrains. This configuration is suitable for rough wave climates

SP Wind Turbine (3 kW) - 11/2019

Wing diameter: 4.5 m

Installed PowerTrains: 1

Maximum Power: 3 kW

SINN Power optimized a standard wind turbine by integrating the PowerTrain 3.4. It is mounted to the structure of the first WEC prototype

Ocean Hybrid Platform with Photovoltaic Modules (2021)


The agile and scalable development approach makes SINN Power one of the first developers worldwide who builds and tests power-generating systems in the sea. 

This is not only a R&D project, but also a fundamental step to lead the path of establishing wave energy and the SINN Power technology within the renewable energy mix.
