Sunly’s SW4 Offshore Wind Farm is planned with 11 wind turbines with a total capacity of 132 MW. The building area of ​​each wind turbine is 500 m2, thus a total area of 5,500 m2. 
The foundations of the offshore wind turbines are located on the seabed with a depth of 9-22 meters. The choice of the foundation design depends on the type of the wind turbine chosen and the location of the wind turbines in the wind farm, as well as the conditions identified during the environmental impact assessment studies.
The total area of the wind farm is 17,8 km2.

The offshore wind farm is planned to be connected to the main grid either in Paldiski or Aulepa. The exact details of the grid connection are yet to be designed.
