Dassiesridge BESS Basic Assessment

Dassiesridge Wind Power (Pty) Ltd. is proposing the construction of a Battery Energy Storage System (BESS). The Dassiesridge BESS is proposed within the authorised Dassiesridge Wind Energy Facility (WEF) project site on the Grassridge Farm 187 near Uitenhage in the Nelson Mandela Bay Municipality (NMBM), Eastern Cape Province.

  • The proposed Dassiesridge BESS will cover an area of a maximum of four hectares (4 ha), contained within the eleven hectares (11 ha) study area. The exact location of the 4 ha Dassiesridge BESS, within the 11 ha study area, has been informed by the specialist studies.
  • The BESS will comprise of the following:
    • Up to 115 containers (each up to 40 m2), each with a capacity of up to 5 megawatt hours (MWh) and on a concrete platform. These will house the batteries, management system and auxiliaries.
    • Up to 60 transformer stations (up to 35 m2 each); 
    • Up to an additional 10 m2 per container for cooling units;
    • Internal access roads up to 8 m wide between rows of containers (Existing roads will be used as far as possible. However, where required, internal access roads will be constructed);  
    • Medium voltage cabling between containers and the switching station of up to 33 kilovolts (kV); and
    • 33 kV powerlines to connect the facility to the electrical grid (approximately 1 km). 
  • Temporary infrastructure including a site camp and a laydown area of approximately 0.3 ha.
