A 15kWp off-grid, ground-mount solar PV system was installed on a wooden sub-structure on Dassen Island.
The installation stores energy into a 48kWh Li-ion battery set and is integrated with a generator set as back-up.
The island is located 9km off Yzerforntein, Western Cape.
Since 2015 BVi has been involved in the design of five wind energy facilities throughout South Africa. One such facility near De Aar has been successfully completed, currently providing 100.5 MW of electricity to South Africa’s power grid, while two others (Perdekraal and Kangnas) are currently in construction with the remaining two (Excelsior and Golden Valley) scheduled to start construction in early 2019.
Combined, the five wind energy facilities will produce a total of 519.8 MW of electricity to the power grid of South Africa, relieving pressure currently put on our natural resources, such as coal, used to produce electricity.
Each wind energy facility has been designed to fit its local conditions.
Technical specifications at Perdekraal:
Turbine Model: Siemens SWT-2.346-108
Turbine Capacity: 2.3MW
Hub Height: 115m
Number of Turbines: 55
Foundation Diameter: 18.5m
Total Road Length: 30km
The BSG Warehouse, with an area of 20 000m², is located in Centurion, Gauteng.
It is equipped with 1115 light fittings of which 248 are LED highbay fittings.
Installation of a 367 kWp grid-tied rooftop Solar PV system, consisting of 1129 PV panels and 15 x SMA inverters
Where there is a road, there is BVi Roads and Rail - even to the middle of the country, at a wind energy facility (WEF) in De Aar.
BVi is assisting the client, Murray & Roberts Infrastructure, with the planning and geometric design of the internal road network, which serves as access from the major roads to the 67 newly constructed wind turbines. Technical assistance is also provided with the foundation design.
Engineering Design, Project and Construction Management for the Construction of a new 5MVA 66/11kV Distribution Substation for Nababeep, Springbok
Upgrading of Eskom's Karoo Substation for the Square Kilometre Array (SKA SA) Project near Carnarvon in the Northern Cape. This Substation's capacity was increased from 10 MVA to 20 MVA with a transformer redundancy of N+1 to accommodate the expected loads of the KAT7 and MeerKAT Phases of the SKA SA project.
This project also included a 33kV line specifically designed to have low RFI interference, an underground MV cable feeder and LV distribution network to each antenna at the Core Site. The total cost amounts to ±R65million and was completed in 2012.
