Site visits


Sterrekus substation

Delegates will visit the Eskom Sterrekus substation, commissioned in 2015, and is the final substation in the 1600km 765kV corridor that provides an increase in transfer capacity between Mpumalanga in the north and the Western Cape in the south, of approximately 4,000 MVA. 

The station design includes a 765kV bus-bar reactor that can be reconfigured to act as a line reactor under certain contingencies. The 400kV yard make use of live tank switchgear technology and is also configured in a breaker and a half substation layout. Operating in the substation is done through HMI technology and the protection schemes are based on IEC 61850 communication protocol.

Genius of Space

The Biomimicry Genius of Space project is wastewater treatment system designed to find an innovative solution to water pollution in the Berg River. Delegates will get to see the completed aspects of the project including the greywater disposal points and filtration systems in between houses in the pilot area. In addition the tour will cover the other green infrastructure for grey water filtration such as a micro wetland and tree gardens and find out about the different challenges of working in the informal settlement and the other aspects of the project that are still to be built in later phases.

Koeberg Nuclear Power StationBookings for this site visit close on Friday 14 April

Nuclear energy currently provides approximately 11% of the world’s electricity and through Koeberg Nuclear Power Station near Cape Town it powers most of the Western Region and supplies approximately 4.4% of South Africa’s total electricity needs. 

On this exclusive site visit delegates will get to see the Emergency Core Cooling System, the Turbine hall, CRF/SEC pump house and the low level waste.



Lourensford Wine Estate

A visit to this beautiful wine estate located in Somerset West will showcase their solar PV plant which generates electricity during sunshine hours and feeds this into the grid and is used throughout the Wine Estate. At night the plant goes into stand-by mode.

The solar PV plant operates completely autonomously and requires no intervention by the owner. The plant requires minimal maintenance, and the solar modules are cleaned six times a year to ensure optimal production. These solar modules will still be generating more than 90% of their original nameplate capacity (250Wp) at date of purchase after 20 years.

Cape Brewing Company

Cape Brewing Company has invested in solar power technology to power its production line enabling them to produce South Africa’s first commercially available “green beer” which uses solar heated water in the brewing process. The solar power system includes 12 m² × 10 m² solar thermal collectors, which transfer heat to a 10,000 litre water storage container through a heat-exchange station.

The project objective was to reduce the brewery’s paraffin fuel costs by a minimum of 50%, while at the same time reducing the manufacturer’s carbon footprint and production costs. This is the first time that the Austrian produced solar thermal panels have been used in Southern Africa.

The Bokpoort CSP plant – Northern Cape (overnight site visit)

Opened in March 2016 this plant is the first in Africa equipped with molten salt tanks that provide thermal storage capacity of 9.3 hours. This means that Bokpoort can continue to produce electricity long after the sun has set. In its first month of commercial operation, the plant produced electricity continuously for 161 hours, or more than six days, setting a new record for this technology in Africa.

The plant was built by a joint venture of Spanish companies ACCIONA, SENER and TSK and South Africa’s Crowie. It was developed for ACWA Power, the Saudi group, as an EPC (Engineering, Procurement and Construction) project and required an investment of more than 300 million de euros.

The project is a pioneering facility in the renewables sector for the South African industry, in addition to making an important contribution to the social and economic development of local communities.

Delegates will fly to Upington, Northern Cape on Friday 19 May and return to Johannesburg or Cape Town on Saturday 20 May.
