LOCAL SITE VISIT 1

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.

We will then continue to Ankerlig Open Cycle Gas Turbine (OCTG) Power Station located within the industrial area of Atlantis, near Cape Town. Open cycle gas turbines can be fuelled by either natural gas or liquid fuel (kerosene or diesel). The hot, high velocity gas used to turn the turbines is exhausted into the atmosphere. The open cycle gas turbines are relatively environmentally friendly as they have higher efficiency and burn a cleaner fuel (diesel) than Eskom’s coal-fired power station fleet. 

Delegates will learn more about the benefits of using OCTG technology including: 

1. How the technology has been used extensively all over the world and is readily available 

2. How stations can be erected in a lead time of 2 – 3 years as opposed to the larger coal and nuclear stations that require 8 – 10 years lead time 

3. The proven track record of this type of technology

LOCAL SITE VISIT 2

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 grey water 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.

BOOKINGS FOR THIS SITE VISIT CLOSE ON FRIDAY 14 APRIL AND ENTRY WILL BE BASED ON STRICT SECURITY CHECKS

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. This site visit will end with lunch at a wine farm. 

 

LOCAL SITE VISIT 4

Our first stop will be to Hotel Verde, which is the only hotel in the world to be LEED (Leadership in Energy and Environmental) Platinum certified for their design and construction, as well as their operation. A grey water recycling system saves an average of 6000l a day, making sure drinking water is never flushed and rain water is collected in a 40 000l stainless steel tank in the basement, which feeds their drip irrigation system.

The hotel also has 220 Photovoltaic panels, three wind turbines (vertical axis), regenerative drive elevators, energy generating gym equipment and an energy-saving heating and cooling system coupled to ground source heat pumps. They have a 6 star rating from the Green Building Council of South Africa.

After lunch on a wine farm we will proceed to the historic Lourensford vineyard in Somerset West, which is also home to Sustainable Power Solutions ( SPS ) head office and test site. Lourensford was one of the first commercial farms in South Africa to invest in renewable energy. The initial project saw SPS  install a 500kWp solar photovoltaic (PV) plant on the roof of the winery which generates an average of 2000kWh daily, enough to run the winery and feed surplus energy to the internal grid supplying the rest of the estate. In addition to helping the historic estate manage future energy costs, the PV plant reduces carbon emissions by an estimated 720 tonnes per year. 

Following the success of the initial project, SPS in collaboration with Mettle Solar Investments has installed a 95kWh commercial Tesla Power pack System  in an off-grid configuration. The Tesla Power pack System will initially be used to store excess energy produced by the rooftop PV plant, allowing the office to run almost entirely on renewable energy. At a later stage, the Tesla Power pack will form an integral part of a microgrid test facility, which will be used to pre-configure microgrids before being implemented at remote locations.

LOCAL SITE VISIT 5

We will first visit Black River Park which was the first renewable energy project to feed back into the grid and incorporates solar on all viable roof spaces, performance glass and LED lighting in all common areas.  The building is operating 53% more efficiently in energy and 58% with water than the market average.  They have a 1.2 MW photovoltaic solar plant, on-site waste sorting and recycling and on-going storm water quality inspections and management.

After lunch in the Paarl Winelands delegates will visit the Cape Brewing Company which 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.

LOCAL SITE VISIT 6

From May 2017 Robben Island will move toward a renewable energy system, as part of the Department of Tourism’s transformation (Tourism Incentive Programme) efforts. The system designed and installed by SOLA Future Energy, will assist the island in migrating from its reliance on fossil-fuelled diesel generators, by installing a 666.4 kWp Ground Mounted Solar Photovoltaic (PV) System, with a 500kW, 837.32 kWh Battery to form a pure micro grid and thereby ensuring reliable, clean power to the island.

As part of the DoT’s Tourism Incentive Programme, converting Robben Island to solar power is estimated to save the island over R 6M per year in diesel costs and is expected to reduce the CO2 emissions of the island by 860 Tons per annum. The annual energy consumption of the island is over 2 million kWh, with a peak load of over 400 kW.

In addition tour delegates will also get to visit all the historical sites around the Island. The tour guides inside the prison are former political prisoners and are fully conversant and knowledgeable about the Island’s multi-layered 500 year old history. The tour route includes the graveyard of people who died from leprosy, the Lime Quarry, Robert Sobukwe’s house, the Bluestone quarry, the army and navy bunkers and the Maximum Security Prison where thousands of South Africa’s freedom fighters were incarcerated for years. The tour culminates with a viewing of Nelson Mandela’s cell.

After lunch delegates will visit the new Netcare Christiaan Barnard Memorial Hospital building has been designed to international safety standards and incorporates sophisticated green principles and technology to ensure on-going sustainability. Considerable emphasis has been placed on the inclusion of design elements to optimise infection prevention and control and enhance patient wellbeing and their hospital experience.

The Netcare hospital is currently being powered by the Xiria E Medium Voltage Switchgear by Eaton, Xiria E is the name of Eaton's new medium voltage switchgear for smart grid applications. The system is characterised by its high level of operational safety and suitable for applications up to 24 kV. The Xiria E switchgear is designed around Eaton's proven vacuum interrupters, which require no maintenance and are certified for 30,000 operation cycles. The Xiria E is Safe in Use with visible isolation by means of inspection windows in the front and Logical mechanical and electrical interlocks prevent formal operation. Other key features include being environmental friendly, reliable and safe in operation, low total cost of ownership and user friendly.
