The utility has confirmed the power stations have less than three weeks of supply left and some even have less than 10 days in their reserves.
Spokesperson Khulu Phasiwe says: “We don’t want to mislead people and create unnecessary panic. At the time, we also don’t want to create a sense of comfort. All we can say is that the risk of load shedding is always there, but we’re managing it.”
An electrical geyser can contribute between 40% and 60% towards your monthly electricity bill, depending on your household’s hot water consumption. We at Solar Juice can retrofit your existing electrical geyser with solar and enable you to help lower the pressure on Eskom’s coal crisis. Many households use only the sun to heat their geyser water from October to March (depending on the weather).
Converting your electrical geyser to solar is definitely contributing towards lowering our country’s carbon footprint one solar geyser at a time and it releases the pressure on the much needed coal resources during this time of crisis.
Solar Juice would love to help you make the best of the sun’s amazing energy. Our service delivery area: Western Cape (Helderberg, Boland, Cape Town, Overberg, Winelands, Breede Valley, Swartland).

Predictions: Unaffordable increases in future electricity tariffs
The massive cost overruns on Eskom’s new power stations mean huge and unaffordable increases in future electricity tariffs, says the Cape Chamber of Commerce and Industry.
“We are afraid there is no escape from the consequences of the quadrupling in the cost of the Ingula pump storage scheme and the doubling of the costs of the two coal-fired power stations, Medupi and Kusile,” says Janine Myburgh, President of the Chamber.
“To make matters even worse, the cost estimates do not take into account the huge amounts of interest which Eskom has to pay on loans during the construction period. This includes dollar loans which have to be repaid with weakening rands.”
The original cost estimate for Ingula was R8,9bn but this has now ballooned to R36bn. In April 2007 the cost of Medupi was estimated at R69,1bn but in July this year costs were, according to Eskom, R135bn while the cost of Kusile has increased from R80,6bn to R135bn.
“We learn two things from these figures,” says Myburgh.
“One is that electricity from the Medupi and Kusile will cost well over R1 a unit and that costs will continue to rise each year along with the costs of coal, transport and wages.”
“The second thing we learn is that massive cost overruns are normal for big projects and this will also apply to any nuclear build programme. There are many examples from around the world which confirm this.”
Myburgh says the recent study by the CSIR found that the cheapest “new build” option for additional electricity was a combination of wind, PV solar and gas.
“These three technologies are all ‘quick builds’ and their recent history shows projects are completed on time and on budget and they are not subject to the annual costs increases we see in coal-fired power stations,” says Myburgh.
Eskom had now decided that it did not want to buy any more electricity from independent power producers.
“What this means is that the private sector will increasingly turn to roof-top solar which can already compete with the retail price of electricity. Eskom will lose more customers and as the demand for grid electricity declines the case for nuclear power will fall apart.”

Comments from Solar Juice:
Solar energy vs coal
Households can lower their electricity consumption:
An electrical geyser contributes between 39% and 50% towards your home’s electrical bill. This translates to between R390 and R500 per R1000 of your electrical bill. The biggest saving for South Africa is when we use less electricity during the peak hours (high demand) and we also set the timers to work outside those peak hours.
You contribute towards a healthier South Africa!!
A big THANK YOU to all the households who have switched to solar water heating so far as well as for those in the process of doing so. To read more about the environmental contribution you make (one installation and 100 installations)….every switch from electricity to solar counts!! Click here
This article is about a *natural flow solar geyser system with a flat panel (as in the picture) which we serviced recently. The question is to: Service a solar geyser system…yes or no?
*natural flow = thermosiphon (it is where the geyser is located higher than the solar water panel and no pump is required to circulate the water between the geyser and the panel).
After a few years of working hard to harness the sun’s energy to heat your geyser water, various factors may play a role in the continued efficiency of your solar geyser system:
The environment and man may have an impact on the need for a service over time.
The sun/birds/squirrels may be working away at the *lagging around the water pipes on the roof; * lagging is insulation material which limits heat loss.
We sometimes find that squirrels and/or rats enter the roof space and damage the Geyserwise controller wires and or lagging within the roof;
Dust and other material may collect on the surface of the panel(s) and impact on the absorbtion of the sun’s heat energy;
Another factor may be that repairs to the municipal water network may result in debris moving into your solar water panels and impact its efficiency;
Just after the installation, the new owners are usually very excited to experment with the different options on the timer and over time they forget and then the settings don’t really suit their needs anymore due to changed circumstances in their household;
Maintenance work at the house may result in someone stepping on parts of the solar geyser pipework or other parts and damage occurs;
Smaller parts (element, timer, pressure control valve, etc.) may be or become faulty, although we stick to trusted parts from reliable suppliers.
We find that the service requirements differ from area to area due to the weather and environmental differences. We therefore propose a basic service for our existing clients in order to keep the expenses as low as possible. If we find that e.g. the lagging need to be replaced, we then first discuss it with the client and get his/her approval to replace it. The basic service has a fixed cost (if we have to travel quite a distance, we will then discuss additional fuel cost with the client beforehand).
This is a solar geyser system we installed almost 5 years ago.
DoE extended the rebate – Media release, dated 4 Feb 2015
Eskom notified the SWH (solar water heating) industry on 7 January 2015 that their rebate comes to an end on 31 January 2015 and would be handed over to the Department of Energy (DoE).
The DoE notified the SWH (solar water heating) industry via their media release, dated 4 Feb 2015, that the rebate is now extended by the Department of Energy (DoE) for another 5000 systems to be installed in South Africa with the same rebate amount per system as with the Eskom rebate programme. DoE will provide more information about their future rebate programme soon.
Extract from the DoE letter:
“With effect from 2 February 2015 the Department has availed subsidies (up to a cap of 5,000) buy sildenafil citrate 100mg. The number of subsidies is informed by past performance of the partial rebate programme under Eskom (about 2,000 monthly installations over the past nine months). No further subsidies will be available under this programme once this cap is exceeded.
1.2 The latest Eskom rebate levels, together with the payment services offered by Eskom (through Deloitte), will remain unchanged subject to (1.1) above”.
A new rebate scheme will be introduced by DoE soon:

Installing a solar geyser system for Fred’s tree services in Somerset West has been a highlight for us. We like to share our experiences when installing solar for other businesses and also to share information about the service provided by these businesses. The mutual interest is caring for the environment and taking the necessary steps towards a healthier environment.
Today, we share information about Fred’s tree services.
Fred Lewis (also known as Dr Tree) is no stranger to heights and shows his satisfaction after inspecting his newly installed solar water heating system with the Helderberg Mountain forming a beautiful background.
About Fred and Fred’s Tree Services:
Fred is well-known for his compassion and work with trees under his company name: Fred’s Tree Services. They specialise in the pruning, felling and chipping of trees. Fred is a member of the International Society of Arboriculture and boasts with German qualifications.
Fred has registered various trees as national monuments in order to save the beautiful trees from being cut down. That is a brilliant showcase of his commitment towards the environment and also with this step to move from a coal-based water heating solution to a solar based heating solution.
This solar water heating system is a natural flow (thermo siphon) system, where the geyser is located higher than the panel. The investment in a solar water heater (geyser) system is one of the best investments, since you save considerably on your monthly electricity bill and it reduces pollution. Electricity load shedding won’t bother Fred after a long day at work, he will be able to relax with a hot shower.

Solar Juice installs at Eskom Sere Wind Farm
We (Solar Juice) had the privilege to install 2 solar water heating systems on the building at Sere Wind farm, outside Koekenaap (near Vredendal) which is about 350km from Cape Town. (The Sere Wind Farm is Eksom’s first large-scale renewable energy project and this is the first major step in a drive to reduce SA’s heavy reliance on coal to generate electricity).
This was quite an exciting project to be involved in. The work safety measures are very strict and well communicated beforehand. It is great to see that the first 7 of the total 46 wind turbines came into action on 10 Oct. 2014. These 7 turbine generators produces close to 16MW power. This is enough to light up about 30,000 households. An excellent start for this project.
Solar Juice installs 2 solar geyser systems at Eskom Sere Wind Farm
Eskom lowers its carbon footprint with this project:
The 2 Solar Geyser systems will help Eskom by storing the sun’s energy in the geyser water (heat) for utilisation when required. A 200 liter electrical geyser would have resulted in the burning of at least a 1000kg of coal annually to generate electricity and would have resulted in 4.5 tonnes of harmful CO2 and other gasses to be released into the air every year. This way, and especially with the wind turbines, Eskom is lowering their carbon footprint in this amazing new project.
Sere Wind farm connects to national grid in South Africa
Posted by: ESI Africa October 17, 2014
The construction of the Sere wind farm reached new heights this week with the energising of the transformers of the first string of seven wind turbine generators, a move that paved the way for Eskom to commence with the final commissioning of these turbines.
“I am sure that the team will continue with the same drive and commitment until all 46 wind turbines are in operation,” said Eskom Chief Executive Officer, Tshediso Matona, chief executive officer of Eskom, South Africa’s utility.
Sere wind farm is Eskom’s first large-scale renewable energy project, and forms part of the utility’s commitment to renewable energy and reducing its carbon footprint.
Eskom’s senior general manager for renewables, Ayanda Nakedi, said: “Last Friday (10th October 2014) we synchronised the first seven wind turbines to the national grid, adding 4.4MW as part of the final testing and commissioning process. The achievement of this milestone is in line with our target date of December 2014 and we remain on track to be in full commercial operation by end March 2015”.
Once completed, the plant will add 100MW to the national grid and contribute to saving nearly 6-million tons of greenhouse gas emissions over the 20 years expected operating life, with average annual energy production of about 298 000MWh, enough to supply about 124 000 standard homes.
“Wind conditions have been favourable, and this past Monday, the Sere wind farm was contributing 15.7MW to the national grid,” said Nakedi
The R2.5-billion wind farm will also help diversify Eskom’s energy mix and contribute to South Africa’s objective of meeting 42% of the country’s power demand with renewable energy sources by 2030.
Matona expressed his appreciation for the work and progress achieved, “My thanks go out to the entire team for enabling us to reach this most significant of milestones. This milestone has been achieved through close co-ordination between various departments in Eskom and our contractors. This is evidence of what we can achieve as an organisation when we work together.”
Describing Sere Wind Farm
Sere Wind Farm is Eskom’s first full scale renewable energy project, situated on the Western Cape Province of South Africa, located north-west of Vredendal, approximately 350 km north of Cape Town. It sits on a 3 700 hectare plot of land in Skaapvlei near the town of Koekenaap Eskom’s Sere Wind Farm will comprise 46 Siemens 2.3-108 wind turbine generators. The project includes construction of a new substation and 44 km of 132 kV distribution line linking the new Skaapvlei substation to the existing Juno substation.
It is believed that the earth receives more energy each hour from the sun than the world can use in a full year. In spite of this, South Africa generates 77% or more of our electricity by burning millions of tonnes of coal each year …. imagine the pollution effect on our natural resources: air, water, soil and ……the resultant health effect!!
