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
The solar water heating rebates introduced in 2008 ended in April 2015 and whether they will return is a matter of debate within both the industry and among consumers. SESSA doesn’t know whether the rebate programme will be reinstated and if so, what form it will take.
However, the conditions for solar water heating have shifted markedly over the last 7 years with the steep increase in electricity tariffs making the notion of ‘going solar’ increasingly attractive.
Even without the rebate, it still makes sense to switch to solar water heating
Projected savings through solar water heating show that over the next 5 years and assuming a modest annual tariff increase of 8.5%, one will achieve, in Rand terms, as big a saving or indeed even more as you would have if you had invested in a solar water heating system at any time during which the rebate was available.
*SESSA Solar Water Heating Chair, James Green, takes us through the numbers.
(*Sustainable Energy Society Southern Africa)
Let’s look at a few facts as to why and how solar water heating should now be approached.
The cost of electricity has gone up by 100% since 2008, and energy efficiency is now more relevant than ever before. Over the next 5 years it is likely that the kWh price will increase by another 50% or more.
There are some 2,400 electricity tariffs in SA. A price per kWh of R1,85 is chosen for 2015-16, but will be higher in areas such as Cape Town
Choosing a Solar Water Heater – The Research Steps
Choosing a solar water heater is quite daunting. It sounds like a great idea, but do you know what you are actually going to get? Unfortunately it is not as simple as comparing an LED bulb with a 6 Watt rating, giving the same light output (measured in lumens) as a 60 Watt incandescent bulb. Here you can easily work out that you are saving 44 Watts per hour for the same energy service.
When it comes to solar water heating, you need to have some understanding of how much electricity you are using in heating water by electricity. Then you can determine which solar water heater is going to meet your energy savings needs and which represents the best value for money.
A couple of simple, basic facts will make it easier:
For every 36 litres of hot water out of a shower at 40 °C the temperature most of us feel comfortable showering at, you will use 1 kWh of electricity (This is calculated using formulas that take the specific heat capacity of water and average municipal cold water temperatures into account).
Most showers use 16-20 litres per minute, so a 5 minute shower will use between 90 and 100 litres of hot water at 40°C.
Dividing 90 litres by 36 litres gives you 2.5 kWh and at 100 litres, 2.77 kWh.
With 4 people in the home all showering for 5 minutes once a day, the energy used amounts to 10kWh at 16 litres per minute or 11.11 kWh at 20 litres per minute.
Using an average kWh cost including VAT of R1,85 in 2015, that accounts for an amount on the electricity bill of R564 to R627 per month respectively.
However, it all depends on lifestyle…
Hot water use monitoring shows that hot water use at 40 °C ranges from 130 litres per person per day to as high as 220 litres per person per day, depending on seasons, regional variations and lifestyle.
To put that in perspective, for a 4 person home and at a tariff of R1.85 per kWh, usage at 130 litres of hot water per person per day accounts for an amount of R815 per month and at 220 litres per day R1 378 per month.
How much hot water do you use in your home?
A simple exercise is to add up all the minutes your family members spend in the shower in a 24-hour period. We suggest you do 3 different sample days and average the result. Then multiply the minutes by 16 litres for conservative hot water use or 20 litres for generous hot water use. Take the total and divide by 36 to get the kWh consumption.
The graph below gives you a quick illustration
Value for Money – Which System You are Considering
Having chosen the output of the SWH in deemed kWh savings per day you can also do an easy analysis of value for money. 2 simple exercises are:
Take the deemed kWh output per day, and multiply that by your cost per kWh from Eskom or your municipality. That gives you a Rand figure per day for savings. Divide that into the installed cost of the solar water heating system, to get the payback point or break-even point in days on your investment.
Calculate your savings over a number of years. Take the daily Rand savings on the system for Year 1 (multiply by 365), and add it to Year 2 having increased the savings by inflation (8% is a conservative figure), and repeat over future years.
Rebates – Not the Reason to go Solar
So finally back to the question of rebates. Does it still make sense to go solar without rebates. The answer is a resounding YES!
To illustrate this is:
If you had bought a 150l SWH in 2008 with an output of 7,5kWh per day you would have saved approx. R22,000 over 5 years including the rebate.
If you had bought the same system in 2014 it would save you R33,400 over 5 years including the rebate.
If you bought the same system today without the rebate it would save you R30,000 over 5 years.
So even without the rebate it makes total sense to go solar and indeed every year the price of electricity goes up it makes even more sense.

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:
Extract from the media release:
Going forward a new rebate scheme will be introduced and subsidies will be offered with considerations regarding local content.

“This should inject a jolt of momentum in the lead up to a global climate agreement in Paris.” (Andrew Steer, the CEO of World Resources Institute)
With an agreement between China and US, more nations will feel comfortable climbing aboard.

U.S. and China Reach Climate Accord After Months of Talks
BEIJING — China and the United States made common cause on Wednesday against the threat of climate change, staking out an ambitious joint plan to curb carbon emissions as a way to spur nations around the world to make their own cuts in greenhouse gases.
The landmark agreement, jointly announced here by President Obama and President Xi Jinping, includes new targets for carbon emissions reductions by the United States and a first-ever commitment by China to stop its emissions from growing by 2030.
Administration officials said the agreement, which was worked out quietly between the United States and China over nine months and included a letter from Mr. Obama to Mr. Xi proposing a joint approach, could galvanize efforts to negotiate a new global climate agreement by 2015.
It was the signature achievement of an unexpectedly productive two days of meetings between the leaders. Mr. Obama and Mr. Xi also agreed to a military accord designed to avert clashes between Chinese and American planes and warships in the tense waters off the Chinese coast, as well as an understanding to cut tariffs for technology products.
A climate deal between China and the United States, the world’s No. 1 and No. 2 carbon polluters, is viewed as essential to concluding a new global accord. Unless Beijing and Washington can resolve their differences, climate experts say, few other countries will agree to mandatory cuts in emissions, and any meaningful worldwide pact will be likely to founder.
“The United States and China have often been seen as antagonists,” said a senior official, speaking in advance of Mr. Obama’s remarks. “We hope that this announcement can usher in a new day in which China and the U.S. can act much more as partners.”
As part of the agreement, Mr. Obama announced that the United States would emit 26 percent to 28 percent less carbon in 2025 than it did in 2005. That is double the pace of reduction it targeted for the period from 2005 to 2020.
China’s pledge to reach peak carbon emissions by 2030, if not sooner, is even more remarkable. To reach that goal, Mr. Xi pledged that so-called clean energy sources, like solar power and windmills, would account for 20 percent of China’s total energy production by 2030.
Administration officials acknowledged that Mr. Obama could face opposition to his plans from a Republican-controlled Congress. While the agreement with China needs no congressional ratification, lawmakers could try to roll back Mr. Obama’s initiatives, undermining the United States’ ability to meet the new reduction targets.
Still, Mr. Obama’s visit, which came days after a setback in the midterm elections, allowed him to reclaim some of the momentum he lost at home. As the campaign was turning against the Democrats last month, Mr. Obama quietly dispatched John Podesta, a senior adviser who oversees climate policy, to Beijing to try to finalize a deal.
For all the talk of collaboration, the United States and China also displayed why they are still fierce rivals for global economic primacy, promoting competing free-trade blocs for the Asian region even as they reached climate and security deals.
The maneuvering came during a conference of Pacific Rim economies held in Beijing that has showcased China’s growing dominance in Asia, but also the determination of the United States, riding a resurgent economy, to reclaim its historical role as a Pacific power.
Adding to the historic nature of the visit, Mr. Obama and Mr. Xi were scheduled to give a joint news conference on Wednesday that will include questions from reporters — a rare concession by the Chinese leader to a visiting American president.
On Tuesday evening, Mr. Xi invited Mr. Obama to dinner at his official residence, telling his guest he hoped they had laid the foundation for a collaborative relationship — or, as he more metaphorically put it, “A pool begins with many drops of water.”
Greeting Mr. Obama at the gate of the walled leadership compound next to the Forbidden City, Mr. Xi squired him across a brightly lighted stone bridge and into the residence. Mr. Obama told the Chinese president that he wanted to take the relationship “to a new level.”
“When the U.S. and China are able to work together effectively,” he added, “the whole world benefits.”

I first visited Lithos Wine Farm during last year’s Helderberg wine festival and was so impressed with their hospitality, beautiful views and their award winning wines. I simply had to purchase some of their wine and we keep it for special occasions – and life really offers so many special occasions!!
You will notice the solar water heating panels on the roof which we installed for them during October 2014. The solar geysers are hidden inside the roof and the benefit of solar geysers is that they are well insulated against temperature loss. Both of these installed systems qualify for the Eskom rebate.
These solar accessories on roofs are excellent indications of a home owner’s commitment towards using more environmentally friendly ways to heat their geyser water. Most of South Africa’s electricity is produced by burning coal, which has a major environmental and health impact.
Kindly contact Lithos Wine Farm at Tel: 021 858 1851 or email@example.com to book a wine tasting, so that they know to expect you. Wine tasting can be arranged during the week from 9am to 4pm sildenafil 100mg price.

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.
The cold water from your swimming pool is pumped through the solar pool heating panels which are installed on the roof of your house (on the north facing side of the roof). The heated water from the panels is redirected through a closing valve back into the existing piping leading back to your pool. The water is circulated for the whole time while the pump is running. Your existing pool pump is used, therefore no additional cost is incurred.
You want to have your solar pool heating panels installed on the roof of a double storey house…. please note!
We recommend a 1,1 kWh pool pump for best results. This is not to say that the 0,75 kWh pump will not work but rather that the solar system efficiency will be reduced by using a 0.75 kWh pump.
How many panels do you need for solar pool heating?
Measure the length and width of your pool. For example (4 meters x 8 meters = 32 meters) divided by 3.6 will indicate that you would need a north facing area for 9 panels of 1.2 meters in width and 3 meters in length.
If your pool pump is faulty and needs to be replaced?
Hint: Keep in mind that the higher the watts, the more electricity your pump will use. A 0.75kW pump is sufficient for most swimming pools (for both the pool cleaning/filtering and circulating the water through the solar heating panels). If you are unsure, you are welcome to give us a call.
We also offer heat pumps for swimming pool heating:
We also offer heat pumps as a solution where the solar pool heating won’t suffice (where a much higher temperature is required during winter months).
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!!
