Ever wondered what going solar is really all about? We answer your questions below… Transcript from Pick n Pay

We chat to Richard Jamieson, managing director of Yes Solar, one of South Africa’s leading solar energy companies, to find out all the answers to our solar questions.
1.  Why is solar power better than regular electricity?
Bottom line, you’re using a source of power that is 100% renewable. You’re not ‘using up’ the sun by putting a panel on your roof. Next most important thing is that it’s clean. Sure, the panel requires energy and materials to make, but after that you don’t produce any greenhouse gasses or other waste products when using solar.

2.  Isn’t it very expensive to install?

The upfront cost is high, but the real number to look at is your payback period. This is how long it takes for your savings to add up to the upfront cost. Solar water heating systems, if correctly sized, pay for themselves in 3 to 4 years. This is much less than it used to be, thanks to higher electricity prices and to the Eskom rebate.

3.  Is it true that Eskom offers a rebate?

Eskom has something called a Demand Side Management programme, and one of the initiatives of that programme is to offer a rebate to people who buy solar water heaters. The rebate is a cash amount which is paid out within eight weeks of installation. The process is managed by Deloitte. Rebates can be anywhere between R3000 and R13000, depending on the size and efficiency of your system.

4.  Isn’t solar power only for hippies?
This might have been true in the past, but these days solar power is for people who want to save themselves money, and for people who want to be less dependent on Eskom, and for people who want to reduce their own carbon footprint. If you rely on Eskom in SA your carbon footprint is big, because they’re so reliant on coal to produce the electricity we all use.

5.  How much money could potentially be saved by going solar?

This depends on a number of factors – mainly how many people in your home use hot water and what their water usage habits are. Somewhere between R200 and R400 a month for 2-5 people living together with fairly normal water usage habits.

6.  What if it’s cloudy all month and there’s no sun?

Every system we install has electrical backup. A timer/controller on the unit makes sure that hot water when you need it by activating the element (if solar alone is not getting the water hot enough).

7.  How reliable is it?
Reliability is a key factor when making a purchasing decision. You’re buying something that should last you twenty years, so choose carefully and don’t go for the cheapest option. Choosing a company that is going to provide good backup service is also important. Look for a supplier that has SABS mark approval.

8.  How does one go about getting it installed?
Call us and we will come round and do a site visit which will allow us to put together a solution (or range of solutions) that suit your home and your budget. If you decide to go ahead, installation takes roughly one day per geyser.

The draft twenty-year plan for electricity generation, also called the Integrated Resource Plan (IRP) 2010, was released a few weeks ago for public comment. The IRP process is all but a fait accompli. But what goes into the plan will determine the future of South Africa’s energy mix for the next two decades.
The energy choices available to us are between coal, nuclear, gas, hydro and other renewables.
With a projected GDP growth rate of 4.6% over the next 20 years, South Africa will need new capacity of about 52,000 megawatts (MW). Renewables will constitute 16% of the new technology mix to provide required electricity demand, while nuclear energy will provide 14% and coal 48%.
Why is an IRP important?
Well, energy or electricity is like blood running through the veins of an economy. Without it, our fledgling modern state would collapse. Never mind the myriad other things that are stalled without electricity, but crucially, without it, we would be unable to expand the economy and attract new investments, which in turn could limit the scope of job expansion.
The IRP process also tells us about how we think about energy-economy linkages, how we think of energy in relation to environmental and social justice issues, projections of future demand and how we use every unit of energy. At the heart of it, too, is the appropriateness of the energy mix.
Some are casting a close eye on the proportion of power generation that will come from coal, nuclear and renewables. There are lots of views about what should be included and excluded.
It at once also sums up the normative transitions we have made from the past to the present when thinking about energy. At once, all the country’s vices and virtues are nestling their way into the IRP process itself.
The IRP, which is so crucial to South Africa’s economic future, is a process run by a few experts within the state and some major users like mining companies. It is observed by ‘outsiders’ such as policy wonks, industry lobbyists, energy experts in policy think tanks, universities and civil society activists.
But in the end, it literally amounts to a few people making profound decisions on behalf of the majority.
Hearings on the IRP 2010 will be held sometime – in different provinces – at the end of November running into early December. The interest in the new plan from consumers, civic groups, business, unions, financiers and international investors is overwhelming.
You are, after-all, talking about throwing another large chunk of new taxpayers money beyond the current infrastructure projects already earmarked by the state at a new set of infrastructure projects.
How does the IRP process work?
The plan lays the basis for Eskom to submit an application to the National Electricity Regulator (NERSA) to permit it to go ahead with the financing of new power projects or the purchase of power from private generators.
In other-words, NERSA approves a tariff that would accommodate the cost of building the new power infrastructure. The tariff seeks to reflect the true cost of electricity generation. Once a tariff has been approved these costs can be recouped from consumers. Eskom can then go and raise additional funds to build the power stations it needs or procure power from private generators of electricity.
The current plan, while still in an initial state, has some good, but also worrying things about it.
The first positive thing is that we have actually have embarked on a planning process for electricity. It is the first time that this is being done in South Africa and this in itself sets a good precedent. It is a process we can learn from and build on in the future.
The second good aspect of the plan is a tacit admission that coal’s future looks slim. The share of coal as a major source of electricity generation for the future is declining.
The main reason, despite the claim that we have 200 years of coal (which is proving to be untrue given recent coal estimates), is that any new sources of coal have an inherent insecurity in them because of question marks about the quality of the coal and the unpredictability of the future price. This situation is worsened by the fact that we may not have the infrastructure in place in time to dig out enough coal from the ground to supply demanding and hungry coal-fired power stations.
Eskom and SASOL have at least acknowledged that coal, as a generous energy feedstock, is constrained. Thus, the golden days for coal are over.
The third good thing about the IRP is that this is the first plan to be literally operating with a carbon budget in mind. Some may argue it does not go far enough. But the fact that ‘reducing our carbon emissions’ is chosen as a parameter for consideration, is a major conceptual breakthrough for energy planning and electricity generation in South Africa. It has never been done like this before.
However, as much as it is convenient to have a carbon budget approach and ratchet up the numbers on renewables to support a low carbon path, it also serves as a justification and a way to sneak in nuclear energy as a low carbon solution. No doubt there will be furious debate on the inclusion of nuclear.
The diminishing prominence of coal-fired power also has other reasons attached to it. Any new financing, at least from the Western World that has carbon reduction as a goal, will not be easily forthcoming for coal plants. Soft finance will be more readily available for renewables and to some extent for nuclear.
The fourth positive aspect relates to drawing power from other sources in the Southern African region – mostly in the form of small and some large hydropower opportunities. South Africa’s demand for power could stimulate more investment in hydro projects in the region. The amount of hydropower that will be drawn will be close to 3,300MW. This is almost equivalent to one coal-fired power station.
As other countries in the region become more stable this share of power from the region can increase.
But there are also weaknesses in the plan. The plan still adopts the “old school” way of thinking about electricity, which is etched through its fabric of scenarios and assumptions. In this way, it is very supply side orientated.
Thus, while the IRP takes a ‘least cost’ approach for supply solutions, it does not do so for demand management.
Compared to a lot of modern economies South Africa does not score too well on energy efficiency and the new electricity plan is quite meek in its ambitions for energy efficiency.
We need an economy in which participants use less for more and in which economic planners shift to sectors that are diversified away from energy intensive industries towards low energy sectors that produce higher economic value.
Yet the IRP covers very little about how we can reduce South Africa’s energy intensity, especially, with respect to collective behavioural change and a unified vision for a new type of economy.
The plan seems to exude deep scepticism about our ability to shift behaviour and relies on engineering solutions rather than a values approach that can alter future demand patterns for the consumption of electricity.
The fact that there are interesting numbers in the plan for different types of technologies does not mean it will be executable. The new build – as it is sometimes described – will require R800bn of additional funding. The cost of electricity will rise from 40c/kWh to about R1.10/kWh. This is a 275% cost rise for electricity generation within the next ten years.
This has profound implications for how much of the plan’s vision can be achieved.
In the meantime, existing plans to build two new coal-fired power stations will go ahead. A portion of renewables like wind energy could be slotted in expediently because we are desperate for quick wins in the next five years to avoid load shedding.
The call on a fleet of nuclear power stations is still to be made. It is not as yet a done deal. Too much spend on nuclear may well squeeze out a higher generation target for renewables – what economist call the “crowding out” effect.
What is executable will also be encumbered by the governing realities of our politics and economy. Without a radical solution, the status quo remains in place and some vested interests will continue to prevail.
The IRP 2010 will no doubt be a plan that will be intensely fought over because undergirding it all will be a contest to assert different visions for our energy future and economy.
However, despite the IRP 2010 being seeped in technocratic language, it is, after all, a plan about our future that must be driven by what values we posit for that future. Getting there in unified way is no small task. Either we build consensus organically or the state manufactures consensus.

Green energy project george
George Municipality could be the first municipality in South Africa to buy privately generated electricity. The news was revealed at a site inspection on 25 October 2010 of the R200-million green energy to electricity project, between the state owned Central Energy Fund (CEF), Carbon & Environmental Options (C&EO) and other stakeholders.
In the Picture – Ms Busi Mabuza – CEF Group Chairperson, Karel Siegel, MBH Executive; Dr Phindile Masangane – Project Manager CEF and Mr Mputumi Damane – CEF Group CEO with some of the equipment for the proposed green energy to electricity project.
According to CEF project manager Dr Phindile Masangane, the plant will produce a maximum of 8.8 megawatts  electricity (MWe) and could export a maximum of 7.5 MWe into George’s electricity grid by 2012. This would provide George with about 10 percent of its electricity requirements.
George Municipality will not be making a capital investment in the plant as it will be funded by CEF and its partners.
George Executive Deputy Mayor Lionel Esau, councillors and the electro-technical department paid a visit to the site with Dr Masangane,  CEF chairman Busi Mabuza, chief executive Mputumi Damane and MBH Energy executive Karl Siegal to inspect equipment that has been imported from India.
MBH Energy will build the air-cooled power island that will convert the green waste to electricity.
The plant requires 110 000 tonnes of green waste, such as forest and sawmill waste, woodchips, bark and sawdust to generate the required electricity per annum.  Siegel said the waste would be burnt in a boiler which would generate 4 000 tons of steam that would then turn the turbine that powers the alternator to produce the  electricity.
Masangane said that 75% of the main equipment is already on site, which stands on the former Sonae Novabord property in George Industria.
Construction of the plant could start in August 2011 and if plans go according to schedule, the plant could be commissioned within nine months.

solar park

Fluor has announced that it was selected to perform a study for a potential solar park development in the Northern Cape for South Africa’s Department of Energy.

Following the recent completion of a pre-feasibility study by the Clinton Climate Initiative, a program of the William J. Clinton Foundation, Fluor will now develop a more detailed conceptual master plan to be unveiled at the upcoming South African Solar Park Investors Conference Oct. 28 and 29 in Upington, Northern Cape Province of South Africa. Fluor will book the undisclosed contract value in the fourth quarter of 2010.

“We are closely collaborating with South Africa’s Department of Energy and the Clinton Climate Initiative on this potential flagship solar power development,” said Dave Dunning, president of Fluor’s Power Group.

“Our company has a strong track record of achievement in South Africa. Just last month, Fluor commemorated its 50-year anniversary of ongoing capital project development in South Africa, and we hope to bring this clean energy initiative to fruition.”

The 5 gigawatt solar park is one of the largest proposed solar parks in the world. Upon completion of the conceptual study, a more detailed design plan will be developed.

The South Africa Department of Energy intends to establish a Solar Park Authority as a unit within the state-owned Central Energy Fund to facilitate the advancement of the project.

The solar park could host proven and emerging solar technologies including photovoltaic (PV), concentrated photovoltaic (CPV) plants and concentrating solar power (CSP) technologies such as power tower and parabolic trough alternatives.

When fully developed, the 5 gigawatt solar park could realize a total investment of more than US$20 billion according to the Department of Energy.

Fluor is a global leader in the engineering, procurement, construction, maintenance and operations of the world’s most challenging and complex power generation facilities.

It is currently building the world’s largest offshore wind farm off the coast of the United Kingdom, and its completed power projects have been recently recognized as top projects by POWER Magazine, Platts and Power Engineering.

Households that invest in solar water heating can get a subsidy of up to 40% from Eskom on equipment.

GEORGE BUSINESS NEWS – A new report released by the department of energy warns that power failures are once again on the agenda unless drastic measures are implemented.
What exactly these measures entail, remains unclear.
But by being pro-active, you can ensure that your own household is at least always assured of the comfort of hot water.
Only a few years ago you really had to search for a company to install a solar water heating system, but today prospective clients can pick and choose between 500 suppliers countrywide.

Get the right supplier
But, has this made it any easier? In quantity maybe, but pick your supplier very carefully.
The key to a system that will suit your household needs perfectly, lies in determining your exact needs. The system should provide in your hot water needs, save you money and minimise your carbon footprint. As electricity prices escalate, the National Energy Regulator of South Africa (Nersa) approved the introduction of preferential rates for those who invest in solutions for reduced energy consumption.

Households that invest in solar water heating can get a subsidy of up to 40% from Eskom on equipment, and will also be able to reduce energy costs through the preferential rate on offer.
The residential inclining block tariff has four different rates with lower consumption blocks offering lower rates.
But regardless of these special tariffs to Eskom clients, a solar heating system will save everybody 70% of their monthly water heating bill.
That is, if you have the right system.

How to get the rebate
Vincent Davis, technical director of Green Power Solar Systems says many myths surround the issue of Eskom rebates. “Countrywide about 5500 households have received rebates after installing solar heating systems. It was implemented about two years ago to reduce the residential load. It needs to come down by about 10%. In 15 years’ time we will need double our current capacity.”

But the energy provider’s long-term inability to cater for our needs is not the only reason not to delay installing a solar system.
The Eskom subsidy is expected to decrease over the next four years and a 40% saving is not to be sneered at.
However, Davis says Eskom is very strict and will only pay out the subsidy if you abide by its rules.

“The size of the rebate depends on the performance of the system ie how much units you save Eskom, the system that you install, and then it must also be supplied and installed by an Eskom accredited supplier. The system must also be SABS approved.” A list of approved suppliers can be found at www.eskomdsm.co.za.

Davis says people should also look at the guarantee and warranty and whether it is SABS approved or just SABS tested. “This could make a huge difference as the SABS mark of approval means that the whole manufacturing process has been inspected and ensures quality of product.”

Go green
A 150-litre heating system will spare the atmosphere 1,6 tons of CO² per year – the burning of 820kg coal.
New legislation will force all new homes of 300m² or more to fit solar geysers and other ener-gy saving products.
And the green benefit will also have a ‘green buck’ spin-off.
The resale value of green pro-perties shows a dramatic increase as people are increa-singly in tune with eco friendly investments. According to Davis, Green Power is into solutions, not the selling of products.
“Every home and family pose unique challenges and to get the most out of your solar heating system in all respects, all factors should be considered and brought together to ensure the perfect solution for you.”

Wind turbines china

The world’s top polluter, China, is a surprise leader in clean energy efforts, a study showed Tuesday, outstripping the United States and Japan and leaving Australia lagging far behind.

The Vivid Economics report, commissioned by Australia’s Climate Institute thinktank, showed China was second only to Britain in the value of its incentives to cut pollution from electricity generation.

Britain’s efforts were estimated at 29.30 US dollars per tonne of carbon to China’s 14.20 US dollars, with the United States clocking 5.10, Japan 3.10, Australia 1.70 and just 70 US cents for South Korea.

The six countries account for just under half of all global emissions.

“The Chinese leadership have made a strategic decision that they missed out on the last two industrial revolutions and they don’t want to miss out on the third one,” said Erwin Jackson, director of the Climate Institute, of China’s “surprising” dominance.

“They are now commanding the largest market share of clean energy investment at a global level as a result,” Jackson told AFP.

China’s investment in clean energy topped 35 billion US dollars in 2009 compared with 11 billion in Britain and 18 billion in the United States, and Jackson said it was set to increase tenfold over the next decade.

The main driver of China’s performance was its commitment to shutting down more than 100 small coal-fired power plants for cleaner coal stations by 2011, which the report said would reduce emissions by 15 percent.

It also offered subsidies worth billions of yuan for green energy projects, aiming to generate 15 percent of the nation’s total energy from renewable sources by 2020.

In Japan, 10 major power producers had joined a voluntary scheme aiming to cut emissions by 20 percent of 1990 levels by 2012, a major initiative which accounted for more than half of its clean energy rating.

Variations of an emissions cap-and-trade system were in place in South Korea, Britain, Tokyo, and parts of the United States, the report said.

The study said there were few policies which applied directly to coal, despite the fact it was the major source of fuel and carbon pollution for the six countries.

It also warned that none of the countries was on track to meet reduction targets agreed after last year’s global climate summit at Copenhagen, with Japan lagging worst in relative terms.

Jackson said the report showed that Europe and China were ahead of the game on pollution reduction investment, far outpacing countries such as Australia — the world’s worst per capita polluter due to its heavy dependence on coal.

Without action to price carbon, he said Australia risked falling foul of anti-pollution taxes, with countries such as Japan and India already taxing imports of coal and similar moves foreshadowed in the United States and Europe.

Australian Climate Change Minister Greg Combet welcomed the report, saying a carbon price “will not only provide an incentive to reduce pollution but also … drive this country’s long-term competitiveness”.

The ruling Labor party in Australia, the world’s largest coal exporter, has shelved emissions trading laws after failing to pass them and nearly lost power at August polls, with the eco-minded Greens party winning a record vote share.

Prime Minister Julia Gillard, now at the head of a Greens-backed coalition government, has urged penalties for carbon pollution and formed a cross-party committee to investigate the best way to slash emissions.

offshore wind farm

disclaimer: image is for illustration purposes only

Google has agreed to invest, along with other partners, in a massive offshore wind power project along the U.S. Mid-Atlantic region.

The Atlantic Wind Connection “backbone” deep-water cable transmission project, led by Trans-Elect, is expected to provide approximately 6,000 megawatts of offshore wind capacity, enough power to serve 1.9 million households, when fully complete.

Other investors include Good Energies, a global investor in renewable energy, and Japan’s Marubeni Corp.

Instead of requiring multiple connections, the transmission line will serve as a “superhighway with on-ramps for wind farms,” said Rick Needham, director of green business operations at Google, the Philadelphia Inquirer reports. It will link to land at four locations: North Jersey, South Jersey near Atlantic City, the coast of Delaware and the coast of Virginia south of Norfolk.

The transmission line would run about 15 to 20 miles offshore. That’s up to 17 miles further out than the controversial Cape Wind project off the coast of Massachusetts, which has encountered fierce local opposition on aesthetic and environmental grounds.

AWC developers say that the turbines — with 295-foot hubs and 197-foot blade lengths — would barely be visible from beaches and residences, National Geographic News reports.

The system could also be expanded to accommodate additional offshore wind energy as the industry further develops.

AWC would involve high-voltage direct current instead of the high-voltage alternating current typical of most wind farms. Trans-Elect says HVDC cables are cheaper, have lower energy loss and use less copper than HVAC cables.

“The AWC backbone will both relieve transmission congestion in one of the nation’s most restricted power markets as well as enable the development of a huge offshore wind capacity that can bring stability and security to the Eastern Power Grid,” John Breckenridge, managing director at Good Energies, said in a news release.

Construction of the project is expected to begin in 2013, after the necessary permits are obtained and completion of an environmental review process.

“This can dramatically accelerate development of renewable energy,” Needham said. “This is in line with our commitment to a clean energy future, where we believe that being good environmental stewards makes good business sense.”

In May, Google made its first direct investment in clean energy, when it bought a $38.8 million stake in two North Dakota wind farms.

Pointing out that AWC is still in its early stages, Needham said “we’re willing to take calculated risks on large-scale projects that can move an industry.”

Google is to provide 37.5 percent of the equity for the initial development. While none of the investors would provide dollar amounts, The New York Times reported that Google’s initial investment in the project would be $200 million.

solar park

The department quoted Energy Minister Dipuo Peters as saying: “A woefully wrong impression is being created that presupposes that, in view of the fact that the current draft IRP2010 only makes provision for the target of 600 megawatts by 2017, then it follows that the Northern Cape Solar Park will not happen as it falls outside of the IRP. This is not the case.

“Realistic targets for electricity generation can only be included in the IRP once we have completed the feasibility studies which will provide certainty with regard to, amongst others, the necessary core data with regard to the time frames for the implementation of the envisaged solar park, the scale of its operations, the mix of solar technologies that will be used to generate electricity using the sun rays as well as mechanisms that are needed to secure integration into the national grid,” she said.

The department was committed to initiating large-scale solar projects in order to contribute to the security of energy supply.

It was in this respect that the prefeasibility study that was conducted by the Clinton Climate Initiative confirmed that 5 GW of cost effective electricity generation was achievable through the deployment of solar projects.

The draft IRP was written with enough flexibility to accommodate the Solar Park concept, the statement continued.

The Solar Park provided “the real arsenal” to deploy technology that could replace the fossil-fired power generation.

Peters reiterated government’s commitment that 30 percent of new generation capacity would be produced by independent power producers.

The development of a large scale solar park would be a significant part of this once government had the benefit of reviewing the current draft that is out for public comment.

Renewable energy technology in South Africa is ready and waiting; it just has to be rolled out.

This was the conclusion reached by the panellists at the second of the Shell Energy Dialogues last Thursday.

The discussion was chaired by CNBC Africa presenter Lerato Mbele and included Wendy Poulton from Eskom; Richard Worthington from the World Wide Fund; Professor Johann Görgens from the University of Stellenbosch; Stuart Fredman from Clean Energy Solutions; and Barry Bredenkamp from the Central Energy Fund. The theme of the evening was “Alternative Energy: Pipeline or Pipedream?”

South Africa has pledged itself to the target of 4% renewable energy by 2013, but the question is whether the country will be able to achieve this goal, given the monopolisation of coal-based power producer Eskom in the local energy market.

“The only way we’re going to achieve a just transition to a sustainable electricity supply is to maximise the role of renewable energy,” said Worthington. “The future will be predominantly and eventually entirely in renewable energy.”

But, warned Bredenkamp, the responsibility for the transformation to renewable energy is not solely the government’s responsibility: “You and me as individuals also have a role to play. There’s a lot of alternative energy that we can use in our own homes.”

South Africa has massive renewable energy potential, with its many hours of sunshine and wind. Developers are keen to get started, but the problem is getting it to the people.

“Who is the developer going to sell [energy] to? You have to be able to transmit it across the national grid,” said Fredman. “Give us access to the national grid and we’ll achieve the energy targets and bring the levelised cost of energy down over the next 10 years.”

Cost issues
Part of the problem of getting people and industry to use alternative energy is the cost.

Fredman explained: “The cost is slightly higher over the short term than [coal-fired power stations] … but as we look over 10, 15, 20 years, the cost comes down to be level with coal, and then significantly lower.”

A factor in renewable energy’s favour has been the recent global economic crisis and the rising costs of oil and other energy.

Görgens said: “The renewable energy debate in the last five years has really picked up momentum because of global economic changes. Economics will always play a very strong role.”

People must look at the long-term benefits instead of the initial cost, added Worthington. “A compact fluorescent lamp will save you a lot of money over its life cycle.

“Don’t look at the cent-for-cent comparison per kilowatt hour for alternative energy as opposed to coal; rather look at the cost of not having energy. What is it going to cost the economy if we don’t do something quickly and run out of coal-fired power?”

Fredman proposed a solution: “We pay two cents an hour for some form of carbon tax and it’s been sitting in the Treasury … At the moment it has a quantum value of about R8-billion. So the money is there to start a reasonably large roll-out of renewables.”

It is important for South Africa to start implementing renewable energy technology as soon as possible, said Bredenkamp. “South Africa is one component of a large globe … Most countries are accelerating their update of alternative energy. These technologies have to be manufactured and the longer we wait, the further behind we get in the queue.”

“We have a very energy-intensive economy,” said Poulton. “We not only have to change our carbon systems, we also need to look at the energy beyond our economy and become more energy efficient.”

Johannesburg – An alternative source of energy from Sasol will provide thousands of homeowners with a significantly smaller monthly energy account, as well as a smaller carbon footprint.

On Tuesday the petrochemical giant introduced its new Sasol Homegas product at the Waterfall Country Estate in Midrand, currently the largest property development in the country and the first to use the gas.

The product is liquefied petroleum gas (LPG), which is stored in large 6 200-litre to 22 500-litre gas tanks on the premises of the development for use as an alternative energy source.

It is the first such project and Sasol plans to roll it out on a large scale countrywide in new developments.

It’s a step in the direction of a greener future, said Pieter Claassen, Sasol Oil’s manager for new business development.

It is especially targeted at developers of new housing and at the low-income housing market.

He said the gas would be used to heat water, for indoor heating and for cooking.

At the same time the houses will be supplied with solar panels.

This would reduce the average household’s dependence on electricity by about 60%. The saving on the total electricity account would be 18% to 20% and households’ carbon footprint would come down 40% to 50%.

It would considerably reduce the pressure on South Africa’s electricity network and ensure that buildings had a reliable alternative source of energy at all times, lightening the household burden of rising electricity tariffs.

This gas is already being used in millions of homes globally, but its use in South Africa has always been limited because the country until recently had cheap electricity.

The infrastructure to install the product will add to developer’s costs.

Claassen said a R1.5m house would cost an average of 1% more to build and low-income houses about 2% more.

Mark Corbett, chief executive of Century Property Developments which is developing Waterfall, said the gas will be stored on the premises and distributed to each house.

Each house will have its own gas meter and households will be able to pay for the gas in advance.

Waterfall is currently the biggest residential development in the country and 3 000 houses will be built there over the next five years.

Corbett said the stands sell for between R600 000 and R6.5m for units from 600m² to one hectare. The first three stages, a total of 700 erven, have already been sold.

Sasol Homegas will be installed by qualified staff in compliance with all international and domestic safety standards.

The gas has a distinct smell, so that any leaks can be picked up and traced immediately.
