Could you imagine how p1ssed you'll be after 6 years of load shedding!

And no, the fat cats wont be fired, and yes they'll get their BIG bonuses.

No mention of our neighbours that enjoy cheaper power without the load shedding.

No mention of employing competent staff without colour considerations/restrictions.

Blowing smoke!


Power cuts are here for the next six years. But what's being done to solve the problem?

Power cuts will be a fact of life for the next six years, but here's what's being done to solve the problem.


This month, the national power conservation programme, a collaborative effort to counter our power shortage, comes into force. It draws on World Bank research that worked when Brazil had a similar energy crisis in 2001.

So what’s the plan?
The programme aims to reduce overall demand for electricity by 10–15% by means of:
# Sector-specific quotas. Proposed savings targets are 5% (agriculture); 10% (industrial and residential) and 15% (large office buildings, government, municipal and electricity utility offices). Essential services like hospitals and security installations are excluded.

# The quotas, still to be finalised, will be implemented in tandem with penalties for those who over-use.

# Incentives will encourage smaller users to exceed their savings targets.

# There will be a system of trading unused quotas (where larger users can ‘trade’ unused portions of their quotas with each other).

Okay, but what are Eskom and the government doing?
Eskom is investing a whopping R300 billion on new power plants over the next five years and, in his budget speech, trevor manuel set aside another R60 billion. They’re also tasked with sourcing more and better quality coal; older plants are to be ‘de-mothballed’ (although additional capacity will only be available from 2012), and discussions have intensified over the site of a second nuclear plant.

How does this affect me?
Well, firstly, electricity costs will rise by about 14,2% (excluding the new electricity levy) from 1 April, and some economists expect them to rise every year from now on. Then there’ll be a nationwide roll-out of compact fluorescent lamps (CLF’s), backed up by a restriction on the production of incandescent light bulbs.

CLF’s are more expensive, but you can expect to make back your investment in about 10 months. There will be a 20–30% subsidy, through registered installation companies (a full list is available on www.eskom.co.za), on the installation of solar water heating. Once it’s installed (priced between R7 000 and R20 000), your hot water comes free of charge. The DTI has also requested that the hospitality industry convert all water heating to solar power.

Smart metering for residential customers will allow Eskom or the municipality to switch off power in localised areas where the load is too high – to encourage the use of geysers, washing machines, tumble dryers, pool pumps and other appliances during off-peak times only. Also, government encourages fuel switching from electricity to LP gas as a domestic energy source.

What about poor households?
These will be supplied with free energy-efficient bulbs until 2015 (the South African National Defence force has pledged to assist by escorting the teams replacing the bulbs), and the solar heating roll-out will be free for them, too.

And cleaner energy?
The crisis "can also be seen as an opportunity to shift to a more long-term sustainable approach", says Earthlife Africa. They suggest tax deductions for those who implement energy-efficient measures, a fast-tracked training programme in efficient energy in all relevant sectors, and negotiations between energy-intensive users and renewable energy providers for localized power stations that will provide solar, wave and wind power. Another suggestion is for Eskom to pay feed-in tariffs (fits) to producers of renewable energy to capture and re-route it. But industry has yet to get excited about it: according to the Mail & Guardian, players in the renewable energy industry have accused Eskom of offering electricity at half the cost that they do.

Still, the DPE has since reaffirmed its commitment to renewable energy projects, and plans are in place to install solar-powered cells to power traffic lights and public lighting.

Can see a new joke starting - how many soldiers does it take to change a light bulb?

We can't use them to fight crime but they are pretty good at holding a ladder. Nuts.

Sounds like a good plan to me.

At least we come out of it more energy effiecient. Pity it had to be forced on us, but the outcome will be good for us.

To take things to the extreme...

Forcefully sterilising all children for the next 30 years, and mass culling of human beings would also leave us better off. Not such a hot idea though.

Now, while that is an absurd "analogy", it does highlight that the ends do not always justify the means.

Ummm, clearly you're so closed minded that you haven't noticed this thing called 'THE ENERGY CRISIS' that's happening in the rest of the world.

The fact that we sit on huge piles of coal in this country has made us so complacent as to believe that it would never affect us.

Well, guess what, it's arrived, it affects us, and it's a good thing that we're finally being forced into doing something about it.

OK - first off - drop the tone. I was not attacking you, and berating me for my "closed mindedness" is not constructive to the debate.

Yes, there is energy problems - however, this is not a good thing. Had we built clean power options years ago we would not be in this mess now. So, lack of planning on "their" part can not be justified by claiming any potential saving of pollutants etc. There are such things as wave power, solar power, nuclear power (let's not argue that here) and so on.

It arrived 10-odd years ago and those in the know deliberately chose to do nothing about it. The plan then was to have HIV/AIDS kill off the poor so that those remaining would have enough power. The plan then was to pretend that there wasn't a crisis in Zim and hope that all the Zimbabweans would stay there and not load our infrastructure. The plan then was to buy arms we didn't need and hope that the offsets translated into more electricity.

Sorry, you have lost me, at least how does the current situation fit in with the world energy crisis (in capitals) I though mismanagement, and AA where the guys that brought about this problem?

It fits in with the current world energy crisis by making us part of it, even if it has been caused by other peoples bad planning.

We've happily burning up our piles of coal, turning us all into least efficient, most polluting energy consumers in the world.

In this case, the cause was bad planning, and I'm not thanking Eskom for their incompetence. But at least it forces us to become more efficient.

If it's weren't for Eskom's incompetence we wouldn't now be forced to clean up our polluting, inefficient ways.

The cause more than justifies the outcome for me.

Nothing quite like using vast quantities of diesel in generators to fix pollution problems.

Exactly! Not sure where I read it, but it was something like a 50 sq km's solar array in the Karoo could supply all our electricity.

No coal, no diesel, no nuclear, just free sunshine.

It's nice that you can at least try to make a silk purse out of a sows ear. But we're not using less, we using all they can generate. And we're having to bring even older, dirtier stations back online. We're not being forced to become cleaner, we're forced to be dirtier.

Had the idjits done their jobs we'd have new technology power stations online already - and the assumption there is that they'd be cleaner.

In the short term, Yes. In the long term, No!

Again, we've had the crisis forced on us, and we're in crisis mode now.

But referring to the long term plan in the first post.

Punishing the ineffienct users. Incentives to save. All good plans with postives outcomes. I'd rather have this now than have had Eskom decide to build another 5 coal fired power stations 10 years ago which would now be pumping out even more pollution.

Deenem, I tell you what you can be extra environmental and save my 10% for me. Thanks, I need the power you obviously don't

In the long term we will run out of coal and oil.

All that means is that the definition of long and short term is subjective.

The crisis existed some 10-odd years ago. We (Joe Public) are finding out about the crisis now. 10 years ago the idjits could ahve started a campaign to educate people about conserving electricity, they could have changed the light bulbs then, they could have switched off government lights at night. But they didn't. They committed a fraud against the people of South Africa - they lied by omission.

And as I said - 5 new coal burning power stations are relatively more environmentally friendly than the ones they are taking out of mothballs. Hell, they could have built more nuclear power stations.

That 50 sq km's would give roughly 275 GW per day +- 50 GW peak (solar irradiance) if one could convert/store the energy at 100% efficiency

Using current PV's you would need to spend R 400,000,000,000 to cover the area (excluding wiring and trackers) and at about 19% efficiency would only get out 9.5 GWe (Peak). One large (current) powerstation is good for about 4 GWe...

If one used Solar thermal generation, you could cut costs and improve efficiency depending on the method use (eff between 20% and 40%). However it would still not be enough power for the country.
