We are all sick of load shedding... all these schedules to keep up with and being without power for 2.5 to 5 hours in a single day just sucks.
I can't imagine the loss for businesses.

So, how can this be fixed?
Well, let us first identify the main problem why "Load Shedding" does not work.

INCENTIVE.

Incentive to save power, to be more clear.
In the current load shedding system nobody gives a damn about actually saving power.
We're all in this system that cuts power on a predetermined schedule, depending on the load (Stage 1-3).
A person in Boksburg has no incentive to shut down some of his appliances if his schedule has already passed. The guy sitting in Durban is perhaps scheduled and therefore sitting without power.

So round and round we go... the ones inside the schedule sit with zero power, and the rest of the country off the schedule just use as much power as they want. Why? cause they don't care,
They aren't concerned about trying to save any power at all because they are not currently in load shedding. It's not their problem.

This is the flaw with the current load shedding system - nobody has any real incentive to try and save power.
"Why Turn off my TV's or lights, It's Witbanks turn to cut their power!"



So here's how it can be fixed.

In my system everyone will have power. all day. no scheduled power cutting. ;)

Let's call it "Load Balancing".
In this system, the country is divided into groups. perhaps every city can be a group, or maybe every municipality.
For the sake of the argument, let's split by cities. Also, please do not nitpick MW values, I'm just using simple figures as an example and to make this easy to understand.

Eskom allocates each city a "power budget" based on historical data. Let's say Boksburg needed 100MW in the past.
We now only might have 80% of the total power capability we had a few years ago before that power station went down, so Boksburg has 80MW.
Every city now has a figure. Boksburg has 80MW, Durban might have 120MW, etc, etc.

Everyone with me so far?

Each city gets an allotted MW value. There is no more load shedding schedules. Nobody needs to sit with no power for 2.5 - 5 hours based on some time table.
Now, If the people of boksburg don't want to save power like the rest of us, and they go over their 80MW limit, their power gets cut. BOOM.
The power will switch back on in 15 minutes. They now have a chance to switch off excess appliances, lights, geysers, TVs, etc, etc. in this 15 minutes.

If, in 15 minutes, they have not switched off enough, the power will go off again - This time for 30 minutes. C'mon boksburg, get your act together now.
30 minutes later and nobody in boksburg is working together to save power? Now it will only try to come on in 1 hour. Still not enough? Now it will only check every 2 hours.... until they switch off enough.

They are the only ones responsible for being without power.
This gives an incentive for the people of "Boksburg" to cut their electricity usage. If they can't cut their usage habits, only they are going to suffer... not everyone else.

Once people realize that if they don't work together, that only their own power will remain cut, I guarantee you people will start switching off appliances very quickly.

If George citizens manage their power well, they might never see any power cuts.
Twitter can be used, too. You subscribe to "Eskom_George" for example, and if George's power reaches 90% capacity, Eskom can sent out a tweet to that account. simple as that.
DSTV could have a channel with a map of south africa, color coded by power usage, and perhaps a list of the top 10 cities that might need to watch out.


This system makes it so that everyone has power - just a little less. If we can manage our power better, there will be no cuts.
Businesses won't lose as much money due to power cuts, or needing to use generators.... and we don't need to sit in the 18th century for 2 to 5 hours every day.

People will be encouraged to save power, because if they can't save electricity, only they themselves will sit without it.



Your thoughts?

The issue with your solution: you are punishing those who don't use as much power if they are grouped together with someone who uses a lot.
Also, most power is used by businesses (such as the aluminium smelters) and not home users.

I have a better idea, disconnect those not paying for it.

Smart meters allow this.

I don't want it to be up to some illegal connections in Mamelodi or some rich bastard in Waterkloof who have underfloor heating and what what and insist on using it, (and has a big generator, so loadshedding se gat).

Load balancing on the individual level I am 100% fine with.

My understanding of smart meters is that it does something similar to this, but on a more individual level.

At least the whole of South Africa isn't being punished with some random schedule, only the city that is mismanaging....

Yes some people who try to save might be grouped together with others, but at least there is some incentive for the rest to unplug.
Once that power goes, and people understand that if they do not start cutting before 15 minutes it will go off longer, they will definitely start unplugging shlt.

This could be worked in.

What we need is an open system where anyone can feed back into the system or do voluntary load shedding on demand for certain price. The latter is already a working system in Aus btw...

I pretty much stopped here, being generalized as such

In the current load shedding system nobody gives a damn about actually saving power.

Well it's true for the most part. Why would the guy in Durban care about switching off his appliances, when the people in PE are busy load shedding?
The people in PE are without power so the guy in Durban can use whatever he wants.

Does nobody understand incentive?
With the current system the people who are using up too much power don't get punished, it's some other people, somewhere else. So why would they care?

You're basically describing load limiting... CoJ is slowly implementing it, not on a 'boksburg' scale, but individual houses. So, those who reduce don't get shed, those who don't reduce, get shed. In theory you get an sms warning saying something like, 'we are shedding in 30min, you're using too much, drop 5%' or whatever. 30 minutes later, if you haven't reduced, you are cut for 30sec. Power then comes back on, it tests again, if you still haven't reduced, 30 sec again etc, after 5th time, if you haven't reduced, you get cut for 30min. Process then starts again, test, not co-operating, cut for 30min. The idea is if every household reduces load, everyone can still have electricity... but to be fully effective, need to roll out more smart meters

Foo cheque eishkom! As long as I have power I will do what I smaak.

As long as people have the above attitude, it will never work.

Idiots think they're spiting Eskom by wasting electricity. You're just hurting yourself at the end.

of course the only real solution here is to actually get rid of the cause: anc

My understanding is they are/have implemented it in the whole of Aspen Hills.

I have a laptop, hard drive and big data bundle which hold me through load shedding every time.

Otherwise I'm never home and never notice it... thankfully.

Yes it seems I have come up with something that already exists (only on a per-household basis not by city) :p

Why wouldn't this work on a bigger scale though? it could be implemented by Eskom today, without needing to install millions of user devices.
I mean, surely if your town gets cut you will switch off some stuff at least? Especially when it cuts again and you have to sit for another 30 minutes without power. and then another hour. then two.

I really think there is no incentive with the current system. With this new load limiting system there is, even if it functions on a bigger scale.

Could be, not sure on exact areas so far, but last article here I saw mentioned 65k(?) houses on the system already and more added weekly.
