Switching off South Africa's geysers could save up to four stages of load-shedding — Ramokgopa

So are they going to ripple you when it's your 4hours of electricity in a day then while you get loadshed the rest of the time you wanted hot water? :ROFL:

With the stage 4+ load shedding, they are switching off our geysers for 10hrs+ for us anyway. Don't need to do anything.

Sadly I think we are in the minority. I think there are a significant chunk of a people who just leave theirs running all day, either because they're too lazy or just want to make sure their water is hot when the power is actually on.

Why are you calling Craig a lazy guy? He has a logic (and perhaps evidence) Have you ?

No, mine is on permanently. Uses less electricity this way. It uses more units when I switch it on and off as needed. And I'm not taking cold showers.

City power has installed some device at our house (and most units in the complex). One of the electricians said that it is used to monitor and cut off geyser even in non-load shedding circumstances.

No idea if he is just fibbing or real.
 
I minister is a minister of PR and not electricity. We really don't want to hear things we heard since 2006.

Stop corruption. Get generation stable. Make sure the transmission grid has capacity. After those items are done, then go on your ego trip...

Reducing demand must surely be part of that strategy, what is an ego trip about that?

Of course, that is the way, since it has been determined that there isn't corruption.

How about increasing the availability levy a bit? More levy, less electricity. Win.

who cares = got rid of eksdom for water heating long ago - solar geyser with gas geyser to boost during winter - fark eskom!!

If the law says all geysers need a ripple control they are going to switch it off if you got solar or not.

Fuggem. I'd like to see the ripple signal that gets past my Susynk's IGBTs. :D
 
Or they could incentivize installation of heat pumps with a cash back of sorts. They would be ‘building’ a power station without building one.

A normal Kwikot heat pump geyser needs 2000W less than a normal geyser to heat the same amount of water in the same amount of time. So just 500,000 households would be 1GW of power restored. What would this be worth to Eskom?

Say R20,000 cash back per heat pump?

R20,000 * 500,000 = R10,000,000,000

For a Gigawatt (1000MW) power plant….

Or exactly R10,000 per kW.

Not bad I’d say considering it works at night as well as during the day.

Not sure how a double pole isolator would prevent the signal, it's usually a higher frequency than the grid sync itself (175Hz or so).
Ripples were actually great things in the 80s, switch off a whole suburb's geysers in the peak 17H00 to 19H30 timeslot, and rotate it on 30m intervals. Can flatten demand quite well, whilst creating minimal interference in people's lives, if properly planned and executed. It's when they go faulty that it creates an impact, which is why so many ripples are bypassed.

It's not exactly power restored. This does not generate power for them. It only requires them to produce less. And at some point, even that is not going to be good enough.

Yes it should be part of the strategy and has been part of the strategy SINCE 2006. The Minister needs to sort out the big problems and not say easy but ultimate meaningless things. It is like the police minister saying that people should do less crime. True, but absolutely bloody useless.

Doubt if it would even be 1 stage but 4 stages that is a load of BS.


It happened was an eskom scheme, I had one installed through it in 2012. Also had my filament lights switched to led through another scheme iirc 2014 ish, cannot remember if that was municipality or eskom.

> Convert your 200 lt High pressure geyser to solar R11 500
> (You claim back Eskom subsidy of R5000: R11500-R5000=R6500, it takes 8 weeks)
Still working today. Times I actually need electricity for geyser is about 5 days during winter. Its permanently off at the DB

More info on this subsidy?

Minister in the Presidency responsible for Electricity, Dr Kgosientsho Ramokgopa, is expected to visit the Matimba and Medupi Power Stations in Limpopo on Monday.

This is a continuation of the minister's visits to all of Eskom's power stations which began last week. The visits are aimed at engaging management, workers and unions.

Ramokgopa has the IQ of a dead fly frozen in the North Pole.
