Can't believe people are calling this a stupid idea.

Can't believe that this brilliant idea is not implemented as planned.

Why don't city power send out SMSs as they said they would?
Why don't they give "training" or at least a leaflet on how they will implement this?
Why do they set the treshold so low that you can't boil a kettle?

So you may be correct the idea is fine the implementation isn't!

In general, not speaking for my house - quite high. Geysers, pool pumps, security lighting, anything else that can run on a timer...

I don't use electricity for heating water at all - but somehow the house hit 9KW the other day.
2kw for aircons, 1 for pool pump, 1 for microwave, 700 watts for "background stuff" and I can only assume the tenants in the cottage were doing something daft.

Im currently (no pun intended) on 1.37KW, pool pump, 2 xfridge/freezer combo, Chest freezer, this PC, a few florescent lights.

Why are you drawing so much current when no one is home? And to be honest, loadshedding starts at 4pm most days or is on weekends...

I go out on weekends...

Possible scenario:
Have a shower
Put on a load of washing
Put on the dishwasher
Go and do chores/shopping/go watch cricket match/go sailing etc.

That's 8kw there EASY. Before pool pumps or anything kick in.

Ok
Geyser will reheat for 30 mins
Washing machine not realy power hungry
Dishwasher maybe 45 mins
After that you safe
Exept if pool pump and geyser kicks in at same time

Washing machine has a 3kw element for heating the water.

So you would rather have no power, than some power?

I'd rather have the load limiting implemented properly. Put relays on geyser, stove and pool pump circuits and switch those off centrally.
Repeated power cycling is BAD.

My problem is principally being screwed over for using a service I pay for. Switch off the buggers that don't pay. Start there. Then and only then will I even consider this even remotely a good idea.

This is just the start. Smart grid technology is coming and the appliance makers are adapting. Prepare for a world where instead of actually maintaining the grid Eskom controls your appliances so you can only make a cup of coffee between 10am and 4pm and no showering after 6am...

Example:
“Whirlpool has committed to make all of its appliances smart grid-compatible by the end of 2015.."
http://www.ecmag.com/section/miscellaneous/most-consumers-dont-understand-how-smart-grid-works

"Peak curtailment/leveling and time of use pricing
To reduce demand during the high cost peak usage periods, communications and metering technologies inform smart devices in the home and business when energy demand is high and track how much electricity is used and when it is used. It also gives utility companies the ability to reduce consumption by communicating to devices directly in order to prevent system overloads. Examples would be a utility reducing the usage of a group of electric vehicle charging stations or shifting temperature set points of air conditioners in a city. To motivate them to cut back use and perform what is called peak curtailment or peak leveling, prices of electricity are increased during high demand periods, and decreased during low demand periods. It is thought that consumers and businesses will tend to consume less during high demand periods if it is possible for consumers and consumer devices to be aware of the high price premium for using electricity at peak periods. This could mean making trade-offs such as cycling on/off air conditioners or running dishes at 9 pm instead of 5 pm. When businesses and consumers see a direct economic benefit of using energy at off-peak times, the theory is that they will include energy cost of operation into their consumer device and building construction decisions and hence become more energy efficient."

Glad I'm still on prepaid, every one else around here didn't want to switch to prepaid so now they got smart meters. Not that we use more than 30A at any given time anyway.

This is truly scary. Imagine Eskom deciding what temperature your heater / air con may be. You can only have lights when there is no sunlight.

“In the first two weeks, household usage will be limited to 21 amps between 7pm and 10pm during peak hours when the grid is generally under severe constraint. After this period, load limiting will run concurrently with the loadshedding schedule which will be published on the City Power website"


This means no cooking for people with smart meters after 7pm for the next 2 weeks.

What a load of ****ing bollocks.

That is such bull****. What about houses that have a tenant in a cottage? These people need to rethink the implementation
