Johannesburg City Power will remotely switch off geysers to alleviate strain on the power grid, a spokesman said on Monday.

"In our effort to reduce the impact of load shedding on the city of Johannesburg, City Power will remotely switch off the geyser control systems to certain areas at specific times to manage the electricity load across the city," spokesman Sol Masolo said in a statement.

He appealed to large power users and business to switch off non-essential machinery, air conditioners, and lights.

Masolo said power utility Eskom had asked the City of Johannesburg and municipalities countrywide to reduce demand by cutting power to their customers for half a day.

Eskom spokesman Andrew Etzinger said they had once again implemented rolling blackouts on Monday until three of their generators could be fixed.

"We have started with stage one of load shedding. Three large generators at our power stations are out of service," said Etzinger.

Eskom however said there would be no power cuts during the week.

Many areas in the country were without power for parts of the weekend as the power utility and its municipal customers implemented scheduled blackouts to build up power reserves for the week.

Etzinger said the cuts would last for most of Monday, but as soon as the generators were back online "things should be better".

Rosebank in Johannesburg had power cuts on Monday morning. Masolo said power in the area would be restored by 10.30am.

"The load shedding is expected to be over by at least 1pm this afternoon."

The power cut schedule for Johannesburg residents was available on www.citypower.co.za .

Good luck. Ripple switch was bypassed long ago. If I had to take one more cold shower I would have lost it.
 
Good luck with that.
Turn my geyser off at the wall already.
 
My geyser pulls 160 watts max. Please don't switch it off.
 
How is that done?

Geysers are installed with a ripple switch. so they send a certain lower frequency signal down the line and the ripple switch switches off the component (in this case a geyser) later on ....if they remember they send the same signal down again and it "ripples" it back on again.

They have actually been switching your geyser on and off for a couple of years now.

What can you do if they forget to switch it back on then?

:wtf: learned something new today. Does all geysers have these?

I think it's usually a higher frequency 1050hz

Sometimes...usually not.
 
Ive been in lots of places in CT which have spaces for these controllers, but they are empty.

I assume it's a 'crime' to by pass them right? Or is that a bit of a grey area?
 
Certain areas of Cape Town have had this for years already. I have also never had to take a cold shower because of it. I suppose it comes down to how it's managed. It's a fantastic idea.
