Power system in peril this winter: Eskom

Bring back our electricity , we are paying enough
 
Here's to hoping my collection of gas bottles outlasts the impending gas shortage too.....
 
When is Eskom's power system NOT in peril? Every time we hear from them ... they complain..
 
at least they'll make sure the streetlights and highways stay brightly lit in the day as well.
they aren't really serious about saving electricity, or they could've already fired the moron that advocates daylight-streetlights, and started saving that electricity for night time

Electricity supply doesn't work like that. It's an on-demand service, they cannot store that power for later use. Obviously they could if they had large battery banks but that's just not feasible.
 
That apc will power your laptop for around 10 or so min. Get a 2kva ups and a 110ah deep cycle battery

They can to a certain extent with pumped storage schemes where they use water from 2 dams and pump it to the higher level during non peak times and use it to generate power during peak times I know we have a few systems like that in SA.
 
Preamble to another request to rise in cost! Expect major "Load Shedding",

I highly doubt that. We have the 1500kVa at our office that powers 2 servers/routers/switches for about 20 minutes.

It is the size of the battery and not so much the Kva. E.g that APC has 2 x 7.5Ah batteries. If you wanted to power 100watts that would equate to 0.75hours max backup time. It all depends on what you are powering and how much power they draw. A laptop and a router would probably equate to <40watts so +-2 hours. However some laptops use >50watts...so it all depends

yeah i realise that, but surely if they dont have such extra high, uneccesary, demand, they don't need to provide for it, save on fuel costs? same as with the cellphone chargers, and TV-on standby, that they keep pushing us for.
helluva lotta cellphone chargers dont even come close to one of the N1 floodlights :)
