Tarrifs at the end of the day is what drives everything ... well in SA ... load shedding seems to make people move into silly spending sprees because of bad planning ... Hence the suddenl price hikes ... controlled by supply and demand
Something I found very interesting while trolling the web.
As we are all aware ... electricians are sort of "forced" into installing backup system which cannot cope with the total load ... so what happens ... the power drops and either the generator stalls or the inverter consumes the power in the batteries in a short period of time ... sometimes damaging the batteries or the inverter cuts out due to overload.
We have all heard the same story ... "I will spwitch off the geyser ... kettle ... tumble drier ... toaster ... microwave etc etc etc" if the power switches off.
How cool would it be if the system in your house of building was smart enough to controll via and app ... so you want to boil the kettle ... however the fridge and deep freeze are running ... but its a cool winters day ... so you dont need the fridge to run 24/7 ... just imagine how cool it would be if you could switch the load from the fridge freezer to the kettle by the swipe of a tab on your tablet mounted on the wall or your smart phone ... once the kettle boils ... it switches back to the fridge freezer ... or lets say you are in the lounge with the aircon running ...but decide it time to go to bed ... however the house is wired essential or non essential ... and your bedroom or lounge is non essential ... by using a smart system ... you wouldnt need essential and non essential loads ... but rather move the load to other circuits.
I need to shut down my electrical bussiness (my 30 year goal is complete) find someone with money to invest and start a new exciting venture ... making smart homes complete with backup systems which dont rely on eeeeishkom ... and are super energy efficient.
From load profiles I have done in houses ... 5-15 amps is about the average power consumed ... people have got smart and moved to gas stoves and geysers ... lighting is now LED
with many varients of colour (warm... daylight and cool white and many in between) ...which has reduced the total load requirement from 60 amps as supplied back in the old days.
The reality ... its time to get smart.
