Re: Demand rates

@NeilC @jaydeny, @David_AGLNow we're starting to get somewhere and are beginning to understand each other on this topic. I joined this forum largely so that I could figure out how the charges were calculated, bearing in mind that at this moment most consumers, me included, aren't yet on a demand tariff. Clearly you have the advantage(?) of being on it already, so are familiar with it. The SA Power Networks explanation which you provide states it clearly and succinctly. Why are AGL unable to ...

Re: Demand rates

Actually I finally have it worked out, but the problem lies with your explanation. Basically, it omitted one vital step which I have bolded below. Try this for an alternative:The meter will detect the 30 minute period between 4pm and 9pm when the usage (in kWh) within the month is highest. This value then gets doubled to arrive at a figure which represents the average power demand in kW over that time interval. That is the figure which the retailer multiplies by the demand tariff to arrive a ...

Re: Demand rates

Thanks @NeilC . Well, actually I do have a very good understanding of the difference between kW and kWh, so there's no need to lecture me on the basics. I spend a lot of time analysing and spread-sheeting my usage and studying the output from the smart meter attached to my solar installation. However your explanation still doesn't clarify the situation. Let's take your example where I draw 13kW for 30 minutes. If that were a constant 13kW for the full 30 minutes then it would all make sense. ...

Re: Demand rates

@ith all due respect, @NeilC, you’re missing the point of this hypothetical scenario. I don’t doubt the logic of your argument regarding a short-circuit but maybe I should have chosen a different example to illustrate my point. Supposing on a given day I switch on our ducted air conditioning, clothes dryer, oven and pool filter simultaneously during that peak demand period. Within half a minute or so I realise that the power usage has shot through the roof so I immediately switch off every one ...
