What codes are used on an Atlas MK7A meter in South Australia

[tellmenolies]

What do the codes 07, 03, 13, 43, 53, 63 represent on a Atlas MK7A meter ?

@NeilC ok so demand intervals don't determine kwh charge for each hour, but for the whole billing cycle.

More and more intricate (confusing) type billing.

So that wouldn't work for an EV charging situation if doing so at night (on 8c tariff), as peak demand during that is 11.7kw.

 SAPN registration was straight forward, and got my NMI / main meter inputted for TOU and solar feed in.

But went to put in the CL TOU meter number, but as it has the same NMI, it wouldn't allow me to register the 2nd meter.

Not sure if I can overcome this, but just having the SAPN figures there is a help.

I will download the data sometime to take a look.

@Lester 

You missed a few things here.

You get charged the MAX Demand for the HIGHEST day for the  WHOLE month.

Say you are on 5min readings (which I suspect that when you look at your SAPN files you will be ) and you use .8kW for one 5min interval, you will be charged 9.6kW for your demand charge FOR THE WHOLE MONTH.

I am in the process of adding the DEMAND daily figure to my programme just to see what its like.

Here are our daily statistics from our last billing period

Daily Statistics
2.991 kWh	From Grid
27.154 kWh	Exported
4.364 kWh	Generated  used
31.518 kWh	Daily Generation

For the month Dec 23. which is in the last billing period, we would have have to pay a demand rate for 2.904 kW for the whole of that month, which you may note, is nearly our average daily usage.

The Generated used includes heating our hot-water.

@NeilC I think I got that thought adjusted in my second post, just before your reply . . . that's only for demand tariff though yes ?

AFAIK, TOU is charged per KWH in the relative tariff blocks.

Just checked online and it appears so.

We are on simple TOU with CL TOU 2nd meter.

I found that SAPN download does show the 2 meters, no need to register the 2nd one to the same NMI.

If Demand and TOU are different animals, as I suspect (hope !), I will obviously be staying on TOU with solar and (soon to install) battery.

@Lester 

No such thing as a simple TOU.

You have peak, off peak and shoulder.

In SA:

PEAK is from 00:00 01:00, 06:00 till 10:00 and lastly 15:00 till Midnight.

OFF PEAK is from 01:00 till 06:00

SHOULDER is from 10:00 till 15:00

The Controlled load times have different hours but have three levels as well.

Demand Tariff is a single rate all day and your calculated DEMAND RATE is added during the billing process.

You can see all the different tariffs on the EnergyMadeEasy web site as applicable from all the RETAILERS available in SA.

You can also see all the rates for each state if you so desire.

As at 05:54 EDST:

And above is my usage for the current billing cycle

[Lester]

Yep, I know about the flat rate (can't go back once you go to TOU), TOU normal and TOU CL, and Demand tarrif from the AGL site.

Looked it up after my first reply to you and reposted follow up.

Again, we are on TOU and CL TOU.

Reading through that the other day I realised if you use a major power draw like EV charging, Demand is just something to keep well clear of.

I also use some machinery which would no doubt draw a lot, welder, compressor, etc and make the peak demand points very high. 

Hard to imagine it makes any sense going Demand tariff for anyone with those peaks.

Not sure where you got the block times in the reply above . . .

Peak for me is just 2 blocks, 0600 - 1000 and 1500 - 0100.

Off peak is 0100 - 0600.

Shoulder is 1000 - 1500.

CL TOU is another story with 3 different time blocks in similar peak, off peak, and shoulder rates, all that are slightly less than regular tariffs.

Shoulder (during the day while solar is doing it's job) is cheaper than off peak, wouldn't you know it ?

EV night saver tariff overrides all other tariffs between 1200 - 0600, and charge out ALL power into the home in this time at the exceptionally low rate per kwh.

All times AEST.

Just had a meter installed and it has 2 of the 03 codes one reads 2.1kwh and the next reads 2.2kwh 07 is 1.1 and 53 is 3.3 

13 and 63 read 5.8
