Agents, third parties, and new entrant retailers have asked for information about metering configurations at ICPs throughout the country. These parties are investing in systems and processes, and it’s helpful for them to know all of the options up front rather than discovering each unique configuration one-by-one as they engage with consumers or use the ICP connection data API.

We’ve released a file detailing unique metering configurations at ICPs and the number of ICPs with each configuration. This information is provided at meter register level for any active meter in the registry at any installation at active ICPs. The register information is provided as a space delimited list with energy flow direction, register content code, and period of availability. More information can be found in the registry functional specification.

The file will be updated and released with other retail reports each month. As with all files in the datasets folders, they are also accessible via our FTP site.

Is there any good reason for having 1580 I flow registers allocated against UN / D / N etc content codes?

I guess my main issue is with PV registers that may typically be allocated PV1 profile having UN24 register codes in place of EG24.

On another note, interesting to see a number of zero hour registers. Suspect these are three phase meters installed in place of two single phase meters.

Following on from this, is there a report that indicates the number of whole meters not used for submission?

No - after looking into this, there is no good reason. This is an MEP compliance issue - I'll pass it to the right people internally.

For injection meter registers can only be:

I-7304-24 (with an HHR profile code populated by the trader), or;
I-EG-24 (with a PV1 or EG1 profile code populated by the trader)

Zero is not a valid period of availability. A UN register content code must always be 24. If the register is programmed or exists it should show in the registry. However, observing this in the registry data would not tell you if that channel was connected to any actual load (or any injection source), to see this you'd need to look at the consumption data for the ICP.

There is no report that lists the numbers of separate installations or separate meters installed behind ICPs that are held in the registry. We thought the most value was captured by reporting register details of all installations and meters at each ICP - and how common these arrangements are. Other meters at ICPs that are not used for reconciliation won't have details held in the registry.

If you can explain a bit more about the value in this we would consider this.

For these combinations I have to scratch my head a bit:

X-EG-24 (generation, but not into the network???)
X-UN-12
X-UN-16
X-UN-18 (uncontrolled, but not available for more than 18 h per day???)
X-N-24 (a really long night?)
X-N-22
X-N-20 (night lasts 20 h per day?)
X-N-16
X-NC-24 (night register, fully controlled, but not controlled?)
X-CN-24 (controlled but available 24h per day?)

To a lesser extent, the following appear to be a bit odd:

X-SENW-10 (10 hours weekdays, 24 h weekend)
X-SEOP-18 (7.5 h per weekday)
X-SEOP-24 (7.5 h per weekday)
X-SEPK-24 (6.5 h per weekday)
X-SWDD-24 (weekday day)
X-SWDN-24 (weekday night)
X-SWDPK-24 (8 h per weekday)
X-SWED-24 (day weekend)
X-SWEN-24 (night weekend)
X-WD-8 (day is 8 hours only?)
X-WDOP-24 (off peak is 24 hours a day?)
X-WE-8 (the weekend only has 8 hours per day?)
X-WE-10
X-WE-14
X-WE-16
X-WWDD-24 (winter weekday day is 24 h - what about night?)
X-WWDN-24 (winter weekday night is 24 h - what about day?)
X-WWDPK-24 (peak period is all day?)
X-WWED-24 (winter weekend day is 24h? - what about night?)
X-WWEN-24 (winter weekend night is 24h? - what about day?)
X-NC-20 (can night be 20h?)
X-NC-19
X-NC-17

Apologies for the delay in replying to this post. Most of the combinations listed above are incorrect, we are investigating these along with a few others currently.

Regarding whole meters not used for submission, my interest is to find out how many meters are active, but submit no volume due to discontinued channels. In particular meters that have no connection to customer load.

The registry contains metering information to the register level, however, market systems currently only require aggregated electricity volume information.

The only participants that would be able to determine "how many meters are active, but submit no volume due to discontinued channels", is the metering equipment provider and the retailer/purchaser.

I'm interested in finding out how many meters are deployed that are redundant due to legacy channels no longer being used.

Shouldn't there be business rules to prevent creation in the registry of meaningless content codes such as CN-24 or N-24? There's a great deal of unnecessary complexity in wading through so many different configurations when some combinations are invalid.

We are currently consulting on proposed changes to the register content codes and how they are updated/used in the registry. All submissions are welcome, the closing date is Friday 29 September. Details are on our consultation page.

Thanks Nicole, we have submitted. I've taken the Metering Configurations file and reworked it to provide some insights.

It’s certainly time for some consolidation of register content codes and hours of availability. How many networks cut different tariff rates for different hours of availability for controlled load registers?

Can one of the Authority staff please explain why there is no October update of the metering configurations file published yet.

Has this been delayed or postponed, perhaps wishing to avoid the effects of "garbage in, garbage out" as alluded to in the submission I made concerning register content codes, including thousands of non-existent meters and their associated register content codes, at least on TLC's network?

As of today, 26 October 2017, the last update was on 15 September. I understood an update was published on the 15th of each month.

Thanks.

Hi Clive,

Thank you for making us aware of this. The September files are now available.

We had a small issue occur in our data warehouse that happened to coincide with the automated processing that runs after the 10th business day each month. We hadn’t realised this had impacted any published files. This issue impacted all the monthly files published in retail datasets, not only the metering configurations file.

One of the reasons EMI exists is to support users to provide informed consultation responses. It’s great to hear that you’re making use of this information in this way.

To be clear, the files are published after the 10th business day - this is not always the 15th of each month.

Cheers,

Matthew
