11/12th’s Data
This year we will only be distributing 11/12ths (Sept 13 to July 14) capacity measurement figures if there is a significant variances from the previous years capacity measurement data.
In late September you will be provided with a full year’s metering data for each of your connection locations, and reports showing determinations of your relevant AMI, AMD, HAMI and RCPD. This will be uploaded to your secure ‘My Transmission’ area for your review.
8
• The full year’s reports and data will be available late September• If we are advised of any potential errors/omissions we will review, fix
and upload in the provisional column and you will be advised• Once allocations are confirmed, we will move all reports/data files to
final and no further action is required until the Publish Prices stage

Determining AMD:
AMD is the average of the 12 highest net off-take quantities, based on a ranking of
½ hour periods from ‘1st Sept period 1’ to ‘31st August period 48’
•The same process is used to determine AMI, but using net injection quantities
• AMI and AMD are used to apportion connection charges for shared substation assets

Determining HAMI
HAMI only applies to South Island Generation Customers and is onlydetermined for customers qualifying connection locations. The 2015HAMI is determined by calculating the average of the 12 injection peaks foreach South Island Injection connection location for each of the following HAMIassessment periods:
1 Apr 2011 to 31 Mar 20121 Apr 2012 to 31 Mar 20131 Apr 2013 to 31 Mar 20141 Sep 2013 to 31 Aug 20141 Apr 2014 to 31 Aug 2014
The highest average of the five HAMI assessment periods is the 2015 HAMI forthe customer.

Determining RCPD
RCPD is used to calculate interconnection charges for each customer at each of their
connection locations as per the following example for a (fictional) USI customer.
RCPD is determined by aggregating customer off-takes at each off-take customers connection location in each region, during the N regional peak demand periods, where N = 12 in the Upper North and Upper South regions and N = 100 in the Lower North and Lower South regions.

Exceptional Operating Circumstance (EOC)
If when calculating AMD, AMI, HAMI and RCPD quantities prior to the start of
the pricing year, Transpower, in its sole discretion considers that an
exceptional operating circumstances has occurred, it may adjust AMD, AMI,
HAMI and or any RCPD as per clause 34 of TPM.
17
Raw Data we are providing:
As well as the AMI, AMD, RCPD and HAMI reports, Transpower will also be
providing a CSV data file with all ½ hour metering data for your connection
locations. Each dataset has 17,520 (365 * 48 ½ hour periods) rows.
This is the data used to determine AMI, AMD, HAMI and RCPD. If you wish,
you can use this data to confirm that our calculations are correct.
18
Checking
Please check your reports and data for reasonableness and to ensure
we have captured all abnormal events at your connection locations.
The AMI, AMD and HAMI results should not change unless you have
identified an issue, however the RCPD report content may change if
other customers have identified issues in your region.
Once you have checked your data and reports, please provide
feedback via the online form.

A walkthrough for Publish Prices will be provided closer to the time.
