8. Example of Confirm Allocations Page
SIMI and HAMI will be combined as one report from PY2017/18. HAMI will cease to exist from PY2020/21.
The full year’s reports and data will be available in the middle of September together with the asset reports
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

9. 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

10. Example AMI/AMD Reports An AMI and/or AMD report will be provided to each customer showing all of its locations where net injection and/or net off-take has occurred in any ½ hour period within the capacity measurement period

11. Determining HAMI and SIMI
HAMI and SIMI only apply to South Island Generation Customers. HVDC charge will be 100% SIMI charge starting PY

12. Example SIMI/HAMI Report

13. Determining RCPD
RCPD is used to calculate interconnection charges for each customer at each of their
connection locations. RCPD is determined by aggregating net off-takes of each customer in a connection location, during the 100 regional peak demand trading periods of the Capacity Measurement Period but excluding periods from 1 Nov to 30 Apr except for the USI region.

14. Example RCPD Report (a 4-page report but below shows only the first and last pages)

15. Exceptional Operating Circumstance (EOC)
If when calculating AMD, AMI, SIMI 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, SIMI and or any RCPD as per clause 34 of TPM.

16. Raw Data we are providing:
As well as the AMI, AMD, RCPD, HAMI and SIMI 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, SIMI and RCPD. If you wish, you can use this data to confirm that our calculations are correct.

17. 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.

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