Part 4 — Adjustment of certain tariff caps
[Heading inserted: Gazette 18 Oct 2002 p. 5225.]
7. Term used: CPI number
In this Part —
CPI number means —
the Consumer Price Index, All Groups index number, weighted average for 8 capital cities, calculated and published by the Australian Statistician; or

8. General adjustment for 2021/22 financial year and subsequent financial years
This clause applies to the calculation of the fixed component and the usage component or components (other than the usage component to which clause 9 applies) of a charge under this Schedule for the supply of gas in the 2021/22 financial year or a subsequent financial year (in this clause called the relevant year).
If the CPI number for the quarter ending on the last 31 March before the beginning of the relevant year (CPIr) is more than the CPI number for the quarter ending on the 31 March that was a year earlier (CPIr‑1), instead of using the number of cents per day or cents per unit shown in the relevant Table the number to be used for the relevant year is derived from the formula —
where —
Rn is the number of cents per day or cents per unit for the relevant year;
Rn‑1 is the number of cents per day or cents per unit that applied under this Schedule immediately before the relevant year began.
If CPIr is not more than CPIr‑1, the number of cents per day or cents per unit to be used for the relevant year is the number that applied under this Schedule immediately before the relevant year began.

9. Special adjustment for residential tariffs in Mid‑West/South‑West area
This clause applies to the calculation of the third usage component (the relevant component) of a charge under this Schedule for the supply of gas for residential purposes in the Mid‑West/South‑West area in the 2021/22 financial year or a subsequent financial year (in this clause called the relevant year).
If the CPI number for the quarter ending on the last 31 March before the beginning of the relevant year (CPIr) is not at least 2% less than the CPI number for the quarter ending on the March that was a year earlier (CPIr‑1), instead of using the number of cents per unit shown in the relevant Table the number to be used for the relevant component for the relevant year is derived from the formula —
where —
Rn is the number of cents per unit for the relevant year;
Rn‑1 is the number of cents per unit that applied under this Schedule for the relevant component immediately before the relevant year began.
If CPIr is at least 2% less than CPIr‑1, the number of cents per unit to be used for the relevant year is the number that applied under this Schedule for the relevant component immediately before the relevant year began.
[Clause 9 inserted: Gazette 18 Oct 2002 p. 5226; amended: Gazette 30 Jun 2008 p. 3136; 30 Jun 2009 p. 2673; 26 Mar 2010 p. 1145; 29 Jul 2011 p. 3132; 1 May 2012 p. 1844; 17 May 2013 p. 1980; SL 2020/80 r. 4(2).]
