(11) Delete the existing clause 7A.3.17 and replace it with the following—

7A.3.17. Where AEMO determines a Forecast BMO under clause 7A.3.16, AEMO must provide to each Market Participant the Balancing Quantities expected to be provided by that Market Participant for each future Trading Interval in the Balancing Horizon.

(12) Amend clause 7A.3.21(c) by deleting the words “received from System Management” and

replacing them with the words “determined (in its capacity as System Management)”.

69. Market Rule 7A.4 amended

(1) Delete the existing clause 7A.4.2 and replace it with the following—

7A.4.2. Subject to clause 7A.4.3, AEMO must, as soon as reasonably practicable after receiving

the information specified in clause 7A.4.1—

(a) determine whether the Facility should be rejected as a Stand Alone Facility due to potential impacts on the performance of System Management Functions in relation to the SWIS if the Facility were to become a Stand Alone Facility, and if not, must otherwise accept the nomination; and
(b) [Blank]
(c) [Blank]
(d) [Blank]
(e) notify Synergy of AEMO’s decision.

(2) Delete the existing clause 7A.4.6(a) and replace it with the following—

(a)

determine whether it should reject the nomination in light of the trial, having regard to any potential impacts on the performance of its functions in relation to the SWIS if the nominated Stand Alone Facility permanently becomes a Stand Alone Facility, and if not, must otherwise accept the nomination; and

xi. the DSP Ramp Rate Limit for each Trading Interval, and the rate at which the Facility is expected to increase its consumption when dispatch ends, as a function of output level, if applicable;

(3) Delete the existing clause (h)(xii) and replace it with the following—
xii. emergency ramp up and ramp down rates, if applicable (which information does not limit a request under clause 7.7.3B);

(4) Delete the clause (h)(xiii) and replace it with “[Blank]”.
(5) Amend clause (h)(xiv) by deleting the full stop and inserting “; and” instead.

(6) Insert new clause (h)(xv) as follows—

xv. a good faith forecast of a consumption profile or profiles at which the Facility is likely to operate for the rest of the Trading Day, if it is issued a Dispatch Instruction by System Management in accordance with 7.6.1H (eg. a Market Participant may provide different profiles to reflect different operation depending on the time of day at which the Dispatch Instruction takes effect).

68. Appendix 5 amended

(1) Delete the existing Step 10 and replace it with the following—

STEP 10: The Individual Reserve Capacity Requirement of Market Customer i for Trading Month

n of a Capacity Year equals (X(i) × Total_Ratio) where—

Total_Ratio = RR_Transitional/Y
Y = Sum(i,X(i))
RR_Transitional is equal to the lesser of—
(a) the Reserve Capacity Requirement; and

(b) the sum of all Capacity Credits minus DSM Capacity Credits

(2) Insert new Step 11 as follows—

STEP 11: The Individual Reserve Capacity Requirement Contribution of an individual metered

Associated Load for Trading Month n of a Capacity Year is determined as follows—

(a) for meter u at an existing connection point measuring Non-Temperature Dependent Load equals (NTDL(u) x NTDL_Ratio x Total_Ratio);
(b) for meter v at an existing connection point measuring Temperature Dependent Load equals (TDL(v) x TDL_Ratio x Total_Ratio);
(c) for meter u at a new connection point measuring Non-Temperature Dependent Load equals (NMNTCR(u) x Total_Ratio); and
(d) for meter v at a new connection point measuring Temperature Dependent Load equals (NMTDCR(v) x Total_Ratio).

69. Appendix 10 inserted

(1) Insert new Appendix 10 (including the footnote) as follows—

Appendix 10: Relevant Demand Determination

This Appendix sets out the 5th percentile methodology for determining the Relevant Demand for
each Demand Side Programme, for use in clause 4.26.2CA(a).
The Relevant Demand value is to be re-calculated for each Demand Side Programme for each

Trading Day.

Step 1

Identify the 200 Calendar Hours in the previous Capacity Year with the highest Total Sent Out

Generation. The Calendar Hours do not have to be contiguous.

Step 2

For each Demand Side Programme, for each Calendar Hour identified in Step 1, for each of the

Demand Side Programme’s Associated Loads, identify the quantity (expressed in MWh)[3] equal to—

[3] On this occasion, the MWh number does not get divided by 2, because measurement is across a full hour,

(a) unless paragraphs (b) or (c) apply, the Associated Load’s metered consumption for the two
Trading Intervals in the Calendar Hour; or

(b) unless paragraph (c) applies, if the Associated Load’s metered consumption is not
available or is considered by AEMO to be inappropriate, a quantity determined by AEMO
based on—
i. available Meter Data Submissions; or
ii. Load information provided by the Market Customer; or
iii. other relevant information; or

(c) if a Market Customer provides evidence satisfactory to AEMO that the Associated Load was operating at below capacity due to its consumption being reduced at the request of
System Management or because of maintenance, AEMO’s estimate of what the
consumption of the Associated Load would have been if it had not been reduced.

Step 3

For each Demand Side Programme, for each Calendar Hour identified in Step 1, sum the values

determined under Step 2 across all the Demand Side Programme’s Associated Loads.

Step 4

For each Demand Side Programme, rank the 200 values determined under Step 3 from lowest to highest.

The Demand Side Programme’s Relevant Demand is the tenth lowest value.

PART 4

70. Market Rule 2.17 amended
(1) Insert a new clause 2.17.1(bA) after clause 2.17.1(b) as follows—
(bA) clause 2.29.5LA;
(2) Delete clause 2.17.1(t) and replace it with “[Blank]”.
(6) Insert new clause 2.17.1(uA) after clause 2.17.1(u) as follows—
(uA) clause 4.11.13;
71. Market Rule 4.11 amended
(1) Insert new clauses 4.11.13-4.11.17 as follows—
4.11.13. If, for a Demand Side Programme that has already been assigned Capacity Credits for a
Capacity Year, AEMO becomes aware of information which causes AEMO to believe that—

(a) the Demand Side Programme may not be able to satisfy the test in clause 4.11.1(j)(ii) in respect of the Capacity Credits; or
(b) the time required by the Demand Side Programme to start reducing its consumption in response to a Dispatch Instruction under clause 7.6.1C(e), is such that, if it received a Dispatch Instruction under clause 7.6.1C(e) requiring it to start reducing its consumption from a time 2 hours after the Dispatch Instruction is issued, the Demand Side Programme would be unable to comply,

then AEMO must, as soon as reasonably practicable and in any event within 30 days after
becoming aware of the information—
(c) disclose the information to the Market Participant; and

(d) after allowing the Market Participant a reasonable opportunity to provide information in response, reassess the assignment of Certified Reserve Capacity to the Facility; and
(e) if the information referred to above would have resulted in AEMO assigning a lower, non- zero level of Certified Reserve Capacity to a Facility, reduce the Capacity credits assigned to the Facility accordingly and advise the Market Participant.

4.11.14. Clause 4.11.13 does not create any obligation for AEMO to investigate a Demand Side
Programme.
4.11.15. An adjustment of Capacity Credits under clause 4.11.13 will not cause any recalculation
of the Reserve Capacity Price and the DSM Reserve Capacity Price.
4.11.16. If AEMO reduces the DSM Capacity Credits assigned to a Demand Side Programme
under clause 4.11.13 then, subject to clause 4.11.17, the Market Participant may (including after
providing new or further information to AEMO) request AEMO to further reassess the
assignment of Certified Reserve Capacity to the Facility. AEMO may after such further
reassessment reinstate some or all of the Capacity Credits, in which case it must advise the
Market Participant as soon as reasonably practicable and in any event within 30 days after the
request.
4.11.17. A request under clause 4.11.16 may be made only once, in respect of a given reduction
under clause 4.11.13.
72. Market Rule 4.25 amended in some circumstances
(1) If at the time this amending rule commences, Schedule B Part 3 of these amending rules has
already commenced, amend clause 4.25.4E by inserting the words “or 4.11.13” after the words “clause
4.25.4C”.
———————————

Side Programme is assigned 10 Capacity Credits. the Calculated DSP Quantity would be 10 x (2+0.5), which equals 25MWh.

ie. 2 Trading Intervals.
