- (a) bids and offers for electricity are submitted and revised by generators and purchasers; and
- (b) information from the grid owners is submitted and revised; and
- (c) reserve offers are submitted and revised by ancillary service agents; and
- (d) the system operator collects the information referred to in this subpart; and

Compare: Electricity Governance Rules 2003 rule 1 section II part G

13.5 Bids and offers must be lawful

A purchaser, generator or ancillary service agent must not make or maintain a bid, offer or reserve offer if the purchaser or generator or ancillary service agent knows or ought reasonably to know that acting in accordance with the bid, offer or reserve offer would contravene any law.

Compare: Electricity Governance Rules 2003 rule 2 section II part G

Clause 13.5: amended, on 28 June 2012, by clause 6 of the Electricity Industry Participation (Demand-side Bidding and Forecasting) Code Amendment 2011.

13.5A

Conduct in relation to generators' offers and ancillary service agents' reserve offers

(1) In the spot market –
- (a) it is expected that offers and reserve offers will generally be subject to competitive disciplines such that no party has significant market power;
- (b) however, there may be locations where, or periods when, one or more generators, or ancillary service agents, as the case may be, has significant market power.
(2) Accordingly –
- (a) where a generator submits or revises an offer, that offer must be consistent with the offer that the generator, acting rationally, would have made if no generator could exercise significant market power at the point of connection to the grid and in the trading period to which the offer relates;
- (b) where an ancillary service agent submits or revises a reserve offer, that offer must be consistent with the reserve offer that the ancillary service agent, acting rationally, would have made if no ancillary service agent could exercise significant market power at the point of connection to the grid and in the trading period to which the reserve offer relates.
(3) For the purposes of this clause –
- (a) market power becomes significant when its exercise would have a net adverse impact on economic efficiency, which includes productive, allocative and dynamic efficiency;
- (b) “spot market” has the same meaning as wholesale market except that it excludes the hedge market for electricity (including the market for FTRs).

13.39 Inter-relationship between reserve and energy offers

Reserve offers and offers made under clauses 13.38(1) and 13.6(1) to (3) respectively, if they are in respect of the same individual generating unit or individual generating station (as required under clauses 13.10 and 13.11), are inter-related in that the greater the energy dispatched the lower the instantaneous reserve may be and vice versa. Accordingly, an ancillary service agent that is a generator does not breach clause 13.38(2)(c) if the offer quantity under clauses 13.6 to 13.27 and quantity of instantaneous reserve offered under clauses 13.37 to 13.54 are duplicated, and the ancillary service agent must not be scheduled by the system operator and a dispatch instruction from the system operator must not be given the effect of which is that the combined dispatch quantity and instantaneous reserve exceeds the capacity of the individual generating unit or individual generating station, as the case may be.

13.40 Inter-relationship between reserve offers of interruptible load and bids

Bids and reserve offers of interruptible load are inter-related in that demand electrically disconnected in response to an under-frequency event and in accordance with a dispatched reserve offer may lower the quantity purchased at that grid exit point. Accordingly, a purchaser does not breach the reasonable estimate requirement in clauses 13.7(3), 13.7AA(2), and 13.8A(4) if the purchaser is acting as an ancillary service agent and reduces corresponding demand in response to an under-frequency event in accordance with a dispatched reserve offer.

13.40A

Inter-relationship between reserve offers and nominated dispatch bids

Reserve offers and nominated dispatch bids made under clauses 13.38(1) and 13.7(1) to (3) respectively, if they are in respect of the same plant, are inter-related in that the lower the demand dispatched or scheduled the lower the instantaneous reserve may be. The ancillary service agent must not be scheduled by the system operator and a dispatch instruction from the system operator must not be given the effect of which is that the instantaneous reserve exceeds the scheduled or dispatched demand quantity of the dispatch-capable load station, as the case may be.

Clause 13.40A: inserted, on 1 November 2022, by clause 22 of the Electricity Industry Participation Code Amendment (Real Time Pricing) 2022.

13.41 Reserve offers may contain up to 3 price bands

Each reserve offer submitted by an ancillary service agent may, for each type of instantaneous reserve, have a maximum of 3 price bands for each trading period. The price offered in each band must increase progressively from band to band as the aggregate quantity increases.

Rules governing the preparation of interim prices

Cross Heading: amended, on 1 November 2022, by clause 66 of the Electricity Industry Participation Code Amendment (Real Time Pricing) 2022.

13.134A

Methodology for calculating interim prices

The clearing manager must calculate interim prices and interim reserve prices for a trading period in accordance with the following formula:

where

is the interim price or interim reserve price

is the sequential number of a dispatch price or dispatch reserve price in the set n in the trading period

is the total number of dispatch prices or dispatch reserve prices that apply during the trading period

P_t

is the dispatch price or dispatch reserve price as made available on WITS that applies for the trading period at time T_t

T_t

is the start time of the sequential numbered t dispatch price or dispatch reserve price for the trading period, as made available on WITS

but
(a) if there is no dispatch price or dispatch reserve price for t=1 in a trading period, the dispatch price or dispatch reserve price (as the case may be) for the t=1 period is the forecast price or forecast reserve price in the most recent price-responsive schedule received by the clearing manager prior to the start of the trading period; and
(b) if there is also no forecast price or forecast reserve price under paragraph (a), the dispatch price or dispatch reserve price (as the case may be) for the t=1 period is the final price or final reserve price (as the case may be) from the equivalent trading period determined in accordance with clause 13.134B.

Clause 13.134A: inserted, on 1 November 2022, by clause 67 of the Electricity Industry Participation Code Amendment (Real Time Pricing) 2022.

Clause 13.134A: amended, on 1 July 2025, by clause 4 of the Electricity Industry Participation Code Amendment (Backup Interim Price Method) 2025.

13.134B

Equivalent trading periods for interim prices where there is no forecast price or forecast reserve price

(1) Subject to subclauses (2) to (4), the equivalent trading period will be the trading period that falls on the same day of the week and starts at the same time of the day as the t=1 period, in the week before the t=1 period, provided that trading period is not a trading period—
- (a) that falls on a national holiday; or
- (b) that has no final price or final reserve price (as the case may be); or
- (c) in respect of which the Authority has decided to investigate, and is yet to resolve, a potential undesirable trading situation; or
- (d) for which the calculation of the interim price or interim reserve price (as the case may be) under clause 13.134A used a dispatch price or forecast price, or dispatch reserve price or forecast reserve price (as the case may be), from a dispatch schedule or price-responsive schedule that the system operator assigned price and quantity values to under clause 13.69AA or 13.58AA, respectively.
(2) If subclause (1)(a) to (1)(d) applies, the equivalent trading period will be the trading period that falls on the same day of the week and starts at the same time of the day as the t=1 period in the week before the week before the t=1 period, and so on, until an equivalent trading period is arrived at that meets the requirements of subclause (1).
(3) If the t=1 period falls on a national holiday—
- (a) the equivalent trading period will be the trading period that starts at the same time of day as the t=1 period on the closest previous Sunday to the national holiday in respect of which subclause (1)(a) to (1)(d) does not apply; and
- (b) if subclause (1)(a) to (1)(d) applies to that Sunday, the equivalent trading period will be the trading period that starts at the same time of the day as the t=1 period on the next closest previous Sunday to the national holiday, and so on, until a Sunday is arrived at in respect of which subclause (1)(a) to (1)(d) does not apply.
(4) Where, due to daylight savings, the same time of the day does not exist or two such times exist,—
- (a) if the same time of the day does not exist, the next most recent week’s trading period must be used instead; and
- (b) if more than one same time of the day exists, the most recent time must be used.

Calculation of constrained off amounts

13.192 Constrained off situations may occur

(1) A constrained off situation occurs when—
- (a) a generator (other than a dispatch notification generator) is not given a dispatch instruction, or is not dispatched by the system operator to the level expected based on the generator’s offer compared to the relevant final price, for a trading period despite the generator having offered electricity at a price below the final price for that trading period at the relevant grid injection point; or
- (b) in relation to a block dispatch group or station dispatch group, a generator (other than a dispatch notification generator) is not given a dispatch instruction, or is not dispatched by the system operator to the level expected based on the generator’s offer compared to the final price, for the trading period, despite the generator having offered electricity in the trading period at a grid injection point within the block dispatch group or station dispatch group below the final price at the relevant grid injection point in that trading period, and the aggregate quantity of those offers is greater than the dispatched quantity calculated in accordance with clause 13.194; or
- (c) load to which a nominated dispatch bid (other than a dispatch notification purchaser bid) applies is not dispatched, and where the price in the nominated dispatch bid is above the final price at the relevant GXP.
(2) In this clause,—
- (a) an offer made by a generator means the last offer made by the generator which applied during the relevant trading period; and
- (b) a bid made by a purchaser means the last bid made by the purchaser which applied during the relevant trading period.

13.193 Determining affected price bands for block dispatch groups and station dispatch groups

(1) If a constrained off situation occurs for a block dispatch group or station dispatch group during any trading period during a billing period, the clearing manager must determine the affected price bands for that block dispatch group or station dispatch group by—
- (a) taking all the offers made by that block dispatch group or station dispatch group in relation to that trading period, calculating the differences between each offer price and final price for each grid injection point, and ranking the differences in ascending order; and
- (b) identifying each price band ranked under paragraph (a) in which the aggregate quantity in all previous price bands plus the quantity for that price band is greater than 0 or the dispatched quantity calculated in accordance with clause 13.194, but is less than the aggregate quantity for all the generating plant in that block dispatch group or station dispatch group calculated by the clearing manager using the methodology set out in Schedule 13.3. The offer prices corresponding to the ranked price bands identified under this paragraph are the affected price bands for the block dispatch group or station dispatch group for the purposes of clauses 13.194 to 13.196.
(2) In this clause, an offer made by a generator means the last offer made by the generator which applied during the relevant trading period.

13.194 Clearing manager to calculate constrained off amounts

(1) Despite clause 13.193, if a constrained off situation occurs in relation to a generator during a trading period, the clearing manager must calculate the constrained off amounts for each generator, for each affected price band, using the following formula:

COF_g = Q_cof * (P_f − P_o)

where

COF_g

is the constrained off amount for a generator

Q_cof

is the dispatched quantity in MWh (calculated under subclause (3)) from that price band in the offer that was constrained off during a trading period, or the positive difference between the reconciliation information and the scheduled quantity, whichever is less

P_o

is the price offered for that price band by that generator for the quantity of electricity from the generating plant that was constrained off

P_f

is the final price for that trading period at the grid injection point.

(2) If a constrained off situation occurs in relation to a dispatch-capable load station during a trading period, the clearing manager must calculate the constrained off amounts for each dispatch-capable load station, for each affected nominated dispatch bid price band, using the following formula:

ConOffAmt_disp = ConOffQ * ( P_b - P_f)

where

ConOffAmt_disp

is the constrained off amount for a dispatch-capable load station for the nominated dispatch bid price band

ConOffQ

is the amount in MWh by which Q_b exceeds the highest of Q_disp and Q_rec

where

Q_b

is the quantity, in MWh, in the nominated dispatch bid band where the bid price is above the final price

Q_disp

is the dispatched quantity, in MWh in the trading period, calculated under subclause (3), dispatched for the nominated dispatch bid price band in the trading period

Q_rec

is the reconciled quantity provided by the reconciliation manager under clause 15.20C allocated by the clearing manager to the nominated dispatch bid price band in the trading period

P_b

is the price bid for the nominated dispatch bid price band for the dispatch-capable load station that was constrained off

P_f

is the final price for the trading period at the grid exit point.

(3) For the purposes of clauses 13.192 to 13.201, dispatched quantity must be calculated taking into account—
- (a) the quantity in MW recorded in the log kept by the system operator in accordance with clause 13.76 and, if required, the clearing manager must aggregate such quantities for—
  - (i) generating stations or generating units in the relevant station dispatch group; or
  - (ii) generating units, if the clearing manager requires the dispatched quantity to be determined on a grid injection point basis; and
- (b) for an offer, the ramp rate applying to that constrained off situation that is specified in the offer submitted by that generator, or—
  - (i) for a block dispatch group or a station dispatch group; or
  - (ii) for generating units, if the clearing manager requires the dispatched quantity to be determined on a grid injection point basis—
- the fastest of the ramp rates applying to that constrained off situation that are specified in the offers submitted by the generator in that block dispatch group, that station dispatch group or those generating units electrically connected to the relevant grid injection point (as the case may be); and
- (c) plus or minus the MW bandwidth applicable for each generator affected by a frequency keeping requirement as advised by the system operator to the clearing manager, and, if required, the clearing manager must aggregate the MW bandwidth applicable to determine the MW bandwidth on a grid injection point basis.
(4) In this clause,—
- (a) an offer made by a generator means the last offer made by the generator which applied during the relevant trading period; and
- (b) a bid made by a purchaser means the last bid made by the purchaser which applied during the relevant trading period.

- (b) the load weighted contract price in accordance with subclause (3).
(2) The time weighted contract price is to be calculated in accordance with the following formula:

where

CP_tw

is the time weighted contract price

is the number of different prices within the contract

P_i

is the price specified in the contract

TP_i

is the number of trading periods during which each price in the contract applies

is the location factor, for the relevant node at which the price is set in the contract, as published by the WITS manager in accordance with clause 13.221

LAF

means a loss adjustment factor, which is,—

(a) if the time weighted contract price for the contract is referenced to a point of connection on the grid, 1; or
(b) for all other contracts, 0.937 (being the difference between 1 and the loss factor of 0.063).

(3) The load weighted contract price is to be calculated in accordance with the following formula:

where

CP_lw

is the load weighted contract price

is the number of different prices within the contract

P_i

is the price specified in the contract

V_i

is the volume of electricity for each trading period during which each price in the contract applies

is the location factor, for the relevant node at which the price is set in the contract, as published by the WITS manager in accordance with clause 13.221

LAF

means a loss adjustment factor, which is,—

(a) if the load weighted contract price for the contract is referenced to a point of connection on the grid, 1; or
(b) for all other contracts, 0.937 (being the difference between 1 and the loss factor of 0.063).

(4) Where a risk management contract includes prices at more than 1 node, the WITS manager will calculate the time weighted contract price and load weighted contract price at each node.
(5) To avoid doubt, if a risk management contract includes an adjustment clause, the time weighted contract price and load weighted contract price is that which applies before the adjustment clause takes effect.

Requirement to quote

(1) Subject to subclauses (2) to (5), the participant must, for a minimum of 25 minutes in every NZEF market-making period, provide quotes for a minimum of—
- (a) 24 monthly NZ electricity futures for each of the Otahuhu reference node and the Benmore reference node (being 24 buy quotes and 24 sell quotes for each reference node) for the current month and each of the five months following the current month; and
- (b) 24 quarterly NZ electricity futures for each of the Otahuhu reference node and the Benmore reference node (being 24 buy quotes and 24 sell quotes for each reference node) for each calendar quarter that is available for trade on an exchange.
(2) The participant must not provide a quote under subclause (1) with a bid-ask spread that exceeds the greater of 3% or NZ$2. For the avoidance of doubt, where there are multiple buy orders and sell orders for a particular reference node for a particular month or calendar quarter in a NZEF market-making period, the requirement in this subclause means the bid-ask spread between the lowest priced buy order and the highest priced sell order (across those multiple orders) must not exceed the greater of 3% or NZ$2.
(3) Under subclause (1) for each NZEF market-making period, the participant must provide a quantity of initial quotes and (as applicable) volume refresh its quotes until it has traded the total required volume for each of the Otahuhu reference node and the Benmore reference node in relation to each particular month and calendar quarter as follows:
- (a) when first placing orders at or after the start of the NZEF market-making period, the participant is required to place a buy order of at least 12 quotes in total and a sell order of at least 12 quotes in total:
- (b) if either initial buy order or sell order is fully traded then that participant must (as applicable) volume refresh its order(s) such that where the amount of the total traded NZEF up to that point in time in the NZEF market-making period is—
  - (i) 12, then at the end of the volume refresh period the buy order must comprise at least 12 quotes and the sell order must comprise at least 12 quotes:
  - (ii) greater than 12, then at the end of the volume refresh period that participant must ensure that the number of quotes comprising each of the buy order and sell order respectively are a minimum of X, where—

X = 24 quotes – total traded NZEF

- (c) once the participant has traded the total required volume it may withdraw any remaining quotes.
(4) A participant required to volume refresh in accordance with clause 13.236L(3)(b) may also carry out any other changes not inconsistent with their obligations under this subpart that the participant chooses to make to any other order(s) for the particular month or calendar quarter and particular reference node that is the subject of the volume refresh.
(5) For the purpose of determining whether a participant has met the minimum time requirement of 25 minutes under clause 13.236L(1), a quote will not be treated as being provided during a volume refresh period.

Exemptions from requirement to quote

(1) The participant is exempt from the requirements in clause 13.236L in the following circumstances:

- (b) in addition to the exemptions in paragraph (a), for up to two NZEF market-making periods within any 20 consecutive NZEF market-making periods at the participant’s discretion.
(2) To avoid doubt, if the participant meets the criteria for exemption in subclause (1)(a)(i) or (1)(a)(ii) in relation to a NZEF market-making period, that NZEF market-making period will not count towards the participant’s two exemptions in subclause (1)(b).
(3) If the participant relies on an exemption under this clause 13.236N from the requirement to quote, the participant must notify the Authority of the exemption it has relied on and the basis for the exemption as soon as practicable but in any case no later than 1700 New Zealand time on the same business day that an exemption is relied on.
