industry that recommendations are suitable. of the gas day Noted the AEMC recommendation in the Final Determination for the National Gas Amendment (Gas day harmonisation) Rule 2017 is to harmonise all markets to have a start of gas day at 0600 AEST in 2021. Discussed the implications for harmonising the start of gas day time given the various time zones that the pipelines cross, especially in daylight savings time. Discussed how pipeline operators and shippers currently manage the different start of gas day times. Discussed the interaction between the start of gas day for pipelines and for producers and the implications for primary GTAs and GSAs. Start of gas day Recommend standard of gas day for East Coast pipelines to be the same time as per AEMC recommendation in the Final Determination for the National Gas Amendment (Gas day harmonisation) Rule 2017 as 0600 AEST. Western Australia to have standard start of gas day as 0800 AWST. Recommendation for Northern Territory pipelines to be harmonised with the East given pending connection. Gas specification Discussed the benefits in standardising the language for clauses where the content is essentially already standard. Commented broad wording can achieve standardisation and maintain flexibility. Gas specification Recommend the gas specification clause references the Australian Gas Specification standard as updated from time to time as the minimum and all applicable laws, with a reference to pipeline specifications if are specific technical requirements to limit the specification further on a pipeline. Gas quality Similar to ‘Gas specification’ all current standard contracts have similar clauses, and this the in principle recommendation. Discussed that the party responsible for odorisation can differ on different pipelines. GMRG – add to “parking lot” to revisit at a later stage: Recommend the gas quality clause includes: Gas supplied must be in accordance with the gas specification. Service provider can refuse to accept gas if it is off spec If the customer asks the service provide to accept off spec gas, the customer is responsible for all resulting loss. Each party must advise the other as soon as practicable
once they are aware of off spec gas. . The party responsible for odorisation is to be denoted via a check box for each pipeline. Further details yet to be discussed such as details of liabilities Metering Discussed the details included in the metering clause including: ownership, operation, maintenance, obligations, audit and correction, tolerance thresholds, calibration. Discussed the differences between allocation and metering. Discussed the obligation to provide the metering service should be with the pipeline operator, rather than the primary shipper. Discussed that a secondary shipper should have a right of recourse for inaccurate metering. Commented the baseline for the standard will be referenced to the Measurements Act. Discussed a preliminary approach to this term as: Ownership, operation and maintenance provisions for meters are accounted for in primary contracts and the responsibility for this service will not be required to be transferred in an operational contract to the purchaser of the secondary capacity contract. Audit and correction provisions can be standardised, including: Provision against pipeline operator Thresholds set by lowest common denominator Independent auditor Reasonable request (set by tolerance levels) The person in error pays Applicable period is yet to be determined, this may be included in Billing provisions. There may be technical details that can be further standardised in the secondary contract. Reference to a metering and measurement ‘manual’ of All - Research and understand detailed requirements for the metering and measurement clause to determine what details are required, which details can be standardised, and which need to be pipeline specific. GMRG – add to “parking lot” to revisit at a later stage: There may be an opportunity to improve allocation procedures, particularly where there are separate receipt and delivery meters at interconnection points between pipelines. If a single shipper has both a primary and a secondary operational contract with a pipeline operator, how the interaction between these contracts including aggregation and netting is to be managed.
