Gas Bulletin Board Frequency Asked Questions - Last Updated 18 October 2018
Registrations and Exemptions
Q. What exemptions are there?
A. A BB participant may be granted an exemption on providing information, relating to a BB facility, where that information will be provided by another person. The most common example of this is where two pipelines intersect and one of the BB participants will provide the information and the other BB participant will apply for an exemption. All other information, required to be submitted under the Rules, still needs to be submitted by the participant holding the exemption.
The participant applying for the exemption must provide supporting evidence from the other participant endorsing the exemption and acknowledging that they will take on the function of BB reporting entity for the information for both facilities. AEMO may seek further evidence to confirm that the exemption can be granted.
Q. What facilities can get an exemption?
A. There are no facility exemptions in the new Rules.
Q. I have a new facility, or a facility that was subject to an exemption prior to 30 September 2018, when do I start submitting data?
A. AEMO will be contacting participants in the first week of October for any facility that is new to submitting data and will be requesting further information (for facilities that AEMO does not have the necessary information) or setting an effective date for submissions to commence. This date is likely to be late October, or earlier by agreement.
Q. When will I know if I have an exemption on providing data?
A. AEMO will begin assessing exemptions in the first week of October and will be requesting further information, or granting exemptions, within 20 business days. Participants are obliged to provide information until the exemption is granted.
Q. In what cases do the pipelines connected to a production facility need to be separately registered as BB pipelines?
A. Factors that AEMO will consider in determining whether a pipeline which is connected to a production facility, must be registered as a BB pipeline include:
- Definition of a pipeline in the National Gas Law which states that the definition does not include
- anything upstream of a prescribed exit flange on a pipeline conveying natural gas from a prescribed gas processing plant; or
- if a connection point upstream of an exit flange on such a pipeline is prescribed, anything upstream of that point; or
- a gathering system operated as part of an upstream producing operation
- The definition of lateral gathering pipeline in Part 18 of the National Gas Rules further goes on to describe a lateral gathering pipeline as a pipeline:
- operated as part of an upstream producing operation; and
- used principally to transport natural gas for injection into a BB facility operated as part of the upstream producing operation where that BB facility is not itself a lateral gathering pipeline
- AEMO is satisfied in its discretion that the information relating to that BB facility is not material having regard to the purpose of the Bulletin Board, taking into consideration the definitions listed above.
Q. I have forgotten my FTP password, where can I go to regain access?

Q. The Rules require nominations and forecasts for up to six days into the future, but I don’t receive nominations from my shippers this far in advance, what do I submit?
A. Any quantity notified by BB shippers to the relevant facility operator, up to D+6, must be made available to the GBB. If you have any nominations beyond D+1 then this information must be provided. Further information clarifying this is specified under rule 185(1)(b) “Forecasts for Nominations”. If you are submitting less than D+6 this may flag in the AEMO systems as a potential non-compliance. Participants should notify AEMO of any general business practices that may impact on the ability to comply with this requirement.
Q. What constitutes a material change in connection point data regarding nominations?
A. A material change is defined in the Rules as in respect of information about nominated or forecast use of a service provided by means of a BB facility, a change to the nomination or forecast that exceeds the greater of 10% of the nameplate rating of the BB facility and 30 TJ.
Further information clarifying this is specified in Section 7.5.2(f) of the BB Procedure:
(i) If there is a material change to the Delivery and Receipt Nominations or Forecast Deliveries and Receipts for a specific delivery point or a receipt point (as applicable); or
(ii) the changes to Delivery and Receipt Nominations or Forecast Deliveries and Receipts for all delivery points or receipt points for a BB pipeline for a gas day aggregate to a number that meets the material change threshold, the BB reporting entity must provide the updated information on that gas day.
Note: For aggregation in this provision, any change to volumes will always be deemed to be a positive number irrespective whether the gas flow is a delivery or receipt, or whether the volume has increased or decreased. A change to a receipt point or delivery point will always increase the aggregate and therefore increase the likelihood that the threshold for material change will be met.
Q. What do I submit if my meter data, for daily flow data, is not available by the submission cut-off time?
A. An estimate of the data should be submitted, with quality flag “OK”. This data must be updated when better quality information is available.
Q. In the nameplate capacity file, if the quantity doesn’t change are we still required to submit a capacity description? Can this be a default description?
A. This can be a default description as nameplate capacity is carried over from day to day. You will only need to change the description once a material change has either increased or decreased the standing capacity of the facility.
Q. Can I submit capacity for multiple sections of a pipeline?
A. This is possible and would give good insight into which section of the pipeline is experiencing reduced capacity. The choice of this split, if any, is at participant discretion.
Q. Do all pipeline receipt and delivery connection points need to be reported in the new ‘Nominations and Forecast’ file?
A. Yes. Each point much be submitted against for both actual, nominations and forecasts. The only connection points that are exempt from submitting are those associated with GPG units.
Q. In cases where Production Facilities receipt on to 2 different pipelines in the same day is it mandatory to report multiple receipt or whether only one value for the total field production is required?
A. For production facilities, only one aggregated number is required for daily submissions.
Q. What time zone are submission cut offs in, EST, EDST, local time or something else?
A. All submission cut off times are EST, ie. exclusive of daylight saving time
Q. In the short-term capacity outlook report, what is the Receipt Location and Delivery Location meant to be?
A. A receipt point is at one end of a facility and a delivery point is on the other end of a facility.
Q. Is there a way to work out what the differences are between the old GBB and new GBB report data?
A. We have published a document on the GBB website which helps explain the difference between the old and new GBB terminology. You can find that document here
There is also a spreadsheet also maps old connection point ID’s to their new ID so you can reconstruct comparable actual flows you can find here
The BB Aggregation Methodology may also assist in your understand which can be found here
Q. How do I know what I'm looking at is a full set of facility data for a gas day?
A. As the cutoff time for actual data submission is 1pm EST, data may be incomplete before that time. It is a rule requirement that a full set of data for a facility must be submitted by that time.
Q. What is a Facility Operator Group?
A. If there is more than one owner, operator or controller for a BB facility each of these is a facility operator and is taken to be a member of a facility operator group for that BB facility. All members of the facility operator group must apply to register and will nominate one of the members to be the responsible facility operator (i.e. the BB reporting entity).
Q. Why don’t all facilities appear on the Bulletin Board?
A. There are several facilities that are not required to register on the Bulletin Board because of either being a remote BB facility, a lateral gathering pipeline, or due to not meeting the applicable reporting threshold. A list of these facilities that AEMO is aware of is published under 'Notices -> BB Notices' on the GBB.
