Shippers

Balancing Regime

  • Yes, traders also need to be informed about the balancing regime and needs to be able to receive and send all the related messages.
    Although, fundamentally, a trader will not experience imbalances quickly, it may be the case that an imbalance occurs between entry and exit in the portfolio, e.g. due to incorrect  portfolio management or an error in the nominations/confirmations with counterparties.

  • If you want to become an offeror on the gas exchange you must satisfy a number of requirements. Click here for the website of ICE Endex. If you can trade on the exchange of ICE Endex that is sufficient to offer flexibility to the gas exchange in the run-up to a balancing action. GTS does not propose any additional requirements.

  • In principle, your POS is never reset. Settlements having an effect on the POS are WDBA’s. It is only when a WDBA is performed that volumes are set off pro rata against the positions (POSs) of the causers. Shippers with a position opposite to the SBS at the time of the balancing action are not affected.

  • It is impossible to estimate in advance. We look 10 minutes and 15 minutes past the hour to the end of hour prediction of the SBS. If the prediction of the SBS at 10 minutes past the  hour gives a reason to a WDBA, then an announcement is made ​​in Gasport and a Request For Quote (RFQ) is placed on the trading screen of the ICE Endex. The announcement and the RFQ is an estimate of the volume and product placed on the within-day market of ICE Endex and is based on the latest information.

    If the prediction of the SBS at 15 minutes past the hour still gives a reason to a WDBA, then ​​an update of the announcement is made and again a Request For Quote (RFQ) is placed on the trading screen of ICE Endex.

    If the prediction of the SBS for the next hour at 21 minutes past the hour gives a reason for a WBDA than an order is placed on the within-day market of ICE Endex.

    The type of product for which the order is placed, is dependent on the color of the zone wherein the SBS is predicted. In the light green zone GTS send an order for a WD product to the exchange with a lead time of 2 hours and 40 minutes with supplies for the remaining hours of the gas day. As an indication, an order that leads to a transaction at 12:21 will be delivered from 16:00 to 06:00. In the orange and red zone GTS send an order for a Next-Hour product with a lead time of 40 minutes. The whole delivery takes place in one clock hour. An order for a Next Hour product that leads to a transaction at 12:21 has a delivery from 13:00 to 14:00.

  • We disclose the size of the zones per hour, based on the estimated transport load (with regard to the programmes delivered by the Shippers), at least two hours before the beginning of the gas day. These hourly values will not be changed after they have been published.

  • No, you are only obliged to apply damping if you transport gas to exit points that deliver to domestic consumers.

  • The volume that must be called will be calculated as follows:

    • Difference between the anticipated final value of the SBS and the boundary value of the dark green zone.
    • The part that possibly is not yet delivered of a realized WDBA transaction is included in the determination of the volume of any new WDBA. This only applies for WDBA with the SBS in the light green area.
    • If the SBS is in the light-green zone, and the imbalance is less than the unbalance of the previous hour, no WDBA will take place.
  • The accountable POS will, apart from in exceptional situations, indeed be published between xx:15 and xx:20. The reason for this is that the near real-time allocations of the CSS are only available at xx:13. This is because actual near real-time allocations are used for determining the accountable POS and not the allocation from a previous hour as was the case for the determining the forecast POS.

  • The accountable POS is indeed only available between xx:15 and xx:20.
    For a POS where no near real-time allocations are needed that are only available after 5 minutes past the hour (such as RNB/PNB,TTF-B, etc.), the prognosticated POS for xx:00 (which is available before xx:05) is equal to the accountable POS at xx:15 – xx:20.

  • Yes, multiple portfolios with multiple POSses. A POS is per portfolio.

  • No, GTS has only a prognosis value for the coming hour.

  • Yes, the POS is also determined for a wheeling portfolio and a WDBA may also apply.

  • The invoice is kept the same as the BidPriceLadder invoice as much as possible. The two changes are:

    • The Line Pack Flexibility Service is added
    • On the front page (PDF) the total of balancing actions (supplied en received) is mentioned in “Exchange”. In the attachment you can find per balancingaction if it concerns supplied or received.
  • Yes this is possible.

  • Yes, a separate download has been provided for the zones (which indicates zones for one or more gas days). It is correct that in the SBS download, this zone info only shows the applicable zone. The specs for the separate zone message are given under the message specifications on the website (GTS_InformationServices_R1).

  • Yes

  • For the Within Day Balancing Actions a message is displayed immediately when the prognosis is that an order on the exchange platform is required. This message will be displayed on all screens under the Dispatching menu item.

    The message that will be constructed has the following format:

    GTS WDM Order Forecast at: <xx:05>/<xx:10> LET - GTS <buys>/<sells>

    Product: <single hour>/<remainder of day>

    Amount per hour: <value> MW/h

    Total amount: <value> MWh

    SBS forecast value: <+/-value> MWh
