Summary

The current Gas Demand Side Response (DSR) framework has been in place since 2016 and the DSR market has only opened once since then, which was during Beast from the East in 2018. Zero bids were placed onto the DSR Market within the OCM.

As part of our winter preparedness activities, we have reviewed the current DSR framework and engaged with our customers and stakeholders to understand the reasons for the lack of participation and if there are any reforms that could be made which would make the make the scheme more attractive.

In order to have a guaranteed level of response, we are proposing to hold an Invitation to Offer process where shippers will be invited to post DSR offers and if they are accepted, Shippers will receive an “Option” payment. The receipt of the Option Payment obligates Shippers to post an offer on to the DSR market in the event of it opening following either the issuing of a Gas Balancing Notification (GBN) or a Margins Notice (MN) at D-1.

Therefore, we are proposing the following reforms:

  • Introduction of an “Option” or Availability payment
  • Introduction of additional penalty charges for Shippers who do not post bids onto the DSR market in accordance with the “business rules” as per UNC modification 0822
