Modification 0866 has been raised to introduce further enhancements to Gas DSR arrangements for daily metered consumers following experience of recent reforms and based on consumer feedback.

The Modification proposes that DSR arrangements for daily metered Consumers will be reformed in the following areas:

  • The timings and content of the DSR Options procurement tender process.
  • How the process of exercise of a DSR Option works, including how the ‘starting point’ for demand reduction is determined.
  • Enable Class 2 Consumers to contract directly with NGT for DSR Options; and
  • Amend the credit rules for Consumer DSR.

This proposal has the potential to increase the level of participation in the gas DSR Options process. This in turn will further enhance the suite of pre-emergency tools NGT can call upon in the event of a forecast supply shortage.
