We hold an annual Tender event which is launched no later than 31st August where we invite Shippers and eligible Consumers to tender to offer DSR for the forthcoming Winter Period (Nov-Apr), they can also tender in for multi year DSR for a total of three Winter Periods.
By providing DSR prior to entering a gas supply emergency, DM consumers have the potential to protect their most critical loads by turning down and receive compensation for doing so. This has the potential to minimise the cost of demand interruptions and may reduce the likelihood of entering into an emergency situation where Firm Load Shedding could be enforced.
We have developed a DSR Guidance Brochure to help consolidate information on gas DSR in one place and provide a useful guide for anyone new to the scheme.
Operational Guidance Material – Demand Side Response
We have developed, with industry input, a Gas Demand Side Response Methodology setting out the framework for the DSR service. In July 2015 we held a two-phase trial and, based on the trial's success, Ofgem directed us to move to implementation. At least every two years the Gas DSR Methodology is consulted on, and then a report is published detailing the outputs of this consultation.

Product Description and Eligibility
Only a registered user at the supply points that comply with the eligibility rules specified in this DSR framework and methodology may enter offers into the DSR mechanism. In turn, the DSR framework and methodology must satisfy the criteria and obligations set out in the Gas Transmission Licence Special Condition 9.22.
There are currently three different DSR products which are designed to allow DSR participants to deliver a reduction with varying lead times. The products have been outlined below:
Within Day (D) – a reduction which is delivered within day and has a “tick down” feature so that I can be appropriately scaled depending on the number of hours left in the gas day.
Day Ahead (D-1) – a reduction which is delivered for the whole gas day (05:00 – 05:00) if exercised before 17:00 on D-1
5 Day Lead Time (D-5) – a reduction which is delivered for the whole gas day (05:00 – 05:00) if exercised before 17:00 on D-5
Both Consumers and Shippers can contract with NGT for DSR and participate with all three products. For DSR where the Shipper is the contracting party, the consumer who is delivering the demand reduction must daily read.
Each April, we publish a report on the number of Gas DSR offers and trades that have been placed on the On-the-day Commodity Market (OCM) over the previous winter.
