Bilateral hub request management

The Operational Terms (Section 2.2.4 to 2.2.8) and OSD 0701 (section 16) establish requirements for Trading Parties to prioritise and manage Requests within the Bilateral Hub. In accordance with these provisions, all bespoke agreements between pairings must be recorded in writing using this template (also available via key documents - see 'System and assurance').

Where Trading Parties cannot agree bespoke arrangements for the prioritisation and management of Requests, the Normal Request Capacity shall apply.

The Normal Request Capacity is considered a fallback provision only. In the rare cases where it must be applied, Trading Parties shall follow the calculation set out in OSD 0701 (Section 16). The Normal Request Capacity multiplier for the purpose of this calculation is set as follows:

The Normal Request Capacity is applied weekly and only imposes a limit on Low Impacting Requests in the Bilateral Hub. For example, a multiplier of 0.01 applied between a Retailer and Wholesaler sharing 10,000 SPIDs at the start of Month A would permit 100 Requests to be submitted per week until the start of Month B (where the number of shared SPIDs is reassessed).

In this example, a Retailer could submit more than 100 High Impacting Requests in one week, however in doing so would be unable to submit any Low Impacting Requests in the same week. Had it submitted 80 High Impacting Requests in that week, there would be additional availability for 20 Low Impacting Requests.
