Proposed solution summary
  1. As an Electricity Consumer, I want the migration of my MPAN to the new HH Settlement arrangements to be as smooth as possible, so that the service I receive from my Electricity Supplier or it’s appointed agents is not interrupted As an Electricity Consumer, I want my ability to switch to be impacted as little as possible by MHHS migration activities
  2. As the Switching Operator, I want to be prepared for the increased volumes expected during the MHHS Migration Period. As the ERDS Provider, I want the CSS to be able to manage the volume of messages being sent so that I can provide the service I am required to during the MHHS Migration Period
  3. As an Electricity Supplier, I want the MPANs I select to the new HH Settlement arrangements to complete their migration without undue delay, so that the service I provide to Consumers is impacted as little as possible and so that I can meet my migration obligations As a MEM, as part of migration I want my new appointment and my legacy de-appointment to occur within the planned timescales so that the services I provide are impacted as little as possible As a Data Service, as part of migration, I want my new appointment to occur within the planned timescales so that the services I provide can commence in a timely manner As a Data Collector, I want my legacy de-appointment to occur within the planned timescales so that I have a clear understanding and smooth ending to the service I provide

Problem Statement
As part of the MHHS programme, it is necessary to migrate approximately 31 million MPANs from the existing settlement arrangements to those under the MHHS Target Operating Model. This will create a significantly increased volume of messages, whether for Switches or changes to Supplier Agents, for the CSS during the MHHS Migration Period. The CSS Service Definition does not currently require the Switching Operator to be capable of processing these additional volumes.

Proposed solution summary
  1. As a Consumer, where I have entered a bi-lateral NExA with the relevant Transporter, I want my Shipper and Transporter to have access to all the data they need when capacity referrals to the Gas Transporters are required.
  2. As a Gas Transporter, I want the details of the NExA to be held in GES, to increase visibility of the existence of the NExA and to provide details of the offtake parameters.
  3. As a Gas Shipper, I need to understand both that a NExA exists, and that I have visibility of the offtake parameters relative to the site, so that I can ensure that I take the necessary actions to ensure the Consumer has the appropriate booked Supply Point Capacity.
