4 ebix Business Requirements for Change of Supplier 4 A. About this document This document is a business requirements specification for the Change of Supplier process within the structuring process of the European energy market. The processes related to Change of Supplier are a centrepiece of the Structuring process, hence these processes are based on the document A Regional Reference Model for the Change of Supplier Process [7] made in a common project between Eurelectric and ebix. However, to be in line with the Harmonised Role Model from ENTSO- E, ebix and EFET, the naming of the actors have been accordingly changed [2]. As a general introduction ebix has published a separate document Introduction to ebix Business Requirements and Business Information Models [3]. The introduction also includes the generic model elements that are not specific for a particular business process. In line with UN/CEFACT Modelling Methodology version 2 (UMM-2) ebix defines the business requirements before starting the actual modelling. These requirements have been specified by the ebix work group Customer Switching (CuS) and are the basis for the Business Information Model, which is published, in a separate document. The Business Information Model is in turn the basis for the creation of XML schema s and is expected to be the basis for the specification of web services in a next version of the model document. Since ebix supports both EDIFACT and XML the model will also serve as the basis for the creation of Message Implementation Guides for the mapping to EDIFACT UNSM s. The Business Information Model and the syntax specific structures are specified by the ebix Technical Committee (ETC). A.1.

Change of Supplier (Business Process UseCase) Description UseCase description: Change of Supplier Figure 1 Change of Supplier definition beginswhen precondition endswhen postcondition This is the process where a New Balance Supplier (together with the Balance Responsible Party) will be registered in the Metering Point register as the New Supplier for the Metering Point. The Metering Point Administrator makes all necessary updates for the Change of Supplier, including distribution of master data for alignment of the business partner databases. When a Customer asks for a contract with the New Balance Supplier and the Change of Supplier process is initiated The New Balance Supplier has all needed information to be able to request Change of Supplier When the Request Change of Supplier is confirmed or rejected, and if confirmed then all relevant parties are informed about the Change of Supplier and master data of the Metering Point involved have been distributed to relevant parties. The Customer has changed Balance Supplier and all involved parties have exchanged and synchronised their master data, including determination and exchange of the meter read related to the Change of Supplier.

9 ebix Business Requirements for Change of Supplier 9 definition In this process, a contract is made for supply to the Customer and the New Balance Supplier identifies the Customer data (invoicing data) e.g. name, address, and the Metering Point involved. The New Balance Supplier verifies and collects needed information to run the Change of Supplier process. beginswhen precondition endswhen postcondition exceptions When the Customer and Balance Supplier make a supply contract. The Customer has the intention to make a contract with the New Balance Supplier. When all requisites for making the supply contract are fulfilled. The Customer has a contract with the New Balance Supplier and the New Balance Supplier has the needed information to Request Change of Supplier. The Customer may make an additional contract for a fixed amount of energy with a different supplier. This however does not affect the Change of Supplier process and requires a separate agreement between the Supplier of the fixed amount and the Supplier of balance energy. This alternative scenario is usually applied by large Customers only and is not further detailed in this model. actions See Based on national rules, pre-change checking and verification of contractual matters between the New and the Old (current) Balance Supplier are currently done in several of the countries participating in ebix.

11 ebix Business Requirements for Change of Supplier Verify existence of Grid contract Figure 5 Verify existence of Grid contract Description UseCase description: Verify existence of Grid contract definition beginswhen In this process, the New Balance Supplier verifies if there is a grid access contract in effect for the Metering Point he is intending to supply to, by sending a request to the Grid Access Provider to get the Grid access contract details. When the New Balance Supplier intends to settle a contract for energy supply at a Metering Point. precondition Metering Point ID is known National rules require the verification Unknown Grid access contract condition endswhen postcondition exceptions When the New Balance Supplier obtained sufficient information to verify the existence of a grid contract The existence of a grid access contract is verified to the New Balance Supplier None actions See

12 ebix Business Requirements for Change of Supplier Business Process Figure 6 Verify existence of Grid contract Note that there are no documents specified by ebix for this business process. The documents related to this process should be made nationally Verify potential obstructing elements (Business Process UseCase) The process Verify potential obstructing elements is implemented in different ways in different countries, involving different business partners. In some countries, this process is defined as a process between the Old and the New Balance Supplier. The process, if used, must be defined on a national level Determine Meter Read for Change of Supplier In this process, the New Balance Supplier will agree with the Customer to obtain an upfront meter reading and pass it to the Metered Data Responsible, for use in the Determine Meter Read for Change of Supplier process.

13 ebix Business Requirements for Change of Supplier Identify and obtain critical Change of Supplier information (Business Process UseCase) Figure 7 Identify and obtain critical Change of Supplier information Description UseCase description: Identify and obtain critical Change of Supplier information definition beginswhen In this process, the New Balance Supplier will identify and obtain the necessary Change of Supplierinformation of the Metering Point. Examples of data that may be identified and obtained: Identification of the Metering Point Metering Point responsible party Proposed change date Consumption data, e.g. estimated annual consumption and load profile. Location data, e.g. Metering Point address Metering method When settling a new supply contract. The New Balance Supplier will need to identify and obtain critical Change of Supplier information precondition The Metering Point ID is available Required by national rules endswhen When the critical information is obtained by the New Balance Supplier postcondition exceptions The critical information is obtained None actions See

The documents related to this process should be made nationally Request Metering Point Characteristics (Business Process UseCase) The process area Request Metering Point characteristics is documented in a separate document, see [8].

15 ebix Business Requirements for Change of Supplier Request Change of Supplier (Business Process UseCase) Description UseCase description: Request Change of Supplier Figure 9 Request Change of Supplier definition beginswhen In this process, the New Balance Supplier will request Change of Supplier at a Metering Point and the Metering Point Administrator confirms or rejects it. During the business process, the change is confirmed and the Metering Point register will be updated, or the change is rejected. When the New Balance Supplier decides to send a request for Change of Supplier to the Metering Point Administrator, in order to achieve the intended start of supply date for the new supply contract. precondition A supply contract is in place A start of supply date has been agreed with the Customer. The requirements from Make supply contract and Identify and obtain critical Change of Supplier information have been fulfilled. endswhen postcondition exceptions When the Request Change of Supplier is confirmed or rejected. The Change of Supplier process has been confirmed or rejected by the Metering Point Administrator to the Balance Supplier. Based on national rules; in case of missing upfront meter reading the Change of Supplier may be cancelled. actions See

In this document, the Linked parties are specified Determine Meter Read The Process area Determine Meter Read is documented in the ebix model Measure [5] Varieties of Change of Supplier processes The variants described in this chapter reflect examples of specialities that the CuS project currently have not looked into in detail, which may not be completely covered by the description above.

19 ebix Business Requirements for Change of Supplier Bulk Change of Supplier Bulk Change of Supplier is the process of changing all, or a block of, Customers belonging to one Balance Supplier. Bulk Change of Supplier may be related to bankruptcy of a Balance Supplier or a Change of Supplier of all Metering Points related to one Customer, such as petrol stations, banks etc. Bulk Change of Supplier is possible in several of the countries participating in ebix, i.e.: In the Netherlands all Customers belonging to one Balance Supplier may be changed using a manual trigger of the process (manual handling of the 392 information), but using normal messages for the confirmations/notifications (both to the Balance Supplier and the Balance Responsible Party. In Norway Bulk Change of Supplier is done using (repeatedly) normal Change of Supplier messages Change to/from Supplier of last resort A Supplier of last resort is a Balance Supplier appointed by the authorities (e.g. the regulator) to supply energy under certain conditions to Customers rejected by other Balance Suppliers. Change to/from Supplier of last resort is possible in several of the countries participating in ebix, i.e.: In Norway, the Grid company acts as the Supplier of last resort. Belgium, Denmark and Germany have special processes for Change to/from Supplier of last resort Change to/from Default Supplier A Default Supplier is a Balance Supplier that supplies Metering Points within a Metering Grid Area (chosen by the Metering Point Administrator) when the Customer has no Balance Supplier. Normal Change of Supplier messages can be used for changing to/from the Default Supplier. This process exists in Sweden, Germany and Denmark, but is not possible in Austria, Norway, Netherlands and Belgium.

21 ebix Business Requirements for Change of Supplier Business Entity View Short introduction In these business requirements the ebix work group CuS has for the first time used the principle of specifying the core data set as business requirements. This core data set is defined as the set of information that is required when using synchronous web services as the exchange mechanism. The information required for a-synchronous web services is added as an option. Finally, optional information is specified. For exchange as a stand-alone document, header and context information will have to be added. But this is not regarded as a business requirement when defining the core data set, but as a requirement for technical implementation or mapping to syntax. It is important to note that it is assumed for defining the core data set, that Metering Points are uniquely dedicated to either electricity or to gas. Consequently, the specification of the business sector is not part of core data set anymore.
