Genstar4 Transaction Notifier

The Genstar4 Transaction Notifier module covers the mandatory requirements for supplying bilateral contract volumes and meter volume reallocations to the Energy Contract Volume Aggregation Agent (ECVAA) and interactions with the Central Registration Agent (CRA) and Central Data Collection Agent (CDCA).

Position Monitor provides assurance that the notified contract position is consistent with that held by Elexon.

Key functional areas include:

• Full support for CVA Qualification and the receipt of data flows from the CRA and CDCA covering registration, maintenance and metering data flows.
• Compilation of Energy Contract Volume Notification Agent Authorisations (ECVNAAs) and their submission to the central market agent (ECVAA).
• Equivalent functionality for Metered Volume Reallocation Notification Agent Authorisations (MVRNAAs) is also supported.
• Automatic upload of the ECVNAA-Key or MVRNAA-Key from the ECVAA’s response, where the system party is the notification agent.
• Maintenance of Contract Groups for net ECV notification, the assignment of ECVNAA Id, and setting the ECVN-Reference (fixed for Overwrite, prefix for Additive). Individual contract volumes are allocated into these groups for net notification;
• Compilation and notification of Energy Contract Volumes (ECVNs) to the ECVAA. Both ‘Additive’ and ‘Overwrite’ notification methods are supported for the Net volume of a Group/ECVN Reference.

Contract volumetric profiles can be entered manually, loaded from an API or a CSV file, which can either be selected manually or auto-loaded from a monitored folder. Contract shapes can also be saved to and retrieved from a profile library.

Similar compilation functionality is provided for MVRNs, assigning fixed volume and percentage allocation for BMUs.

A comprehensive set of reports and graphs is provided covering the following areas:

• Contract volumes and the status of notifications, net Counterparty and Energy Account graphs;
• Tracking log of the contract volume notifications;
• Display of daily reports from the ECVAA of authorisations, contract volume and meter reallocation notifications, rejected notifications, credit limit warnings and the current indebtedness level;
• Display of ECV and MVR Notification Acceptance and Forward Contract reports from the ECVAA of notifications for within day and for the next seven days respectively.

Position Monitor

Position Monitor provides checking and visualisation of the notified position recorded in Genstar4 with that reported by the ECVAA, and identifies any discrepancies.

• Each Forward Contract report (ECVAA-I022) is compared to the notifications stored in Transaction Notifier and discrepancies are notified to the user in a set of Forward Contract Report (FCR) screens.
• An equivalent set of Position Monitor (PM) screens display the most up-to-date picture of the central-market position by updating the last FCR data with any subsequent Acceptance Feedback reports (ECVAA-I028);
• Both FCR and PM comparisons are displayed in two formats: a set of hierarchical screens which allow the user to drill down from overall daily totals to individual notifications and periods, and a matrix style layout which displays all notification periods in an overall grid.
• A template Rejection Notice can be produced for notifications which do not reconcile, to facilitate the dispute process.

Forward Contract Report Checking

Genstar4 ECVAA interface

The interface to the ECVAA and other Elexon agents is provided by a common central-market agent interface, which handles the file exchange format protocols: Sequencing and checksum validation, file format validation, interaction with the third-party ‘Xsec’ encryption-decryption package, and the production and receipt of acknowledgements.
