Stage: 1 (Enquiry) Status: In Progress Date commenced: 2 June 2014

As part of its function to monitor the FTR market, the Authority recently enhanced its vSPD FTR rental tool to accommodate three additional FTR hubs, bringing the total number of hubs to five. During the testing phase of this initiative, the simulated results were compared with the actual historical results generated by the FTR manager. These tests revealed that the results produced by the vSPD FTR rental tool were different from those published by the FTR manager.

An enquiry was undertaken. The FTR manager also investigated and agrees with the Authority’s assessment. The FTR manager has initiated two change requests to correct the discrepancies. The impact the discrepancies was potentially substantive, although to date the actual errors in the calculation of FTR rentals have been immaterial.

There remains one minor issue that the Authority will verify once the change requests have been implemented and tested by the FTR manager.
