Latest update On 22 June 2022 the Change Board voted to approve this modification under Self-Governance. This modification will be implemented on 3 November 2022 (November 2022 SEC Release).

What is the issue?

In the Smart Energy Code (SEC), Appendix AA ‘Threshold Anomaly Detection Procedures’ currently requires the Anomaly Detection Threshold (ADT) File and Exit Quarantine files to be provided to the Data Communications Company (DCC) by email. DCC is of the opinion that it would be a more secure process to provide this information via SharePoint. It is believed the current method is insecure and poses potential security risk as email is not considered a secure delivery method. This is due to it lacking end to end encryption and being potentially susceptible to Security breaches through either deliberate malicious activity or erroneous activity.
To mitigate the potential security risk posed by email, the DCC have proposed to change the wording of SEC Appendix AA from “Email” to “DCC’s preferred secure delivery method of choice”. The DCC’s current secure delivery method of choice would be via DCC SharePoint.

What is the solution?

The Proposed Solution is to replace the main delivery method of emails with SharePoint.
