The OEB has issued a Notice of Proposal to Amend the Distribution System Code and Transmission System Code. The amendments require utilities to comply with a new Ontario Cyber Security Standard document with an initial focus on privacy, corporate governance, and situational awareness related to cyber security. We invite stakeholders to provide feedback to the proposal by March 5, 2024. The OEB is also making changes to improve the effectiveness of utilities’ cyber security reporting. These revisions align reporting questions with the Ontario Cyber Security Framework (OCSF), increase the granularity of response options, and enable utilities to report against version 1.1 of the OCSF, released in December 2023.
