The OEB has issued a letter proposing to implement a requirement for utilities to report cyber security incidents to the IESO, which will then report the most impactive incidents to the OEB. The IESO will use the reported information to distribute de-identified situational awareness alerts to the industry. OEB staff looks forward to the opportunity to present this initiative and engage with industry participants at an upcoming CSAC meeting. All licensed electricity transmitters and distributors are encouraged to participate.
