Changes to Reliability Assessments Information Requirements - Market Manual 2.8 (SE-99)

The IESO is proposing changes to the 10-year data submissions by Market Participants in accordance with Market Manual 2.8: Reliability Assessments Information Requirements.

Currently, Transmitters, Generators and Connection Applicants are required to submit reliability-related information covering a 10-year period due October 1 each year (via Forms 1223 and 1494). This information is used by the IESO to conduct security and adequacy assessments throughout the year – including assessments for NERC and NPCC.

In order to utilize and incorporate the most current data into these reports, the IESO would like market participants to consider any impacts that moving the October 1 due date to March 1 of each year would have on their business processes.

In addition, the IESO proposes the removal of Wholesale Consumers and Distributors from this Market Manual as they have not been required to provide reliability assessment information in previous years and it is not expected that it will be required in the future.

A short survey has been created to assist in providing feedback directly.
