Market Rules and Market Design
Technical Panel Requests Comments on Replacing PKI Digital Certificates

The Technical Panel has requested that rule amendment MR-00376: Market Administration - Replacing PKI Digital Certificates be published for stakeholder comment (http://www.ieso.ca/imoweb/pubs/mr2010/MR-00376-R00.pdf).
The proposed amendment specifies market participant and IESO accountabilities related to communications and transactions sent using IESO software. It is proposed that key provisions of the current Certificate Subscriber Agreement (CSA) (http://www.ieso.ca/imoweb/pubs/marketEntry/me_CertSubAgreement.pdf) be incorporated into the market rules. This will replace the CSA, which will be terminated by the end of 2011 when PKI digital certificates are phased out.

Comments can be submitted by January 13, 2011, using the written submission form:
