IESO Board approves market rule amendment

June 16, 2016

The IESO Board has approved a market rule amendment at its meeting on June 15 to explicitly allow the IESO to share confidential information in the form of a basecase directly to, or to a consultant of, a market participant, a connection applicant, or a person planning on constructing or modifying a facility for the purposes of completing reliability based power system studies. In addition, the amendment eliminates the requirement for the IESO to advise every market participant affected by the disclosure of confidential information to an Ontario transmitter where such disclosure is required for transmitters to manage, operate and maintain their transmission system in a safe and reliable manner or for the reconciliation of applicable transmission service charges. The effective date of this amendment is July 8, 2016.
