IESO EIM Portal Refresh

In the Real Time Production Build for IESO, the Energy Market Interface (EMI) and eMIM Web Service planned for the September 16, 2021 R46.0 Release has been deferred and will be rescheduled to a later date. According to IESO, the EMI site and eMIM Web Service will function as normal using the existing Portal AD accounts and NOT the new IESO Gateway system accounts. which was originally scheduled to be pushed into production has been deferred and will be rescheduled to a later date.

As part of the EIM portal refresh project, the IESO plans to migrate from the current Oracle Access Manager and internal Microsoft Active Directory authentication solution to the Okta cloud-based solution (IESO Gateway). TRA, EMI, Dispatch, CROW (OCSS), Online IESO, Prudential Manager, Reports Site, CRS GUI and FUS applications will all need to be switched over to IESO Gateway in Sandbox and Production Environments. Manual account provisioning for external users in Online IESO will be updated to automated account provisioning. In addition to what was previously communicated, Online IESO API’s will also be updated.

As communicated by IESO, the reasoning behind the delay is that due to the number of scheduled changes for September 16th release, some application cutovers have exceeded their expected window for completion. As a result of this, the cutover for EMI and eMIM Web Service are deferred to a later date (to be scheduled) to ensure its success.

External users that interact with the Energy Market Interface (EMI) and eMIM Web Service (in person or through automation) are requested to continue using their existing Portal Active Directory accounts and not use the new IESO Gateway accounts. The URL for the Energy Market Interface (EMI) and eMIM Web Service are to remain the same.
