Market Renewal Program (MRP) - Pre-Production Connectivity Testing Plan (External) - Version 1.0

Sep 12, 2026

Uploaded by Miles

Market Renewal Program (MRP) pre-production connectivity testing plan explains how external market participants prepare to validate access to new and updated IESO market-facing systems ahead of the May 1, 2025 go-live. It defines testing scope limited to connectivity for EMI, MIM via API/MTW, and Dispatch via GUI and web services, while excluding specified IESO applications and bid/offer and dispatch interaction. The plan provides schedules, test-case access and result submission guidance, reporting and re-execution handling, and participation roles support.

Introduction To ensure that external stakeholders are ready for MRP Go-Live on May 1, 2025, the IESO has provided Market Participants (MPs) extensive opportunities to become familiar with the changes being made to the tools and interfaces that are changing because of MRP, to help identify any defects within the IESO’s systems, and to provide Market Participants confidence that their systems can interact with IESO’s market-facing applications prior to the new and updated systems being implemented next year. In response to feedback received from stakeholders on MRP’s testing approach, the IESO will be offering two additional testing activities for Market Participants to verify that they can smoothly transition to the new Production systems : Pre-Production Connectivity Testing and Cutover Testing. This test plan is focused on Pre-Production Connectivity Testing. The purpose of this document is to: • provide an overview of what Pre-Production Connectivity Testing is, • provide guidance on how Market Participants can prepare for Pre-Production Connectivity Testing, • outline key dates and information that Market Participants will need to be aware of to complete their testing activities on time, and • identify who Market Participants can contact to receive testing support during this period. 2. Pre-Production Connectivity Testing Phase The objective of Pre-Production Connectivity Testing is to ensure that Market Participants can access the new and updated market facing systems and address connectivity issues prior to the cutover to the Production environment starting on April 30, 2025. If Market Participants are interested in participating in Cutover Testing that is scheduled to run from March 31, 2025 to April 2, 2025, Market Participants must participate in Pre-Production Connectivity Testing. The Pre-Production Connectivity Test Phase will span two (2) weeks and is scheduled to start on March 17, 2025 and end on March 28, 2025. 2.1 What is in scope for Pre-Production Connectivity Testing? Market Participants will only be testing their access and connectivity to the following applications: • Energy Market Interface (EMI), • Market Information Management (MIM) System via the API Tool and the MIM Web Services Toolkit (MWT) , • Dispatch Service via the graphical user interface (GUI), and • Dispatch Service via web services 2.2 What is out of scope for Pre-Production Connectivity Testing? The following applications will be out of scope for Pre-Production Connectivity Testing: • Online IESO, • Outage Coordination and Scheduling System (OCSS), and

FAQs

What is the goal of Pre-Production Connectivity Testing for external stakeholders?

To ensure market participants can access new and updated IESO market-facing systems and address connectivity issues before cutover to the Production environment.

Which applications are included or excluded in the Pre-Production Connectivity Testing scope?

In scope are EMI, MIM via the API Tool and MIM Web Services Toolkit, and Dispatch service via GUI and web services. Out of scope are Online IESO, OCSS, and the IESO Report Site, and participants do not perform bid/offer submission or dispatch message processing during the test.

When does Pre-Production Connectivity Testing run and what happens if participants want to join Cutover Testing?

The two-week phase is scheduled from March 17, 2025 to March 28, 2025. To participate in Cutover Testing (March 31, 2025 to April 2, 2025), market participants must participate in Pre-Production Connectivity Testing.
