Meter Data Management System Replacement
September 12, 2024
The IESO is launching a project to replace the current Meter Data Management System (MDMS), as the current vendor will no longer be providing software upgrades. The MDMS is the software system that collects, validates, stores and processes meter data to support the IESO’s metering and settlement processes as outlined in the market rules and market manuals.
This initiative is important for maintaining reliable settlement services in a way that will have minimal impact on external stakeholders. To stay informed on how the progress, please visit the IESO’s website.
