Final Release Plan for IESO systems now available

July 16, 2015

The final Release Plan for changes to IESO IT Systems, Release 34.0, is now available.

Phase 2 of the IESO Reports Site for confidential reports will be made available to participants as of July 31, 2015. The new Reports Site will run in parallel with the existing Reports Site until early 2016 to allow participants to transition. Public reports are not affected by this project.

The deployment of the new Meter Data Distribution (MDD) solution is included in this release. MDD will replace the existing MV-WEB system through the Portal. With MDD, metering information will now be available on the new IESO Reports Site only.

The "Online Settlement Form changes to submit Biomass Non-Utility Generation (NUG) and Energy from Waste (EFW) facility data and the number of Class A customers" is included in the release as announced in the Target Release Plan. This will be made available to participants for the September settlements submission period.

"Online IESO – Register facility and equipment data," has been postponed and will be included in a future release.

The full release calendar is found at IT Release Schedule. Comments may be sent to
