Baseline Calendar

As the IESO systems and processes evolve and mature, market documentation will be updated. Market documentation consists of Market Rules, market manuals, technical interface documents and other related documents. These documents are changed to reflect Market Rule amendments approved by the IESO Board, revised procedures, updated tools and new information.

The current set of market documentation forms the market documentation baseline. At regular intervals, a new baseline will be issued. In advance of these baseline dates, the IESO publishes proposed changes to the market documentation to allow market participants to comment on the impact that these changes will have on their processes and systems. Market Rule amendments under development or approved are posted on an ongoing basis on the Current Market Rule Amendment page. Approved Market Rule amendments along with proposed changes to technical interface documents, market manuals and other documents can be found on the Pending Changes page.

The calendar below outlines the proposed timelines for baselines. As these dates approach, they will be confirmed by the IESO through announcements to Market Participants. It should be noted that Technical Interface documentation is available for comment earlier than changes to the market manuals and related documents. The Baseline Calendar dates are related to the dates on the Pending Market System Software Changes Release Calendar.

On certain occasions, changes to market documentation will be made as updates to the current baseline to accommodate urgent rule amendments, systems changes or IESO procedural changes. These changes will be made on dates other than shown below and will be communicated to Market Participants with as much advance warning as possible.
