Market Rules & Manuals Library

The Market Rules & Manuals Library contains the documents needed to interact in Ontario's electricity marketplace.

The Market Rules, which are approved by the IESO Board of Directors, govern the IESO-controlled grid and IESO-administered markets.

Market manuals and procedures, approved by IESO management, provide more detailed descriptions of the requirements for various activities specified in the Market Rules, and include the forms and agreements required by market participants.

The current set of market documents known as Baseline 38.1, was updated and published on December 6, 2017.
