This Market Rules & Manuals Library (the “Legacy Library”) is one of two libraries containing documents needed to interact in Ontario's electricity marketplace.
PERIOD OF APPLICABILITY: The documents in this Legacy Library apply to, and are in force with respect to:
the period prior to a Market Transition, as that term is defined below, insofar as the included provisions are relevant and applicable to the rights, obligations, and authorities of the IESO and market participants relating to activity in the IESO administered markets prior to commencement of Market Transition; and
such other period following a Market Transition as may be provided for in the Market Rules and Manuals applicable to Ontario’s renewed electricity marketplace
The term “Market Transition” has the meaning ascribed to it in MR Ch.0.11 which may be found in the Renewed Library.
Both the Legacy Library and the Renewed Library contain:
Market Rules, approved by the IESO Board of Directors, which govern the IESO-controlled grid and IESO-administered markets; and
Market Manuals and procedures, approved by IESO management, and which provide more detailed descriptions of the requirements for various activities specified in the Market Rules, including the forms and agreements required by market participants.
Capacity Auction Rules Library
