Renewed Market Rules & Manuals Library

Renewed Market Rules & Manuals Library

This Market Rules & Manuals Library (the “Renewed Library”) is one of two libraries containing documents needed to interact in Ontario's electricity marketplace.

PERIOD OF APPLICABILITY: The documents in this Renewed Library apply to, and are in force with respect to:

  1. the period after the 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 following the commencement of Market Transition; and
  2. such other period prior to a Market Transition as may be provided for in the Market Rules and Manuals applicable to Ontario’s legacy electricity marketplace

Legacy Library

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

Capacity Auction Participants, including Demand Response Auction Participants, must consult the Point-in-time Rules applicable to the Capacity Auction or Demand Response Auction in which they participated, by date, for purposes related to their participation or to the satisfaction of program specific obligations. The Point-in-time Rules may differ in material respects from the current set of market documents posted below. 

See Capacity Auction Rules Library for applicable Point-in-time Rules for Capacity Auction Participants.
