The effective date for MR-00381-R03: Floor Prices for Variable and Nuclear Generation is February 1, 2013. Pursuant to the rule, the Board established the floor price for energy offers from flexible nuclear generation at -$5.00/MWh. The floor price for energy offers for variable generation will be established as part of the stakeholder consultation for the six-month review of the floor price for flexible nuclear generation.
The other four recommended market rules are currently anticipated to be effective in the third or fourth quarter of 2013, with the date to be specified by the IESO in a notice to all market participants. The above market rule amendment proposals are based on stakeholder consultations through SE-91 Renewable Integration, which includes the Dispatch Technical Working Group (DTWG) and the Floor Price Focus Group (FPFG).
