Reserve Capacity - Special Price Arrangements

There are two mechanisms that may result in the establishment of Special Price Arrangements. 

The first mechanism results from a successful bid in respect of Certified Reserve Capacity through the Reserve Capacity Auction process.  A successful bidder may take the option of a 10-year Long-term Special Price Arrangement.  Short-term Special Price Arrangements can be established in the case where the IMO is required to procure capacity following a Supplementary Reserve Capacity Auction.  This would occur in the case of a Reserve Capacity shortfall. 

Short-term Special Price Arrangements can also be established, subject to certain conditions, when a Facility is in the position to commence operation earlier than 1 October in the year for which they have been assigned Capacity Credits. 

Under Market Rule 10.5.1(f)(vi) the IMO is required to publish the following information:

Special Price Arrangements for each Registered Facility:

  1. the amount of Reserve Capacity covered;
  2. the term of the Special Price Arrangement; and
  3. the Special Reserve Capacity Price applicable to the Special Price Arrangement,
where this information is to be current as at, and published on, January 7th of each year.

There are currently no Special Price Arrangements in place.
