Listed below is the summary description of changes for the proposed new, removed or amended sections of the ISO rules. Please refer back to the Letter of Notice under the “Attachments to Letter
of Notice” section to view the actual proposed content changes to the ISO rules. Please place your comments/reasons for position underneath (if any).
1. ISO Rules
a) Amended
The words “excluding a wind facility” were deleted from subsection 1(a),
resulting in Section 306.5 applying to all types of generation source assets,
including wind aggregated generating facilities.
The AESO is seeking comments from stakeholders with regard to the
following matters:
1. Do you agree or disagree with the proposed Section 306.5? If you
disagree, please provide comments.
Stakeholder Comments and/or Alternate Proposal
AESO Replies
1. The AESO’s definition of a scheduled generator outage is “… the period
of time as planned by the legal owner of a generating unit or the legal
owner of an aggregated generating facility during which that generating
unit or aggregated generating facility is partially or fully removed,
derated from, or otherwise is not physically or mechanically available for
service due to planned or scheduled maintenance or repairs to any of
the plant, equipment or components of the generating unit.
ENMAX supports this definition and, based thereon, assumes that the
owner of a wind aggregated generating facility need not report to the
AESO when the facility is partially or fully derated or otherwise not
physically available for service due to a loss of wind. Should ENMAX’s
assumption be incorrect, it would be useful to make the reporting
requirement due to a loss of wind explicit in the rule.
2. Are there any subsections where the language does not clearly
articulate the requirement for either the AESO or a market
participant? If yes, please indicate the subsections and suggest
language that would improve the clarity.
2.
Subsection 2(1) states that “A pool participant must, for any outage that
results or will result in a change in available capability of five (5) MW or

greater, comply with the notification requirements set forth in subsections
3, 4 or 5, as applicable.” Subsection 25(4) of proposed ISO rule 502.1
states that “Any wind aggregated generating facility must provide to the
ISO the current and planned available capability down to the real power
equivalent of one (1) wind turbine generator.” It would be helpful if the
two MW requirements—5 MW or the size of one wind turbine generator—
were made consistent for wind generators (since most individual wind
turbines in Alberta are less than 5 MW).
