Request for Stakeholder Comments on
AESO Recommendations for Revisions to
Generating Unit Owner’s Contribution Provisions
Background
On October 16, 2012, the AESO published its Recommendations for Revisions to Generating Unit
Owner’s Contribution ISO Rule and ISO Tariff Provisions, which outlined proposed revisions related to
contributions paid by and refunded to owners of generating units in accordance with section 29 of the
Transmission Regulation. Those provisions currently exist in:

ISO rule 9.5: Annual Performance Criteria for Refund of System Contribution;

ISO tariff section 10: Generating Unit Owner’s Contribution; and

Generator System Contribution Policy.
The AESO proposes to implement the ISO rule and information document changes in January 2013 and
to include the ISO tariff changes in the AESO’s next tariff application in March 2013. The AESO is
seeking comments from stakeholders on the proposed changes as presented in the recommendation
paper.
Please use the comment form below when submitting comments to the AESO on the proposed revisions.
Please ensure that your comments represent all interests within your stakeholder organization with
respect to the proposed revisions. Please provide comments or questions no later than November 5,
2012, to Raj Sharma at [email protected] or 403-539-2632.

Stakeholder Comments on AESO Proposals
Stakeholder Comment
3.1.2
Stakeholder Position
The AESO proposes that all provisions relating to generating unit owner’s contributions
should apply at the generating unit level (or at the aggregated generating facility level, in
the case of an aggregation of generating units designated as such by the AESO, as for a
wind generating facility using multiple wind-powered generators).

3.2.2
Stakeholder Position
The AESO proposes that generating unit owner’s contribution provisions relating to Rate
STS contract capacity be revised to accommodate:

increases or decreases in capacity included in a “staged” Rate STS contract; and

increases or decreases in capacity implemented through an amendment to a Rate STS
contract after commercial operation.

4.1.2
The AESO proposes to use an availability-based criterion where possible instead of the
current production-based criterion to assess utilization of the interconnected electric
system.
As well, the AESO proposes that the annual refund amount would vary linearly from zero
refund to full refund across a range of average availability, to avoid the “cliff” created by a
single threshold level.
