been relocated or deleted, please see the Table of Concordance.
ISO rules Section 6 sets out requirements for the AESO in issuing dispatches and
directives for energy, dispatch down service, and long lead time pool assets.
These rules also set out the requirements for pool participants in receiving and
complying with those dispatches.
In general, provisions addressing unusual market conditions such as long lead
time energy, dispatching equal prices and involuntary load curtailment, have been
relocated to proposed New ISO Rules Division 202 Non-Routine Conditions in the
Markets.
Requirements addressing energy or dispatch down service under normal
operating conditions have been relocated to proposed New ISO Rules Division
203 Energy Market or proposed New ISO Rules Division 204 Dispatch Down
Service, respectively.
In general, ATCO Power is supportive of the proposed
deletions. However, in the cases where content is
relocated to the System Controllers Procedures our
comment is that this should be done with careful
consideration. Even though certain actions are clearly
the responsibility of the System Controller, in some
cases it may be beneficial to allow market participants
to retain visibility of the System Controller requirements.
This would allow market participants to anticipate
actions they may need to take to assist the System
Controller in meeting its requirements.
ISO rules Section 6 also sets out requirements on the AESO’s pricing
methodology. This content has been moved to proposed New ISO rules Section
201.6 Pricing.
Existing ISO Rules Subsections 6.4 and 6.5 address dispatches and directives for
ancillary services. Requirements that address contracted ancillary services such
as black start, voltage support, or power system stabilizers have been removed,
as these products are administered through contracts. Requirements for
transmission must run have been relocated to proposed New ISO rules Section
205.8 Transmission Must Run. Requirements addressing dispatches and
directives for operating reserves will remain in existing ISO rules Section 6 and
will be removed at a later date as these requirements are transitioned into the
future proposed operating reserves rules.
ISO rules Subsection 6.6.2(b) sets out requirements for regulating reserve. These
requirements will remain in ISO rules Section 6 and will be transitioned into the
future proposed operating reserves rules.
ISO rules Subsection 6.7 addresses system security. This section will remain in
the existing ISO rules framework and will be transitioned at a later date.
