ad hoc timeline review team mark -
the ad hoc team ' s product is attached . it is a suggested revision to the
nerc a 3 al time table for the wscc . some basic points are :
* elimination of manually setting the wscc pre - schedule flag . the
table provides rules for the e - tag software to automatically set the flag .
* the majority of our efforts were focussed on creating an incentive
mechanism to encourage timely tag submission and assessment . the team
agreed that the best incentive mechanism would be a financial one ( i . e . ,
tags submitted close to the deadline would pay a high submittal fee - tags
submitted early in the hour would pay little or no submittal fee - approval
entities would receive compensation for assessing / approving late tags ,
etc . ) . but , a financial mechanism would have to go through a cumbersome
review / approval process which would be too inflexible for the fast paced
world of e - tag and nerc ' s electronic scheduling . so , the suggested
incentive process increases the risk of a tag not being approved the closer
the submittal time is to the start time . to do this , we considered three
parameters - the assessment window , deferred denial , and the default
composite status .
* the assessment window is a period time that the e - tag
authority service gives the approval services to assess a submitted tag .
each approval service is to check the tag for various things and respond
with a approved or denied vote back to authority service who then set the
final composite status .
* deferred denial is when a entity denies a tag , the composite
status does not immediately become denied , but instead waits until the end
of the assessment window to set the composite status . this allows the
denying approval entity time to reconsider their vote and change it , if
appropriate .
* the default composite status is a final stated reached at
the end of the assessment window when one or more approval entities fails to
actively approve or deny a tag . currently , tags submitted before a certain
deadline will have their final composite status default to approved . tags
submitted after a certain deadline will have their final composite status
default to denied .
for real - time tagging , we cite the hour - ahead business where
purchasing - selling entities trade products for delivery in the next hour .
* tags submitted in the first half of the hour - ahead , referred
to 0 to 30 past , will have a 10 minute assessment window , are subjected to
deferred denial , and will default to approved / conditional .
* tags submitted from 30 to 40 past , will have a 10 minute
assessment window , are not subjected to deferred denial ( can be called
instant denial ) , and but will still default to approved / conditional .
* tags submitted in the after 40 past , will have a 5 minute
assessment window , are not subjected to deferred denial ( can be called
instant denial ) , and will default to denied ( thus assigned a composite
status of late ) .
* the table references specific times in the submittal and assessment
process which should all reference a consistent time zone standard . the
team was divided on the best approach . some suggested all times on the
table be the prevailing time for the lca . this would require each ca to
include in the e - tag registry their time zone . some suggested all times on
the table be in pacific prevailing time . and some suggested that all times
on the table be in pacific standard time . the conclusion is that a white
paper would be produced prior to the july isas meeting discussing the pros
and cons of each suggestion .
* the group does not recommend basing submittal time on the tag
agent ' s time clock - submittal time should stay with the authority service .
* here ' s a big one - because the timing table allows for later
submittal times , the tag assessment process is encroaching on the start of
the wscc standard ramp ( i . e . , currently starts at 10 minutes before the
hour ) . we are recommending that isas request the oc to study the
feasibility of moving the wscc standard ramp from a twenty minute duration
straddling the hour to 10 minute duration straddling the hour ( i . e . , starts
at 0 : 55 and ends at 0 : 05 ) . such a change would align the wscc with the
eastern interconnection and relieve some of the issues surrounding late tag
submittals .
* there was some discussion on establishing a new regional practice
for the tariff deadline for schedule changes ( most are set to 20 before the
start ) . it was felt that there is little chance at getting all entities to
change their tariffs in a coordinated and timely manner .
* the team did not want to address at this time issues concerning
multiple preschedule days and how they are not recognized in policy 3 or the
e - tag specifications .
* finally , the team can not stress enough that a composite status of
late should not and does not mean automatic denial . the late designation
simple indicates that the default composite status is denied . approval
entities should make every effort to assess all tags , late or not .
hurray for the team members , many , many thanks .
