Lifting 1995 Caps

New Assessment Methodology Work
• Current forerunner has assessments based on
BA base charge, then rank by load
• Avoids double-charging some WECC members
• Proposing poll of BA Operating Committee
members and a technical session
• Work on numbers after 16-bucket
implementation

We Don’t Want to Use Tags!
• Incomplete representation of system
• Doesn’t account for untagged flows
• Volume of tags makes analysis cumbersome
and difficult – very complicated
• Access to tag data not readily available
• Could effect longevity of methodology

UFAS Charter
• Reviewed year in January
• Continued data sharing issues means UFAS
cannot meet charter obligations
• WECC is named in FERC Tariff Filing as
administrator of UFMP and does not have
access to data to do so

UFAS Charter, continued
UFAS cannot:
c. Collect, review, and analyze data related to USF events.
Report applicable findings on a regular basis to the WECC
OC.
d. Monitor coordinated operation of the Qualified
Controllable Devices.
UFAS can perform these duties, but ineffectively without
necessary data:
e. Develop or review guidelines to enable Path Operators to
implement actions that will achieve the desired results.
f. Review alternative policies, procedures, and
methodologies for dealing with unscheduled flow.
