Posted 7/13/07: OASIS
Temporary Suspension of Short-Term Firm Competition Market
Transmission Services discovered an issue with
how the wesTTrans OASIS system (OASIS) implemented the competition rules for
initiating competitions for the Short-Term Firm (STF) Market (see discretionary
log #43708 posted on OASIS). As a result, Transmission Services has temporarily
suspended STF competition and is currently working diligently with OATI to
provide a solution that would allow OASIS to correctly perform STF competitions.
STF requests will continue to be processed over OASIS. The suspension applies
only to the competition aspect of STF ATC evaluations.
OASIS ATC Notes
The ATC
margin documented in the posted related ATC Methodology document as "ATC
Methodology Margin" (AMM) will be posted in the OASIS field labeled "Transmission
Reliability Margin" (TRM). Rounding is applied to the displayed path MW values
posted in OASIS Sys Data. For additional details see, OASIS ATC
Notes.
BPA Transmission Services determines
Long-Term Firm (LTF) Available Transfer Capability (ATC) values assuming all
lines are and will be in service. The firm ATC values currently posted on the
BPA Transmission Services OASIS site include Total Transfer Capability (TTC)
reductions for planned outages. These TTC reductions do not affect LTF ATC. As
a result, the LTF ATC and TTC values posted on OASIS are lower than actual values
used in LTF ATC evaluations. The Short-Term Firm ATC and TTC values posted on
OASIS are accurate.
