IDCWG Update GTL Update

IDCWG Update GTL Data Submission

IDCWG Update Most entities are now submitting close to full set of data for generation and load. Calculation testing may take place with this data. Entities will be able to submit data every 15 minutes at minimum. OATI may interpolate data for those who can’t submit data every 5 minutes.

IDCWG Update Change Order 283 Status

IDCWG Update During the upcoming March session, OATI will provide an educational session on GTL. We plan to perform calculation testing during this session. Calculation testing may now take place with the submitted data. Comparison of Real Time flowgate flow versus calculated impact on the flowgate by GTL. Comparison of GTL calculated Market GTL impacts versus those Market Flows calculated by the market entities. CO 322 (Generation Priority Submission) is evaluated and will be developed once a BPS solution is finalized.

IDCWG /BPS Outstanding Items BPS to categorize its audience for the purpose of viewing reliability metrics (CO 326) With all the real time data being used for curtailments, is there a discussion about making TLR process run more than just once an hour? On CO 322 (Generation Priority Submission), it is assumed that only RC or BA will submit the priorities. Is there a need to design the registration process on more granular level (TO, GO, etc…)?
