  • Outage QueryWHERE outage.CATEGORY = 'Transmission AND outage.planned_end_date >= (ADD_MONTHS (TRUNC (LAST_DAY (SYSDATE) + 1), 1)) -- this gives you the current month plus 2 AND outage.planned_start_date
  • Outages / Outage Selection ProcessNodal Operating Guides 5.5(6): System Modeling Information

    (6) Congestion Revenue Right (CRR) Network Model Outage determination uses network topology of the CRR Network Model identified by ERCOT. This must include Planned Outages of Transmission Elements approved by ERCOT at the time the CRR Network Model is being built and that demonstrate significant impact to the transfer capability during the effective period.ERCOT will consider including Outages in the CRR Network Model that are scheduled to occur in the relevant time period and meet one or more of the following criteria: (a)Consecutive or continuous approved Outages greater than or equal to five days;(b)Approved Outages which include Transmission Elements included in the definition of a Hub;(c)Approved Outages which include Transmission Elements in a 345 kV Transmission Facility;(d)Approved Outages that require the use of a Block Load Transfer (BLT); and(e)Any other approved Outage that has been determined by ERCOT to carry a substantial risk of causing significant congestion.

  • Outage Date SelectionMarket Operator (MO) uses the base case flows in the On-Peak SSWG case for the appropriate year and season to qualitatively estimate the severity of the outaged lines.MO chooses the worst day of the month based on the evaluation from the step above as well as special consideration given to (in descending order) outages involving:Lines in the W->N constraint Lines in the N->H constraintLines involved in other 2010 CSCs/CREsMO imports the outages into TP the and builds the network model based on those outages.
