  1. September 29,2014|VRWG Steven Weaver Manager, Operational performance, training and Integration Review of Existing Procedures Curtailment Procedures and Priority

  2. Minimum Generation – Post Wind Integration • CROP.25005 Minimum Generation • Minimum Generation Emergency • Software will dispatch Generators to Emergency Minimum • Day-Ahead transactions can be curtailed • If the above actions do not mitigate the Minimum Generation Emergency, non-dispatchable Generators may be reduced. (Wind is curtailed here) • In economic order using a bid de-stacker to EmerMin • Pro rata curtailment where prices are identical • Some latitude for inter-temporal constraints and system capacity • No wind has been curtailed for a Minimum Generation Emergency condition, post wind integration.

  3. Transmission Curtailment – Post Wind Integration • SOP-RTMKTS 0060 0020 Monitor System Security • Dispatchable generators to Economic Minimum • Deny Real-Time only Self Schedule Generators • Deny Day-Ahead Self Schedule Generators pro-rata • May be modified for any of the following • Thermal constraint sensitivity • System and area capacity • Minimum run and minimum down times • Other reliability concerns (i.e. voltage performance, stability) • Language added to SOP detailing process for making pro rata generator curtailments
