e-Tagging timing requirements

e-Tag timing requirements have been highlighted as an issue in several stakeholder initiatives such as Convergence Bidding. The California ISO currently requires an e-tag no later than T-20 after adjustments in Hour-Ahead Scheduling Process (HASP). The large majority of market participants have voluntarily tagged Integrated Forward Market (IFM) awards prior to HASP. Several market participants have expressed concern that not requiring an e-tag for IFM awards prior to HASP can lead to implicit virtual bidding at interties and the feasibility of Day-Ahead schedules may be at risk.
