May 2017 Meeting

NPRR 819ObjectivesImplement a resettlement threshold that is fair to large and small MPs, replacing the existing 2% resettlement ruleBase the resettlement threshold on the DAM and RTM median settlement statement amountsAddress the issue of small errors that cumulatively create an impact which exceeds a threshold that is fair to large and small MPsPropose actual daily resettlements, as opposed to alternative settlement resolution, to provide for automation and systematic historical referenceFor an error other than a pricing error that has a cumulative impact, designate a cutoff for the number of days the market will go back and resettleSet the cutoff for DAM resettlements due to the cumulative impact of an error other than a pricing error prior to the RTM True-up Resettlement, so its results are included in the resettlement of the RTM Add the number of resettlements due to errors other than pricing errors to the Settlement Stability Report for visibility into and review of the impact of NPRR819
