In March 2015, Gas Industry Co held a workshop with retailers to present a D+1 model developed by Concept Consulting.  This model uses regression analysis to allocate the previous day's gas consumption to shippers based on past consumption patterns.  Gas Industry Co proposes to use this model as the basis for a trial of D+1 allocation.  The trial would be a low-cost way of determining whether D+1 would be worthwhile to implement as part of the Reconciliation Rules; and, if so, of refining the methodology and processes used.
