3 Determination of NDM Supply Meter Point Demand
(b) EUC 2 for NDM Supply Meter Points with an Annual Quantity equal to or greater than 73,200 kWh (2,500 therms) but less than 732,000 kWh (25,000 therms); and
(c) EUC 3 for NDM Supply Meter Points with an Annual Quantity equal to or greater than 732,000 kWh (25,000 therms).
2.3 The Operator will develop and maintain a mathematical model, the "NDM Demand Model", which the Operator shall use for the purposes of:
(a) establishing the relationship between weather and demand at NDM Supply Meter Points; and
(b) estimating the aggregate demand at NDM Supply Meter Points in each EUC before, during and after each Gas Flow Day.
2.4 The NDM Demand Model variables will be derived from:
(a) actual and forecast weather data;
(b) NDM and Very Large DM Supply Meter Points or DM Supply Meter Point (as applicable) demand records maintained by the Operator;
(c) actual and forecast gas flows at BSEPs and TSEPs;
(d) actual and forecast gas flows at Very Large DM Supply Meter Points or DM Supply Meter Points (as applicable);
(e) the Daily Shrinkage Quantity and the sum of each User’s Daily Shrinkage Nomination Quantities;
(f) actual or forecast quantities of gas to be vented in accordance with Section G paragraph 7.6; and
(g) adjustments (if any) to the System Daily Quantity Delivered for a Gas Flow Day.
3 Determination of NDM Supply Meter Point Demand
3.1 In respect of each NDM Supply Meter Point the "Supply Meter Point Demand" is the quantity of gas deemed to be offtaken on a Gas Flow Day at the NDM Supply Meter Point determined in accordance with this paragraph 3.
3.2 The Supply Meter Point Demand for a NDM Supply Meter Point shall be determined:
(a) before the Gas Flow Day, for the purposes of the Operator determining Nomination Quantities for Users NDM Offtake Nominations, as:
EUC(D) / EUC(AAQ) * AQ
(b) before 12:00 during the Gas Flow Day, for the purposes of the Operator determining Nomination Quantities for Users NDM Offtake Renominations, as:
(EUC(D) / EUC(AAQ)) * AQ * SF(f)
