Appendix "D-2" – Energy Rate Calculation

The Energy Rate Calculation will be based on a monthly electric energy price and will establish a monthly RRT rate.  The monthly electric energy price will be established based on New RRO Arrangements, Other Procurement Arrangements for each month.  Except as set out in this Appendix, capitalized terms in this Energy Rate Calculation will have the meanings set out in Appendix "D-3". 

1. Monthly Energy Price Methodology

The "Monthly Energy Price" will be expressed in dollars per kWh, and will be the weighted average of the "New RRO Arrangements Price" the "Other Procurement Arrangements Price," plus adders for Load Shape Adjustment, Load Swing, Unaccounted For Energy and Line Losses (UFE/LL), Return Margin, Pool Trading Charges, and Payment in Lieu of Taxes as applicable. 

The Monthly Rate will be applied to actual electric energy delivered to Eligible Customers.  The Monthly Energy Price will be determined as follows:

where:

"Adders" means the components of the Monthly Energy Price added to the Base Hedge Price and New RRO Price, and include:

(a) "Load Shape Adjustment";
(b) "Load Swing";
(c) "UFE&LL", where "UFE&LL" means the average Unaccounted for Energy and Line Losses for the last 12 months, expressed as a percentage, and determined using final Settlement data provided by ENMAX Power Corporation;
