• Process & Assumptions– Data with 867 reads ending in July, August or September 2014 selected.– Data selected from database for analysis on October 27, 2014.– Selected all AMS reads with start times within 60 days of the first of the reporting month to

the last day of the reporting month.– Both estimated and actual 867 and AMS reads were selected.– Select 867 records that have AMS reads.

• If a record has an 867 but no AMS reads then the record is dropped.

– Sum up AMS totals for the period of the coinciding 867 read.– Calculate the delta between 867 and AMS kWh.

• (Delta kWh) = [(867 kWh) – round(AMS kWh)] / (867 kWh) • If both the 867 kWh and AMS kWh are zero then Delta kWh = 0.• If 867 kWh is zero and AMS kWh is non-zero then the comparison cannot be performed and the

record is removed from further reporting analysis.

• Disconnect Type Breakout– Data broken into three groups based on disconnect type.

• AMSR – Remote disconnect type, thought to have a meter multiplier of 1.• AMSM – Manual disconnect type, may not have a meter multiplier of 1.• Unknown – Remote designation type not designated
