DESCRIPTION

3 Subtractive/Additive Metering Data Requirement –ERCOT TDSPs sending netted 15 minute interval data –Non-ERCOT TDSPs sending all 15 minute interval data Solution = Adopt ERCOT TDSP methodology Mid Cycle Meter Read with Profile Change –Caused by change in IDR, Demand, or TOU status –4 Options considered, no good compromise solution determined Solution = Change the meter on cycle read date Meter Reads required on Historical Usage Request –Present interpretation requires both meter read and consumption Solution = Drop requirement to provide meter read Consumption Discrepancy –Interval data does not match consumption data Solution = Revise Tx SET transaction to allow for adjustment Critical Retail Issues RMS Update Retail Metering

• Analysis of the 62 Critical Issues– 12 - Business process definition requiring no system change– 24 - Business system change required by point-to-point MPs– 26 - Business system change required by all MPs, ERCOT included

• Analysis of the 26 change issues effecting ERCOT– 10 - Priority 1 - essential for Market Open– 8 - Priority 2 - important for Market Open– 8 - Priority 3 - after Market Open

• Analysis of the 10 Priority 1 issues– 4 - Retail Metering, not Protocol changes required– 3 - Permit/Inspections, will require Protocol changes– 3 - Move In/Move Out, will require Protocol changes

• Mid Cycle Meter Read with Profile Change– Caused by change in IDR, Demand, or TOU status– 4 Options considered, no good compromise solution determinedSolution = Change the meter on cycle read date

• Meter Reads required on Historical Usage Request– Present interpretation requires both meter read and consumptionSolution = Drop requirement to provide meter read

• Consumption Discrepancy– Interval data does not match consumption dataSolution = Revise Tx SET transaction to allow for adjustment

• Existing Process Creates Service Gaps

– Option 1 - No change, deal with customer problems– Option 2 - CR manages and communicates problem– Option 3 - ERCOT manages and communicates problem

• Timing Requirement when CSA in effect– Service not disconnected at Move OutSolution = Clarify timing requirement, ERCOT ensures switch in 1 business

day• Same CR on a new Move In

– CR responsible for final bill determinationSolution = Change existing reject code reason
