3. Updates Frontera Settlement Retail Transactions Other Activities Retail Mechanics (Monte Jones) Reliability and grid operations (Sam Jones)

4. Frontera/APX Protocols were not totally clear in certain situations -- as a result: –Frontera expected to be paid as bid (OOMC) –Even though there was no “market solution” ERCOT contends that protocol’s intent was to cover variable costs plus a premium (10%) Frontera requested ADR to resolve issues

5. Frontera/APX (Cont’d) Unique circumstances existed: –ERCOT’s reliability needs (OOMC) were the primary reason for starting up the plant (92% of the time) over five months –Third party revenues were derived from ERCOT’s commitments, not the reverse –The plant had economic value to the merchant market, beyond ERCOT’s needs

6. Frontera/APX (Cont’d) Based on these factors, ERCOT offered an alternative approach: –Variable costs would be paid by ERCOT –Third party revenues would be shared in the same proportion as the ratio of variable to total costs –No fixed costs or premium would be allowed –Frontera would retain 100% of OOME payments

7. Frontera/APX (Cont’d) A settlement agreement is proposed: –That is fair to Frontera and to the ERCOT market –That covers six months of (past) operations, and –That identifies the need for future protocol changes that reflect these unique circumstances –Thereby establishing a context for future market discussions regarding reliability service

8. Retail Transactions Total transactions now exceed 2.5 million Sample data indicate that success rate is improving rapidly –814 transactions were within protocols >95% of the time –867 transactions were even better ETS will enable 100% sample evaluation
