COPS NOVEMBER 2012 UPDATE TO TAC 11/29/2012 Harika Basaran, Chair Tony Marsh, Vice Chair

2 COPS MAJOR DISCUSSION ITEMS ERCOT’s proposal-Method for Paying Small Amounts: Applies only to Default, Late Fee, and Misc Invoices. If the amount due to MP is < $50, money will be deposited to the Pre-pay account. MP can request wire of the funds in prepay account any time via to ERCOT Credit. COPS agreed to ERCOT’s proposal. MPs must ERCOT each time when they have an amount less than $50 if they want the money to be wired. Default action by ERCOT will be to put the amount in the Prepay Account. ERCOT will set up prepay account for each entity if they don’t have already. Daily ACL report has the balance of the prepay account.

3 NPRR 377 Alternate Inputs to Base Point deviation Charge This NPRR aligns the Adjusted Aggregated Base Point (AABP) formula with the inputs to the Generation Resource Energy Deployment Performance (GREDP) measure. The current formula for AABP inaccurately assesses Base Point Deviation Charges for under and over generation when shortened Security-Constrained Economic Dispatch (SCED) intervals occur. The GREDP inputs are linearly ramped 5 minute data points as follows: AVGBP5M – Base Point instruction AVGREGUP5M, AVGREGDN5M, AVGREG5M – Regulation Instructions1 AVGTG5M – Telemetered Generation Current design is to include the 5 minute data for the above listed billing determinants in the existing Market Input Header and Market Input Interval tables. Number of columns will increase from 100 to 300. Some MPs concern is that too much data pushed in one table which may slow down data queries/uploads. COPS voted NO on this item so that ERCOT will NOT include 5 minute data in the extracts for now. CSWG discussed and agreed to sponsor an SCR for ERCOT to create a new extract that will include 5 minute data only.
