LONG DESCRIPTION:
PRR803 is
changing the ramping period for Balancing Energy Service deployment for Base
Power Schedule Calculation and Balancing Energy Power Schedule from ten (10)
minutes to fourteen (14) minutes. This change is designed to provide more

implementation of PRR803 to ensure compatibility with the new fourteen (14)
minute ramping period, however, testing is not required. The attached document
(PRR803 - 14 Minute Ramp Rate Testing
Approach Overview) outlines the testing options and the scheduling
process. The testing period is July 1, 2009 through September 30, 2009.
Regardless of whether system testing is performed, all QSEs will be required to
submit documentation demonstrating that their systems are compliant with PRR803
prior to the proposed implementation date of October 29, 2009.
ACTION
REQUIRED: To
schedule a systems test, QSEs should contact their ERCOT Wholesale Account
