Sponsor:	Luminant Energy Company LLC
Urgent:	Yes
Sections:	4.5.2
Description:	This Protocol Revision Request (PRR) changes the divisor for the minimum ramp rate required for a Balancing Energy Service Down bid from 40 to 56 to reflect the change resulting from the implementation of PRR803, Revised Implementation Approach for PRR 601, as it relates to the number of minutes of Balancing Energy Service ramping over a one-hour time period.
Reason:	The language in Section 4.5.2 related to minimum ramp rate requirement was not properly revised to reflect the 14-minute ramp rate period (i.e., seven minutes prior to the start of the Settlement Interval and seven minutes after the start of the Settlement Interval) as required in paragraph (18) of Protocol Section 6.5.2, Balancing Energy Service, as part of PRR803. This PRR addresses that oversight and aligns Section 4.5.2 to the 14-minute ramp rate period incorporated in the implementation of PRR803. If this change is not made, QSEs complying with the mandatory Balancing Energy Service Down requirement may not be able to meet the current ramp rate requirement and the current Protocol language effectively requires QSEs to supply 140% of the mandatory minimum Balancing Energy Service Down requirement to meet the ramp rate requirement.
