Description:	This PRR proposes a requirement that certain existing WGRs limit the unit ramp rate to ten percent (10%) per minute of their nameplate capacity ratings as registered with ERCOT.
Reason:	This PRR is a follow-up to PRR771, which required ramp rate limitations for WGRs with signed Interconnection Agreements on or after Jan. 1, 2009. This PRR addresses units with signed Interconnection Agreements prior to Jan. 1, 2009.
