Report to TACFebruary 4, 2010
Henry Durrwachter
January RTWG Meeting
• Reviewed 4th Quarter TRIP Report• Lively discussion on potential changes in
the Texas Renewables Implementation Plan (TRIP)– Revised draft to be reviewed at next RTWG
meeting– Revised TRIP to TAC in March for review and
approval
• Discussed 2010 Work Plan
4th Quarter TRIP Highlights
• Installed wind generation capacity in ERCOT at December 31, 2009 = 8,916 MW
• The following new wind generation was added in the 4th Quarter of 2009:– Langford Wind Power 150 MW (Tom Green County)– Loraine Wind Park I 126 MW (Mitchell County)– Loraine Wind Park II 125 MW (Mitchell County)
• Total new wind generation capacity in ERCOT increased from 8,515 MW to 8,916 MW, an increase of 401 MW from the last report.
• One wind farm signed Generation Interconnect Agreements since the last report:– Paplote Creek Wind Farm II 198 MW (San Patricio County)

4th Quarter TRIP Highlights
• Significant Issues:– In November, the ERCOT Board approved
PRR 830 - Reactive Power Capability Requirement, which has been appealed to the PUCT
– In December, the PUCT issued a “strawman” rulemaking for the 500 MW non-wind Renewable Portfolio Standard (RPS)
4th Quarter TRIP Highlights
• Completed Issues:– MD-8: Reactive and Voltage Requirements
Applicable to Wind Generators– SO-9: SCADA Control of Generator Circuit
Breakers– SO-15: Communications between Wind
Farms and TSPs– SO-28: SPS Actuation for N-0 Conditions– WT-2: Wind Workshop III - Summer 2009– WT-4: Wind in the Nodal Market
4th Quarter TRIP Highlights
• Completed PRRs/NPRRs:– PRR 824 - Primary Frequency Response from
WGRs– PRR 830 - Reactive Power Capability
Requirement– NPRR 195 - Removal of McCamey
Congestion Management from Nodal Protocols
• New Issue: SP 9 - Wind Turbine Model Validation

ERCOT Wind Generation Facts 2009
• Annual average capacity factor = 24.4%• Capacity value of wind (as a % of installed capacity)
– At the peak hour (July 13, HE1700) = 18.4%– During the 4 monthly summer peak load hours (June-Sept.) = 9.2%.– For all hours in the 4 summer months = 19.8%
• Minimum hourly wind production was 14 MW on September 11, HE1000.
• Maximum hourly wind production was 5,986 MW on October 28, HE 2000.
• Highest percentage of load served by wind was 24.6 % on October 28, HE 0300.
• Maximum 1-hour increase in wind generation was 2,136 MW on October 25 from 6 to 7 PM.
• Maximum 1-hour decrease in wind generation was 1,820 MW on June 3 from 2 to 3 AM.
• This is the first year that there has been wind generation in every hour of the year.
