Texas Renewables Integration Plan (TRIP)
The TRIP is detailed look at many of the policies, issues and strategies impacting the development and integration of renewable resources in the competitive electricity market in ERCOT. It is a living document that will be updated annually (typically in February each year).

The TRIP Quarterly Report
A separate document, the TRIP Quarterly Update, will be provided after the end of every calendar quarter (i.e., March, June, September and December) to the ERCOT Board and the PUCT to inform those bodies of status of renewable resources installed in ERCOT and the disposition of various issues identified by the RTWG and assigned to ERCOT subcommittees, task forces and working groups to resolve.

TRIP Quarterly Update (Draft)• Total wind generating capacity = 8,135 MW (through May,
2009)• New wind generation added in since February, 2009:
– Goat Wind (Phase 2) 70 MW (Sterling County)• New Renewable Resources with Signed Interconnect
Agreements (1,100 MW) since February, 2009:– Senate Wind (150 MW)(Jack County)– Lenorah Wind (200 MW)(Frio County)– Sterling Energy Center (300 MW)(Sterling County)– Langford Wind Power (150 MW)(Tom Green County)– Panther Creek 3 Wind (200 MW)(Concho County)– Nacogoches Biomass (100 MW) (Nacogdoches County)

Questions for TAC
• Does the TRIP document capture all the necessary information for the Board and PUCT?
• Does the TRIP quarterly update provide adequate information?
• Does the quarterly update need to coincide with calendar quarters (i.e., March/June/Sept/Dec)?
9
Next Steps
• Finalize TRIP based on feedback from TAC, ERCOT Board, and PUCT (July).
• Work with ERCOT Operations to finalize schedule and speakers for Wind Workshop III.
• Establish timelines for each identified issue.• Develop and begin review of whitepapers for
issues in the Undetermined category.• Assign new issues identified to the appropriate
ERCOT subcommittee.
