Background
| Status: | Approved |

| Sponsor: | Luminant |
| Urgent: | No |
| Sections: | 2.1, 2.2, 4.4.15, 4.5.12 |
| Description: | This Protocol Revision Request (PRR) revises the probability of exceedance percentage applicable to the Total ERCOT Wind Power Forecast (TEWPF) from 80% to 50% to better reflect the total ERCOT Wind-powered Generation Resource (WGR) production that has been historically experienced. |
| Reason: | These revisions are intended to better reflect the actual accuracy experienced by ERCOT’s use of the AWS Truewind forecast of wind generation in the ERCOT TEWPF based on historical information presented at the November 10, 2009 QSE Managers Working Group (QMWG) meeting. This change is also necessary to comport with the ERCOT Board remand of PRR811, Real Time Production Potential, to the Technical Advisory Committee (TAC) due to a lack of a specific calculation methodology for the Real Time Production Potential (RTPP) of a WGR. |
