Background
| Status: | Approved |
|---|---|
| Date Posted: | May 12, 2010 |
| Sponsor: | ERCOT |
| Urgent: | No |
| Sections: | 6.5.7.10 |
| Description: | This Nodal Protocol Revision Request (NPRR) proposes a requirement that certain Wind-powered Generation Resources (WGRs) limit the unit ramp rate to 10% per minute of their nameplate rating as registered with ERCOT. The proposed language is based on the concept set forth in zonal Protocol Section 6.5.13, WGR Ramp Rate Limitations. |
| Reason: | The intent of this NPRR is to maintain system reliability as it allows ERCOT to avoid frequency spikes due to WGRs’ ability to ramp up or ramp down almost instantaneously. |
