SCR768 Automatic Non-Spin Redeployment and Deployment Based on Resource Availability

Approved sponsor ERCOT posted 2011-11-02 ercot.com

ReasonThe current automatic redeployment implementation results in periods of reduced Non-Spin capacity during deployment as newly deployed Resources may take 25 minutes to show as deployed while recalled Resources may remove their deployment immediately. As such, it is not used. Since the current implementation deploys shortly after the start of each hour based on telemetry only, it also prevents a full hour deployment of Off-Line Non-Spin Resources, which could occur if the system provided advanced notice of deployment.

Summary

This System Change Request (SCR) modifies the Market Management System (MMS) Automatic Redeployment function such that it accounts for the delay involved in deployment of Off-Line Non-Spinning Reserve (Non-Spin) Resources.
