Background

Status:	Approved
Date Posted:	Jan 20, 2009
Sponsor:	ERCOT
Urgent:	Yes
Sections:	4.10.5
Description:	This Protocol Revision Request (PRR) re-defines the Day Ahead metric for both Wind-powered Generation Resource (WGR) Qualified Scheduling Entities (QSEs) and non-WGR QSEs to ensure that both categories of QSEs schedule enough capacity in the Day Ahead market to meet their planned energy schedules plus Ancillary Service (AS) Obligations. This PRR removes the WGR QSEs exemption established in PRR 777, WGR QSE Metric Correction.
Reason:	PRR777, WGR QSE Metric Correction, addressed the disconnect between the energy schedules and the requirement to set the planned output in the Resource Plan equal to the ERCOT-provided Wind Power Forecast. This PRR establishes a requirement to schedule enough capacity to cover energy schedules plus AS Obligations in the Resource Plans for all QSEs. The Day Ahead Replacement Reserve Service (RPRS) market does not use energy schedules as input. RPRS uses the Resource Plan capacity, ERCOT Load Forecast and Ancillary Service Requirements as input. Protocol Section 4.1.1, Day Ahead Scheduling Process, states that ERCOT will verify that Resource Plans are sufficient to meet QSEs energy schedules. ERCOT proposes a change that would verify that all QSEs have sufficient capacity in their Resource Plans to meet their energy schedules.
