Background

Status:	Approved
Date Posted:	Apr 15, 2008
Sponsor:	Walter Reid on behalf of Wind Coalition
Urgent:	No
Sections:	3.1.4.1, 3.1.4.6
Description:	This Operating Guide Revision Request (OGRR) proposes a requirement for VRT capability for all new generating units.
Reason:	This OGRR is being proposed for the following reasons: (1) Passing of FERC 661A, Eminent NERC Standard drafting process takes time; (2) Although wind manufacturers are adding VRT capability to new designs, we must proceed before NERC due to large amounts of proposed wind generation next year and next few years in ERCOT that could pose a reliability threat in the event of voltage excursions; and (3) Concern of sudden voltage changes causing tripping of units without VRT capability.
