Background

Status: Approved
Date Posted: Oct 2, 2014
Sponsor: Thompson & Knight LLP, on behalf of Texas Industrial Energy Consumers (TIEC)
Urgent: No
Sections: 6.5.7.3
Description: This Nodal Protocol Revision Request (NPRR) addresses proxy Energy Offer Curves generated by ERCOT for a Resource that does not submit an Energy Offer Curve or submits an incomplete Energy Offer Curve. For a Resource without an Energy Offer Curve, a monotonically increasing proxy Energy Offer Curve will be created such that the last point on the curve is extended. For a Resource with an incomplete Energy Offer Curve (typically cogeneration facilities that update their HSL, but not their offer curve), a proxy Energy Offer Curve will be created to extend the offer price from last point on the submitted Energy Offer Curve up to the Resource's HSL.
Reason: Addresses current operational issues where proxy offers utilitizing the System Wide Offer Cap (SWCAP) may negatively impact Security Constrained Economic Dispatch (SCED) results.
