Summary
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.
