Background

Status: Approved
Date Posted: Sep 23, 2008

Urgent: No
Sections: 3.14.3, 6.6.11.1, 6.6.11.2, 8.1.3.1, 9.14.5
Description: This Nodal Protocol Revision Request (NPRR) proposes to correct terms contained in the Settlement equations related to EILS Self-Provision to make the formulas consistent with the verbal description of EILS Self-Provision Settlement and the author’s stated original intent. Specifically, the formula correction applies to the uplifted costs of EILS as defined in paragraph (3) of Section 6.6.11.2, as follows: · Clarifies that uplifted EILS costs are based on final adjusted EILS obligations after accounting for any self-provided EILS. This is accomplished by establishing and defining a new formula term, EILOF. · Adjusts other related formula terms accordingly. · Adds a missing subscript term definition that appears in numerous places elsewhere in the Protocols. · Adds clarity to certain other equation term definitions. This NPRR also makes clarifications in language contained in paragraph (8)(d) of Section 3.14.3 related to Qualified Scheduling Entities’ (QSEs’) EILS Self-Provision options in cases where less than 1,000 MW of EILS has been offered, and adds copies of definitions that are applicable to both equations in this Section. This NPRR also revises language to: · Clarify that the first Settlement of the Emergency Interruptible Load Service (EILS) Contract Period shall use a QSE Load Ratio Share (LRS) that is based upon the final Load for each Operating Day in the EILS Contract Period; · Introduce a resettlement of EILS Contract Period Settlement utilizing a QSE LRS which is based upon the True-Up Load for each Operating Day in the EILS Contract Period; · Remove conflicting language about EILS disputes; · Clarify the timing by which EILS Settlement disputes must be submitted; and · Move all language related to the timing of the EILS Settlement process to Section 9.14.5.
Reason: To provide certainty in Settlement for QSEs and EILS Resources offering into EILS via EILS Self-Provision.
