Sections: 6.5.12,
Description: This Protocol Revision Request (PRR) 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, 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 PRR also makes clarifications in language contained in paragraph (3)(d) of Section 6.5.12 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.
Reason: To provide certainty in settlement for QSEs and EILS Resources offering into EILS via EILS Self-Provision.
