MSWG Nodal Handbook/Shadow Settlement Tools JANUARY 2018
Handbook Purpose/Purpose Served? Document Purpose With the advent of the ERCOT Texas Nodal Market, significant changes have been implemented to settlement processes and procedures for market participants. Nodal changes have brought about the increase in the number of bill determinants for settlement equations, the increase in the amount of data for reconciliation and the introduction of a Day Ahead market that adds additional settlement runs for each operating day. This document was created and maintained by the Settlements and Extracts Working Group (SEWG) is designed to serve as a reference guide for ERCOT market participants for settlement and related activities. The Communications and Settlement Working Group (CSWG) will maintain this guide based on market changes that arise from the ERCOT stakeholder process. PUBLIC
Also provides 1. An indexed presentation of all settlement charge types and various bill determinant calculations used in settlement charge types. 2. Appealing calculation graphics 3. A bill determinant grid to define bill determinants, specifying: ERCOT bill determinant name, unit of measure, description, interval frequency, data extract source, and whether the determinant is capable of being shadowed PUBLIC
