Project Overview

Target launch for phase 11: TBD

The Divisional Accounting project was developed to address requests from participants for the ability to assign settlement accounts to business units for reporting purposes. Under the project, user-defined subaccounts allow customers to segregate their settlement reporting according to their business needs. Participants can designate assets and resources directly to a subaccount in the Customer and Asset Management System (CAMS); other activity-based transactions are assigned in their respective applications, such as eMarket, the Forward Capacity Tracking System (FCTS), and the Internal Transactions interface. As this project touches multiple user interfaces and reporting systems, implementation has been performed over several phases beginning in 2014. The project phases as implemented or planned to date are as follows:

Phase 1 (Q1 2014): Subaccount creation and management in CAMS added
Phase 2 (Q2 2014): Asset assignment to subaccounts in CAMS reflected in most reporting for hourly markets, the transitional demand response program, and blackstart settlement
Phase 3 (Q4 2014): Asset assignment to subaccounts in CAMS reflected in Net Commitment-Period Compensation (NCPC) settlement reporting
Phase 4 (Q1 2015): Asset assignments to subaccounts in CAMS reflected in Regulation Market settlement reporting
Phase 5 (Q3 2015): Most activity entry point assignments to subaccounts reflected in settlement reporting
Phase 6 (Q3 2015): Subaccounts reflected in Forward Capacity Market (FCM) settlement reporting
Phase 7 (Q2 2016): Subaccounts reflected in Open Access Transmission Tariff (OATT) and ISO Self-Funding Tariff settlement reporting
Phase 8 (Q2 2016): Informational reporting for billing amounts by subaccount available
Phase 8a (Q2 2019): Informational reporting for billing amounts by subaccount in individual files
Phase 9 (Q4 2019): Assign external transactions to subaccounts using NEXTT user interface – refer to the project page for more information
Phase 10 (Q2 2020): New market information server (MIS) reports for individual subaccount reporting for Day-Ahead and Real-Time Energy
Phase 11 (TBD): Financial Transmission Rights and Auction Revenue Rights may be reflected in user-defined subaccounts

Implementation planned under other projects:

Upgrade subaccounts to reflect Forward Capacity Market Capacity Transfer Rights (FCM CTRs) – project TBD

Specific quarters as implemented since 2012	Quarterly Settlements Issues Forum (QSIF) Various sessions of the QSIF provided updates throughout the project. The following forums have additional information beyond project updates that you might find helpful: The Settlements Issues Forum: Q3 2012 Presentation provides an overview of the project and objectives. The Settlements Issues Forum: Q4 2013 Presentation describes the rules for the allocation of NCPC load obligation deviations. (Recording available.) The Settlements Issues Forum: Q1 2014 Presentation describes the rules for allocation of Forward Reserve Market (FRM) Failure-to-Reserve penalties. (Recording available.) The Settlements Issues Forum: Q3 2015 Presentation highlights the importance of testing your subaccounts. (Recording available. Also see the Quick Start Guide for Divisional Accounting for more current instructions.) The Settlements Issues Forum: Q2 2015 Presentation explains the difference between settlement of activities that can be associated with specific assets and market activity that cannot be directly tied to an asset and thus, assigned to a subaccount at the point of entry. (Recording available.) The Settlements Forum: Q2 2019 Presentation explains that FTRs and ARRs will be available initially in the default subaccount for participants that use divisional accounting and the ability to assign subaccounts to FTRs and ARRs will be coming in a future phase. (Recording available.) The Settlements Forum: Q3 2019 Presentation explains that subaccounts will be available in the New England External Transaction Tool (NEXTT) which will replace the Enhanced Energy Scheduling application.
