ISO-NE implements two more phases of the Divisional Accounting Project; See the new Customer Readiness webpage for complete project details

One new phase added; implementation date TBD

ISO New England launched the multi-year Divisional Accounting project to address requests from market participants to segregate settlement reporting into subaccounts for individual business units, divisions, or generating facilities. 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. Financial assurance determination and billing/invoice will continue to be at the customer level (i.e., the aggregate of the subaccounts).

As this project touches multiple user interfaces and reporting systems, implementation has been performed over several phases beginning in 2014. Below is a summary of the implementation phases. For a comprehensive list of training materials, user guides, and other reference materials for market participants who elect to enable and use divisional accounting reporting, please see the Divisional Accounting Project page under the new Customer Readiness section of the ISO website.

Completed Phases

The following phases allowed participants to assign assets to subaccounts, thereby enabling divisional accounting reporting for market activity that can be readily associated with assets (e.g., generator payments).

• Phase 1 (Q1 2014): CAMS subaccount management available
• Phase 2 (Q2 2014): Asset assignment to subaccounts in CAMS reflected in most Hourly Markets/ Transitional Demand Response/ Black Start Settlement reporting
• Phase 3 (Q4 2014): Asset assignment to subaccounts in CAMS reflected in NCPC settlement reporting
• Phase 4 (Q1 2015): Asset assignments to subaccounts in CAMS reflected in Regulation Market settlement reporting
• Phase 5 (Q3 2015): Demand bids, virtual transactions, and internal bilateral transactions (IBTs) assignments to subaccounts in eMarket and the Internal Transaction application
• Phase 6 (Q3 2015): FCM settlement reports reflect FCM resource assignments and self-supply MW can be applied to subaccounts through the Forward Capacity Tracking System (FCTS)
• 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

Future Phases

• Phase 9 (TBD): Financial Transmission Rights, Auction Revenue Rights, and external transactions may be reflected in user-defined subaccounts
