Overview of Divisional Accounting Project

*Bills and Financial Assurance determination remain unchanged

ISO’s settlement system provides one

account for each market participant

Market participants requested a divisional accounting option to create subaccounts that make sense for

their business

ISO New England began a multi-year, phased rollout in 2014 and has been phasing in software enhancements to fulfill this request• Provide subaccount level reporting in

settlement market information server (MIS) reports

• Enhance MIS reports to report activity by subaccount

Divisional accounting is an optional feature that allows customers to assign market activity to a subaccount or division for settlement reporting.

• Participants choosing to use the divisional accounting option will define their subaccounts in accordance with their business needs

• When Divisional Accounting is enabled, a Default subaccount is automatically assigned to the portfolio‒ Any assets, activities, or billing line items that are not associated with a user defined subaccount will be

reported in the Default*

Divisional Accounting Usage Overview

10

If you do not choose to use divisional accounting, no CAMS subaccount management

is required

If you choose to use divisional accounting, use CAMS to define subaccounts and map assets to

them per business needs

Remember to use theQuick Start Guide for Divisional Accounting

*Includes participant expenses and other miscellaneous charges

What is your business objective?

Business Objective One-time Actions Recurring* Actions for Activities (daily/as performed by your business)

Settle and report assets in a predefined subaccount

Define subaccount and determine which of your assets belong to it.

No activity assignment to this subaccount.

Settle and report activities that are not related to specific assets in a predefined subaccount

Define subaccount. You will not perform the entity mapping step available in CAMS.

Assign activities to subaccount during daily business process.

Settle and report assets and activities in a predefined subaccount

Define subaccount and determine which of your assets belong to it.

Assign your daily activities accordingly.

Settle and report assets and activities that have NOT been assigned to a subaccount

System-defined Default subaccount. All assets not assigned to a subaccount defined by you will belong to this subaccount.

Any activities not assigned to a subaccount will be reported in the Default subaccount.

* Recurring activities include demand bidding, virtual transaction submittal, internal bilateral transactions, external transactions and Forward Capacity Market self-supply. Additional activities for Financial Transaction Rights are currently only reportable in the default account.

Plan your subaccounts See the Quick Start Guide for details.

Map Your Subaccounts

Use the Customer and Asset Management System (CAMS) User Guide for Company and Affiliate Maintenance for mapping your assets to subaccounts• Use the completed worksheet from the Quick Start Guide to map your assets in CAMS to the

subaccounts you created• You can map the following types of assets to your subaccounts: generators, load assets, asset-

related demand, demand response assets, FCM resources, and regional network load• Note that FCM resources and energy assets are separate and distinct entities!

‒ For example, if your company is the lead market participant for an FCM resource, and also has an ownership share in the corresponding energy asset, both of these entities should be mapped to a subaccount if you want them reported in the subaccount together

16

Map assets to subaccounts in

CAMS

Generator offer inputs are not assigned to subaccounts through eMarket. Once the generator asset is mapped to a subaccount, all settlement information related to that asset will flow automatically to the subaccount.

You can choose to report demand bids which are not asset based in the same subaccount as a specific load asset(s).

20

Start using subaccounts

Assignment Type Example Video Example

Structure your demand and virtual transactions in the exact same manner as of today, and assign those activities to subaccounts

A participant serving load can now assign its load zone demand bid to a subaccount with the load assets (mapped in CAMS) related to that demand bid.

Example 1(DA & RT Load)

Example 2(Virtual Transactions)

Structure your demand bids and/or virtual transactions in a new manner, where multiple “like” activities can be submitted at one pricing location

A participant serving load in one load zone can submit multiple fixed demand bids at that zone and assign each one to a subaccount with the related load assets.

Example 3(Multiple “Like” Activities in onelocation)

Continue having some or all activities reported in the Default subaccount instead of assigning them to a CAMS subaccount

• A participant may want to make the subaccount determinations for these activities in the future

• Depending business needs, a participant may prefer the Default account for certain activities
