Internal Market Monitor Asset Characteristics (IMMAC) Project

Below, affected ISO customers can learn more about actions they’ll need to take and changes to existing systems or procedures related to the Internal Market Monitor Asset Characteristics Project. This project was one of several that ISO New England has undertaken, in collaboration with stakeholders, for the continued development of the region’s wholesale electricity markets.

See Participant Readiness Project Outlook for more detail on specifically affected customers and systems for this and other major projects.

Project Overview

Project Implemented: July 11, 2017

A new user interface was added to the Customer and Asset Management System (CAMS) for use by lead market participants with generator assets in submitting asset characteristic data to the ISO’s Internal Market Monitor (IMM). Lead market participants of settlement only generators were not required to use this interface. The new IMMAC module replaced the previous process, which involved information submittals via email and manual data entry. The new IMMAC module:

• Provides better transparency, by enabling market participants to view the current values of their reference parameters on record with the IMM
• Reduces data errors and mitigation issues, by applying data validations and formats at the point of data entry
• Allows submittal of supporting documentation at the time of data change request
• Leverages existing CAMS generator asset data to avoid duplicate submittal requirements or inconsistencies between datasets
• Shortens the time from data submittals to data updates in the current system and eliminates manual documentation of every entry for audit purposes
• Simplifies the training required for IMM analysts to maintain asset characteristics, by eliminating the need to learn underlying database structures to use the application
• Allows for easier, faster upgrades and enhancements of the application in the future

Required Participant Actions

Affected market participants were required to take specific steps or adapt to changes in ISO Systems, as described below and should be mindful of additional time-bound items, some of which may require customers to take specific steps or adapt to changes in ISO systems both before and after the project implementation date.

Please consider subscribing to Participant Readiness, Market Notices, Information Technology (IT) Notices, and MIS Report Issues to receive notices posted to the ISO calendar for future projects.

Participant Training Opportunities

The ISO conducted online training for affected customers to learn about changes and ask questions in advance of project implementation. Please consider subscribing to ISO Training to receive notices posted to the ISO calendar for future projects.
