Queue management

Following execution of a project’s generator interconnection agreement, it must proceed towards commercial operation. Along the way, the project is required to meet the milestones and obligations established in its agreements. The queue management team is here to assist projects in meeting those milestones, including modification requests, project status updates, and coordination with various stakeholders in their implementation process.

Modification requests

A project may request a modification to its project prior to commercial operation through a Material Modification Assessment Request or after commercial operation through a Post-COD modification request. The project must submit a Modification Requests Form along with the applicable financial deposit, technical data, and supporting documentation necessary for the modifications being requested.
 

Methods of modifications include:

• Material Modification Assessment (MMA) – for projects requesting changes prior to achieving commercial operation
• Post-COD modification - for projects requesting changes after achieving commercial operation
• Permissible Technological Advancement (PTA) – for projects making simple changes
• Construction sequencing

The Interconnection Request Form for Modifications, Repowers, and Conversions is a specific interconnecting request form used for queue management team for modification requests or repower requests.

Transmission plan deliverability transfer

Projects may request to transfer deliverability between generating resources within its own project or from one project to another as long as it meets the established tariff and BPM criteria. The request can be completed as a stand-alone request or as part of a modification request. The project must complete and submit a Transmission Plan Deliverability Transfer Form with such requests.

Repowering

Following the retirement of a generating facility, a project may request to repower for the purposes of retaining its Transmission Plan Deliverability allocation and interconnection service rights. The ISO will need to perform a repower study pursuant to Tariff Section 25 to confirm that “the total capability and electrical characteristics of the Generating Unit will remain substantially unchanged.” The project will need to submit a Repowering Affidavit, an Interconnection Request Form for Modifications, Repowers, and Conversions, a deposit, and technical data and supporting documentation necessary to complete the repower study.

Progressing to commercial operation (project management)

Project status reports

Customers with effective generator interconnection agreements are required to provide a Queue Management Project Status Report as requested by the ISO until the project achieves commercial operation.

Transmission check sheets

Transmission Check sheets are utilized by the Queue Management team to confirm the status of upgrade development and certain factors required for approval of a project’s synchronization or commercial operation. Sheets are sent by the Queue Management Specialists roughly 6 months prior to a project’s synchronization date with follow-ups as needed.
