GI Queue Related Documents

The Generator Interconnection Process (GI) defines the steps an interconnection customer and MISO take to move interconnection requests through the interconnection queue. The process can result in an interconnection agreement that allows the customer to connect generation to the MISO grid.

Generator Interconnection Queue – Active Projects Map: Provides an interactive view of projects by fuel type, development cycle, or summer/winter net production.

Interactive Queue: Allows users to filter the interconnection queue by status, fuel type, and/or state. You can also download the complete interconnection queue spreadsheet from this page.

GIQ Web Overview: Updated monthly, this document provides a number key data points regarding the current active interconnection queue.

MISO Generation Interconnection Business Practice Manual BPM-015: Provides the most current information relating to the generation interconnection process.

MISO Points of Interconnection (POI) Tool: Helps Interconnection Customers pre-screen for potential constraints associated with existing POIs.

MISO Study Metrics: Updated quarterly, provides a number of key data points regarding the MISO ongoing Generator Interconnection DPP schedule. 

Note: MISO cannot publicly disclose specific project details until the Generator Interconnection Agreement is filed with FERC. 

The process incorporates interaction between generator Interconnection Customers (ICs) and MISO and uses milestone achievements as a method of moving Interconnection Requests (IRs) through the queue. Milestones (represented by black diamonds in the diagram) serve as control checkpoints where MISO assesses IRs based on pre-defined criteria. Milestone achievement is a key determinant in how an IR is progressing through the process. Milestones may be technical (such as a stability model) or business-related (such as proof of Site Control). The overall process is outlined in the process flow diagram.

1. Pre-Queue: Includes an overview of the process, timeline, and expectations pertaining to the output of the Generator Interconnection process. The Pre-Queue Phase provides interested parties with regular information sessions to ensure the customer is well informed about the queue process and requirements in every phase of the process. Customers are able to submit an application at the end of this phase. Interconnection Customers also have the option to discuss potential projects with MISO and the associated Transmission Owner by requesting ad hoc sessions.

Note: GIQ applications are accepted in alignment with the existing Study Cycle. Applications received after the posted Study Cycle deadline are assigned to the next Study Cycle. MISO charges a flat non-refundable D1 application fee (currently, $5,000 in 2022).  Additionally, a D2 deposit is required to fund the three DPP System Impact Studies and Facilities Study. 

An M2 Milestone of $4,000 per MW studied (cash or irrevocable letter of credit) is also required at the time of application submission.

2. Application Review: The application cannot enter the generator interconnection queue until all identified deficiencies have been cleared. During this phase, MISO reviews the request, checks customer readiness, and conducts a mandatory scoping meeting. Validated applications will receive a project number that begins with the letter “J” (JXXXX).

3. Definitive Planning: 

DPP Phase 1: Designed to provide the IC with a preliminary detailed analysis of their IR’s impact on the reliability of the Transmission System.

DPP Phase 2: Designed to provide the IC a revised and detailed analysis of their Interconnection Project’s impact on the reliability of the Transmission System after incorporating updated generation assumptions resulting from the withdrawal of interconnection requests during DPP 1.

DPP Phase 3: Designed to provide ICs a final, detailed analysis of their Interconnection Project’s impact on the reliability of the Transmission System after incorporating updated generation assumptions due to potential withdrawal of interconnection requests during DPP 2.

Upon completion of the DPP, the parties enter into final negotiations to create the Generator Interconnection Agreement (GIA). Once an agreement is reached, MISO files the agreement with FERC.

Note: Fees and other information change over time. Refer to BPM-015 for the most current information.
