Per NERC Standard FAC-001-3 requirement R3.3, each Transmission Owner shall have procedures for confirming that their new or materially modified transmission facilities are within a Balancing Authority Area’s metered boundaries. Obligations for interconnections related to transmission are described in Appendix B to the Transmission Owner’s Agreement. Evidence of new generation can be supplied through the MISO Transmission Expansion Planning (MTEP) process by the Transmission Owner(s). See Attachment FF II.A.2; TOA Appendix B Section VI. A copy of the interconnection or location of interconnection within metered boundaries is provided in MISO Tariff Attachment WW.

Distribution (Electricity-End-User)-to-Transmission Interconnections are governed by Appendix B of the Transmission Owners Agreement.
The Transmission Owner that receives a request for a Distribution-to-Transmission interconnection, applicable to FAC-002-3 Requirement R1, serves as the designated lead of the joint reliability impact study.
For generator interconnection, the study is identified as the System Impact Study.
MISO and all impacted Transmission Owners support the joint reliability impact study of any Distribution-to-Transmission Interconnection applicable to FAC-002-3 Requirement R1. If the joint reliability impact study identifies necessary network upgrades, they will be “Submitted for Recommendation” through the MISO Transmission Expansion Planning (MTEP) process by the Transmission Owner(s). See Transmission Owners Agreement, Appendix B Section VI.
Network Upgrades identified in the System Impact Study are submitted to MTEP by the Transmission Owner and are placed in Target Appendix A. They are then approved in the next MTEP cycle.
Other general obligations for interconnections are described in the Transmission Owners Agreement and Attachment X of the Tariff.

Transmission Owners submit facility ratings information through the Model on Demand tool for insertion into MISO near-term and long-term models. Transmission Owners may also provide stability limits through participation in studies conducted by our Expansion Planning, Forward Operations, or Real-Time Operations divisions. Additionally, we perform online transmission system studies in real-time which provides stability limits based on current system conditions. Transmission Owners may also verbally communicate temporary rating changes to MISO via the Model on Demand tool or by calling to the Reliability Coordinator or Operations Engineer.

Yes. MISO submits the data under R1.3 through R1.5, if requested, to the regions directly into the Regional portal or other agreed upon means by the parties. MISO requires Market Participants to submit data through the Module-E Capacity Tracking tool. The data is then used to populate the NERC Long-Term Reliability Assessment. As long as Market Participants comply with the Module-E1 requirements, they remain compliant with the MOD-031 standard and may use the LTRA report as evidence of compliance.

The preliminary schedule for providing data is found in MISO MOD-032 Model Data Requirements & Reporting Procedures. MISO sends all model data requests pertaining to MOD-032-1 to MISO’s Planning Subcommittee email distribution list.
To sign up for the Planning Subcommittee email distribution list:
The preferred approach is that the GO submits data to their Transmission Planner (TP) who then provides the data to MISO. If the GO follows this approach, they still are expected to send a MOD-32 Letter of Notice of Data Submittal Duty form to TAMModeling@misoenergy.org
If the TP does not agree to submit the GO data to MISO, the GO must provide their data via the MISO Model on Demand tool. To get access to the Model on Demand please complete the form at: https://cdn.misoenergy.org/Model-On-Demand%20Access%20Request102831.docx

MISO uses SynchroPhasor data to validate its dynamic models. The majority of MISO TOs provide PMU data to MISO in real time. In these cases, MISO as Reliability Coordinator, shares the members’ PMU with our Planning Coordinator staff.
This means TOPs who provide PMU data in real-time to MISO will not receive a data request from MISO. If the member did not receive a MOD-033 data request, M2 allows the TOP to self-attest that this is the case. NERC’s CAN-030 is an acceptable way to self-attest. Finally, the member may want to use the MISO general attestation as supplemental evidence.
Members that don’t stream PMU data to MISO may get data requests. These members should retain the data requests and copies of their transmission to MISO. Similar to above, these members may use CAN-030 to self-attest that if they did not get a data request and may also use the MISO general attestation as supplemental evidence.

Operating Plans comprise a document or set of documents and procedures that explain how entities manage operations, reliability, and constraints. Operating Plans do not include daily studies. For instance, MISO’s Operating Plan is comprised of our Congestion Management Procedure, Op Guides, and T-Notes.
Conversely, an Operational Planning Analysis (OPA) evaluates projected system conditions to assess anticipated and potential operating conditions. MISO’s Next Day Security Analysis reports constitute our next-day OPA.
Under IRO-008-2 R2, MISO takes into consideration any Operating Planning Analysis (OPA) the TOP performs for TOP-002-4 R1. To do this, the Transmission Operator compares their OPA and Operating Plans with MISO’s OPA (i.e. our Next Day Security Analysis report). If there are any exceptions identified, the TOP follows the Transmission Security Planning Procedure TP-OP-011 Section 2.10.4. (MISO Extranet > Reliability Authority > Reliability Coordination > Next-Day Analysis > Transmission Security Planning Procedure)
Per the Transmission Security Planning Procedure, if the TOP identifies any exceptions, they must contact MISO’s Transmission Security Planning group to discuss the exceptions to the Operating Plan; the resolution of which is documented via an email.
In order for MISO, as the Reliability Coordinator, to comply with IRO-008-2 and for Transmission Operators to comply with TOP-002-4, as it relates to coordinating our Operating Plans, MISO and the TOPs exchange the procedures that constitute their Operating Plan.
When sending your TOP Operating Plans, email them to RTOpsCompliance@misoenergy.org with TOP-002 in the subject line. To support your compliance and evidence obligations, the email should summarize or point to MISO’s role in your plans. Be sure to cc yourself for your records.
