What version of the Attachment X Appendix 1 form should be used?
The online application tool will automatically create an Appendix 1 when the project is validated.

To add batteries to an existing project, would MISO recommend surplus interconnection services or a new queue position? Does surplus prohibit grid charging?
If the storage has not additional injection to an existing request, it sounds like you are asking for a 0 MW request. This is a situation where the primary fuel will cap any injection and the BESS is only supplementing the primary fuel. If you are planning on the BESS to be a 0 MW Net at the POI (coupled with your primary fuel), you should use the Surplus process to add any storage to that project once Decision Point II is over for that primary fuel project. MISO believes the best way to submit and study your 0 MW net injection requests is to submit these as Surplus Interconnection requests at the conclusion of the associated Decision Point IIs. This is specifically one of the reasons changes were made to Attachment X tariff in 2022 to the Surplus process so that they could be studied properly.

Can corresponding steady state and dynamic models be submitted in PSS/e version 34 or is only PSS/e version 35 accepted?
MISO prefers V35; but V34 is acceptable.

For NRIS only requests, are all technical fields required, or can some fields be skipped? If the request is for an existing unit, does section A, B, and C still need to be filled out?
Complete submission is required.

What should I select in the application if my POI isn’t listed?
If you are unable to find the substation in the existing TTF listing, please use the "Other" option in the POI section of the online application tool and note the POI and what related MTEP Appendix A project number it is related to.

The Interconnection Application asks for 'Transmission Line Names.'  The ITC METC 'Transferred Transmission Facilities' spreadsheets on the MISO website have blank columns for Transmission Line Names. Can a description of the transmission line location be entered in this field instead of a name?
Interconnection Customers should use the end points of the Transmission Line, which can be entered after selecting “Other.”

What is MISO's recommendation if a vendor provides refined PSSE models after initial IR submittal?  Can models be updated before DPP 1 starts? What about after DPP 1 before beginning of DPP 2?
Before kick-off yes, but afterwards must be submitted as a material modification. Please coordinate with MISO to determine the necessity of a material modification.

If a PSCAD model is required, when will we be notified and when will it need to be submitted?
All inverter-based resources are required to submit a PSCAD model.  During the Phase 1 kick-off meeting for each DPP cycle, MISO will provide a list of projects which must submit a PSCAD model and the deadline by which MISO must receive the submission.  PSCAD models may be uploaded via the application portal.  Please see BPM-015, section 5.2.3.1 for PSCAD requirements.

For information about payments, refer to the GI Finance FAQ.

For information about Site Control, refer to the Site Control Submission Checklist.

Does MISO differentiate fuel type when performing NRIS deliverability analysis?
All units under study are dispatched to their full NRIS request amount, regardless of fuel type, per section 6.1.1.1.9 of MISO’s BPM-015.

Will cluster participants be notified when the screening analysis is published?
All active interconnection requests will receive notification when the screening study is posted on the MISO Extranet.

Where can I view a walkthrough of the GIA portal?
Please review the queue process workshop recording and refer to the GI training guides available in the Learning Center.
