MISO ran an August Generator Interconnection Queue Process Workshop focused on How to use the new Generator Interconnection Application (GIA) portal, key queue cap mechanics and deadlines, and nuts-and-bolts readiness items like site control documentation, fee timing, and agreement workflows. Here’s our thorough overview.
New GIA portal (Help Center)
MISO walked through the new GIA portal (in the MISO Help Center), noting an ongoing data migration from the legacy Grid Unity portal. Until migration is complete, historical applications remain in the old portal, but all new applications must be submitted in the new one. The deck also highlighted practical enhancements: collaborative editing by adding team contacts, section-by-section navigation, and auto logout/resume behavior. Links to step-by-step access and user-type setup were provided.

Queue Cap: how it works
Starting with DPP-2025, MISO’s Queue Cap limits the total capacity studied each cycle to 50% of non-coincident peak load per study region, with a public Queue Cap Tracker to monitor applications versus regional caps. The workshop flagged the tracker and the companion FAQ for ongoing updates.
Key date flagged in the deck
The workshop materials listed a DPP-2025 application deadline of Oct 7, 2025 (5:00 p.m. ET), with all submissions, payments, and site-control evidence due by the deadline.
Site control & documentation (what “ready” means)
MISO reiterated timing requirements and acceptable evidence. Highlights:
- At Application: 100% site control for the generating facility; 50% for the tie line or $80k/mile deposit.
- At DP-II: 100% facility site control; 50% tie-line and 50% switchyard.
- At GIA: 100% across facility, tie-line, switchyard, and applicable TO facilities/NU at POI.
- Acceptable documents include leases/options/deeds with GIS maps and MISO’s tariff affidavit; non-binding LOIs/MOUs are not accepted.
Submittal, review & signatures
The deck covered application review/correction cycles, deposit timing (e.g., milestone deposits and automatic withdrawal penalties), and DocuSign for executing application documents once a J-number is assigned. MISO Energy
Studies, modeling & agreements
MISO refreshed DPP cluster study flow (SIS to Facilities Studies), affected-system coordination, and where PSCAD models are required (e.g., Ameren, Entergy, ATC, ITC Midwest/MRES regions; otherwise by GIA execution for IBR projects). It also walked through negotiations and agreement tooling (ShareFile collaboration), plus material-modification protocol and fees.
ERAS context (fast-track path)
Given July’s FERC approval, MISO reiterated the Expedited Resource Addition Study (ERAS), a temporary fast-track for capacity/reliability-critical projects, with the first window Aug 6–11 and the first quarterly study starting Sept 2; ERAS runs no later than Aug 31, 2027.
Why this matters (developer takeaways)
- Portal shift = fewer admin stalls. New access, collaboration, and resume features should reduce back-and-forth and cut avoidable errors in submittals.
- Cap discipline = earlier certainty. With regional caps and a public tracker, timing and completeness now directly affect study eligibility—treat the cap like a hard gate.
- Documentation is destiny. Site control and required uploads are non-negotiable; non-binding docs won’t fly and could push you past deadlines.
- ERAS ≠ business as usual. The window is short, slots are limited, and first-come processing plus quarterly studies favor fully prepped packages.
ZEG Takeaways
Queue speed now hinges on operational readiness as much as siting: correct portal setup, airtight site control, and disciplined filing against cap windows.
