High Level
At its June 26 public meeting, FERC issued orders requiring
MISO and SPP to submit additional compliance filings under Order Nos.
2023/2023-A. These moves reflect continued urgency to resolve lingering
interconnection backlogs and reliability challenges through clearer procedures
and stakeholder engagement. The directives highlight ongoing tension between
ISO/RTO efforts to streamline queue reforms and FERC’s insistence on enhanced
transparency and fidelity to federal mandates.

FERC Orders Additional Filings from MISO, SPP
FERC, June 26, 2025; White & Case LLP, June 2025; RTO Insider, June 29,
2025
• What happened: FERC issued compliance orders under Dockets ER24-2026
(SPP) and related dockets (MISO) directing both RTOs to refine their
Large/Small Generator Interconnection Procedures (LGIP/SGIP) and agreements.
• Who did it: FERC issued the orders at its June 26, 2025, open meeting.
• Why they did it: To enforce adherence to Order Nos. 2023 and 2023-A,
designed to accelerate study cycles, enforce penalties for delays, and
standardize customer engagement processes.
• Stakeholder views: Chairman Christie’s concurrence reaffirmed the need
for rigorous compliance. MISO was flagged for lacking sufficient penalty
mechanisms; SPP was told to clarify site-control definitions and adjust cluster
study cost allocations. A recent RTO Insider summary noted FERC “told MISO it
needs a few more edits to its queue rules.”
• What happens next: Both ISOs must file updated tariff language or
justifications within 60 days. FERC will then assess compliance before the
reforms are finalized.

What’s the So What?
These directives mark a critical moment in FERC's oversight
of interconnection reform, underscoring the commission’s low tolerance for
half-measures. The next 60 days will be decisive: MISO and SPP not only must
align with federal reforms, but must do so in a way that ensures firm
timelines, consistent stakeholder engagement, and enforceable penalties. If
compliance is deemed insufficient, FERC may initiate further enforcement
measures. Given current queue delays, any lapse risks extending interconnection
timelines and exacerbating resource adequacy concerns across the Midwest.
