Autoresearch: CEG FERC CIR Waiver and RM26-4-000 Rulemaking — June 2026
FERC granted CEG 760 MW CIR transfer waiver June 2 (TMI restart → 2027 vs 2031 prior); FERC committed to RM26-4-000 large-load interconnection order by end-June 2026; Amazon Calvert Cliffs deal in exploration; mechanism thesis advancing on multiple fronts.

Summary
Two catalysts are converging for the CEG nuclear-baseload and FERC CIR waiver mechanisms. First: on June 2, 2026, FERC granted Constellation Energy a waiver allowing the transfer of 760 MW of Capacity Interconnection Rights from its Eddystone gas plant to the Crane Clean Energy Center (Three Mile Island Unit 1 restart), pulling the restart timeline to 2027 from the prior 2031 estimate — directly serving Microsoft data centers. This is the first large-scale FERC CIR transfer under the new co-location framework. Second: FERC committed on April 16, 2026 to act on Docket RM26-4-000 (large-load interconnection rulemaking) by end of June 2026, establishing formal standards for integrating large loads (>20 MW, primarily data centers) into the transmission system. The end-June ruling is an imminent dated catalyst that will either validate or constrain the co-location/CIR-waiver mechanism. A potential Amazon deal at Calvert Cliffs (2,000 acres under exploration) is unconfirmed but represents an additional upside signal.
Findings
CEG FERC CIR Waiver — June 2, 2026
Three days ago, FERC issued a waiver approving Constellation Energy's transfer of 760 MW of Capacity Interconnection Rights from the Eddystone natural gas-fired plant near Philadelphia to the Crane Clean Energy Center site (Three Mile Island Unit 1 restart in Pennsylvania) (Gurufocus; ZeroHedge).
Key implications:
- The waiver allowed transfer of existing CIRs rather than requiring TMI to go through the multi-year interconnection queue from scratch — the precise mechanism the thesis identified as a structural advantage for nuclear restarts over new-build generation
- Restart timeline accelerated from 2031 → 2027 — a four-year pull-forward enabled by the CIR transfer
- Primary customer: Microsoft (data centers) — the TMI restart was initiated under a power purchase agreement to serve Microsoft's AI compute demand
- Exploring: Amazon (unconfirmed) at Calvert Cliffs nuclear station — reports of 2,000 acres in site evaluation (no binding deal)
- CEG stock +2.6% on the day of the announcement
Mechanism validation: This is the first major real-world demonstration that the FERC CIR transfer mechanism works at scale for nuclear-data center co-location. The Eddystone→Crane transfer is not a generic precedent — it required the specific regulatory circumstance of retiring gas capacity at the same operator having transferable CIRs. But it proves the mechanism is executable, not just theoretical.
FERC RM26-4-000 — Rulemaking Status and June 2026 Catalyst
Background: The U.S. Secretary of Energy (under DOE Organization Act § 403) directed FERC in October 2025 to initiate an Advance Notice of Proposed Rulemaking on timely, orderly integration of large loads (defined as >20 MW demand) into the interstate transmission system. Docket RM26-4-000. (FERC.gov RM26-4; Holland & Knight)
April 16, 2026: FERC issued "Order Regarding Intent to Act" — formal commitment to take action by end of June 2026, with language that the action will be "quick, efficient and legally durable." This is the dated catalyst that makes June 2026 a binary event for the regulatory framework.
Prior precedent actions FERC has already taken:
- December 2025: Ordered PJM Interconnection to implement transparent co-location rules for loads co-located with generation
- January 2026: Approved Southwest Power Pool's "High Impact Large Load" (HILL) assessment initiative
What June action likely covers: Standards for processing large-load interconnection requests — cost allocation, study timelines, queue positioning, treatment of co-located generation. The regulatory form (final rule vs. NOPR) was not specified in the April commitment. A NOPR would open another comment period (6–12 months before final rule); a final rule or interim rule would be immediately actionable.
Stakes for the mechanism:
- If FERC issues a favorable final rule: immediately validates and scales the co-location pathway for nuclear + data centers — positive for CEG, VST, NRG, and grid infrastructure plays
- If FERC issues a NOPR: delays certainty but signals regulatory direction (still positive for the thesis medium-term)
- If FERC's order creates new cost-allocation burdens or queue requirements for co-located loads: headwind for the nuclear-data center deal flow
Timeline: End of June 2026 — within the next 25 days.
Open Questions
- Amazon/Calvert Cliffs: Is this a real deal in negotiation or speculative? Calvert Cliffs is a 1,700 MW nuclear plant in Maryland. An Amazon PPA at Calvert Cliffs would be a second major Microsoft-scale deal for CEG and would significantly derisk the valuation.
- RM26-4-000 form: NOPR or final rule? The "legally durable" language in FERC's April 16 commitment suggests they want something that survives judicial challenge — which may mean a NOPR is more likely than a rushed final rule. Watch the June docket filing.
- Other nuclear operators: Is the Eddystone→Crane CIR transfer a template other operators can replicate? Which operators have retiring gas capacity with transferable CIRs co-located near nuclear plants? (PSE&G / PSEG Nuclear; Exelon; Entergy candidates)
