Autoresearch: CEG PJM co-location framework, front-of-meter shift, and the June 30 Calpine lockup

Summary

The biggest update is a framing reversal vs. the 06-08 dispatch, which treated "FERC RM26-4 likely a NOPR + behind-the-meter (BTM) co-location blocked" as a CEG overhang. CEG CEO Joe Dominguez has pivoted Constellation to front-of-the-meter ("on-grid") co-location and stated CEG does not need BTM to achieve compelling pricing (power-eng). That reduces the weight of the RM26-4/BTM overhang on CEG specifically — the regulatory delay still slows the industry's BTM model, but CEG's actual chain (front-of-meter nuclear PPAs, proven via the Microsoft/Three Mile Island deal, restart 2027) does not depend on it. Separately, the PJM co-location rules are a distinct, further-along proceeding (CEG's own Section 206 complaint, Docket EL25-20) from the generic RM26-4 rulemaking. And the June 30 Calpine lockup overhang is being actively managed — an 11M-share secondary already closed June 1-2.

Findings

CEG has shifted to front-of-the-meter — the BTM block matters less to CEG than to the industry

CEO Joe Dominguez: "Locating AI facilities proximate to large, clean and reliable power plants continues to make all the sense in the world. But, critically, we do not need to have load co-located or behind-the-meter for us to achieve compelling pricing" (power-eng). Drivers of the shift: (1) regulatory uncertainty on BTM co-location following the AWS–Talen deal rejection; (2) BTM requires local-utility cooperation that "hasn't happened easily"; (3) the Microsoft PPA to reopen Three Mile Island Unit 1 is cited as proof that front-of-the-meter deals deliver competitive economics (power-eng). The TMI restart is now expected 2027, accelerated by a recent FERC CIR waiver (power-eng).

Thesis implication: the 06-08 conviction cut (0.70→0.65) was driven by "BTM blocked + RM26-4 → NOPR." This source says CEG's economics don't hinge on BTM — so the BTM-block portion of that overhang is partly mooted for CEG (it remains a drag on pure-BTM plays like the rejected AWS–Talen structure). The front-of-meter PPA model is the durable chain.

The PJM co-location track (Docket EL25-20) is distinct from RM26-4 — and further along

CEG filed a Section 206 complaint (Docket EL25-20) asking FERC to fix PJM's lack of clear rules for interconnected generators providing BTM service to isolated co-located load (DCD). On Dec 18, 2025, FERC issued an order on the show-cause proceeding — granted in part / denied in part, found PJM's co-location/BTMG tariff "unjust & unreasonable," and established a paper-hearing process; PJM's initial brief was due 2/16/2026 (GDS Associates, White & Case). So the PJM-specific co-location framework is its own proceeding with briefing already complete — not the same thing as the generic RM26-4 rulemaking acting end-June.

RM26-4 end-June action: still ambiguous on instrument (NOPR vs. rule)

FERC's April 16, 2026 "Order Regarding Intent to Act" commits to acting by end of June 2026, "quick, efficient and legally durable" (FERC news, Troutman). The April order does not specify whether the June action is a final rule, a NOPR, or another instrument — legal analysts note the announcement "intentionally defers substantive details" (Holland & Knight). The ANOPR (initiated Oct 23, 2025 on DOE directive) defines large loads as >20 MW and asks whether flexible/curtailable co-located loads can clear interconnection studies faster (possibly within 60 days); FERC has directed PJM to adopt transparent rules for large loads co-located with generation (FERC RM26-4). So the 06-08 "likely NOPR (12–18mo delay)" read is not confirmed by these sources — the instrument is genuinely undetermined; "legally durable" could cut either way.

Calpine lockup (June 30): overhang being actively worked through

The Calpine deal closed Jan 7, 2026 (cash-and-stock; 50M newly issued CEG shares; registration rights; staged lockup ending 2027) (Globe & Mail). A lockup on ~25M Calpine-related shares expires June 30, 2026 — a potential near-term supply/selling-pressure event. But CEG has already started clearing it: on June 1, 2026 CEG entered an underwriting agreement for selling shareholders to sell 11,000,000 shares, closing June 2 (lockup waived solely for those Calpine-origin shares) (TipRanks). So part of the overhang is being absorbed via orderly secondary placement rather than hitting all at once on June 30.

Contradictions and open questions

• RM26-4 instrument unresolved. 06-08 read it as "likely NOPR (delay)"; these sources say the instrument is undetermined ("legally durable" language). The end-June action itself is the resolution — watch the docket.
• How much does front-of-meter fully insulate CEG? Dominguez says BTM isn't needed for compelling pricing, but front-of-meter deals still depend on PJM interconnection queue treatment and capacity pricing — which RM26-4/EL25-20 also touch. The insulation is partial, not total.
• June 30 residual supply. ~25M-share tranche minus the 11M already placed — is the remaining ~14M still locked, or does June 30 free the full 25M? The staged-lockup-to-2027 structure suggests tranches; exact remaining float at June 30 is unconfirmed here.

Provenance

Rounds run: 2 of 3 (early-exit — the front-of-meter pivot answered the core question; round 3 would not have materially changed the synthesis).

Sub-questions by round:

Round 1 (broad survey):

1. Has CEG/PJM filed or signaled a behind-the-meter co-location framework in June 2026? Timeline?
2. FERC RM26-4 status — NOPR vs. final rule, end-June 2026 timing?
3. Calpine lockup expiring June 30 2026 — share-unlock mechanics and CEG deal status?

Round 2 (drill-down):

1. What exactly will FERC's end-June RM26-4 action be (final rule vs. NOPR)? — targeted the instrument ambiguity.
2. CEG's current position on BTM vs front-of-the-meter co-location? — targeted whether the BTM block is actually a CEG overhang.
