schedule a named mechanism, not a conclusion

4 announced additions totalling 96 kwpm 12in-equiv against a base of 95. Confidence-weighted, that is a 73% expansion. Arriving capacity relieves the scarcity the owner earns on.

coverage

Dated 2026-Q4, 2027-Q4. By confidence: 1 firm, 3 planned. Confidence weights the magnitude rather than filtering — a speculative addition is the part of the pipeline most likely to slip, and hiding it would make the schedule look firmer than it is.

Arguments about this mechanism

None yet. No thesis names this mechanism’s subject, which is a gap in the bank rather than a fact about the mechanism.
