ERCOT Queue Chartbook, April 2026

The ERCOT Queue Chartbook has been refreshed. Changes this month:

Chartbook expanded to 17 charts. New this month: ERCOT reserve margin by CDR vintage, battery fleet by duration, GE Vernova gas turbine backlog, Peaker Net Margin history, TEF approvals vs LTSA need, thermal fleet age, retirements pipeline, hyperscaler power commitments, and PJM cleared reserve margin vs target.

PJM section now shows the 2027/28 BRA shortfall: the first delivery year where the entire RTO cleared below the reliability requirement, by 6,517 MW UCAP.

New methodology page at /methodology documenting all data sources, refresh cadence, and editorial voice discipline.
