The ERCOT Queue by Fuel and IA Status

A reference snapshot of the ERCOT interconnection queue as of the June 2026 GIS report, split by technology and by interconnection agreement status.

The queue totals 434 GW across 1,828 active projects. Of that, 134 GW, about 31 percent, carries a signed interconnection agreement. The gross number and the committed number tell opposite stories: the headline suggests oversupply, while the committed subset shows how much thinner the deliverable stack is.

Batteries lead the queue at 162.6 GW, but only 37.4 GW is signed. Solar is 151.6 GW with 63.3 GW signed. Gas is 69.7 GW with 14.6 GW signed, the lowest committed share of the four. Wind is 47.1 GW with 18.7 GW signed.

The pattern to carry forward: signed interconnection agreements, not gross queue capacity, are the supply curve that matters for pricing. Gas, the firm resource, has the widest gap between what is queued and what is committed.

Methodology

Figures are drawn from the ERCOT June 2026 GIS Report (Large and Small Gen, projects with a Full Interconnection Study requested) and reconciled against the source file before publication. "Signed IA" reflects the report's IA Signed field. Figures reflect the June 2026 snapshot and may have changed since.
