A public index of the projects reshaping the Texas grid: the largest 765 kV transmission builds and the largest data-center and large-load campuses now under way. Every figure sourced and dated. Freely available, no registration required.
This index ranks the largest active projects in two categories, transmission and large-load, most significant first. It is a public companion to the Churchill Hughes gated intelligence library, which sets out the compensation, hiring demand and talent-supply detail behind these headlines.
Transmission costs and mileage are anchored to ERCOT planning documents, PUCT filings and sponsor-utility releases; several 765 kV segments have public endpoints but no disclosed line-level cost. Large-load capacities are developer-announced full-build-out figures, and actual energised megawatts are usually a fraction of the headline. The ~226-474 GW queue figures are gross interconnection requests, not committed load.

AI-campus plans move fast and some slip: the 2 GW Poolside / CoreWeave West Texas project, widely reported in 2025, had its anchor contract terminated in 2026. Headline megawatts are announcements, not energised load, which is exactly why sequencing the real build matters. Since August 2026 a state audit has paused new ERCOT data-center approvals, and the newest giants (Microsoft and Amazon in Pecos) are building their own gas generation.

Every project in this index is delivered by people: interconnection and studies engineers, transmission line and substation designers, protection & control specialists, commissioning engineers, and the project directors who lead them. They are in the shortest supply of the entire build-out.
Churchill Hughes is a focused executive search firm for senior leadership across the ERCOT transmission and power-infrastructure build-out: grid interconnection, transmission, substations, protection & control, commissioning, power delivery and BESS. Every figure in this report is drawn from the same market intelligence we use on live searches.
The gated Churchill Hughes intelligence library goes behind this index: compensation benchmarks by role and seniority, the interconnection and large-load queue detail, the transmission and substation build, BESS economics, and the talent-supply squeeze across each. One registration unlocks all of it.
To discuss any figure in this report, benchmark a role you are hiring for, or pressure-test an offer before it goes out, contact James Hughes at office@churchillhughes.com. The conversation is free. The hiring mistakes it prevents usually are not.
