“They want to start construction in 2029, and the systems to make sure that data center customers can pay for that just don't exist.”

Assessment

The claim states that NextEra Energy plans to begin construction on the Mid-Atlantic Reliability Line (MidAtlantic Resiliency Link / MARL) in 2029. Official project timelines published by NextEra Energy Transmission as of 2026 designate 'Late 2029' as the scheduled start of construction. Furthermore, in formal regulatory testimony submitted to the Public Service Commission of West Virginia on January 30, 2026, NextEra Energy confirmed a projected construction start date of November 2029 to meet its in-service deadline of December 31, 2031, with matching timelines reflected in applications across Pennsylvania, Maryland, and Virginia.

NextEra Energy Transmission's official MARL project schedule designates 'Late 2029' for the start of construction and 'Late 2031' for project completion.
Formal testimony filed by NextEra Energy with the Public Service Commission of West Virginia on January 30, 2026, specifies construction beginning in November 2029.
Regional Certificate of Public Convenience and Necessity filings across Pennsylvania, Maryland, and Virginia submitted in early 2026 consistently state an intended late 2029 construction commencement.

Allsup: Early opposition makes 2029 Mid-Atlantic transmission target unlikely

“The level of opposition, the force of that opposition at such an early stage, relatively I, I'm less than optimistic, I guess, about this particular project. I do think maybe a lot will depend on what FERC does in this parallel proceeding, but I feel like they…”

NextEra plans 100-mile Mid-Atlantic transmission line across PJM

“It's a planned high voltage transmission line spanning about a 107, I think a little over a hundred miles in PJM. It would run from Southwestern Pennsylvania to Northern Virginia, crossing through Maryland and also a good chunk of West Virginia. It's being dev…”
