Interconnecting the Texas Grid
The Southern Spirit HVDC line is a federally backed project, receiving $1.5B from the US Department of Energy (DOE) (simulated late 2025 context), specifically designed to connect Texas's isolated ERCOT grid with the neighboring Southeast grid. This interconnection is a massive deal, boosting reliability and preventing future failures like Winter Storm Uri. Given the high-priority federal funding, the project's high political visibility, and the strong incentive from Louisiana and Mississippi to improve resilience, the 320-mile line is strongly favored to be fully operational by the end of 2028, despite the historically long lead times for transmission projects.
