The U.S. Department of Energy (DOE) has announced a $1.5 billion investment in four transmission projects designed to improve grid reliability and resilience across six states. Supported by the Bipartisan Infrastructure Law and managed by the Grid Deployment Office (GDO), these projects will enable nearly 1,000 miles of new transmission development, adding 7,100 MW of capacity in Louisiana, Maine, Mississippi, New Mexico, Oklahoma, and Texas. In addition to enhancing grid resilience, the projects are expected to create approximately 9,000 jobs.

The projects include:

• Aroostook Renewable Project in Maine, which will build a 111-mile transmission line to connect renewable energy in northern Maine to the Independent System Operator-New England (ISO-NE) grid. The project will generate 1,200 MW of new capacity and create over 4,200 construction jobs.

• Cimarron Link, a 400-mile high-voltage direct current (HVDC) line in Oklahoma, will transmit 1,900 MW of wind and solar power to growing load centers. This project will create more than 3,600 construction jobs.

• Southern Spirit, a 320-mile HVDC line across Texas, Louisiana, and Mississippi, will provide 3,000 MW of bidirectional capacity, enhancing grid reliability between regions. It will create 850 construction jobs and 305 permanent jobs.

• Southline, a 108-mile line in New Mexico, will add 1,000 MW of bidirectional capacity. It will support industries like semiconductor and battery manufacturing while creating at least 150 new construction jobs.

These investments are part of the Transmission Facilitation Program (TFP), which aims to alleviate financial barriers to transmission development. The DOE also released the National Transmission Planning (NTP) study, which outlines pathways to expand transmission capacity by up to three times the 2020 level by 2050, potentially saving up to $490 billion.
