On December 16, 2024, the U.S. Department of Energy (DOE) released a list of three potential NIETCs moving to the next phase of the designation process. A NIETC is an area of the country where DOE has determined the lack of adequate transmission harms consumers and the development of transmission would advance important national interests in that area, such as increased reliability and reduced consumer costs. DOE recently established a four-phase process for NIETC designation; the potential NIETCs moving to Phase 3 of the designation process are:
- Lake Erie-Canada Corridor, including parts of Lake Erie and Pennsylvania
- Southwestern Grid Connector Corridor, including parts of Colorado, New Mexico, and a small portion of western Oklahoma
- Tribal Energy Access Corridor, including central parts of North Dakota, South Dakota, Nebraska, and five Tribal Reservations
