The U.S. Division of Vitality (DOE) says it’s committing as much as $1.3 billion to transmission strains crossing six states, enabling 3.5 GW of extra capability to come back on-line within the U.S.
The DOE is getting into into capability contract negotiations with three interregional transmission tasks that can strengthen grid resilience and reliability, allow the addition of extra clear vitality assets to the grid, and convey numerous, clear vitality to extra prospects. Â
The chosen tasks are:
Cross-Tie 500kV Transmission Line (Nevada, Utah): Cross-Tie is a proposed 214-mile, 1,500 MW transmission line connecting current transmission programs in Utah and Nevada to extend transmission capability, enhance grid reliability and resilience, relieve congestion on different key transmission strains, and broaden entry to low-cost renewable vitality throughout the area.
The bidirectional nature of Cross-Tie will enhance switch capabilities within the West, unlocking elevated entry to renewable vitality assets within the area.
Development is predicted to start out in Q1 of 2025.
Southline Transmission Venture (Arizona, New Mexico): Southline is a proposed 175-mile, 748 MW transmission line from Hidalgo County, N.M., to Pima County, Ariz., that can assist unlock renewable vitality improvement in southern New Mexico and ship clear vitality to rising markets in Arizona that at present depend on fossil gasoline era.
The challenge, which is the primary part of an extended line, will make sensible use of current transmission rights of method alongside elements of its route, upgrading growing older transmission services which can be the supply of congestion and constraints within the area.
Development is predicted to start out in Q1 of 2025.
Twin States Clear Vitality Hyperlink (New Hampshire, Vermont): Twin States is a proposed 1,200 MW high-voltage direct present (HVDC) bidirectional line that can broaden the capability of the New England electrical grid and enhance its resiliency, reliability and effectivity by offering entry to wash agency vitality provides in Quebec, Canada.
The bidirectional design of the Twin States line may also permit the New England grid to export energy to Canada when New England is producing extra vitality than it wants to fulfill its personal demand, which is predicted to happen because the offshore wind business in New England expands.
Development is predicted to start out in Q3 or This fall of 2026.
DOE anticipates releasing a second spherical of TFP funding within the first half of 2024 by a request for proposals that will embody a mixture of public-private partnerships, loans, and capability contracts totaling as much as $1 billion.
