The US Department of Energy (DOE) has announced US$1.5bn in public funding for four major power transmission projects. It will enable 1,000 miles (1,610 km) of new transmission development and 7,100 MW of new capacity throughout Louisiana, Maine, Mississippi, New Mexico, Oklahoma. Projects include:
-
a 111-mile (179 km) transmission line (Aroostook Renewable Project) with a capacity of 1.2 GW connecting a new substation in Haynesville, Maine, to Independent System Operator-New England (ISO-NE) system at a substation in Pittsfield, Maine, worth US$425m;
-
a 400-mile (644 km) 1.9 GW high-voltage direct-current (HVDC) transmission line (Cimarron Link) from Texas County, Oklahoma to Tulsa, Oklahoma, worth US$306m;
-
a 320-mile (515 km) HVDC line (Southern Spirit) liking the Electric Reliability Council of Texas (ERCOT) grid for the first time with electric grids in the southeastern US power markets with a capacity of 3 GW, worth US$360m (the new line should prevent outages during extreme weather events);
-
a 108-mile (174 km) transmission line (Southline) delivering 1 GW of capacity between Hidalgo County, New Mexico and Las Cruces, New Mexico, with up to US$352m potential contract value.
