The US Department of Energy (DOE) has pledged $1.5 billion to improve the country’s power grid infrastructure, funding four transmission projects that will add nearly 1,000 miles of new lines and 7.1GW of capacity. The investment aims to enhance grid reliability and support renewable energy integration.
The projects include the Aroostook Renewable Project in Maine, featuring a 111-mile transmission line capable of handling 1.2GW, and the Cimarron Link in Oklahoma, establishing a 400-mile HV DC line to transmit 1.9GW from wind and solar sources. The Southern Spirit line will connect the ERCOT grid to southeastern US markets with 3GW of bidirectional capacity, while the Southline Project’s second phase in New Mexico will add 108 miles and 1GW of capacity.
