The US plans to provide $1.9 billion in federal funding for 31 projects across 26 states to expand electricity transmission capacity, improve grid reliability, and lower power costs, the Department of Energy said Thursday.
The projects, which will receive a total of $5.25 billion including $3.35 billion in recipient cost-sharing, are projected to improve the power grid serving about 100 million Americans.
The projects will reconductor or rebuild over 1,500 miles of transmission lines and deploy grid-enhancing technologies across about 21,000 miles of transmission infrastructure, making over 23 gigawatts of additional electricity capacity available.
The funding is part of the department's Speed to Power through Accelerated Reconductoring and other Key Advanced Transmission Technology Upgrades, or SPARK, initiative, which is funded through the Grid Resilience and Innovation Partnerships program.
The DoE said the upgrades are also expected to improve grid resilience by reducing wildfire risks, limiting the potential for blackouts and strengthening infrastructure against severe weather.
