U.S. Launches Grain Belt Express, Nation’s Largest Transmission Line

The Grain Belt Express, developed by Invenergy, is poised to become the largest electric transmission project in U.S. history. This 800-mile high-voltage direct current (HVDC) transmission line will traverse Kansas, Missouri, Illinois, and Indiana, delivering 5,000 megawatts of energy—enough to power approximately 3.2 million homes. The project aims to enhance grid reliability, unlock access to affordable clean energy, and provide an estimated $52 billion in energy cost savings to Americans over 15 years.
