REWIRE Act
This bill, known as the REWIRE Act, would streamline the process for upgrading power lines by exempting certain transmission upgrades from detailed environmental reviews when they occur within existing rights-of-way. It specifically allows utilities to replace or upgrade conductors and install new grid technologies without preparing environmental impact statements, provided the work stays within previously disturbed land or current corridors. The legislation also directs the Federal Energy Regulatory Commission to create rules that improve financial returns for companies investing in advanced transmission materials like carbon fiber cables. Additionally, the bill establishes a federal modeling program to better predict grid performance and creates a technical assistance clearinghouse to help utilities implement these new technologies.
