1. Short title This Act may be cited as the Grid Resiliency Tax Credit.

2. Findings Congress finds the following: A robust electric power transmission system is critical to the economic, energy, and national security of the United States. The electric grid faces challenges from aging infrastructure and a need for increased electric power transmission capacity. The United States faces a pressing need to expand electric power transmission. Electric power transmission investments will— improve resilience by enabling access to diverse generation resources across the country; promote economic benefits and create new jobs in communities across the country; and enhance electric grid reliability.
