Preventing Power Outages Act

This bill amends the Infrastructure Investment and Jobs Act to change how federal grants for grid resilience are awarded. It requires the Department of Energy and states/tribes to give priority to entities with higher historical outage metrics (measured by SAIDI, SAIFI, and CAIDI scores), meaning areas with more frequent or longer power outages receive greater consideration for funding. The bill does not create new programs but modifies existing grant criteria to prioritize communities with poorer grid reliability. It also clarifies that grant applications addressing multiple grid improvement types cannot be penalized or given preference solely for doing so. The changes apply to grants funded through the program, with adjusted funding availability periods.
