The Preventing Power Outages Act aims to improve the reliability and resilience of the electric grid in the United States. Its main objective is to extend an existing program that helps prevent power outages and enhances the overall stability of electricity supply. Key provisions of the Act include the establishment of specific metrics for measuring electricity reliability, such as the Customer Average Interruption Duration Index (CAIDI), the System Average Interruption Duration Index (SAIDI), and the System Average Interruption Frequency Index (SAIFI).
