– **Generation System Reliability**: Metrics include Loss of Load Probability (LOLP), Loss of Load Expectation (LOLE), Expected Power Not Supplied (EPNS), and Energy Index of Reliability (EIR). Initially, two of these metrics will be selected based on the progress and specific requirements of the study.
