Near-Term Reliability and Resilience

This final report documents the Near-Term Reliability and Resilience (NTRR) project, a multi-laboratory effort examining how changes expected over roughly the next decade could affect the reliability and resilience of the U.S. electricity system and the natural-gas infrastructure on which much of the power system depends. The work brings together electric-grid and natural-gas modeling, scenario analysis, and resilience metrics so that stresses such as extreme weather, fuel-supply disruptions, and evolving generation and policy conditions can be evaluated in a coordinated way rather than as isolated sector problems. A central theme is the growing interdependence between gas transportation and electricity generation and the need for analysis methods capable of representing those cross-sector effects. The project also establishes a common analytical framework for comparing system performance across regions and scenarios and for identifying where existing modeling, data, and computational capabilities need improvement. Overall, the report provides an integrated foundation for assessing near-term infrastructure risk and for supporting planning decisions intended to preserve reliable energy delivery as the system evolves.
