NRECA worked with Los Alamos National Laboratory (LANL) and Pacific Northwest National Laboratory (PNNL) to develop an Optimal Resiliency Model software tool called “LPNORM.” This new tool, available on NRECA’s Open Modeling Framework (, allows users to import distribution circuit and pole models, model damage from extreme weather events, input resilience criteria, and generate optimal design solutions to improve the resilience of the system.
