Pacific Northwest National Laboratory Creates New Resilience Analysis Tool for Grid Recovery

DOE’s Pacific Northwest National Laboratory (PNNL) recently developed the Recovery Simulator and Analysis (RSA) tool, which simulates the time and effort needed for the grid to recover from severe damage, helping organizations in Puerto Rico better prepare for hurricanes.

In preliminary analysis, the Recovery Simulator and Analysis (RSA) tool ran simulations of 100 hurricane recoveries and found that smaller sized and more distributed future generation could cut the transmission recovery effort — work crew days — by approximately 25 percent. Identifying where load is recovered last, especially in a long recovery such as Hurricane Maria, may be helpful in determining where grid investments would be most beneficial for restoring power to critical services after a disaster. This tool directly supports the Puerto Rico Grid Resilience and Transitions to 100% Renewable Energy Study (PR100), a two-year effort by GDO and six national laboratories to comprehensively analyze stakeholder-driven pathways to help the government of Puerto Rico reach its goal of 100% renewable energy by 2050.
