This past winter saw energy grids face a range of severe weather threats. Ice storms, plummeting temperatures, high winds, and flooding caused grid-infrastructure damage and resulted in millions of customers facing supply disruption. In response, a number of initiatives, both at the federal and state level in the U.S. as well as internationally, were introduced. Some processes are new, based on a better understanding of the threats, and strengthen utilities’ ability to act. Others are further developments in processes already underway to enhance protection and harden the grids. Overall, experiences this winter reinforced the challenges posed by climate change and the importance of an enhanced focus on grid reliability and resilience.
