A massive winter storm is continuing to hit the eastern United States, bringing dangerous ice and freezing rain. The storm has left more than a million customers across multiple states without power. Tennessee, Mississippi, Louisiana and other Southern states have been particularly hard hit, and officials warned that outages could persist for days or longer.
The storm’s immediate effects include downed power lines and interruptions to electricity service for a large number of customers. Freezing rain and ice make trees and branches heavy, which can damage above-ground electrical equipment. Local resources for repair and restoration have been stretched by the scale of the damage, and it is not yet clear how long full restoration will take.
Sara Eftekharnejad, an associate professor at Syracuse University, studies power system stability, reliability and the integration of renewable energy into electrical grids. Experts are using events like this storm to consider how to improve grid reliability and how renewable sources interact with overall grid stability.
