With growing risks to the nation’s electrical grid from natural disasters and as a potential target for malicious attacks, the U.S. Department of Energy (DOE) and the U.S. Department of Homeland Security (DHS) should work closely with utility operators and other stakeholders to improve cyber and physical security and resilience, says a new congressionally mandated report by the National Academies of Sciences, Engineering, and Medicine.
The grid remains vulnerable to diverse threats that can potentially cause extensive damage and result in large-area, prolonged outages that could cost billions of dollars and cause loss of life, the report found. The committee that conducted the study and wrote the report recommended ways to make the grid more resilient through the development and demonstration of technologies and organizational strategies that minimize the likelihood that outages will happen, reduce the impacts and speed recovery if they do, all the while developing mechanisms for continual improvements based on changing threats.
