Experts: Texas-style grid failure unlikely in Arizona
Effects of the extraordinarily severe cold weather that recently hit Texas were made worse by the failure of the state’s electrical power systems. Fulton Schools Professor Vijay Vittal, a power systems engineer, says such a scenario in which extreme weather conditions leave millions of residents without power is unlikely to occur in Arizona. Vittal says power delivery systems in Arizona are interconnected and those in Texas are not, which left electricity providers there without sufficient backup capabilities when the big freeze crippled their facilities. Arizona’s interconnected systems proved their value last summer during a period when power utilities were able to avoid outages and meet demand during extended periods of record heat. The news was also reported by KTAR News in Phoenix. U.S. News and World Report, the Arizona Daily Sun and the Kenosha News (Wisconsin).
