Beginning in the late 1990s, electricity markets in many US states
were deregulated, and almost half of the nation's 103 nuclear power reactors were sold to independent power producers. Deregulation has been accompanied by substantial market consolidation, and today the three largest companies control one-third of US nuclear capacity. We find that deregulation and consolidation are associated with a 10 percent increase in operating performance, achieved primarily by reducing the duration of reactor outages. At average wholesale
prices, this increased operating performance is worth $2.5 billion annually and implies an annual decrease of 35 million tons of carbon dioxide emissions. (JEL L11, L51, L94, L98, Q42, Q48)
