There has been relatively little agitation to integrate ERCOT into the national systems, primarily because Texas doesn't really need the help. The state uses more electricity than any other, 44 percent more than runner-up California. Much of this is used by industrial customers such as petrochemical plants and oil refineries. Despite Texas' massive thirst for electricity, ERCOT has been able to provide cheap power with few service hiccups. In fact, Texas electricity is cheaper, per kilowatt hour, than the national average.
