3. U.S. refineries have high rates of capacity utilization.<br />

Utilization rates measure the level of output a facility produces relative to that facility’s<br />

capacity. For example, a 100 percent capacity utilization rate would indicate that a factory is<br />

producing at its peak output level. Utilization rates reflect various factors, such as the relative<br />

strength of supply and demand, the ability to perform routine maintenance on the industrial<br />

system, and the amount of entry and capacity expansion that has occurred over time.<br />

Annual average rates of U.S. refinery utilization, based on atmospheric distillation<br />

capacity, have averaged above 90 percent in each year since 1993, when U.S. gasoline<br />

consumption first climbed above the levels of the late 1970s. At times, average domestic<br />

refinery capacity utilization has reached 95.6 percent. 45<br />

U.S. refineries have had utilization rates above 90 percent before – for example, during<br />

the last half of the 1950s and from 1963 to 1973. 46 A variety of factors may contribute to high<br />

utilization rates, such as long run demand increases and lack of new entry. Moreover, several<br />

operational changes in recent years have encouraged higher utilization rates. Increased hardware<br />

reliability, more efficient maintenance procedures, and better-performing catalysts for<br />

downstream processing units have enabled refineries to operate more reliably at sustained rates<br />

of high capacity utilization. 47 One recent survey of refining executives indicated that a<br />

utilization rate of 96 percent is the maximum sustainable level. 48<br />
