This article estimates the capacity value of concentrating solar power (CSP) plants without thermal energy storage in the southwestern United States. The results show that CSP plants have capacity values that are between 45% and 95% of maximum capacity, depending on their location and configuration. The article also examines the sensitivity of the capacity value of CSP to a number of factors and shows that capacity-factor-based methods can provide reasonable approximations of reliability-based estimates.
