How Thermal Energy Storage Enhances the Economic Viability of Concentrating Solar Power

This paper examines the economic performance and rationale of concentrating solar power (CSP) with and without thermal energy storage (TES). We demonstrate that TES can increase the energy and capacity value of CSP and also show that adding TES to a CSP plant can increase its economic viability by increasing its operating revenues to the point that the capital cost of CSP can be justified.
