• CSP with dispatchable thermal energy storage provides multiple benefits to regional grid systems.
• NREL has attempted to quantify this value within U.S. markets (U.S. Western Interconnect).
• Values include:
o Operational (fuel, carbon, system O&M)
o Capacity
o System inertia
o System flexibility

Marginal curtailment of solar assuming equal energy mix of PV and CSP and additional CSP grid flexibility
Low curtailment at 30% solar penetration

At 100ms after PV trip pref for all CSP units is increased by 5%
