7. Flexible, Dispatchable Renewables:
Solar Thermal with Storage
Dispatchable Against Wholesale Energy Market Prices
Provides Regulation, Spinning Reserves &
Power Qualities of Synchronous Generators:
Reactive power support
Dynamic voltage support
Voltage control
Inertia response
Primary frequency control
Frequency and voltage ride-through
Sustained Capacity / Resource Adequacy Value
As grid capacity needs change, stored thermal energy can follow
Reduces overall system integration costs &
emissions, displacing cycling / low-utilization conventional
units
