Thermal Storage. CSP Trough Physical, Commercial

Dear Paul,

I am working with 2013.1.15 version. I wanted to ask you about "Thermal Storage".
In "TES Thermal Capacity", it indicates MWt. Is it MWh? Is it correct?

I was consulting the help and in the first equation of "Storage volume", it uses "t full load". Is would not be an energy?
What temperatures use in the equation?


Thank you very much.

With best regards

Dear Pierre,

Yes, those are MWh of thermal energy.

The thermal energy storage (TES) system capacity in hours is the number of hours that the TES can drive the power cycle at its rated capacity. For a power cycle with a "design gross output" capacity of 111 MWe and a rated cycle conversion efficiency of 0.3774, 6 hours of TES capacity would be:

111 MWe / 0.3774 * 6 h = 1,764 MWht

The 'e' and 't' in the capacity (MW) and energy (MWh) units indicate electricity and thermal energy, respectively.

Because this equation uses the power cycle's rated capacity, you can assume that the temperature would be at the cycle's design inlet temperature.

Best regards,
Paul.
