Archimede combined cycle power plant (also known as Centrale a ciclo combinato Archimede, once Centrale Enel Priolo Gargallo[1]) is an integrated solar combined cycle (ISCC) power generation plant at Priolo Gargallo near Syracuse in Sicily, Italy.

This means that every unit of thermal energy coming from the solar field delivers electricity only in accordance with the coefficient of efficiency of the steam section, not being involved in the gas turbines.

The fluid is then drawn from the hot reservoir to produce steam at high pressure and temperature, which is sent to Enel's nearby combined-cycle plant, where it contributes to electricity generation.

This system enables the solar field to generate steam at any time of the day and in all weather conditions until the stored thermal energy is depleted.

The solar field is relatively small, being less than half of the area dedicated solely to the conventional power plant section.
