Archimede
This page provides information on Archimede, a concentrating solar power (CSP) project, with data organized by background, participants, and power plant configuration.
Archimede is a parabolic trough plant operating in Sicily, Italy. The plant produces steam (4.72-MW equivalent) sent to a combined-cycle steam turbine rated at 130 MW. This parabolic trough system is the first using molten salt as the heat-transfer fluid. A 2-tank direct system will provide 8 hours of thermal storage.
