Gemasolar

SolarSpain

19.9 MW solar tower near Seville, the first commercial plant to run on molten salt storage around the clock.

Overview

Opened in 2011, Gemasolar focuses some 2,650 mirrors on a central tower that heats molten salt. Its 15 hour storage tank let it deliver power for 24 hours straight in summer. The design became a model for larger tower plants in Chile, Morocco and Dubai.
