Gemasolar is a concentrated solar power plant with a molten salt heat storage system.

It is located within the city limits of Fuentes de Andalucía in the province of Seville, Spain.

[3] The project, which has received a subsidy of five million euros from the European Commission and a loan of 80 million euros from the European Investment Bank, makes use of the Solar Two technology tested in Barstow, California, but is approximately three times the size.

Gemasolar is the first commercial solar plant with central tower receiver and molten salt heat storage technology.

In addition, its storage system allows it to produce electricity for 15 hours without sunlight (at night or on cloudy days).
