EL REBOSO II 50-MW Solar Thermal Power Plant

This page provides information on EL REBOSO II, a concentrating solar power (CSP) project, with data organized by background, participants, and power plant configuration. EL REBOSO II is one of the first parabolic trough power plants in Europe without storage. Located in southern Spain, La Puebla del Río (Sevilla), this power plant began construction in 2009 and will begin operating in 2011. Both EL REBOSO II and EL REBOSO III will help the Spanish power grid meet peak summer demand primarily caused by the high energy consumption of air conditioning units.
