Planta Solar 20

This page provides information on Planta Solar 20, a concentrating solar power (CSP) project, with data organized by background, participants, and power plant configuration. Abengoa Solar's Planta Solar 20 (PS20) is a 20-megawatt power tower plant being constructed next to the PS10 tower, and it will be the largest power tower in the world. The PS20 receiver has been significantly improved with respect to its predecessor PS10 receiver. For example, designing a natural circulation receiver and increasing incident solar radiation capture will increase net electrical power output by 10 percent. The 160-meter tower was designed to reduce the visual impact of its height. The plant has the capacity to generate more than 40 gigawatt-hours of energy each year, enough to supply power to 10,000 homes.

Status Date: March 20, 2017
