Each heliostat, with a surface area of 1,291 SF, reflects the solar radiation it receives onto the receiver, locateD on the top of a 541 foot high tower, proDucing high-temperature, high pressure steam that is directly converteD into electricity by a Rankin turbine/generator. PS20 is part of the larger 300 MW Solucar Complex pro- ject (collaboration of Ciemat, the IDEA, anD the University of Seville) which includes a range of solar technologies such as low anD high concen- tration photovoltaic, tower thermoelectric, para- bolic-trough collector anD Stirling Dish plants. Location: Sanlucar, AnDualusia, Spain Date Commissioned: 2009 (construction phase: 3 years) For clouD transients, the plant has a 20-MWh Rated Capacity: 20 MW Annual Production:48 GWh per year thermal capacity saturateD water thermal storage Capacity: 27%. (solar resource: 2,012 kWh/m2/year) system rateD for (1) hour of operation. Carbon Offset: 12,000 tons per year Project Owner: Abengo Solar (Design/costructionAbener-Abengoa) Generation Offstaker: EnDesa Distribution. 25-year PPA at $0.3722/kWh Generation Technology: Power Tower Water/ Direct Steam CSP, (1,255) dual-axis heliostat reflectors, (1) wet-cooleD Rankine cycle steam turbine Cost: $109.8 million CleanEnergy | ACTION PROJECT http://www.cleanenergyactionproject.com/ .
