A heliostat- is a plane mirror that turns with the rotation of the Sun to keep a constant focal point
The mirrors
-Each of the heliostats consists of multiple smaller mirrors with two degrees of freedom to maximize the radiations energy concentration on the tower
-The total surface area of each heliostat is 1,291 sq. ft
PS20 consists of a solar field containing 1,255 mirrored heliostats designed by Abengoa Solar.
-The salt consists of 40% potassium nitrate, 60% sodium nitrate
-This allows heat to be stored for later use when the solar energy is not available.
-A circular array of heliostats (2 axis tracking mirrors) are used to concentrate sunlight to a central receiver mounted on the top of a tower
-Higher temperatures = higher yields and higher overall efficiency
-Energy can be stored in the form of Steam or molten salts
The turbine generator is designed around a wet-cooled Rankin cycle for optimum efficiency
Owner: Abengo Solar (Designed/constructed Abener-Abengoa)
A heat transfer medium in this receiver absorbs the highly concentrated radiation, and converts it into thermal energy to be used by a turbine.
The Tower uses the heat to produce 500degC steam which is converted to electricity via a turbine generator.
-Rated Capacity: 20 MW
-Annual Production: 48 GWh per year
-Capacity: 27%. (solar resource: 2,012 kWh/m2/year)
-Carbon Offset: 12,000 tons per year
-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
