Plant Solar 20 (PS20)

The Solar Collectors

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.

Molten Salt Energy Storage

-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.

The Principle

-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

Steam Turbine Generator

The turbine generator is designed around a wet-cooled Rankin cycle for optimum efficiency

Owner: Abengo Solar (Designed/constructed Abener-Abengoa)

The Tower

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.

Overview:

-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

Location: Sanlucar, Andualusia, Spain
