Europe’s first commercial concentrating solar power tower plant was opened near the sunny Andalusian city of Seville. The 11 MW plant, known as the PS10 solar power tower, produces electricity with 624 large heliostats. Each of these mirrors has a surface measuring 120 square meters (1,290 square feet) that concentrates the Sun’s rays to the top of a 115 meter (377 feet) high tower where a solar receiver and a steam turbine are located. The turbine drives a generator, producing electricity.

The Basic Process:

Reflected mirrors (Heliostats) track the motion of the sun throughout the day.

And redirect the sun’s ray to a focal point atop a central receiver tower.

Which has panels specifically designed to optimize heat and radiation absorption.

“Cold” molten salt stored in a tank at 290 degrees Celsius is pumped up the tower to the receiver.

Here it is heated to 565 degrees Celsius by the absorbed solar energy.

The salt is kept molten through heat tracing on the pipes; electrical resistance to maintain the temperature during transfer.

The heated salt is contained in a “hot” storage tank and used when power is needed from the plant.

It is then transferred to a steam generator system, where it produces superheated steam through a conventional Rankine cycle.

The salt is returned to the cold tank where it is stored and eventually reheated in the receiver.

The produced steam is used to turn turbines, which subsequently power electrical generators.

The resulting electricity is sent through a step-up transformer and sent down power lines.

The salt storage system allows for continuous power production through cloudy periods and well after sunset to meet peak demands.
