An Abengoa (XETRA:AYO.DE) press release reveals the dedication of an 11 MW Solar Tower, the PS10, the world's first commercial solar tower power plant. Solucar, an Abengoa company, constructed the plant in the municipality of Sanlucar la Mayor (Seville),which will be operated by Abengoa.
The 11 megawatt PS10 solar power plant will generate 24.3 GW/hr per year of clean energy and comprises 624 movable heliostats (mirrors). Each of the mirrors has a surface area of 120 square meters (1292 square feet) which concentrates the Sun's rays to the top of a 115-meter (377 foot) high tower where the solar receiver and a steam turbine are located. The turbine drives a generator, producing electricity. The two axis heliostats move automatically as a function of the solar calendar. This power plant alone will prevent the emission of 18,000 tons of CO2 per year.
The investment required to build the concentrating solar power plant amounted to €35 million (US$47 million), with a contribution of €5 million (US$6.7 million) from the EU's Fifth Framework Program for research, awarded for the project's innovative approach.
The 300 MW Sanlucar la Mayor Solar Platform will be completed by the year 2013 and, utilizing a wide range of solar technologies will produce sufficient energy to cover the consumption of some 180,000 homes, equivalent to the needs of the city of Seville. The project requires a 1.2 billion euro (US$1.6 billion) investment.
The remaining Sanlucar la Mayor Solar Platform power plants will be stagger-constructed over the next six years to convert the Platform into a diverse technology macro-project that will include solar tower, parabolic-trough collector, Stirling dish, and low and high concentration photovoltaic plants.
The PS20, a solar tower 20 megawatt plant, similar to the PS10 plant and a parabolic-trough collector demonstration plant are currently under construction
