The work has begun in the town of Calasparra, Murcia, for the construction of a thermal solar power plant of a large scale. It’s called Puerto Errado 2, and it will have the capacity of 30 MW using Linear Fresnel technology, patented and developed by Novatec Biosol AG.
Puerto Errado 2 is 300,000 m2 of flat mirrors that will capture the solar energy necessary to operate two 15 MW turbines that produce electricity. The facility includes the largest direct steam generator used in the solar field.
The solar field with Novatec Linear Fresnel consists of a direct steam generator comprising groups of flat mirror rows (primary reflectors). Each group reflects and focuses solar radiation onto a focal line. This line is an receiver that comprises a secondary reflector and an absorber tube. The water that flows through the absorber tube is converted into steam and is collected in a drum to be shipped to a turbine / steam generator.
Novatec has stressed that Linear Fresnel solar technology “uses less material than current solar thermal technologies, the manufacture of solar field components is highly automated and its installation is simple. In addition, the plant takes up much less land and uses less water than existing plants allowing energy generation to be more profitable and with less environmental impact.”
The Swiss energy companies Elektra Baselland (EBL) and Industrielle Werke Basel (IWB) are the investors of the Novatec project. Puerto Errado 2 has been approved after evaluating the results of the demonstration plant of 1.4 MW, Puerto Errado 1, which began supplying power to the grid in March 2009.
