Portugal is joining the group of countries where it is feasible to install PV systems without a subsidy programme. Donauer Solartechnik from South Germany reports an example of a plant that will be used to generate power for own consumption in the southern European market: The system provider has installed a 65-kW solar power plant on a meat-processing factory, together with its Portuguese partner Ceasa. According to the planners, it will cover 25% of the electricity requirements of the factory.

The plant, which belongs to Companhia Nacional de Carnes in Palmela, is not equipped with batteries; all of the power generated is used directly as a kind of internal baseline load. If the power is not completely consumed by lighting, computers and other devices, for example on weekends, then the factory uses the solar power for three cold storage rooms. This means that surpluses do not occur, says José Luis Herrera, Managing Director of the Ceasa Group in Portugal: "This is a solar power system for direct consumption." Ceasa developed the project in collaboration with the Portuguese branch of Donauer. Given the local solar radiation conditions, an annual yield of 95 MWh is expected.

Donauer sees the project as a milestone in the Portuguese market, according to Managing Director Rudolf Donauer: "We are aiming for a leading position in the area of commercial internal power consumption in Portugal." The company places particular emphasis on innovative solutions for the direct use of solar power in Europe.
