Inverter technology being introduced to Australasia by industrial drives manufacturer Bonfiglioli Transmission have been selected for use at the world’s biggest photovoltaic energy installation. Bonfiglioli Riduttori have supplied a total of 475 inverters for the installation in Puertoallano, Spain, which covers an area the size of 185 football pitches, or 118 hectares.
The inverters will be used to transform the DC power produced by 350,000 photovoltaic panels into alternating current. Under suitable climatic conditions, the plant generates 46MW of energy for the Spanish State electrical power company Endesa.
According to Malcolm Lewis, Managing Director, Bonfiglioli Transmission, Australasia, the contract is part of a major drive by Bonfiglioli technology into renewable power applications, including photovoltaic, wind, biomass and thermal power technologies suited to Australasia.
Bonfiglioli Transmission’s earnings from renewable energy applications currently account for about a sixth of their turnover, or about 100 million Euros a year (nearly $A200 million). They are already developing strong interest in renwable power applications in Australasia, including helical/planetary combination drives for wind power applications.
Bonfiglioli internationally will also supply inverters for a second installation in the central Iberian Peninsula, this one a 69MW thermodynamic solar energy plant adjacent to the first installation.
The construction of new green energy installations has also been announced in Italy. These latest plants will be built by the Spanish Renovalia group with Bonfiglioli again supplying the inverters. A total of seven sites will be built to generate electricity using photovoltaic technology. Work on the first, in Bianco, Calabria, is due to begin in about 2 months. The locations chosen for the new plants are in Gravina (18.52MW), Irsilia (30MW), Sicily (8.60MW), Rome (40.48MW), Bianco (15.86MW), Tarquinia (10.57MW) and Nardo (18.57MW).
