7.30.09 | Milan, Italy | From Reuters: The Milan Trade Fair said on Tuesday [July 7] it is commissioning the world's biggest rooftop photovoltaic power installation covering some 270,000 square meters.

"We have had seven offers from general contractors to build the plant and we'll very soon trim that down to five. The winning bid will be the one that offers us the highest rental," said Ferruccio Ferranti, CEO of Sviluppo Sistema Fiera, a unit of the Milan fair group.

Under the deal, the winning bidder will build the plant at a cost that Ferranti estimates at around 70-80 million euros. It will pay the Milan fair a rental fee in return for which it will be able to market the power generated.
