Cellino San Marco - Italy43 MWp Photovoltaic Power Plant

AES Solar was established in 2008 as a joint venture between the AES Corporation and Riverstone Holding LLC. It is a global company that develops, finances, constructs and manages utility-scale solar photovoltaic power plants across the world. The company seeks to be a leading developer, owner and operator of utility-scale solar power plants that will be connected to the power grid, in order to supply homes and businesses with clean, renewable energy.

Its Italian subsidiary AES Sole has started the construction of a large-scale park in Pouilles in Italy. With an output of 38,5 MW, the park consists of 3 sites, 573,100 solar panels spread over 100 hectares of land. This park will have a power generation capacity equivalent to the consumption of 18,000 homes, i.e. 50,000 inhabitants (based on 3,300 kWh per year). A park of this type represents an annual saving of 28,000 tonnes of CO2.

In order to gain a quick return on its investment, AES Sole wanted to optimise the construction time (9 months), and has called upon a reliable and competitive player that can offer attractive technical solutions and a suitable operating and maintenance contract.
