The Cristian Lay group, through Alter Enersun and Alterna Energía, has been awarded a contract worth 349,000 euros for Tersa, the public waste treatment company in the Barcelona area.
The contract consists of the renovation of the roof of the CTRM (Municipal Waste Treatment Centre) of Gavà-Viladecans, in which Alterna Energía will execute a photovoltaic installation with a capacity of 422 kW.
The renewable installation will generate the equivalent of the annual consumption of 220 families, also avoiding the emission of more than 700,000 kg of CO2 into the atmosphere.
