Operational experience of the polygeneration plant in Parc de l´Alba (Spain): Start-up and first results

Polygeneration systems are highly integrated systems characterized by the simultaneous production of different services (electricity, heating, cooling) by means of several technologies to obtain a higher efficiency than that of an equivalent conventional system. This paper presents some preliminary monitoring results of a polygeneration plant installed in a technological park in Cerdanyola del Vallès (Spain) in the framework of the Polycity project of the European Concerto Program. The plant is composed of three cogeneration gas engines, a direct fired exhaust gas absorption chiller, a single-effect absorption chiller, a compression chiller, a natural gas boiler and a chilled water storage tank of 4000 m³.
