This thesis is the result of the internship carried out at the headquarters of the Same Deutz-Fahr Group, located in Treviglio (BG), which is leader in the construction of tractors and agricultural machinery. The aim of this work is to evaluate the feasibility and economic convenience resulting from the installation of a photovoltaic plant and a CCHP system serving the plant area. The objectives of these investments are the achievement of primary energy savings and CO2 emissions reduction. First of all, a brief description of the Group, its history, the structure of Treviglio headquarters and the activities carried out has been made. Subsequently, methane and electricity distribution grid of the plant have been reported, boilers and chillers installed have been described and, in addition, an overview of the heating and air conditioning systems serving the various buildings has been done. After having provided a general overview of the plant, a detailed analysis has been carried out with the purpose of obtaining the annual load curves on hourly basis of the thermal, electrical and refrigeration demand, relating to the industrial area. Then a description of the technologies considered during this study has been presented, together with the analysis of the economic data necessary for the evaluation of the investments. Finally, the Excel model on hourly basis has been outlined. Through this model it has been possible to determine the optimal size of the energy production plants and to evaluate the economic and environmental benefits resulting from their installation. Different configurations have been presented based on the needs of the company.
Il presente lavoro di tesi è frutto dell’attività di tirocinio svolta presso la sede di Treviglio (BG) del Gruppo Same Deutz-Fahr, leader nella costruzione di trattori e macchine agricole, e ha come scopo valutare la fattibilità e la convenienza economica dell'installazione di un impianto fotovoltaico e un sistema trigenerativo a servizio dell'area dello stabilimento. L’obiettivo di questi investimenti è quello di conseguire un risparmio di energia primaria e una riduzione di emissioni di CO2. Per prima cosa è stata fatta una breve descrizione del Gruppo e della sua storia, della struttura della sede di Treviglio e delle attività portate avanti al suo interno. Successivamente sono state riportate le reti di distribuzione del metano e dell’elettricità presenti nello stabilimento e sono state descritte le centrali termiche e i chiller installati al momento. Inoltre, è stata presentata una panoramica degli impianti di riscaldamento e condizionamento a servizio dei vari immobili. In seguito, si è passati all’analisi dettagliata che ha portato alla costruzione delle curve di carico annuali su base oraria della richiesta termica, elettrica e frigorifera, relative all’area industriale. A questo punto, sono state riportate prima una descrizione delle tecnologie prese in esame e in seguito un’analisi dei dati economici necessari per la valutazione degli investimenti. Infine, si è passati alla descrizione del modello orario in Excel attraverso cui è stato possibile determinare la taglia degli impianti di produzione di energia e la valutazione dei benefici economici ed ambientali conseguenti alla loro installazione. Sono state presentate diverse configurazioni in base alle necessità dell’azienda.

Abstract
This thesis is the result of the internship carried out at the headquarters of the Same Deutz-Fahr Group, located in Treviglio (BG), which is leader in the construction of tractors and agricultural machinery. The aim of this work is to evaluate the feasibility and economic convenience resulting from the installation of a photovoltaic plant and a CCHP system serving the plant area. The objectives of these investments are the achievement of primary energy savings and CO2 emissions reduction. First of all, a brief description of the Group, its history, the structure of Treviglio headquarters and the activities carried out has been made. Subsequently, methane and electricity distribution grid of the plant have been reported, boilers and chillers installed have been described and, in addition, an overview of the heating and air conditioning systems serving the various buildings has been done.
