This Master’s thesis project is the result of the work done thanks to Baker Hughes company - Nuovo Pignone Srl in one of its major manufacturing Italian sites, in Florence. The work was developed in the global supply chain area and more precisely in the energy management one, which also gave me the opportunity to interface with other different business areas within the company. The focus has been on energy in terms of electricity, natural gas and thermal energy, but also on water consumption with the joint goal of reducing both costs and the carbon footprint, which is strongly linked to climate changes, currently one of the priority topics on which global action is required.
