A case study of green design in electrical engineering: an integrated LCA/LCC analysis of an Italian manufactured HV/MV power transformer

The aim of this study is to present an experience of the application of the Sustainability Assessment Methodology to a traditional private business. It deals about a significant case study in which CESI S.p.A. applied an integrated LCA/LCC analysis to a 250 MVA HV/MV power transformer produced from the Italian Tamini Trasformatori S.r.l. and remanufactured from the traditional design- according to an innovative environmentally sustainable vision – changing the insulation material from mineral to ester oil. The study was the starting point to realize an Environmental Product Declaration and the preceding Product Category Rules, currently underway. Such an innovative and green product development tries to anticipate market demands, to improve the environmental performance and benefits of the energy transformation process, to increase the migration to bio and renewable sources solutions.
