Currently, imports from the European Union are used when indigenous production is unable to meet demand. However, growing import dependency in winter represents not only a potential threat to the security of supply but also electricity import with a heavy GHG content. The development of decentralized power generation through natural gas-fired combined heat and power (CHP) plants could be a short-medium run solution allowing to produce electricity on the Swiss territory during winter. In this work, we evaluate how the replacement of a part of the inflows from neighbouring countries by decentralized CHP plants fueled by natural gas impacts the hourly carbon footprint of the electricity consumed in Switzerland. We developed a four-step methodology to answer this question. Firstly, we assess, for the years 2016 to 2019, the GHG content of the electricity consumed in Switzerland in accordance with the consumption principle and applying the attributional Life Cycle Analysis (LCA) approach. Secondly, based on natural gas delivery data, we modelled hourly gas consumption for heating purposes by means of the heating degree-hour method. Then, based on the previous part, we simulated hourly electricity production with natural gas CHP plants. Finally, we assessed the hourly GHG emission from electricity consumption with the new solution. The results show that, actually, imports impact strongly and negatively the GHG footprint of the electricity consumed in Switzerland. The results of the last part show that the development of decentralized power generation through natural gas-fired CHP plants can lower the GHG footprint of the electricity consumed in Switzerland. Indeed, in nearly all the scenarios, the naturalgas CHP solution is a less-GHG-emitting alternative to imports. 000009057 540__ $$acorrect 000009057 592__ $$aHEG-VS 000009057 592__ $$bInstitut Entrepreneuriat & Management 000009057 592__ $$cEconomie et Services 000009057 65017 $$aEconomie/gestion 000009057 6531_ $$9eng$$aelectricity production 000009057 6531_ $$9eng$$aelectricity imports 000009057 6531_ $$9eng$$ahourly GHG emission factor 000009057 6531_ $$9eng$$aCHP 000009057 6531_ $$9eng$$anatural gas 000009057 655_7 $$anon-published full paper 000009057 700__ $$aSimon, Emilie$$uUniversity of Applied Sciences and Arts Western Switzerland (HES-SO Valais-Wallis) ; University of Lausanne, Switzerland 000009057 700__ $$aCimmino, Francesco Maria$$uUniversity of Applied Sciences and Arts Western Switzerland (HES-SO Valais-Wallis) 000009057 700__ $$aGenoud, Stéphane$$uUniversity of Applied Sciences and Arts Western Switzerland (HES-SO Valais-Wallis) 000009057 711__ $$aThe 1st IAEE Online Conference$$cOnline$$d2021-06-07$$m2021-06-09 000009057 773__ $$tProceedings of the 1st IAEE Online Conference 000009057 8564_ $$s864944$$uhttps://arodes.hes-so.ch/record/9057/files/Author%20postprint.pdf$$9536ad553-4e00-403c-a39d-55931eb41132 000009057 906__ $$aNONE 000009057 909CO $$ooai:hesso.tind.io:9057$$pECONOMIESERVICES_ALL$$pGLOBAL_SET$$pECONOMIESERVICES_CONFERENCE$$qDOMAINE_ECONOMIESERVICE_CONFERENCE 000009057 950__ $$aI1 000009057 980__ $$aconference 000009057 981__ $$aconference
