(orcid)0000-0003-0231-8795 Opportunities and economic assessment for a third-party delivering electricity, heat and cold to residential buildings 2023 Access copy available to the general public Unrestricted In the present context of energy transition towards a carbon neutral society, residential sector plays an important role to combat climate change since it represents about 40% of the global final energy consumption and 30% of direct CO2eq emissions in the European Union. Polygeneration systems, facilitating the integration of renewable energies, are a feasible alternative enabling efficient use of natural resources with low environmental impact. This work analyzes the economic viability, in terms of net present value (NPV), and environmental benefit (CO2eq emissions) of an energy supplier company playing the role of an aggregator for both demand and supply. As an owner of a polygeneration system, optimally designed through a MILP approach, it delivers various energy services (electricity, space heating, domestic hot water and cold) to several customers (50 dwellings). The analysis is performed, considering three different business models, in two different locations, Zaragoza (Spain) and Marseille (France), with different energy demands, energy mixes and energy regulations. The optimal configuration obtained, consisting of cogeneration module, PV, reversible heat pump, boiler and thermal energy storage has shown to be very resilient and cost-effective in the scenarios analyzed. Results indicate that the proposed scheme represents an added value for both the supplier company (aggregator), with a positive, and the final customers (owing savings greater than 30%), with significant reduction of CO2eq emissions. info:eu-repo/grantAgreement/ES/DGA/T55-20R info:eu-repo/grantAgreement/ES/DGA-FSE/Building Europe from Aragon info:eu-repo/grantAgreement/ES/MINECO/ENE2017-87711-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 9.0 2023 THERMODYNAMICS 3 / 78 = 0.038 2023 Q1 T1 ENERGY & FUELS 24 / 171 = 0.14 2023 Q1 T1 2.11 2023 Electrical and Electronic Engineering 2023 Q1 Energy (miscellaneous) 2023 Q1 Energy Engineering and Power Technology 2023 Q1 Building and Construction 2023 Q1 Civil and Structural Engineering 2023 Q1 Renewable Energy, Sustainability and the Environment 2023 Q1 Industrial and Manufacturing Engineering 2023 Q1 Management, Monitoring, Policy and Law 2023 Q1 Mechanical Engineering 2023 Q1 Modeling and Simulation 2023 Q1 Pollution 2023 Q1 Fuel Technology 2023 Q1 15.3 2023 info:eu-repo/semantics/article info:eu-repo/semantics/submittedVersion Gronier, Timothé Franquet, Erwin Serra, Luis M.
