Diving towards a Complete Decarbonisation of the Spanish Energy System from a Top-down Viewpoint and Data Analysis

Several countries have recently published their respective national plans of energy and climate to having an economy partially decarbonized in 2030, leading the worldwide task of climate change mitigation towards a net zero-carbon economy by 2050. In the Spanish report, the objective scenario expects to achieve a renewable share in the power system as much as 74%. This research aims to contribute in the discussion by providing a detailed method based on data analysis helped by an energy model. Data collection has allowed an excellent representation of the Spanish energy system structure for the reference year of calibration, 2017. Inputs of the EnergyPLAN model have been properly connected with national final energy balance (FEBs) to expand the analysis further, getting hourly results and a transparent set of policies for the two reference years. The role of hydrogen and power-to-heat technologies managing variable renewable energies, as well as complete decommission of nuclear and fossil fuels units have been included and discussed. Furthermore, top-down viewpoint of the method aims to define a feasible framework to work in future connections with Integrated Assessment Models (IAMs). Results evince positive conclusions regarding renewables. Commitment of 74% is fulfilled facing 2030, and Spanish economy could run with a 100% renewable energy system by 2050. Respect to 2017, fifteen and five times more installed capacity of solar-PV and wind onshore by 2050, respectively, would be required to achieve the desired target. Discussion addresses the biomass potential of this region. Limitations of the method and further work are esteemed throughout discussion and conclusions.
