The data provided in this paper can be used as input data to develop an energy system model for Argentina. As an illustration, these data were used to develop an energy system model using the cost-optimization tool OSeMOSYS for the period 2015–2050. For reference, that model is described in Appendix A and its datafiles are available as Supplementary Materials. Appendix figure A3 for Argentina is repeated below. This is purely illustrative. It shows a zero-order model of the production of electricity by technology over the period 2020 to 2050 for a least cost energy future. Using the data described in this article, the analyst can reproduce this, as well as many other scenarios, such as net-zero by 2050, in a variety of energy planning toolkits.
The data provided were collected from publicly available sources, including the reports of international organizations, journal articles and existing model databases. The dataset includes the techno-economic parameters of supply-side technologies, installed capacities, emissions factors and final electricity demands. Below shows the different items and their description, in order of appearance, presented in this article.

1.2 Techno-economic Data for Electricity Generation Technologies
The techno-economic parameters of electricity generation technologies are presented in Table 2, including costs, operational lives, efficiencies and average capacity factors. Cost (capital and fixed), operational life and efficiency data are based on the data used in the South America Model Base [7] and are applicable to South America. Projected cost reductions for renewable energy technologies were estimated by applying the cost reduction trends from a 2021 IRENA report focussing on Africa [8] to these South America-specific current cost estimates. These projections are presented in Table 3. Where technologies were not included in SAMBA, namely diesel generation technologies, medium hydropower plants and decentralised solar PV with storage, costs were estimated based on values from other reports by the IRENA [8,9]. The cost and performance of parameters of fossil electricity generation technologies are assumed constant over the modelling period. Country-specific capacity factors for solar PV, wind and hydropower technologies in Argentina were sourced from Renewables Ninja and the PLEXOS-World 2015 Model Dataset [3,10,11], as well as an NREL dataset [12]. Capacity factors for other technologies were sourced from SAMBA [7] and are applicable to South America. Average capacity factors were calculated for each technology and presented in the table below, with daytime (6am − 6pm) averages presented for solar PV technologies. For more information on the capacity factor data, refer to Sect. 2.1.

1.3 Techno-economic Data for Power Transmission and Distribution
The efficiency of power transmission and distribution were taken from the SAMBA dataset [7], which gives estimated efficiencies by country, including projected efficiencies to 2063. The efficiencies of transmission and distribution in Argentina are therefore assumed to reach 94.0% and 95.0% in 2030 and 94.0% and 96.0% in 2050 respectively. The costs and operational life of transmission and distribution technologies were also taken from SAMBA, which gives estimates relevant to South America, including future projections.

1.4 Techno-economic Data for Refineries
Argentina has an estimated 651kb/d domestic refinery capacity [13]. In the OSeMOSYS model, two oil refinery technologies were made available for investment in the future, each with different output activity ratios for Heavy Fuel Oil (HFO) and Light Fuel Oil (LFO). The technoeconomic data for these technologies are shown in Table 5.

Assumed costs are provided for both imported and domestically-extracted fuels. The fuel price projections until 2050 are presented below. These are estimates based on an international oil price forecast [15] for oil and oil products, the SAMBA dataset [7] for natural gas, and a report on international biomass markets [16].

1.6 Emission Factors
Fossil fuel technologies emit several greenhouse gases, including carbon dioxide, methane and nitrous oxides throughout their operational lifetime. In this analysis, only carbon dioxide emissions are considered. These are accounted for using carbon dioxide emission factors assigned to each fuel, rather than each power generation technology. The assumed emission factors are presented in Table 7.

1.8 Electricity Demand Projection
An electricity demand projection was calculated based on the Current Policy Scenario regional demand projections of the OLADE Energy Outlook 2019 [22], which were divided by country based on historic consumption data from the International Energy Agency (IEA) [23]. Final electricity demand in Argentina was estimated at 472.67PJ in 2016 and is forecasted to reach 719.46PJ by 2030 and 1190.14PJ by 2050. For more information on the final electricity demand projection, see Sect. 2. Figure 4 below shows the final electricity demand projection.
