The data provided in this paper can be used as input data to develop an energy system model for Myanmar. 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. Figure 1 shows a zero-order model of the production of electricity by technology over the period 2020 to 2050 for a least cost energy future. This is purely illustrative. 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.
1.1 Existing Electricity Supply System
The total power generation capacity in Myanmar is estimated at 5018.33 MW in 2018 [3,4,5,6]. The estimated existing power generation capacity is detailed in Table 1 below [3,4,5,6]. The methods used to calculate these estimates are described in more detail in Section 2.1.

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 reports by the International Renewable Energy Agency (IRENA) and the ASEAN Centre for Clean Energy (ACE) [7,8] and are applicable to Asia. Projected cost reductions for renewable energy technologies were estimated by applying the cost reduction trends from a 2021 IRENA report focussing on Africa [9] to these Asia-specific current cost estimates. These projections are presented in Table 3. 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 Myanmar 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 IRENA and ACE [7] and are applicable to Asia. 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 Section 2.1.

1.3 Techno-economic Data for Power Transmission and Distribution
The combined losses in electricity transmission and distribution in Myanmar are estimated based on an International Energy Agency (IEA) dataset presented by Index Mundi [13], which gives estimated combined losses in 2014. It was then assumed that combined losses would be reduced to 5% by 2050, falling in a linear fashion. Combined transmission and distribution efficiency in Myanmar is therefore assumed to reach 86.0% and 95.0% in 2030 and 2050 respectively. The combined costs of power tansmission and distribution are estimated based on a report by the Economic Research Institute for ASEAN and East Asia (ERIA) [14], which gives cost estimates for several real-life projects in ASEAN. For more detail, see section 2.In the following table, the techno-economic parameters associated with the transmission and distribution network are presented.

1.4 Techno-economic Data for Refineries
Myanmar has an estimated 57kb/d domestic refinery capacity [15]. 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 Asia-specific cost estimates produced by the Asia Pacific Economic Cooperation (APEC) and ERIA [17.18], with an international average biomass price in 2020 assumed for imported biomass [19].

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
Final electricity demand in Myanmar was estimated at 55.27 PJ in 2016 and is forecasted to reach 95.04 PJ by 2030 and 137.52 PJ by 2050 in a Business as Usual (BAU) scenario. The estimated projection in figure 3 was estimated by applying the electricity demand growth rate of neighboring countries in a BAU scenario from the APEC Energy Supply and Demand Outlook 7th Edition [17] to historic demand data from the IEA [25]. Figure 4 below shows the final electricity demand projection.
