Pakistan has been facing an electricity shortage since the year 2005, which is negatively affecting the country's agricultural, industrial, and services sectors growth. In this study, Low Emissions Analysis Platform (LEAP®) software was used for forecasting energy mix of Pakistan for the period of 2022–2050 under the baseline and transformation scenarios. Baseline scenario emphasizes to enhance the share of hydro while transformation scenario emphasizes to enhance the share of biomass in total energy mix of Pakistan. Transformation scenario is recommended because hydro plants will retire in future and delay in construction of new hydro plants is noticed due to limited budget. In this regard, electrical energy is harvested using biomass based distributed power generation (BBDPG) for the sustainable economic development of Pakistan. The aggregate capacity of biomass is used which includes agriculture residue, forest residue, municipal waste, and animal waste. The results of this study show that the share of hydro at around 54.09% (614.14 TWh) is dominated over other renewable sources in the baseline scenario, whereas, in transformation scenario the share of biomass at around 33.3% (378 TWh) is dominated over other renewable sources till 2050. Pakistan could generate a total of 1135.20 TWh energy units in 2050, which would be enough to meet the future energy demand of 966.05 TWh by 2050. • Modeling of Pakistan's energy systems for the period 2022 to 2050. • Create balance between power demand and supply for economic development. • Role of biomass in energy mix is significant. • Provide sufficient power at competitive price and avoid capacity shortfall. • Proposed an energy policy for achieving renewable energy supply.

Due to the recent climate change, organizations all over the globe are developing plans for reducing carbon emissions by developing clean energy technologies and energy efficient devices. In this regard, the developments have not been done over the past two decades on green energy in Pakistan and in general, the representation of renewable sources especially biomass feedstock supply such as agriculture residue, forest residue, municipal waste and animal waste for green energy transition pathways is limited. Using the Low Emissions Analysis Platform (LEAP®) software, path for green energy transition is analyzed in Pakistan by incorporating the biomass feedstock under the ongoing and sustainable energy scenarios from 2022 to 2050. Results showed that the bioelectricity production will increase from 18.73 TWh (in the ongoing scenario) to the 265.20 TWh (in the biomass based sustainable energy scenario) till 2050. Furthermore, the development of biomass plants would help in reducing the CO 2 emissions from 138.47 million metric tonnes in the current scenario to 8.71 million metric tonnes in the sustainable energy scenario by 2050. This study will provide the fundamental data and aid the policy makers and other stakeholders to shift toward developing renewable and sustainable energy systems in Pakistan. • Role of biomass in energy mix is significant for Pakistan. • Pakistan is producing 560.19 million tons of biomass resource annually. • Bioelectricity production will increase from 18.73 to 265.20 TWh using biomass till 2050. • LEAP® model is developed for sustainable climate change. • Bioelectricity will reduce CO 2 emissions from 138.47 to 8.71 million metric tonnes.
