Power Sector pathways for Pakistan is developed in this paper to depict the future challenges & aspects associated with its forecasting and planning on basis of modeling tools. Major pathways will be taken for further study in predicting focus on energy source for power generation. Three scenarios (BAU, NC & GF) will be discussed over a 20 years period (2011 to 2030) and the results from these scenarios will highlight our focus on fossil fuels or either renewable for future endeavors. The result will provide the forecasting of power sector up to 2030 on basis of electric consumers growth, level of activities, final energy intensity, forecasted growth & other factors. Therefore, the overall result will indicate efficient factors for future evaluation of policies on energy planning. The result also provides the vision for other developing countries in the region to make strategy for renewable energy expansion on massive scale
