| Abstract | The present tariff structure in Pakistan does not adequately reflects the cost of electricity supply. There is no differentiation between peak and off-peak consumption. There are no incentives for those consumers who avoid consuming electricity during peak hours. All this put stress on the system's generating capacity. The Government has recently formulated a policy to promote power generation from the private sector and is giving many incentives to the private power producers. Tariff design is a very important element in the power sector's reforms. In this study, the costs of electricity supply are calculated for Pakistan's power system. A generation expansion optimization model (WASP-III) is used to get the optimum expansion plan for the period 1996-2018. Marginal capacity cost is calculated using average incremental approach. In order to calculate the value of Marginal energy cost, ICARUS software is used. WASP-III is not suitable for estimating marginal energy costs since an hour by hour simulation is required for tariff design. The day is divided into two periods, peak and off-peak. Two seasons for all regions in the country have been considered in this thesis. Costs of transmission and distribution network expansion are taken directly from references. The costs of electricity supply are calculated for different voltage levels, time of use (peak and off-peak) and seasons. The policy framework and package of incentives for private sector power generation projects in Pakistan is also discussed in this study. All the pros and corns are described and some recommendations are made in the end to improve the present status of Pakistan's power sector. Tariff setting is a continuous process and the tariff structure chalked out in this study should be thought of as reflecting one step in a transitional process towards tariff setting. However, this new tariff structure and recommendations about the new power policies would be helpful for Pakistan's challenge to enter the twenty first century as a self-reliant nation, with a vibrant and resilient economy. |
