Project Background

An overestimation of long-term electricity demand will result in significant wasteful investment in excess power plants, whilst an underestimate will result in the insufficient generation and inadequate demand. According to the NEA annual report, the transmission line length in Nepal has increased from 279.50 km in Fiscal Year (FY) 2076/77 to 604.74 km in 2077/78. From this, it can be observed that the transmission system in Nepal is developing at an accelerated rate. For such a fast-developing system, classical forecasting methods give a poor performance, hence for such systems a computational method based on the knowledge-based expert system that takes into account the present situation of the power system, all electrical variables, and non-electrical variables are found to be more accurate. At the same time, scenario-based strategies for the optimum and reliable operation of the future power grid, backed by strong technical, financial and feasibility analysis is necessary to make the grid future-ready.

The optimum performance of the proposed transmission lines in transmission system development plan of Nepal in the subsequent years will only be obtained if the existing and the soon-to-be-completed transmission lines are maintained, reinforced, and modernized on a timely basis considering the change in the generation and the load scenario in the subsequent years. This might include reconfiguration of the network to reduce system overloads, augmenting the capacity of the existing substation to accommodate the incoming power and adding state-of-the-art automation systems and software.
