Impact Analysis of Marsyangdi Corridor 220kV Transmission Line on the Operation of Integrated Nepal Power System

Abstract
Despite having an enormous hydropower potential and being one of the early adopters of hydropower as a source of energy, Nepal has not been able to make significant strides in this sector. Since most of the hydropower generating station are located in central hilly regions and majority of load centre are location in Terai region of Nepal, the transportation of power remains a huge challenge in Nepal. Additionally, there is significant power loss in the power system itself. Currently, Nepal is focusing on developing high voltage transmission line to evacuate the power as well as decrease the existing loss in the system. Marsyangdi Corridor 220kV Transmission Line Project (MCTLP) is a project that aims to develop 113 km of double circuit line from Dharapani in Manang to Aaptari in Chitwan to evacuate the power produces in Marsyangdi river basin and its tributaries. The construction of this high voltage line is expected to significantly ease the burden on current Middle Marsyangdi-Markichowk and Damauli-Bharatpur transmission line along with decreasing the overall loss in the system.
Description
The research concludes that the construction of MCTLP transmission line can decrease the loss on transmission system by 45.34 MW. Furthermore, the voltage profile and line loading of the transmission line was also improved. The payback period for the project is found to be 11.48 years.
