The Lower Manang Marsyangdi Hydroelectric Project (LMMHEP) is located in the high Himalayan area of Gandaki zone of Gandaki Pradesh in western Nepal. The Project area lies in Annapurna Conservation Area (ACAP).
LMMHPP will utilize the discharges from intermediate catchment as well as the tailrace of MMHEP by the help of a collection pond. The catchments area at headwork of the project is 1,693 km2 and the elevation of catchment is ranging from about 2100 masl to 7800 masl. The powerhouse of the project will be at an elevation range of 1,728–1,740 masl. BPC obtained survey license of Lower Manang Marsyangdi Hydroelectric Project from Department of Electricity Development (DoED) in 2009 and carried out feasibility study & EIA. EIA of the project has been approved by GoN in 2070.
The connection agreement was signed in 2018 with NEA for 104 MW following the PPA guidelines of NEA.
Generation License (140 MW RoR type) has been received on Kartik 18, 2075. However, so as to fit to Marsyangdi Cascade projects, this project has been re-designed to take tail water of PROR Manang Marsyangdi project so that this project is also a PROR project. The project now has been re-optimized at 139.2 MW to meet the requirement of NEA’s guideline for concluding the PPA. Accordingly, the Supplementary EIA (SEIA) has been conducted and submitted for the approval process.
Besisahar - Chame Feeder Road is a motorable road connecting the powerhouse and the headworks areas.
