Middle Marsyangdi Hydropower Station

Middle Marsyangdi Hydropower Station with installed capacity of 70 MW and annual design generation of 398 GWh is located at Bhoteodar, Siundibar, Lamjung. It was commissioned in 2008. It has consistently performed well thereby generating 457.318 GWh this year exceeding all previous years generations since its commissioning. Its outstanding operational performance is rightly supported by periodic overhauling of Units.

Emergency maintenance of turbine parts of Unit No.2 and maintenance of service gate at dam site were also carried out during the same period. A 12.5 MVA Power Transformer brought from Dhalkebar was installed at MMHPS transformer bay which allowed the local IPP generation to be connected to 132 KV and also the problem of frequent power outages at Head Works while taking power from Udipur Substation were eliminated after the installation of this transformer.



Automatic operation of Desander is now possible afterthe replacement of calibrated sensor at the desander nos. 3&2 flushing gate. Primary Controller of Unit No. 2 has been restored (Under the existing service contract with ALSTOM ) thereby ensuring safety against redundancy and running hour of Unit No. 1 and Unit No.2 were also adjusted as per actual.
