Annual Energy 448.35 GWh

About the Project

The Malumela Seti Nadi Peaking Hydroelectric Project is a 72 MW clean energy project designed to strengthen Nepal's power supply using the Seti River.

As a Peaking Run-of-River (PROR) scheme, it uses 4-hour peaking storage to generate power when electricity demand is highest.

It is expected to generate 448.35 GWh annually through a 132 kV transmission connection, with a four-year construction period and long-term project viability.
