Middle Myagdi HPP

Project Overview

Middle Myagdi Hydropower Project (MMHP)

The **Middle Myagdi Hydropower Project** is a Run-of-River (RoR) type scheme designed to harness the energy of the **Myagdi Khola**. Located in the Malika Rural Municipality of Myagdi District, Gandaki Province, this project is a key initiative by Pinnacle Urja Invest to contribute to Nepal's renewable energy goals.

With a robust design discharge of 41.54 m³/s and a gross head of 28 meters, the project is optimized for high efficiency. It is strategically planned to utilize the perennial flow of the river while maintaining strict environmental compliance and supporting the local infrastructure of the Dhaulagiri region.

Capacity: 9.55 MW
Annual Energy: 54.15 GWh
Gross Head: 28.0 m
Discharge: 41.54 m³/s

Regional Context

Geography & Accessibility

Lesser Himalaya

The project is situated in the Lesser Himalaya zone of Western Nepal. The local geology is dominated by the Kuncha Group, featuring robust phyllites and quartzites. This geological stability provides an excellent foundation for the 1.2 km headrace canal and the surface powerhouse near the Myagdi Khola riverbank.

Easy Accessibility

Accessibility is a key advantage, with the project site connected via a motorable road from Beni, the district headquarters. The route from Kathmandu via Pokhara and Beni is well-established, facilitating the transport of heavy electromechanical equipment and ensuring a streamlined construction timeline for the project team.

Community Synergy

The Malika Rural Municipality is a hub for agricultural and community-driven growth. By developing Middle Myagdi, Pinnacle Urja Invest is creating local jobs, improving rural electrification, and strengthening the local grid, all while respecting the natural flow and ecosystem of the Myagdi Khola valley.
