About

The Mai Khola Small Hydropower Station is a 4.5 MW run-of-river project located in Ilam District, Province 1, Nepal, developed and operated by Himal Dolkha Hydropower Company Pvt Ltd. It utilizes the flow of the Mai Khola River, a tributary of the Kankai Mai River, with an intake site at Bhorleni, Barbote and powerhouse near Narayanthan Khola in Ilam Municipality. The project was commissioned around January 2008, with final commercial operation completed in February 2011. The plant features two horizontal-axis Francis turbines, each with a rated capacity of 1.5 MW, operating under a gross head of approximately 42.65 m and a design flow of 7.5 m³/s. Key infrastructure includes a concrete gravity free flow weir, a side intake, a Dufour-type desilting basin, a rectangular RCC headrace canal, and an inverted D-shaped headrace tunnel. The power generated, approximately 18.3 GWh annually, is transmitted via a 2 km, 11 kV line to the Super Mai Hydropower Project switchyard. The facility employs modern synchronous generators and an oil-immersed transformer for voltage step-up. The project cost was approximately NPR 556.3 million (~USD 7 million).
