About

Gandak Hydropower Station, located at Surajpura, Nawalparasi having installed capacity of 15 MW and annual design generation of 106.38 GWh was commissioned in 1979 AD and developed in assistance from Government of India and Government of Nepal with the total cost of NRs. 170 million. The project is initially developed with the dual purpose of hydropower and downstream irrigation in Uttar Pradesh, India. The station is canal drop type and the first low head (6.09m) power plant in Nepal. The weir is regulated by the Bihar State Government and the canal is shut down twice in a year for regular repair and maintenance. The operation of this power station is hence, affected by irrigation in Bihar and Uttar Pradesh.
