Tanahu Hydropower Limited has commenced preliminary construction work for the 126 MW Lower Seti Hydropower Project, including access roads and office infrastructure. The project, estimated to cost Rs 25 billion, will utilize water released from the existing 140 MW Tanahu hydropower facility. Plans include a 32-meter-high dam near Saranghat and a 6.8-kilometer tunnel leading to a powerhouse in Devghat. The project is expected to generate 520 million units of electricity annually. Land acquisition is underway, and the Asian Development Bank has provided a USD 3.5 million grant for detailed design and engineering.
