Test production of a 220-KV Chimkhola-Rahughat transmission line, constructed to connect power produced from hydropower projects at Rahughat basin of Myagdi district to central system, is being conducted.

A 13-kilometer long transmission line was constructed from Chimkhola to switchyard of Galeshwor-based Ragughat hydropower project to connect power produced from 35-MW Chimkhola-Mangale Rahughat, 48.5-MW Upper Rahughat, 21.3-MW Thulokhola and 23.5-MW Upper Thulokhola hydel projects to the central system.

Upendra Gautam, a representative of Tundi Power, promoter of Chimkhola-Mangale Rahughat and Upper Rahughat hydropower projects, said they are going to supply power in central system through 220-KV Dana-Khurkot transmission line from switchyard of Rahughat in a temporary manner until the completion of substation which is under construction at Raghuganga-3.

Physical infrastructures of Chimkhola-Mangale Rahughat and Thulokhola hydropower projects like dam, penstock pipe as well as different parts of equipment of powerhouse have already been examined.

Construction of the Upper Rahughat and Upper Thulokhola hydropower projects is in final phase. The electricity would be connected to the central line soon after the test. There are 39 towers from Chimkhola to Rahughat. The four hydropower projects making coordination have constructed structures to supply power through a single transmission line.
