Tangsibji mini hydel was disconnected on May 30, 2017. This plant lit around 43 houses in Tangsibji village in Trongsa in the 80s. The boulders that were dug out during the East-West highway widening works blocked the water at the intake point in the middle of December 2016. Mr. Karma Leki, Bhutan Power Corporation’s (BPC) Division Manager in Trongsa said that he has written to the Department of Roads (DoR) to have the blockade and damages cleared at the earliest as the boulders are huge and cannot be cleared by men.
This hydel power plant being closed does not have much impact on the life of the people in the village. However, Mr. Leki feels that it remaining functional is important as it was a gift to them from Japan and holds sentimental value. The energy that the plant generates is synchronized with the eastern grid. Mr. Phub Dorji, BPC’s assistant technician stated that this plant has never broken down before,unlike many other mini hydels in the country. He further said that the engine is in good condition and can resume generation once the block is cleared. This mini Hydel is one of 10 in Bhutan and it generates 37.5 KVA.
Mr. Taugay Choidup, Chief Engineer of DoR in Trongsa, stated that he was unaware that a mini hydel is located below the highway. He further stated that what they were informed is that there is an irrigation channel below and the contractor has left the cutting incomplete at a stretch near Zalamchu fearing disruption to paddy cultivation. The cutting is planned to resume after the village completes paddy cultivation.The mini hydel is located a little above the Tangsibji village and is about 10 minutes walk from the village road.
