Manali: The powerhouse of the 110MW Shanan hydroelectric project in Jogindernagar in Himachal’s Mandi district was flooded with high water flow after a huge bypass pipe connecting penstock burst on Saturday afternoon. Engineers and other staff working in the project swung into action to prevent the powerhouse from flooding completely. While power generation was stalled for hours, the situation was brought in control by the midnight. The valve of the penstock was closed and water was drained out till Sunday morning. Project superintending engineer Harish Sharma said the incident happened during testing when valve of one of the penstocks was opened and a bypass pipe burst while creating required pressure. “There was no loss to human life and nobody was injured. Power generation was affected for 13 hours. Now that situation is under control, we are testing all the machines one by one. The first machine is running at full load and second machine has also been started and working fine. Machine number three and four may have suffered some damages. Testing is continuing,” he said.
