Heavy rain in the past 24 hours triggered landslides, uprooted trees and also affected power generation in some hydroelectric projects in the state.
Sources said power generation in some plants was stopped due to rising silt levels in the rivers on Saturday morning. However, the power plants resumed generation in the afternoon. A government official said if the rain continues and the silt level in rivers feeding the power plants rises, the generation would again be stopped.
According to information, power generation was stopped at the Parbati-III and HPSEBL-run Larji powerhouse, on the Beas river on Saturday morning, but was resumed within a few hours. However, a few small power plants run by Himachal Pradesh State Electricity Board Limited (HPSEBL) stopped generation due to heavy rain.
Generation was stopped in Satluj Jal Vidyut Nigam Limited (SJVNL) two power projects -1,500MW Nathpa Jhakri Hydropower station and the 412MW Rampur Hydropower Plant on Thursday but was resumed on Friday morning. Power projects have different parameters for shutting down the power generation due to silt, HPSEBL chairman and managing director PC Negi said. "All major projects are working. Generation was stopped in a few power plants but was resumed in a few hours," he added.
Besides hampering the power generation in the state, heavy rain also triggered landslide at many places. Power supply in parts of the state capital Shimla was disrupted as a tree fell on electricity cables near Clarks hotel on the Mall Road, besides damaging a portion of a building.
Heavy rains also blocked around 150 lateral roads, including National Highways 21 and 22, across the state. There have been reports of damage to property from Shimla, Kullu, Kinnaur, Mandi and Kullu districts. The water level in the major rivers of the state - the Satluj, Beas and Yamuna - which enter the neighbouring states of Punjab and Haryana has increased, a government official said.
The meteorological department has issued a warning of heavy to very heavy rain in next 24 hours. "Heavy to very heavy rains are expected in the next 24 hours," Shimla Met centre director Manmohan Singh said.
The state recorded 188mm of rainfall on Saturday. Paonta Sahib recorded 150mm of rainfall, Nahan 70mm, Dharampur 83mm, Una 70mm, Kasauli 61mm, Kandaghat, Sangrah and Rajgarh 49mm each, Berthin 45mm, Guler 44mm, Nagrota Surian 42mm, Arki and Rohru 40mm each, Solan 39mm, Aghar 38mm, Jhandutta 34mm, Mehre 33mm, Bangana 32mm, Jubbal 30mm, Pandoh and Kahu 27mm each, Kumarsain and Baldwara 26mm each, Bijahi 24mm and Nadaun 21mm.
HPSEBL projects in full swing
An HPSEBL official said the ongoing works in the entire Kinnaur and Lahaul and Spiti districts are in full swing. The work on 22kV sub-station at Akpa is going on at a decent pace. The work on under construction 22kV line on 66kV towers from Akpa to Pooh is also in progress. The land for construction of 66/22kV sub-station at Pooh will be acquired soon, he said. The foundation stone of a solar and wind power plant at Rangrik (Kaza) has been laid by chief minister Virbhadra Singh recently, he added.
