After the repair of the desander on the left side which was damaged by the landslide, water will be filled, electricity will be generated by sending water according to the flow of Tamakoshi, the goal of generating 456 megawatts of electricity in the peak hour.

The repair of the country's largest 456 MW Upper Tamakoshi hydropower station, which was damaged by the landslide on October 12, has been accelerated. Preparations have been started to start production from the power plant by keeping the deadline of January 10.
But Mohan Gautam, Chief Executive Officer of Tamakoshi Hydropower Center said that it will take at least 1 more month to bring the center into full operation after repairing it.
The repair of the two desander ponds of the power station is in the final stage, of which the desander on the left is being prepared for electricity generation by sending water directly from the dam site.
Purnagopal Ranjit, manager of the power station, told Kantipur that since the repair of the desander on the left side is about to be completed, electricity will be generated by directly sending water from Tamakoshi on 10th of December. The landslide completely damaged the power station. Desander and transmission line No. 46 tower was damaged. Ranjith says that if the construction of the tower is completed, then the damaged desander on the left side will be filled with water. He said that the headworks control center, which was damaged by the landslide, will be built only after electricity is generated. Ranjith said that for the time being, the reservoir will be filled and 2 out of 4 gates will be opened and water equal to the flow of the river will be sent to the power plant to generate electricity.
We start filling water at the dam site from 8/9 p.m. Out of the two, the desander on the left will be repaired and put into operation today,' said Ranjit, 'as in the past, water is not sent completely from the dam, we will send as much water as there is in the river to generate electricity.' It is expected to happen. After that, the production will also decrease as the water in the river will decrease.
'It will take one more month to completely repair the sand pond,' Gautam said, 'It will take more time to build the power house damaged by the earthquake, we will produce electricity at full capacity by repairing the desander.' He said that up to 130 megawatts can be sent.
'Tamakoshi's production has affected the demand for electricity across the country,' Gautam said, 'We are working day and night, preparing to produce electricity to meet the demand of peak hours.' He says that it will produce electricity.
The landslide damaged the control room, desander and the culvert that carries water from the dam to the desander on the lower right side of the upper Tamakosi power station dam. Gautam said that all the damaged structures are being repaired and preparations are also being made to call for tenders for new structures.
The design discharge (flow of water) of the Tamakoshi Hydroelectric Station is 66 cusecs. During the incessant rain last October, the flow of the Tamakoshi river reached 461 cusecs at the dam. According to the Power Purchase Agreement (PPA) signed by Tamakosi with the authority, the power plant should be shut down as soon as the water flow reaches 250 cusecs. Accordingly, the production of the hydroelectric power station has been stopped since October 11.
Tamakosi has the capacity to generate electricity worth Rs 4 crore per day. As it takes time to build Tamakoshi, Nepal Electricity Authority has been challenged to manage winter load.
