Neelum Jhelum Hydropower project inauguration planned
ISLAMABAD: As many as 96 per cent physical work on strategically important 969 MW Neelum Jhelum Hydropower Project (NJHP) has already been completed and its first unit would start supplying 242.25 MW to the national grid by February 2018.
Sources told here Sunday that the first unit would be followed by second unit in March while third and fourth units would be ready by April.
All the civil works including tunnel boring, installations of generators and turbines have been completed, they said.
The sources said completed with a cost of Rs. 404.321 billion (as per revised PC.1), 5.5 billion units of electricity annually with a cost of approximatelyRs.7 per unit and 15 years income would be spent on repayment of loans acquired to meet the cost of the project.
The project located in the vicinity of Muzaffarabad, the capital of Azad Jammu and Kashmir, is unique in its type in the country and was a difficult one as its all infrastructure including dam, water channels and power house is under ground and the river Neelum has been diverted 19.6 kilometers long underground tunnels.
The River Neelum has been diverted at Nauseri, 41 kilometers of here while the power house has been constructed at Chatter Kalas, 22 kilometers south of the city and after passing through turbines, water has been released in the river 4 kilometers further away from the site through another tunnel.
The composite gravity dam, 160 meters long, and 60 meter high, has been constructed underground at intake point Nauseri having the capacity to store 10 million cubic feet water with peaking reservoir of 3.8 million cubic feet to meet daily peaking requirements.
They said that water filling has been started in last week in the reservoir subsequent to the substantial completion of the dam.
Total storage of the dam is 8,207 acre feet upto design reservoir operating level of 1015 meter above mean sea level. After successful filling of the reservoir, the water would be diverted into the water way system by the end of 2017.
On completion, the project would contribute about five billion units of electricity to the national grid annually and annual revenue of the project was estimated to be Rs 50 billion, they said.
The project is an engineering marvel with 90 percent of the project being underground in the high mountain areas. The project consists of four units with installed capacity of 242.25 MW each.
