NEELUM JHELUM HYDROPOWER PROJECT

NEELUM JHELUM HYDROPOWER PROJECT
Organization	The Project is running through Neelum Jhelum Hydro-Power Company WAPDA, headed by a Board of Directors. The Chairman of the BOD is Chairman Wapda. Members of Wapda Authority and three General Managers are Members of the Board. Chief Executive Officer, the representative of Board of Directors, has his office at Lahore whereas Project Director (Chief Engineer) has his office at Muzaffarabad (AJ&K).
Location	Neelum Jhelum Hydroelectric Project is located in the vicinity Muzaffarabad (AJ&K). It envisages the diversion of Neelum river water through a tunnel out -falling into Jhelum river. The intake Neelum Jhelum is at Nauseri 41 Km East of Muzaffarabad. The Powerhouse will be constructed at Chatter Kalas, 22 Km South of Muzaffarabad. After passing through the turbines the water will be released into Jhelum River about 4 Km South of Chatter Kalas. Neelum Jhelum Hydroelectric Project has installed capacity of 969 MW. The Project will produce 5.15 Billion units of electricity annually. A concrete gravity dam 135 m long and 47 m high will be constructed on Neelum River at Nauseri. The dam is designed for over-topping. The dam will create a head pond of 8 million cubic meters which will allow a peaking reservoir of 2.8 million cubic meters to meet daily peaking of power for more than 4 hours. A six gate tunnel intake structure of 280 cumec capacity, will be connected with three conventional flushing surface basins installed at their end for taking sediment back into river. The total length of head race tunnel is 28.5 Km. A 15.1 Km stretch of the tunnel from the Nauseri be constructed as a twin tunnel system each with x-section of 43 Sq.m. The remaining head race tunnel down to the surge chamber will be a single tunnel having x-section of 82 Sq.m The tunnels are shotcrete lined with a concrete invert. The tunnel crosses Jhelum River approximately 380 m below its bed. The tunnel will be accessed by 7 Adits for removal of excavated spoil. The Surge Chamber consist of 341 m high riser shaft and 820 m long surge tunnel, Four steel lined Penstock tunnels 154 m long and having 3.8 m internal diameter will also be constructed. The under ground power Station will have 4 units with a total capacity of 969 MW. The Power Station will be connected by with Rawat Grid station through 500KV double circuit transmission line.

The Neelum Jhelum Hydroelectric Project is split into the following three main geographic areas.
1. NAUSERI AREA (ALSO KNOWN AS C1) A 47m high mass concrete gravity intake diversion dam and sedimentation basin near Nauseri is on the Neelum River. The dam has four large low-level gatesdesigned to pass floods up to the 1:1000 year recurrence period and also allow the reservoir to be drawn down for sediment flushing. The sedimentation basins are designed to trap sediments that could erode the turbine blades at the power house. The intake works are designed to divert up to 280m3/s into the headrace tunnels.
2. HEADRACE TUNNEL (ALSO KNOWN AS C2) The headrace tunnel is 28.5 km long and convers the water from the intake are3a at Nauseri to the Powerhouse area near Chatter Kalas. The tunnel crosses under high ground and also across the Muzaffarabad fault zone The first 15.1 km comprises of twin tunnels, each of x-section area 43m2 and the rest of the route, a single tunnel of x-section area 82m has been proposed. The tunnel will be excavated by drilling and blasting, with shot Crete and rock bolts for general support and full concrete lining at localized weaker zones. the invert of whole tunnel concrete lines. The tunnel crosses Jhelum River approximately 380 m below its bed.
3. CHATTER KALAS AREA (ALSO KNOWN AS C3) The headrace tunnel will feed four vertical-shafts Francis turbines with and installed capacity of 969 MW housed in an underground powerhouse. The water is discharged back into the Jhelum River near Zamainabad through a 3.5 km tailrace tunnel. Associated facilities include a transformer hall, surge shafts, access tunnels, a 500 kv switch yard and housing facilities for the operations and maintenance personnel.
PROJECT IMPLEMENTATION CONSTRUCTION Construction Contract was awarded, on July 07, 2007 to M/s CGGC-CMEC consortium China for implementation of the project at a cost of Rs. 90.90 billions including Rs. 46.499 Billions foreign component. Construction Agreement was signed on December 19,2007. Letter of commencement was issued on January 30, 2008. Contractor has mobilized at site. Preparatory works including construction of Contractors Camps aggregate crushing & batching plant, site access roads and site/test laboratory have been completed. Board of Director NJHPC has approved the deployment of Tunnel Boring Machines (TBM) for the Project on 23.11.2010. The contractor has arranged procurement of two TBMs from M/s Herrenknecht Germany. The deployment of TBM will certainly help to put the project on scheduled track and recover most part of delayed period envisaged for the commencement.

The main Progress of the Project works is as under:-
