| 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.

The total length of head race tunnel is about 48 km. A 19.54 km stretch of the tunnel from the Nauseri site will be constructed as a twin tunnel system each with cross sectional exacavated area ranging from 52-58m2 . The remaining headrace tunnel down to the surge chamber will be a single tunnel having cross sectional area 100m2 approximately. The tunnel portion to be excavated with TBM will be shortcrete lined with a concrete invert while the drill and last portion of the tunnel will have full face concrete lining. The tunnel crosses under the Jhelum River at EI. 602.0, approximately 180m below Riverbed. The tunnel is accessed by 8 construction Adits for removal of excavated spoil. The Surge Chamber consist of 341m high riser shaft and 820m long surge tunnel, four steel lined Penstock tunnels 118 m long and having 3.8 m internal diameter will also be constructed. The underground power Station will have four units with a total capacity of 969 MW. The Power Station will be connected with Gakhar 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 60 m high Composite (Gravity + Rock fill) diversion dam and sedimentation basin near Nauseri is on the Neelum River. The dam has 3 no Radial gates and 2 flap gates designed to pass floods of 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 powerhouse. The intake works are designed to divert up to 280m3/s into the headrace tunnels. |
||
|
2.
MAJHOI/THOTA (ALSO KNOWN AS C2) The headrace tunnel is 48 km long including twin tunnel and conveys the water from the intake area at Nauseri to the Powerhouse area near Chatter Kalas. The tunnel crosses under high ground and also across the Muzaffarabad fault zone. A 19.54 Km stretch of the tunnel from the Nauseri be constructed as a twin tunnel system each with x-sectional area ranging from 52-58m2 and the rest of the route, a single tunnel of x-section area 100m2 approx, has been proposed. The tunnel portion to be excavated with TBM will be shortcrete lined with a concrete invert while the drill and blast portion of the tunnel will have full face concrete lining. The tunnel crosses under the Jhelum River at 602 msl, approximately 180m below Riverbed. |

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. 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. All the parts of TBM have been arrived at site and TBM assembly has substantially completed. The Soft Opening/Inauguration of TBM was held on August 06, 2012 and the Honorable Prime Minister of Pakistan graced the occasion by pressing the button. Both the tunnel boring machines (TBMs) have been assembled and tested. The operation of first TBM started on 28-01-2013 and second TBM started on 01-04-2013. Works required for Second Stage Diversion are ready. |
