Neelum-Jhelum project starts power supply to national grid
LAHORE: Neelum-Jhelum Hydropower Project on Monday started providing electricity to the National Grid on trial basis.
The first unit is contributing 60MW electricity to the system and will generate electricity to its full capacity to the tune of 242MW within next two days. Neelum-Jhelum Hydropower Project, located in Azad Jammu & Kashmir, is scheduled to be inaugurated on 13th April. The project has four units with cumulative generation capacity of 969MW.
The first unit has started electricity generation followed by the second, third and fourth units at one month interval respectively. Neelum-Jhelum Hydropower Project is an engineering marvel with 90 percent of the project being underground in the high mountain areas. The project consists of three main components i.e. a dam, water-way system comprising 52km long tunnels and an underground power house. The project will provide about five billion low-cost hydel electricity to the National Grid every year.
Annual benefits of the project have been estimated at Rs55 billion. For optimal utilisation of water and hydropower resources in the country, Wapda has been implementing a two-pronged strategy for the purpose. Under the strategy, not only the under-construction projects are being completed in the shortest possible time but new projects are also being initiated in both water and hydropower sectors.
Wapda is trying its best to award contracts for Mohmand Dam and Diamer Basha Dam within a year to supplement significantly towards existing water storage and hydropower generation capacities in the country.

Akhori dam and the Tarbela links
The proposed Akhori dam project will store about 8.6 billion cubic metres (seven million acres feet) of surplus Indus River water that is spilled after filling Tarbela reservoir during the monsoon season.
The stored water will be released for mitigating irrigation shortages during the dry season. The project is quite simple and includes a gated intake structure, a 37-km long water conveyance channel, a reservoir, a hydropower station, a spillway, dams and ancillary works.
The reservoir, called Akhori reservoir, will be developed by constructing dams across a valley near Akhori village. The valley is situated between Attock and Fatehjang towns, on the left bank of the Haro River at an approximate distance of 40 kilometres west of Islamabad. Detailed feasibility studies of the project have confirmed its technical and economic viability.
The intake structure will be designed for supplying the water from Tarbela to Akhori reservoir and it will be constructed on the southern periphery of Tarbela reservoir. The intake will function as an additional spillway of Tarbela that will release the water into the conveyance channel for delivering to and storing in Akhori reservoir.
The invert or sill of the intake structure will be at the same level as the crest of two existing spillways of Tarbela. The hydropower station will be designed for harnessing the hydro energy of the stored water before it is released from Akhori reservoir into the Haro River. The released water will join the Indus River downstream of Ghazi Barotha hydropower station.
It is believed that the raised intake sill can divert to Akhori reservoir sediment free water that is near the top surface of the full Tarbela reservoir. This can prevent sedimentation of Akhori reservoir and thus ensure its sustainability. But ultimately the sedimentation of Tarbela is expected to put an end to the availability the sediment free water which can jeopardise the said sustainability.
It is expected that Tarbela reservoir will stop the supply of the sediment free water to Akhori as soon as the accumulated sediment depletes the storage below Tarbela spillways. The annual sediment inflow (the sediment entering Tarbela reservoir) will become equal to sediment outflow (the sediment leaving the reservoir), that is the sediment equilibrium will be established, sometime after the storage below the spillways is depleted.
That eventuality will make Tarbela a run of river hydropower project and it will commence releasing the sediment laden water from all of its outlets, including the future intake structure meant for supplying water to Akhori dam project.
That is how the sedimentation of Tarbela will ultimately affect the sustainability of Akhori reservoir. That eventuality can be avoided only by preventing the accumulation of the sediment in Tarbela reservoir or by establishing the sediment equilibrium before the storage below Tarbela spillways is depleted.
Fortunately, the earlier sediment equilibrium can be established by returning to and releasing from Tarbela during the dry season the water stored in Akhori reservoir.
The release of the returned water during the dry season from Tarbela can scour and flush out increasingly larger portions of new sediment entering the reservoir every year and consequently it can establish the earlier sediment equilibrium. In principle lower the water level in Tarbela more the quantity of the sediment flushed out by the returned water.
Therefore, by rigorously monitoring the sediment and by prudently managing the release of water, a substantial remaining storage capability of Tarbela below its spillways can be saved permanently.
Apparently, there is no immitigable disadvantage of storing the Indus water in Akhori and releasing that water from Tarbela during the dry season. Even the previous sediment management studies indicated that the sedimentation of Tarbela can be mitigated by releasing additional water when Tarbela is at its lowest level.
Therefore, the idea or concept of returning the water from Akhori to Tarbela deserves a detailed investigation because it offers major benefits without affecting the anticipated benefits of Akhori dam project.
Feasibility studies ongoing.

The Executive Committee of the National Economic Council (Ecnec) on Tuesday approved Rs474 billion for the construction of Diamer-Bhasha Dam to help the country tackle two major issues—water shortage and power generation.
The Ecnec meeting, chaired by Prime Minister Shahid Khaqan Abbasi, approved the much-awaited funding for the project. The delay was due to reluctance from international financial institutions and China. The project is expected to complete in five years.
As per proposed plan, the dam will have a 6.4 million acre foot (MAF) live storage capacity and installed power capacity of 4,500 MW. After completion, the project will increase national water storage capacity of Pakistan from 38 days to 45 days and will enhance life span on downstream reservoirs including Tarbela Dam.
Regarding funding, the government will provide fund from the budget and Wapda will arrange commercial financing. A sizable amount will be allocated in the upcoming budget for the construction of the dam.
Past governments in 17 years had performed the ground-breaking ceremony of the project but civil work was not initiated due to lack of funding.

Formal Inauguration of 969 MW Neelum Jhelum HEP. April 13, 2018 when Unit # 4 was put online.
The most strategic and state-of-the-art Neelum-Jhelum hydropower project, located in AJK, has started generating 242 MW electricity. However, it will be fully functional by June-July this year to inject 969 MW electricity in the national grid.
The project with capacity of 969MW electricity will generate 5,150 gegawatt per hour at the levelised tariff of Rs. 13.50 per unit for 30 years. The annual benefits of the project have been estimated at Rs55 billion. Prime Minister Shahid Khaqan Abbasi has performed the inauguration ceremony of the project.
The Neelum-Jhelum Hydropower Project is a world class hydropower facility executed in the deep mountains where geology is neither predictable nor readable.
Never in Pakistan before, has such a complex project, which is one of a kind and is being branded as the new wonder of Pakistan, as only 10 percent of the whole project is on the surface, while 90 percent is underground with water-way system of 32 km tunnels (overall being ~52 km). Besides, transformer hall and powerhouse are also underground. The India's Kishenganga Dam of 330MW has been constructed on the same Neelum river. Since the water destined for Pakistan has been diverted to the Kishenganga project by India, therefore 10 percent less water will flow into the Neelum river. (ICA)
The project witnessed many upheavals on its way to completion and 86 percent of the project got completed without any financial closure. The cost of the project has been revised five times. Its initial cost was Rs80 billion but ended up at Rs500.343 billion. The Executive Committee of National Economic Council approved the project in 2002 at the cost of Rs84.502 billion for the initial design being prepared in 1997 while construction of project started on 30 January 2008. The cost of the project scaled up to Rs277.502 billion, which the ECNEC approved in 2012, and then once again its cost surged to Rs404.331 billion in 2015. And after that it again hiked to Rs500.343 billion.
The initial cost of Rs84 billion increased in the wake of the 2005 earthquake causing design modifications keeping in view the fault line passing through the Dam site thus considerably changing the scope of the project.
Furthermore, due to the rising value of dollar the cost escalated to over Rs277 billion. And then the cost of the project was revised upwards by 86 percent to Rs404 billion mainly because of the inclusion of duties, taxes which further pushed the cost to Rs500.343 billion because of the inclusion of IDC (interests during construction) till completion of the project and the cost of the consultant.
