Power development activities in NE

In the North Eastern Region, 41 power generation schemes totaling to 27753 MW are under survey and investigation.

North East News Agency

The total installed capacity in the North-East as on 1/11/2004 region is 2357.49 MW. Sector-wise, break-up given here under:

Sector Installed Capacity (MW) Hydro 1133.93

Thermal 1123.24

Wind 0.32

Nuclear 0.00

Total 2357.49

As per re-assessment studies carried out by the Central Electricity Authority (CEA), identified hydro potential ot the NE Region has been estimated as 58971 MW in terms of Installed capacity. Out of the above, 1095 MW has been harnessed so far while another 2244 MW is under construction after investment approval. The State-wise estimated hydro electric potential of North-Eastern region and its status of development is given below:

Survey and investigation

In North Eastern Region, 41 schemes totaling to 27753 MW are under Survey and Investigation. ^Stage-l clearance (under 3-stage clearance procedure) i.e. preparation qf pre-feasibility report by NEEPCO for 4 schemes (1310 MW) namely Hirit (50 MW), Papumpam (60 MW), Bhareli lift dam-II (600 MW) and Kameng dam (600 MW) with a total estimated cost of Rs. 10.69 crore and 2 H.E. schemes by NHPC viz. Siang (lower), 1700 MW and Siang (Intermediate) with an estimated cost of Rs. 14.11 crore have been recommended by CEA.

Under “50,000 MW Hydro Electric Initiative” 162 Hydro Electric Projects having aggregate installed capacity of 47970 MW were prepared by different agencies in the Central/State Sector. This included 62 Hydro electric Schemes with aggregate Installed Capacity of 30416 MW in North Eastern Region as per details below:

Preparation of DPRs

As a follow up of preparation of PFRs, it has been decided to take up implementation/ preparation of DPRs for low tariff (first year tariff below Rs. 2.50/kWh) schemes selected from PFRs. Out of 162 PFRs, 73 Hydro Electric Projects having aggregate installed capacity of about 33,000 MW have been identified for preparation of DPRs’ put of these 73 projects, 25 projects.lie in North Ea’stern Region as per details given below:

The power generated by the Central Sector Power Station situated in NER is evacuated through the regional transmission system. Presently, transmission system in NER consists of about 5,380ckt.kms.of interstate transmission lines including 919 ckt. kms. of interregional lines between NER & ER and 14 sub-stations. This transmission system caters to the, evacuation requirement of thermal/ hydro/ gas generating stations at Kathalguri (294 MW), Doyang (75 MW), Ranganadi (405 MW), Kopili (200 MW), Agartala (84 MW). The , North-Eastern Region is rich in hydro/gas resources and therefore, considering the future generation’ potential and the eco-sensitive geography, the transmission system had been planned in consultation with the beneficiaries, to take care of future needs of various generation projects like Kameng (600 MW), Damwe (520 MW) and Amguri (100 MW), total 1220 MW, with marginal investment.

The regional transmission system is the’backbone of NER Grid and following benefits have accrued from’ construction of transmission system:

(i) It inter-connects the networks of all the States in the region and facilitates inter-state transmission of Central sector power within the NER.

(ii) It facilitates and enables export of surplus power from Central Sector to other parts of the country, •particularly to the Eastern Region.

(iii) Facilitates integration of NER with the rest of the l National Grid.

POWERGRID is executing few transmission lines on deposit work basi/s, which include 132 kv Ziro-Daporijo-Along transmission system, 220 kV Kathalguiji- Deomali transmission system, and 132 kv Balipara-Khupi-Kimi transmission line.

To improve the performance of the power stations in the North Eastern Region through Human Resources development and training of the Power Sector personnel of the region, NPTI has established a Regional Power.Training institute at the temporary site of Narangi Complex of ASEB, Guwahati on 23.9.2003, launching, a training programme on APDRP from 23.9.2003 to 27.9.2003. The main Institute building and other infrastructure will be constructed at the permanent location at Kahalipara. The total job for construction of the infrastructure and furnishing of labs etc. has been awarded to PGCIL on turnkey basis.

North Eastern Electric Power Corporation Ltd. (NEEPCO) was constituted in 1976 under the Indian Companies Act, 1956 with the objective of developing the power potential of the North Eastern Region of the country through planned development of power generation projects, which in turn would effectively promote the development of the North Eastern Region. Since then NEEPCO has grown into one of the pioneer Public Sector Undertaking under the Ministry of Power, Govt. of India, with an authorised share capital of Rs. 3500.00 cr. and having an installed capacity of 1130MW (755 MW hydro & 375 MW thermal), which meets more than 60% of the energy requirements of the NE Region.

The main objectives of Corporation are to add to power generating capacity in the North Eastern Region by ensuring optimum utilisation of commissioner generation projects, to generate adequate internal resources ensuring justifiable return on investment, to continue sustained efforts to obtain the receivables, from State Electricity Boards/Departments, to execute and commission power projects, both hydro and thermal, within prescribed time frames, and to! undertake long term feasibility studies for optimum development of hydro power resources of the North Eastern Region.

During 91" Plan, NEEPCO added 754 MW (174 MW Thermal and 580 MW Hydro Power). The proposed capacity addition during the 10th Plan has been fixed as 155 MW(130 MW approx. Thermal and 25 MW Hydro). Out of this, Kopili H.E. Power Station Stage - II with one unit of 25MW has already been completed.

During the period from 1"April’ 04 to 30"’ Nov, 04, NEEPCO generated 2861 ML) from hydro stations against a target of 1730 MU and 1704 MU from thermal’stations (against a target of 1316 MU. The cumulative generation since Switchyard. Transformer.

Tuirial H.E. Project is situated in Aizwal district of, Mizoram. The Project proposes to develop the lowest possible stage of the Tuirial river system in Mizoram.’ Tuiriaf is a tributary of the river Barak, which! is one of the main river systems of the region flowing <nto the Bangladesh river system. The project was approved in July 1998 at an estimated cost of Rs. 368.72 cri Project is scheduled to be commissioned in July 2006. Tuirial H.E. Project is being financed by JBIC, Japan, Mis Electrowatt Engineering Ltd., of Zurich, Switzerland is the Review Consultant, of NEEPCO for this project.

The brief status of the project is as follows

A total length of 885 RM (Heading) of tunnel boring, out of 1550 RM has been completed.’ 14968 cum. concreting has also been completed, out of 55000 cum. Excavation and filling of Saddle Dam has been completed. 0.72 Lakhs cum. excavation of main Dam has been completed, out of 4.40 Lakhs cum. Out,of a total quantity of 192500 cum. of open excavation, 75000 cum. has been completed. Model Testing & Soil resistivity test of PH completed.

Ail the Project activities came to a total halt with effect from 9°’ June, 2004, due to law and order problem’and huge time and cost over run.

Ths revised cost estimate has been submitted to CEA for examination.

KAMENG H.E.PROJECT

Kameng H.E. Project envisages installation of Four units of 150 mw Francis Turbines in Kimi Power House on the left bank of the river Kameng in Arunachal Pradesh has been approved.
