A Note on the Power Transmission in the Area Including the Future Prospect of Transmission to Other States and Bangladesh
 

Meghalaya is a relatively fortunate State in the sphere of power generation. While most of the States in the country have serious shortages of power, Meghalaya is surplus and is in a position to supply power to its neighbouring States of Assam, Nagaland and Mizoram. This State, as discussed earlier, has a Hydro and Thermal Potential of about 3000 MW and 1000 MW respectively. Out of this potential, the State has been able to develop only 185.20 MW of hydro power so far.

TRANSMISSIONS AND TRANSFORMATION SCHEME:

Considering the rapid growth of load demand in the State, MeSEB formulated a scheme for taking up the augmentation and construction work of 132KV/220KV Grid sub-stations and transmission lines.  Due to this rapid load growth, MeSEB is facing shortage of power in the recent time. In order to enable MeSEB drawing its Central Sector power share from the NE grid, strengthening of its existing network is becoming inevitable. In view of this, numbers of transmission schemes have been formulated and targeted to be completed on a priority basis to meet the short-term demand of the State. The schemes being implemented are as follows: 

A.       Construction of the 132 KV transmission line from Sarusajai in Assam to Byrnihat in Meghalaya

         The project cost of the line is Rs. 1045.00 lakhs and is funded under NLCPR.  DONER at the cost of Rs. 9.78 crores approved the project.  The Meghalaya portion of the line has been completed and commissioned on 20-05-05 . The Assam portion of the line is being taken up by ASEB and the work is in progress.  This line on completion will enable the state to draw an additional 80 MW of power.

B.       Construction of the 132 KV transmission line from the Me.S.E.B. Sub-Station at Khliehriat to PGCIL Sub-Station at Khliehriat 

         The project is funded under NLCPR at the estimated cost of Rs. 286.00 lakhs. The work is in progress.

 C.      Construction of the 132 KV double circuit transmission line from Agia in Assam to Nangalbibra in Meghalaya

         The revised project cost of the line is Rs. 4693.65 lakhs.  The NEC funds the project.  The forest clearance for both the Meghalaya and Assam portion of the line had been obtained and forwarded to the NEC. The EFC memorandum for the construction of line had been submitted to the NEC in January 2006.

 D.      Construction of 220 KV transmission line from Misa in Assam to Byrnihat in Meghalaya along with the construction of the 220 KV/132 KV, 1 x 100 MVA at Byrnihat

         The Detailed Project Report was cleared by CEA and the work is to be executed by a Joint Venture between Me.S.E.B. and PGCIL.  MOU for this project was signed on the 08-09-05 .  The project is scheduled to be completed by March, 2009 and the project cost of the scheme is Rs. 243 Crores.

 E.      The 132/33 KV Sub-Station at NEIGHRIMS was commissioned on 6th May, 2005

 F.      Construction of the 132 KV/33 KV Sub-Station at Norbong, Byrnihat

         The project cost of the work is Rs. 465.00 lakhs.  The work is in progress.

 G.      Construction of the 132 KV/33 KV Sub-Station at Khliehriat

         The project cost of the work is Rs. 84.00 lakhs.  The work has been completed in all respect.

 H.      Augmentation of the 132 KV/33 KV Sub-Station at Nangalbibra

         The project cost of the work is Rs. 85.00 lakhs.  The work involves the augmentation of the Sub-Station from 17.5 MVA to 25 MVA and the work is in progress. 

OTHER TRANSMISSION LINE WORKS BEING TAKEN UP ARE AS FOLLOWS

 A.      LILO of 132 KV Stage IV – Sarusajai at Umtru Power Station

          NEC under NEC 10th Plan at the project cost of Rs. 3.87 crores funds this project and the work is in progress.  This line will improve the grid network and derive optimum benefit from the 100 MVA transformation capacity installed at Sarusajai to cater to the demand at Byrnihat.

 B.      132 KV Leshka Khliehriat line

         The project was approved for funding under ACA.  The NIT for the work is being issued and the material procurement work is in progress.

 C.      2nd circuit of the 132 KV single circuit line from Stage III Power Station to Stage IV Power Station

         The project will be funded by NEC under the NEC 10th Plan.  The revised project cost is Rs. 458.00 lakhs and the detailed project report had been submitted to NEC in January, 2006. The project is scheduled to be completed by March, 2007.

 D.       Construction of the  132 KV/33 KV Sub-Station at Lumshnong with LILO of the 132 KV Khliehriat – Panchgram line

            The DONER at the cost of Rs. 4.63 crores approved the project.  The work has been completed as per scheduled.  This project will cater to the growing industrial load demand around Lumshnong and will improve the quality of domestic power supply.

 SUB-TRANSMISSION AND DISTRIBUTION SCHEMES

 A.      Distribution Master Plan 

          This project is taken up in order to improve the existing transmission system and to provide quality and reliable power to the people of the state.  The project will also enable additional sale of energy and reduce the energy losses that in turn would generate additional revenue income to the Board.  The project is funded under NLCPR at an approved cost of Rs. 24.00 crores.  The target date of completion of the project is June 2006.

 B.      Improvement of power supply in Tura

         The project is funded under NLCPR at an approved cost of Rs. 12.03 crores and the work was completed in the month of October 2005.
