Two Mega Projects viz., Teesta (Sikkim) and Katch Tidal Project (Gujarat) presently under techno-economic appraisal by CEA have also been entrusted to NHPC for execution.

 

The corporation has completed so far 3220 ckt kms of EHV transmission lines, along with the associated sub-stations. Besides, a giant transmission network encompassing 3170 ckt kms including 800 KV class is also under execution under World Bank Assistance for transfer for power in the North-ern Region. In the snow-bound areas of J & K, a 400 kV Dulhasti Transmission Line is also under execution under Russian Assistance.

 

3 RURAL ELECTRIFICATION CORPORATION

 

The Rural Electrification Corporation (REC) was set up in July, 1969, with the primary objective of promoting rural electrification by financing rural Electrification Schemes and Rural Electric Coop-eratives in the states.

 

REC have given loans aggregating to Rs. 4742.49 crore by 1989?90 to States and State Electric-ity Boards for the Rural Electrification Schemes. Loans during 1989?90 aggregated to Rs. 724.60 crore.

The corporation is installing one more thermal units of 210 mW at Bokaro ?B?, Three Thermal Units of 210 mW each at Mejia and the fourth units of 210 mW each at the right bank of Maithon.

 

5 NORTH-EASTERN ELECTRIC POWER CORPORATION LIMITED

 

The North-Eastern Electric Power Corporation Ltd., was constituted in 1976 under the Compa-nies Act under the aim of developing the large electric power potential of the North-Eastern Region. The corporation is responsible for operation and maintenance of the 150 mW Kopili Hydro Electric Project which was commissioned in, June/July, 1988. The associated 220 kV and 132 kV transmission lines for supply power from this project to the constituent states of the region, namely; Assam, Manipur, Mizoram and Tripura, have also been completed.

The Corporation is presently executing the following projects: (i) Dovang Hydro-Electric Project (75 mW) Nagaland; (ii) Ranganadi Hydro Electric Project (405 mW) Arunachal Pradesh; (iii) Assam Gas Based Project (280 mW) Assam; (iv) Doyang Transmission Line Project; (v) Kanganaali Transmis-sion Line Project; (vi) Gohpur-Itanagar Transmission Line Project and (vii) 400 kV Transmission Line System associated with the Assam Gas Based Project.
