Development of Power Sector in North-Eastern Region Working Group on Power for 12th Plan Chapter 10 DEVELOPMENT OF POWER SECTOR IN NORTH-EASTERN REGION 10.0 INTRODUCTION As per the demarcation of Regional Power Grids of India , the North Eastern Regional Grid of the country comprises of 7 States; namely Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Tripura ; while State of Sikkim is the part of the Eastern Regional Power Grid . It is a land- locked Region with ninety eight percent of its border being international. The land -locked area which constitutes 8 percent of the total area of the country is connected with the main land through chicken-neck across West Bengal. In view of the slow growth of the region, special focus has been laid on economic development of North-Eastern Region and Sikkim. Accordingly strategies have been formulated for removal of infrastructure bottlenecks and creating a conducive environment for overall progress of the region including private investment etc 10.1 GENERATION PLANNING FOR NORTH-EASTERN REGION 10.1.1 Review of Capacity Addition Programme during 11th Plan As per the Mid Term Appraisal, Planning Commission had set a generation capacity addition target of 663 MW in NER and 1209 MW in the state of Sikkim during the Eleventh Plan. Out of this target 21 MW has been achieved in NER and 510 MW in Sikkim upto 30.9.2011. Capacity addition of 126 MW is likely to be achieved in NER during balance period of 2011-12. The State-wise details of capacity addition target and achievement (as on 30.09.2011) during Eleventh Plan are given in Table 10.1 below: Table 10.1 Capacity Addition during 11th Plan Target v/s Achievement in North-Eastern Region and Sikkim (All figures in MW) S.N State Target Achievement as on 30.09.2011 i Assam 537 0 ii Arunachal 0 0 Pradesh iii Meghalaya 126 0 iv Tripura 0 21 (Baramura GT-not included in Target) v Manipur 0 0 vi Nagaland 0 0 vii Mizoram 0 0 ix Total(NER) 663 21 x Sikkim 1209 510 407 | C h a p t e r 1 0 Development of Power Sector in North-Eastern Region Working Group on Power for 12th Plan 10.1.2 Installed Capacity as on 30.09.2011 The total Installed Capacity of NE Region (excluding Sikkim) as on 30.09.2011 was 2329MW comprising 1116 MW hydro and 990 MW thermal (including gas and diesel) and 223 MW from Renewable Energy Sources.

Comprehensive Scheme for Strengthening of Transmission and Distribution System in NER and Sikkim Based on the recommendation of CEA and in consultation with each state of NER and Sikkim, Powergrid has prepared detailed project reports for comprehensive schemes for strengthening of transmission, sub transmission and distribution system in each state of NER and Sikkim and also for inter-state transmission system in NER in June 2010. The estimated cost of the above schemes is about Rs. 11,348.5 crores. The schemes were to be implemented in two phases by 2015-16. The state wise break-up for cost of Transmission, Sub-transmission and Distribution schemes is given in Table 10.7 below. Table 10.7 (Rs Crores) Sl.
