With the growth of the economy the demand for power increases from varied sectors such as industrial units, commercial establishments, metallurgy, railways, telecom and households, etc. The power generation capacity needs to be scaled up by tapping various energy source such as the conventional coal based power generation or the other fuel source such as Gas based and renewable sources like wind, solar, bio-mass and hydro power. The next challenge lies in supplying power generation to places of consumption. The power generated can only be used if the transmission infrastructure is in place. Around 88 GW of power generation is targeted in the 12th five year plan. The investment in the transmission sector has to be planned simultaneously for smooth evacuation of power from centre of generation to consumption point.
A total of 1765 MW of power generation capacity was added during the month of December, 2013 which was much above the capacity of 105 MW scheduled to be added during the month. This entire capacity addition was contributed by the thermal sector with no capacity addition taking place in Hydro and Nuclear sector during the month of Dec, 2013. During the month of December, 2013, a growth of 6.73 per cent was registered in power generation compared to performance of Dec, 2012. Overall generation was 82,305.10 Million Units (MUs) as compared to 77,117.35 MUs achieved during the corresponding month of the last year. A growth of 14.64 per cent in nuclear generation, 22.41 per cent in hydro generation and 85.91 per cent in the imported power from Bhutan have been achieved in the month of December, 2013 as compared to the corresponding month of the last year. However, a negative growth of 4.69 per cent in thermal generation has been recorded for the same period.
POWER SHORTAGES REDUCED
During the month of December 2013, the energy supply shortage was reduced to 3.9 per cent with 82,600 MUs of requirement and 79,373 MUs of availability against the shortage of 8.9 per cent in Dec, 2012 with 84,866 MUs of requirement and 77,343 MUs of availability. Similarly, the Peak Demand shortage was reduced to 4.2 per cent with 132,786 MW of peak demand and 127,239 MW of peak met against the shortage of 9.6 per cent with 128,689 MW of peak demand and 116,394 MW of peak met in the corresponding month of the last year.
ONE NATION - ONE GRID - ONE FREQUENCY MISSION ACCOMPLISHED
On 31st December 2013, the southern power grid was connected to the national grid through commissioning of Raichur-Solapur 765 kV single circuit transmission line implemented by Power Grid Corporation of India Ltd. The country has achieved single grid status and has become one of the largest operating synchronous grid in the world with an installed capacity of 232 GW. Southern Grid Synchronous integration with rest of the national power Grid shall not only augment the inter-regional power transfer capacity of Southern region but also ease out the congestion being experienced in few transmission corridors. In the transmission sector, a total of 1613 CKM have been laid during the month of December, 2013 while scheduled target was only 281 CKM.
The power transmission sector is plagued with the usual issues associated with other infrastructure projects such as delay in project execution owing to land acquisition issues, clearances remaining pending with all concerned authorities leading to escalation of cost. Approximately 120 transmission projects have faced delays because of the developer’s inability to acquire land and get timely clearances from all stakeholders. Due to presence of many such constraints, the surplus power could not be evacuated from a region and provided to place of shortage. There are instances when power is being purchased at a higher cost while others remain under-utilised due to absence of evacuation mechanism i.e. to say the power transmission infrastructure.
NEW TRANSMISSION PROJECTS
Jyotiraditya Scindia, Minister of State (I/C) for Power has informed the Lok Sabha recently about the projects being planned / under execution to build new transmission lines so as to strengthen connectivity of Southern Grid with rest of the India grid. To strengthen connectivity of Southern Region with the rest of India grid, following interregional transmission lines have been planned and are under construction:
