Transmission System Augmentation: A Crucial Link for India's Power Sector Growth
Metis Business Solutions PVT, Oct 2011, Pages: 200+
Power transmission sector in India is witnessing a massive system augmentation drive by adding capacities and infrastructure expansion plans in accordance with generation capacity addition. During the XIIth Plan, a total of 120,000[1] Ckt. Km of transmission lines and 295,000 MVA of transformer capacity are expected to be added. As per the latest estimates of MoP[2] 90,000 ckm transmission lines and 1,54,000 MVA transformer capacity is projected to be added in XIIth plan.
Transmission sector has grown in the country with a CAGR of 30 percent from the sixth plan. Huge capacity augmentation plans has lead to an increased demand for high technology driven lines and other equipments. Players in the equipment industry have been ramping up their capacities to cater to the expected future requirement. The country is now building lines at 800 KV HVDC level with first line (the Biswanath-Chiriyali-Agra bipole line) at this level expected to be completed by August 2013. Meanwhile, the central transmission utility, Power Grid Corporation of India Limited (PGCIL), has been developing a 1,200 KV transmission system at Bina in Madhya Pradesh. The major challenge in future is how fast the Indian entrepreneurs are able to acquire the technologies and source the skills for operating and maintaining it.
With huge generation capacity additions already planned, the development of national grid for stable power transmission is on fast track. In fact, it has been the main driving force behind the 765 KV and above voltage equipment segment.
The present inter-regional transmission capacity is 23,800 MW. According to the latest estimates by Central Electricity Authority (CEA), the interregional capacity is targeted to increase to 32,650 MW by March 2012, to 57,000 MW by 2015 and to 75,000 MW by 2017. The aim is to create highways that lead to the strengthening of national grid while ensuring overall efficiency in the delivered power.
Private sector entrepreneurship is slowly emerging by way of joint ventures with STUs and also fully-private transmission lines. The sector offers opportunities to established power transmission EPC contractors to evolve into owners and managers of transmission lines. Even smaller players could bid for projects through strategic alliances. Multinationals that have not tasted much success in the power generation (IPP) side, could look at power transmission instead. However the full fledged participation of the private sector is yet to achieve its mark. The government has targeted an investment of INR 2,09,500 crores in the 12th plan, out of which the private sector has a meagre share of INR 25,000 crores only.
Further in order to bridge the energy deficit faced by South-Asian countries a power grid linking South Asian Association for Regional Cooperation (SAARC) countries including India, Pakistan, Bangladesh, Sri-Lanka, Nepal, Maldives and Bhutan has been planned. A huge power generation potential consisting of mainly hydro for 21,000 MW in Bhutan, 84,000 MW in India, 83,000 MW in Nepal and 20,777 MW in Pakistan and gas potential in Bangladesh of 40 Trillion cubic feet.
India plays a lead role in planning the cross-border transmission links, including the methodology for implementing the cross-border transmission infrastructure. India has also been entrusted to ready a paper on the operation of stable and secure SAARC electricity grid, including scheduling and settlements proceeds for long-term and short-term cross border electricity trade.
Pricing reforms in transmission have been initiated by the Central Electricity Regulatory Commission (CERC), which are really crucial to ping in investments in the sector and would also result in rationalisation of tariffs in the long term. The new tariff structure based on the point-of-connection mechanism will provide appropriate signals for optimum load levels on the network in addition to siting signals for generation projects. This mechanism will assist in developing power markets, as tariff realisation would help in more efficient pricing of trade transactions.
Despite various developments and initiatives, transmission sector is still grappling with several challenges which include right of way problems, delays in acquiring clearances, grid indiscipline, inadequate equipment manufacturing and fast changing technologies leading to obsolescence.
The report targets to provide a comprehensive understanding of the major changes and issues in transmission focusing on the target achievement for both the 11th and the 12th plan along with a detailed study on transmission capacity augmentation.
