Hydro power offers Ways to power up India’s future

For emerging ec­onomies, or for that matter even for the stable and rich ec­onomies, progress is linked with enough supply of power. Today, hydropower, th­ermal power and nuclear po­w­er, in a mixed manner, are the major sources of energy glo­bally. India has a power ge­neration capacity of 135,006 mw at present, which is not sufficient for the second fa­stest growing economy in the world. Power shortages have been identified as a key infrastructure bottleneck.


Consider hydropower generation.


 


India is a peninsula containing so many rivers and water bodies. But, hydropower is mo­­stly ge­nerated in south In­dia beca­use the Indo-Gan­getic plain is a flat terrain, not very conducive for setting up the hydr­­opower plants. In south In­dia, it’s possible but rainfall in that region is seasonal and also rivers are non-perennial. The monsoons between June and September account for nearly 80 per cent of annual rainfall over the country and are vital for the economy, being the main so­u­r­ce of water for agriculture and hydropower generation across the country.Nuclear power plants, said to be “the future of power” are good in some ways. But, there are various problems like non-availability of uranium, topography selection and environmental hazards, among others. If our plans for growth of nuclear power translate into action quickly because of the nation’s recent deals with nuclear energy rich nations like the US, UK, France and Russia, it would boost our power generation capacity.

 


Then, if we move our attention towards wind power, it is costly and seasonal winds also affect the performance in a huge manner. Solar power is a less developed option and has huge apparatus cost as well as cost of erection; also the success rate is very low. As of today, it is hydropower that is the major source of power generation. Hydropower projects based in south India account for 30 per cent or 11,­400 mw of the country’s installed capacity of 38,000 mw of this power source. To make matters worse, of the country’s total installed capa­city of 147,000 mw, only ar­ound 85,­000 mw is operati­onal at any given point of ti­me. India’s track record in ad­ding power generating capacity is poor: in the past five years the country has added 20,950 MW of capacity, ag­a­i­n­st a target of 41,110 mw. The limited addition of new power producing capacity, fall in hydropower generation in south India and higher demand for electricity in summer have already resulted in a severe power shortage across the co­untry. India plans to add 78,­577 mw by 2012, but according to government’s own so­urces, it co­uld miss this target by up to 60 per cent because of shortage of equipment and contractors, delays in technology alliances, lack of funds and natural cal­amities such as floods, among others.


The Indian electricity sector faces many other problems in trying to meet the ever-increasing demand-supply gap. Energy losses in India’s transmission and distribution sector exceed 30 per cent, which is one of the highest in the world. India’s power ministry estimates that about half of the electricity in the country is billed. The financial impact of technical and commercial lo­sses has been estimated at 1.5 per cent of GDP. Upgrading out-of-date transmission and distribution systems coupled with the need to reduce electricity losses and theft is driving the deployment of sm­art grid technologies in India. The methods to address these concerns demand substantial investments in adva­nced metering to reduce AT­&C (aggregate technical and commercial) lo­sses, in auto­mation to measure and control the flow of power to/from consumers on a near real-time ba­sis and in improvement of the system reliability and moving to a smart grid to manage lo­a­ds, congestion and shortfall in an intelligent manner.


The other concern is about getting trained manpower for operating the smart grid technologies, systems and related software. Our electrical engineering programmes do not cover these new facets of po­wer management. The po­wer industry in India is expe­c­ted to undergo a paradigm ch­ange, fuelled by legislative and regulatory activities. It would require power instrumentation engineers that wo­uld design and produce these new equipments.


The real challenge in the power sector in India lies in managing the upgrading of the transmission, distribution and metering sector efficiently and creating manpower to handle these challenges. In response to these challenges, it is heartening to note that the ministry of power has set up the India Smart Grid For­um as a public-private partnership, bringing in utilities, industry and academia.


Indeed in future, distribution and managing of po­wer is going to be a big busine­ss; a real challenge for the private sector, which desires to be in power industry and acade­mic institutions to completely overhaul the curriculum and delivery of education in electrical and instrumentation engineering.


It is estimated that the gl­obal market potential for sm­art grid equipment manufacturers and solution providers will be between $15 billion and $31 billion annually by 2014, with the value split am­ong three main business segments — customer applicati­ons; advanced metering infrastructure/smart meters and grid applications. India can certainly take a lead in this domain as it would enrich the economy and create new job opportunities.
